Remembering 1987. Sticky sun & storms later Tuesday

Visible Satellite Loop Monday

The visible satellite loop from Monday showed a fairly sunny day across much of the state. A complex of showers and storms from South Dakota moved into western Minnesota late in the day. This unsettled weather will become more widespread as we head into Tuesday. 

Severe Threats: Tuesday & Wednesday

According to NOAA's SPC, there is a risk of strong to severe storms on Tuesday and Wednesday across parts of the region. At this point, there is a better chance for severe storms on Tuesday across much of Minnesota, while the threat on Wednesday shifts a little farther southeast. 

Simulated Radar 
The simulated radar through Tuesday evening shows our next storm system moving through the Midwest with not only the potential of strong to severe storms, but also the possibility of locally heavy rainfall. 
Heavy Rainfall Potential Ahead
The rainfall forecast  through PM Thursday shows heavy rainfall potential across the southern half of the state. Note that some locations could see as much as 1" to 2"+, which could lead to localized areas of flooding.
HILARY in the Eastern Pacific
The National Hurricane Center continues to track Hilary, which as of Monday afternoon was a category 1 hurricane with 85mph sustained winds. HILARY became the is the 8th named storm and the 4th hurricane of the 2017 Eastern Pacific Hurricane Season.
 Tracking HILARY
Here's the official track for HILARY, which has it potentially becoming a major hurricane at some point this week. If it does, it would be the 2nd major hurricane of the season. The other storm was FERNANDA, which developed into a category 4 storm!
HILARY Strength
Here's the model outlook for HILARY, which shows a trend towards strengthening over the next few days, but only a few bring this to category 3 strength or higher, which is considered to a major hurricane. The majority of the models keep this storm at a category 1 or 2 through the week.
Eastern Pacific Outlook: Next 5 Days
Weather conditions in the Eastern Pacific continue to remain active as NOAA's NHC is keeping an eye on 2 other waves of energy west of  HILARY, which are both named. GREG continues well off to the west, but IRWIN has also developed, which is the 9th named storm of the season!
Tracking GREG
According to NOAA's NHC, GREG was still a tropical storm with sustained winds of 45mph. The good news is that this storm is not expected to pose a threat to any major land mass and could be a tropical depression by midweek.
 Tracking IRWIN
IRWIN became the 9th named storm of the 2017 Eastern Pacific hurricane season and could become the 5th hurricane of the season! The good news with this storm is that it is not expected to impact any major landmass. 
 Atlantic Outlook: Next 5 Days

Meanwhile, the Atlantic basin looks to remain quiet over the next 5 days. Stay tuned...


2017 Lightning Fatalities 

According to NOAA's NWS, there have been 7 lightning fatalities so far this year, the most recent coming from North Carolina on July 18th as a 40-some year old man was walking to store. Note that 4 of these deaths have occurred in Florida, which is considered to be the lightning capital of the United States. 

Lightning Deaths Over the Last 10 Years

According to NOAA's NWS, lightning kills an average of 47 people each year in United States! Over the last 10 years, 310 people have died from lightning and what is interesting is that nearly 79% have been males!

Lightning Safety: Myths & Facts

Did you know that lightning is nearly 5 times hotter than the surface of the sun? Here are a few interesting myths and facts from NOAA's NWS regarding lightning:

Myth: If you're caught outside during a thunderstorm, you should crouch down to reduce your risk of being struck.
Fact: Crouching doesn't make you any safer outdoors. Run to a substantial building or hard topped vehicle. If you are too far to run to one of these options, you have no good alternative. You are NOT safe anywhere outdoors. See our safety page for tips that may slightly reduce your risk.

Myth: Lightning never strikes the same place twice.
Fact: Lightning often strikes the same place repeatedly, especially if it's a tall, pointy, isolated object. The Empire State Building is hit an average of 23 times a year

Myth: If it’s not raining or there aren’t clouds overhead, you’re safe from lightning.
Fact: Lightning often strikes more than three miles from the center of the thunderstorm, far outside the rain or thunderstorm cloud. “Bolts from the blue” can strike 10-15 miles from the thunderstorm.

