"Aid begins to flow to Puerto Rico, facing a growing humanitarian crisis in Maria's aftermath"
"Large amounts of federal aid began moving into Puerto Rico on Saturday, welcomed by local officials who praised the Trump administration's response but called for the emergency loosening of rules long blamed for condemning the U.S. territory to second-class status. In northwest Puerto Rico, people began returning to their homes after a spillway eased pressure on a dam that cracked after more than a foot of rain fell in the wake of the hurricane. The opening of the island's main port in the capital allowed 11 ships to bring in 1.6 million gallons of water, 23,000 cots, dozens of generators and food. Dozens more shipments are expected in upcoming days. The federal aid effort is racing to stem a growing humanitarian crisis in towns left without fresh water, fuel, electricity or phone service. Officials with the Federal Emergency Management Agency, which is in charge of the relief effort, said they would take satellite phones to all of Puerto Rico's towns and cities, more than half of which were cut off following Maria's devastating crossing of Puerto Rico on Wednesday."

Tracking MARIA

We're still tracking MARIA in the Atlantic basin and according to NOAA's NHC, it was a category 2 storm with sustained winds of 105mph as of midday Sunday.

Tracking MARIA

Here's the official track from NOAA's NHC, which show the storm generally lifting north-northeast through the week ahead, but note the "cone of uncertainty" fanning out over the next several days. This means that there is still some uncertainty on where MARIA will actually track and could actually be a little closer to the East Coast, which would mean bigger impacts in those areas. With that said, tropical storm watches have been issued for areas in yellow along the eastern part of North Carolina. The good news is that the worst of the wind, rain and high surf will stay offshore.

 Tracking MARIA - GFS (American Model)
Here's the GFS (American Model) of MARIA as it nears the East Coast through the first half of the week. This particular model keeps the center of the storm offshore, but we will likely still have big impacts across the region and especially along the coast. Keep in mind that it is still too early to tell exactly where the storm will track, it will be important to keep an eye on weather forecasts over the next few days. The good news is that we are seeing a trend in a majority of the models, which keep the worst offshore.
Tracking MARIA - ECMWF (European Model)
Just for comparison, here is the ECMWF model, which shows the placement of the storm at 7pm Wednesday. While the center of the storm looks to stay offshore, we will likely still have strong winds, high surf and potentially heavy rains along the coast. Again, it's too early to tell where the storm will track exactly, but folks in these areas need to pay attention to weather forecast over the days ahead. 
Tracking MARIA - Strongest Wind Gusts PM Wednesday
Here's a quick look at what kind of wind gusts we could be dealing with by 7PM Wednesday. Note that some spots along the coast could be seeing up to 50 to near 60mph+ wind gusts, while widespread tropical storm force (39mph+) wind gusts could be possible for a number of inland locations from South Carolina to North Carolina and Virginia. The other image below suggests when tropical storm force winds could arrive. Note that those in the eastern portions of the Carolinas could see tropical storm force winds arriving by Monday afternoon/evening.
Tracking MARIA - How Much Rain?
Here's the rainfall potential through Thursday, which suggests fairly heavy rain in far eastern North Carolina. Note that some locations in the Outer Banks could see up to 2" to 4"+ rainfall. Again, keep in mind that the rain fall potential will be heavily dictated by the track of the storm. If the storm tracks farther west and closer to the coast, we can expect heavy rain & wind across a much wider area, but if the storm shifts east, we can expect less rain and not as strong of winds. Stay tuned...

Atlantic Outlook Next 5 Days
Here's the Atlantic outlook over the next few days, which shows that the basin remains very active as we head into the 4th week of September. While LEE has once again redeveloped, it should cause any issues close to home, but we'll continue watching MARIA as it lifts north over the coming days.
Tracking LEE 
Here's a look at LEE on visible satellite from midday Sunday, which showed an impressive category 1 storm with sustained winds of 90mph. Remember LEE developed last week and fell apart, but the remnants were able to mature into a hurricane once again. 
Tracking LEE
Here's NOAA's NHC forecast for LEE, which at this point doesn't appear to be all that impressive as it tracks northwest over open water into early next week. Stay tuned...
Active in the Eastern Pacific
While things remain active in the Atlantic Basin, things in the Eastern Pacific are still somewhat active. According to NOAA's NHC, Tropical Storm PILAR has formed and there is also another wave of energy that has a MEDIUM chance of tropical formation over the next 5 days.
Tracking PILAR
As of midday Sunday, PILAR was a tropical storm with sustained winds of 40mph. It doesn't look like much, but gusty winds and heavy rains will be likely along the west coast of Mexico over the next coming days.
Tracking PILAR
Here's the official track of PILAR, which doesn't show much further development. However, due to the fact that it will be so close to the Mexican coast, heavy rains and gusty winds will likely continue through the early week time frame. 

September 10th - Official Peak of the Atlantic Hurricane Season
It's only fitting that on the official peak of the Atlantic Hurricane Season (September 10th), Hurricane IRMA made landfall with the Lower Florida Keys at 9:10am on Sunday, September 10th. Note that the season, on average, remains pretty active through the rest of September and throughout October, but falls dramatically into November. Keep in mind that the official end of the Atlantic Hurricane Season is November 30th.