Myth: Rubber tires on a car protect you from lightning by insulating you from the ground.
Fact: Most cars are safe from lightning, but it is the metal roof and metal sides that protect you, NOT the rubber tires. Remember, convertibles, motorcycles, bicycles, open-shelled outdoor recreational vehicles and cars with fiberglass shells offer no protection from lightning. When lightning strikes a vehicle, it goes through the metal frame into the ground. Don't lean on doors during a thunderstorm.

Myth: A lightning victim is electrified. If you touch them, you’ll be electrocuted.
Fact: The human body does not store electricity. It is perfectly safe to touch a lightning victim to give them first aid. This is the most chilling of lightning Myths. Imagine if someone died because people were afraid to give CPR!

Myth: If outside in a thunderstorm, you should seek shelter under a tree to stay dry.
Fact: Being underneath a tree is the second leading cause of lightning casualties. Better to get wet than fried!

PRELIMINARY 2017 Tornado Map

It certainly has been a fairly active first half of 2017 with 1190 preliminary tornado reports through July 23rd. Note that this is the most tornadoes through July 23rd since 2011, when there were 1,662 reports. The map below shows the distribution of the tornadoes so far this year. 

PRELIMINARY 2017 Tornado Count

According to NOAA's SPC, the PRELIMINARY 2017 tornado count is 1190 (through July 23). Note that is the most active year for tornadoes since 2011, when there were 1,662 tornadoes. Keep in mind there was a major tornado outbreak in the Gulf Coast region from April 25-28, 2011 that spawned nearly 500 tornadoes, some of which were deadly. That outbreak is known as the Super Outbreak of 2011 and has gone down in history as one of the biggest, costliest and one of the deadliest tornado outbreaks in history.


National Weather Hazards Ahead...

1.) Excessive heat across portions of the Middle Mississippi Valley, the Lower Mississippi Valley, the Southern Plains, the Ohio Valley, and the Tennessee Valley, Thu, Jul 27.
2.) Heavy rain across portions of the Southwest, Central and Southern Rockies, and the Central and Southern Plains, Thu-Fri, Jul 27-Jul 28.
3.) Heavy rain across portions of the Northeast, Thu-Fri, Jul 27-Jul 28.
4.) Heavy rain across portions of the Southeast and the Mid-Atlantic, Sat-Sun, Jul 29-Jul 30.
5.) Flooding occurring or imminent across portions of the Upper and Middle Mississippi Valley and the Great Lakes.
6.) Flooding possible across portions of the Central and Southern Plains, the Central and Southern Rockies, the Central Great Basin, and the Southwest.
7.) Flooding likely across portions of the Middle Mississippi Valley.
8.) Slight risk of much above-normal temperatures for portions of the Great Basin, the Northern Plains, the Northern Rockies, California, the Pacific Northwest, and the Southwest, Tue-Sat, Aug 1-Aug 5.
9.) Severe Drought across parts of the Great Plains, Arizona, California, and Hawaii.


"Hi-Line farmers feeling drought's burn"

"The life had been fading from Grant Zerbe's stunted chickpeas for the better part of a month, and now drought’s hot breath was burning through the final green inch of every plant stem.The Montana farmer’s worst growing season in 30 years was coming to a brutal end. There are few crops to harvest in the region, and with a lack of food and water, unwanted livestock are headed to auction. “Normally, we’d be getting 1,200 pounds to an acre,” Zerbe said. “The crop would be so thick you couldn’t see the ground.” Northeast Montana is experiencing the worst drought in the country. On U.S. Drought Monitor maps, the Montana portion branded "extreme" spans 350 miles. Combined with drought in the Dakotas, Montana’s losses contribute to what the U.S. Department of Agriculture expects to be a 64 million bushel loss in wheat production. Durum, a specialty crop for Montana and North Dakota, is expected to be down in bushels 45 percent from last year."

EXCEPTIONAL Drought in Montana

According to the US Drought Monitor, parts of Montana are now under an EXCEPTIONAL Drought. While nearly 2% is considered to be in an EXCEPTIONAL drought, 22% is under an EXTREME drought. Also, nearly 65% of the state is considered to be either abnormally dry or in some type of drought.

EXCEPTIONAL Drought in North Dakota

According to the US Drought Monitor, parts of North Dakota are now under an EXCEPTIONAL Drought. Interestingly, this is the first time since 2006! While a little more than 6% is considered to be in an EXCEPTIONAL drought, more than 40% is under an EXTREME drought, which is up from the nearly 36% last week. Also, nearly 94% of the state is considered to be either abnormally dry or in some type of drought.
Rain Needed to End Drought
Exceptional and Extreme drought conditions are in place over parts of Montana and North and South Dakota due to several days/week of hot and dry weather. The image below suggests how much rain would be needed to end the drought, which suggests nearly 6" to 12" or more!

US Drought Monitor
According to the US Drought Monitor, drought conditions from July 11h to July 18th worsened slightly across the nation. Note that EXCEPTIONAL and EXTREME drought conditions (located across parts of Montana and parts of North and South Dakota increased from last week


National Weather Outlook

Here's the weather outlook through the early weekend suggests that stormy weather returns to the Midwest with strong to severe storms and locally heavy rainfall midweek. Monsoon storms continue in the Southwest with a few strong storms and areas of locally heavy rain. Late week and early weekend, another round of storms and heavy rain will move in along the Eastern US.

Severe Threats Tuesday, Wednesday & Thursday
According to NOAA's SPC, there is a SLIGHT risk of severe storms across parts of the Midwest on Tuesday, while another SLIGHT risk of severe storms has been posted across parts of the Midwest/Great Lakes/Ohio Valley on Wednesday. In these areas, large hail, damaging winds and locally heavy rains will be possible in these areas.

Excessive Rainfall Potential Tuesday & Wednesday

According to NOAA's WPC, there is a risk of excessive rain on on Tuesday across parts of the Western US and Midwest. Some of the same areas could see heavy rain and flooding once again on Wednesday.

Localized Heavy Rain Threats

Excessive rainfall potential is in place over parts of the Midwest over the next couple days and the rainfall forecast suggests some 1" to 2"+ rainfall tallies through AM Saturday. Areas of heavy rain could lead to localized areas of flooding. 


Monsoonal Storms

WOW - take a look at this video that @WesCallisonTNN tweeted a couple of days ago, which shows a monsoon storm developing and dumping a huge blob of heavy rain over some of the mountains in Arizona. These types of heavy rainfall events can lead to dust storms and flash flooding.

 Monsoon Storms Continue

Here's the simulated radar from Tuesday to Saturday, which shows the potential of daily monsoon storms continuing across the region. Note that some of the storms could be a little on the strong side with gusty winds, dust storms and locally heavy rain, which could lead to localized flooding. The 5 day rainfall forecast below suggests that some areas could see up to 1" of rain or more through the end of next week!


"Crews stop spread of huge California wildfire near Yosemite"

"Crews contending with triple-digit temperatures slowed the spread of an aggressive wildfire that destroyed dozens of homes in a rural area of California near Yosemite National Park, officials said Sunday. The blaze burning for a week has scorched just over 119 square miles (308 square kilometers) of dense brush and dead trees in the Sierra Nevada foothills. Many evacuated residents were allowed to return, but flames continue to threaten about 1,500 homes in Mariposa County. The fire was 45 percent contained, but officials said it could take crews another two weeks to fully surround it. "They are still out in front of an uncontrolled fire, but the fire isn't moving at 30 mph (48 kph). The fire is crawling along," fire spokesman Brandon Vaccaro said Saturday. Flames spared Mariposa, a historic Gold Rush-era town, but more than 130 buildings, including 63 homes, were destroyed. More than 5,000 firefighters fought the blaze using air tankers and fleets of helicopters and bulldozers."

DetWiler Fire - Near Yosemite - California

The Detwiler Fire located near Yosemite National Park in California has ballooned to a very large 76,500 acre fire since Sunday, July 16th. This fire has already consumed more than 130 structures; 63 homes, 67 minor structures and 1 commercial structure. A number of other homes and smaller structures have been damaged as well, but 1,500 other structures are being threatened now. There are almost 4,200 people working on the fire and it is only 50% contained at this point . Higher humidity levels are helping create better fire fighting conditions.

Lodgepole Complex - Montana

According to Inciweb, one of the largest fires currently burning in the Lower 48 is the Lodgepole Complex located 52 miles NW of Jordan, MT. This particular fire has consumed a whopping 226,000 acres and is expected to be fully contained by Wednesday, August 2nd. This particular fire started on Wednesday, July 19th and quickly spread as hot, dry and windy weather created extreme fire behavior. Gusty winds are still posing a concern for the fire.

Ongoing Large Wildfires

Here's a look at the current wildfire map across the country. Recent hot and dry weather has helped to spark several wildfires across the Western US, while a few have also been popping up in the Eastern US.

Here's a list of all the current large wildfires from Inciweb:

National Smoke Analysis
Here's the projected wildfire smoke concentration for midday Tuesday, which suggests that smoke from wildfires burning across parts of Canada and the Western US could continue to linger around the Upper Midwest/Great Lakes region. There also appears a very high concentration of smoke from fires burning across the western half of Canada. If you are in these areas, air quality could be a little poor, but these areas may also be enjoying very interesting looking sunrises/sunsets, which tend to look hazy or reddish-orange.
Remembering 1987. Sticky sun & storms later Tuesday
By Todd Nelson, filling in for Douglas

It's been 30 years since the 1987 Homer Hanky was being waved. Big bats from Dan Gladden in game 1 and Kent Hrbek in game 6 along with a loaded pitching staff that included Bert Blylevin and MVP Frankie "Sweet Music" Viola helped bring home the 1st World Series for the MN Twins that year. My ears are still ringing from the roar in Dome. WOW - What a year!

It has also been 30 years since the 1987 Twin Cities Superstorm when 10 inches of rain fell at the Twin Cities Airport from July 23rd to 24th. This caused massive flooding across parts of the metro, which lead to nearly $30 million in damages and 2 flood related deaths.

1987, no question, was an interesting summer.

Sticky sunshine returns Tuesday with dewpoints spiking in the upper 60s and low 70s. This could help spark a few strong to severe storms later with rounds of heavy rain overnight. Some in southern Minnesota could see as much as 1 to 3 inches of rain through early Wednesday, but Chamber of Commerce days look to return Thursday through Saturday. Soak it up!

Extended Forecast

TUESDAY: Sticky. Strong storms late. Winds: S 8-13. High: 87.

TUESDAY NIGHT: Scattered showers and storms with locally heavy rain. Low: 71

WEDNESDAY: Lingering storms early. PM clearing. Winds: NNW 5-10. High: 84

THURSDAY: Nice day. Sun returns, less humid. Winds: NNE 5. Wake-up: 65. High: 82

FRIDAY: Another beauty. Sneak out early. Shh! Winds: ESE 5. Wake-up: 63. High: 83

SATURDAY: Keep it coming. Winds: SW 5-10. Wake-up: 64. High: 84.

SUNDAY: Warmer, more humid. A few rumbles. Winds: W 5. Wake-up: 66. High: 86

MONDAY: Passing clouds. Looks dry. Winds: S 5-10. Wake-up: 70. High: 82.

Weather Outlook For Tuesday

After a couple of cooler, more comfortable days across the state Sunday & Monday, the heat and humidity will return on Tuesday with highs approaching 90F across the southern and western part of the state. Dewpoints will also warm into the 60s & low 70s across much of the state, which will make it feel quite sticky once again.

Weather Outlook For Tuesday
A southerly wind will develop and strengthen a bit ahead of our next storm system that will move through Tuesday. Winds will be sustained around 10-15mph with gusts approaching 20mph across the southern half of the state. This wind will also help to transport the higher dewpoints back into the region.
Weather Outlook For Tuesday
Here's the weather depiction for midday Tuesday, which shows an increase in precipitation potential across the central and northern part of the state. Note that the best potential for thunderstorm activity won't arrive until late afternoon/evening.
UV Index for Tuesday - HIGH

Despite there being more clouds across the region, the UV Index will still be considered HIGH on Tuesday, which means that it will only 20 to 30 minutes or less to burn unprotected skin. With that said, if you are planning on spending any extended length of time outside, make sure you wear appropriate attire and lather on the sun block!


Weather Outlook For Wednesday

A cold front will continue to push south of the region on Wednesday with scattered showers and storms drifting southeast along with it Cool and somewhat less humid air will begin settle south behind the front, which will be a little more evident later Wednesday and certainly into Thursday. 

UV Index for Wednesday - VERY HIGH

As scattered showers and storms sag south through the region during the day, areas of sun will begin to pop out later. With that said, the UV Index for Wednesday is expected to be HIGH once again, which means that your skin could burn in 15 to 20 minutes or less!


Minneapolis Temperature Outlook

Here's the temperature outlook through August 8th, which shows temperatures hovering in the 80s through the rest of the month and into the early part of August. Keep in mind that the average high in the Twin Cities through August 8th is 82F, so we should be pretty close to average.

8 to 14 Day Temperature Outlook

According to NOAA's CPC, the extended temperature outlook from August 2nd to August 5th suggests cooler than average temperatures moving into much the Upper Midwest as we head into the early part of August.


Extended Temperature Outlook

According to NOAA's CPC, the extended temperature outlook through August 6th shows that a large chunk of the Central US will be dealing with cooler than normal temperatures, while the western part of the country will still be above average.

Extended Temperature Outlook

Here's the extended 850mb temperature anomaly loop into early next. This describes how warm or cold (from average) mid/low level temperatures will be over time. Note that the warmer oranges and reds will begin to settle in along the northern tier of the nation through the end of the month/early August, but there some cooler than average temps settling in across the Central US as well.


Weather Outlook Ahead

The weather outlook over the next couple of days shows stormy weather continuing across parts of the Eastern US and the Desert Southwest, but another round of strong to severe storms with locally heavy rainfall will also move in across the Upper Midwest through midweek.

5 Day Precipitation Outlook

According to NOAA's WPC, the next several days could produce areas of locally heavy rainfall across many areas from the Desert Southwest to the Midwest and eastern half of the country. Some of the heaviest rainfall could add up to as much as 1" to 3"+, which could also lead to areas of localized flooding.


"As The Climate Changes, Kenyan Herders Find Centuries-Old Way Of Life In Danger"

"Out here, in West Pokot County, Kenya, the landscape looks like Mars — red clay, rocks, and in the distance, a mountain so bare it looks like a giant boulder. Stephen Long'uriareng, 80, has walked two hours to bring her two cows and goats to this watering hole. It's really just a dam carved out the earth, where the rain water mixes with mud and turns into a dark brown color. This is not the place Long'uriareng remembers from her youth. "This whole place used to be green with a lot of pasture. There was nothing being experienced like drought," she said."

"This mayor is leaving politics to fight climate change full-time"

"Like many communities skirting the U.S. coastline, Hoboken, New Jersey, wasn’t built on solid ground. Many of its charming brick buildings, historic piers, and apartment towers stand atop what was once a low-lying tidal marsh — a grassy, muddy buffer along the Hudson River, designed by nature to absorb high tides and storm surge like a sponge. Early developers drained the marshlands in the 1800s to make way for modern Hoboken: the birthplace of singer Frank Sinatra, the location of TLC’s Cake Boss, and home to 53,000 people packed within the 1.25-square-mile city limit. Across the river, Manhattan’s glassy skyscrapers sparkle in the summer sunlight."

"A super-simple strategy may be key to fighting climate change"

"A key strategy in the fight against climate change is slowing the rapid destruction of the world’s forests. When trees burn or decompose, they release carbon. About 10 percent of the greenhouse gases emitted every year are from this newly freed carbon rising into the atmosphere. In recent years, developed countries have committed billions of dollars to help developing countries prevent deforestation. Some of the funds have been used to pay landowners not to cut down their trees. Part of the goal is to give landowners income that isn't dependent on clearing land for agriculture or selling timber to meet big expenses."

"How does climate change impact you?"

"Most people in Idaho believe climate change will not impact them. They think polar bears may be in trouble, or that people that live along the coast may have problems, but they don’t think it will cause problems in Idaho anytime soon. In reality, climate change is already impacting most of us in one way or another. Anyone who buys insurance is seeing the cost increase. More storms, more fires, more floods; about 5 times more severe weather events than we had 50 years ago. This means higher insurance premiums. Federal agencies are having to cut back on road maintenance, campground maintenance and nearly everything else because they are spending nearly half of their budget fighting fires. City, county, and state governments are having to increase taxes and/or reduce services with the added costs from severe storms."

"Britain faces a future of record-breaking wet winters, potentially leading to more of the widespread flooding seen in recent years, according to new modeling that incorporates changing climate patterns. England and Wales now have a 34 percent chance of record rainfall between October and March, the study by the government’s Met Office said on Monday. In 2013, heavy rain deluged parts of Cornwall and the south east. That was followed by three named storms that flooded some of Cumbria, Lancashire and Yorkshire in December 2015, while Storm Angus battered parts of Britain last November."

Comfortable Monday - Hot And Sticky By Tuesday

Twin Cities Dew Points So Far This Summer
Last week was certainly a muggy week in the Twin Cities, with maximum dew points each day in the 60s and 70s. In fact, we saw three days last week with a dew point of 70 or higher - the highest being both Tuesday and Wednesday with a max dew point of 72. So far this summer in the Twin Cities (since June 1st) we have seen 21 days with a dew point of 65 or higher - seven of those days seeing dew points of 70 or higher. The highest so far was on the 12th of this month with a dew point of 74. For comparison, the highest dew point last year in the Twin Cities was 77, with the all-time highest being 82 (which occurred in July of 2011).

Comfortable Today - Hot And Sticky By Tuesday
By DJ Kayser, filling in for Douglas

Some like it… muggy?

I know I personally don’t, but muggy weather and summer always go hand in hand. If you are a fan of muggy weather, you certainly enjoyed last week as all but one day saw the dew point at or above 65 at some point during the day. Since June 1st, 21 days have had a dew point at or above 65 in the Twin Cities, and a third of those days have had a 70+ degree dew point. That’s still better than parts of Iowa, which saw dew points in the 80s last Thursday!

Sunday gave us a break from the muggy weather, and that comfortable weather continues today, with highs around 80 and dew points hovering in the 50s. As we head toward the middle of the week, however, sticky weather returns with storms likely. Some of those storms could be strong, with the potential of heavy rain as well. Pleasant weather then returns in the form of Canadian high pressure late in the week.

I'm sure we won't be done with the summer heat and humidity though – we still have August to get through, and the State Fair is only a month away!

Extended Twin Cities Forecast
MONDAY: Sunny and comfortable. High 80. Low 66. Chance of precipitation 0%. Wind SE 5-10 mph.
TUESDAY: Muggy. Late day storms. High 91. Low 72. Chance of precipitation 60%. Wind S 5-15 mph.
WEDNESDAY: Storm chance lingers in southern MN. High 83. Low 65. Chance of precipitation 50%. Wind NW 5-15 mph.
THURSDAY: A very pleasant, sunny day. High 82. Low 65. Chance of precipitation 0%. Wind N 5-10 mph.
FRIDAY: Sunny. Nice end to the week. High 83. Low 66. Chance of precipitation 0%. Wind SE 5-10 mph.
SATURDAY: A touch muggier. Mainly sunny skies. High 85. Low 67. Chance of precipitation 20%. Wind SW 5-10 mph.
SUNDAY: Early morning storms. Turning sunny. High 81. Low 58. Chance of precipitation 30%. Wind NW 5-10 mph.

This Day in Weather History
July 24th

1987: A historic deluge ends in the Twin Cities. Two-day totals include over a foot of rain at Bloomington. Nearly 10 inches falls in downtown Minneapolis, and near 9 inches is recorded in St. Paul. At one time the water reaches a depth of 13.5 feet on I-494 near East Bush Lake Road. I-494 in Bloomington would be closed for nearly 5 days.

1891: Heavy frost hits Elkton in Mower County in southeast Minnesota. The frost kills all vegetable crops. The low in Elkton is 34, and the Twin Cities have a low of 49.

Minnesota Weather Outlook

Another nice day is expected across the state Monday, with highs in the 70s in most spots. Areas along Lake Superior will likely stay in the 60s, with areas of western Minnesota reaching the low 80s. The hot weather will stay out in the Dakotas, where Pierre is likely to top 100.

As we head toward the overnight hours, however, storms are expected to form across the Dakotas and eventually move into parts of western Minnesota. These stronger storms may be capable of damaging winds.

A severe risk will exist on Tuesday as well as the cold front moves through the upper Midwest. The greatest risk will be during the overnight hours across the region with damaging winds. However, hail and tornadoes will be possible, especially if any storms pop during the afternoon and evening.

Isolated severe storms will continue to be possible across southeast Minnesota Wednesday as the cold front continues to move through.

Heavy rain will be possible with these storms as well. The models are showing some of heaviest will be possible across southwest and central Minnesota, with the potential of over 2" in St. Cloud.

After the rain expected toward the middle of the week, the next rain chance will move in Saturday Night as a cold front sweeps through the state. After that, modes indicate drier weather through the first week of August.

The warmest weather over the next couple weeks appears to be Tuesday, when temperatures will be pushing 90 in the Twin Cities. Otherwise, models are showing highs at or below average into the beginning of next month.


National Weather Outlook

Monday Forecast

Finally the heat is starting to break across portions of the central U.S. as we head into Monday (at least for a day) as temperatures will only be around 90 in St. Louis. Monsoonal storms will continue to be possible across parts of the Southwest, meanwhile a frontal system brings the chance of storms from the Northeast to the southern Plains.

The heaviest rain through Friday will be in the eastern U.S., where some areas from New York to the Carolina coasts could pick up two inches or more of rain. Heavy rain will also be possible in parts of the Southwest thanks to monsoonal storms.


How Often Do 80+ Dew Points Occur?
Last week parts of Iowa reached the 80s for dew points. How common is that around the nation? As you can see from this map from the Iowa Environmental Mesonet, the most common areas to see them is around the Gulf Coast, but areas into the upper Midwest do tend to see some each year.

The Total Solar Eclipse Is Coming!
We are now less than a month away from the total solar eclipse, and more anticipation is being built up for it. Have you ever looked at the path of the peak of the eclipse and wondered why it moves west to east? Popular Science has the answer why that is: "This summer, for the first time since 1918, a total solar eclipse will cut a path across the mainland United States. On August 21, everyone in North America will be able to watch the moon pass in front of the sun, blotting out some or all of its light (depending on where you live). People near Lincoln City, Oregon will see the total eclipse around 9:05am PDT. Then the path of totality slants eastward, finishing up in South Carolina at 2:43pm EDT. But hold on—if the moon rises in the east and sets in the west (or pretty close to it, anyway), why does the shadow of an eclipse move from west to east? The answer, says Angela Speck, an astronomer at the University of Missouri, is a matter of perspective." (Image above: A total solar eclipse in Australia. NASA.)
Meanwhile, WIRED did the math to try and figure out how many people could actually watch the total solar eclipse in August. I won't spoil the amount - you'll just have to click and find out yourself!
A New Gold Rush In California
There's gold in the rivers! Well, some rivers... and it's all due to that Oroville Dam that was damaged back in February due to heavy rain. LiveScience has more: "The Oroville Spillway emergency in California may have one silver — or gold — lining: The debris kicked up by weeks of heavy rain and runoff is now flecked with gold, and amateur gold panners are enjoying quite the bonanza. The "gold rush" is occurring along the Feather and Yuba rivers, which are fed by the Oroville Dam. Of course, would-be panners should take note: It's unlikely that panners will hit the jackpot and retire with steamer trunks full of gold bars; the average haul from panning the river lately is worth just $40 to $300, CBS5 reported."
Tectonic Activity... And Life
You may not think of the two being connected, but a new theory out from scientists says that tectonic activity may actually be needed for life to exist. More from Scientific American: "Our planet is in constant flux. Tectonic plates—the large slabs of rock that divide Earth’s crust so that it looks like a cracked eggshell—jostle about in fits and starts that continuously reshape our planet—and possibly foster life. These plates ram into one another, building mountains. They slide apart, giving birth to new oceans that can grow for hundreds of millions of years. They skim past one another, triggering earth-shattering quakes. And they slip under one another in a process called subduction, sliding deep into the planet’s innards and producing volcanoes that spew gases into the atmosphere. And not only is Earth alive, it is a vessel for life. Because it is the only known planet to host both plate tectonics—that ongoing shuffling of tectonic plates—and life, many scientists think the two might be related. In fact, some researchers argue that shifting plates, which have the ability to help regulate a planet’s temperature over billions of years, are a crucial ingredient for life."
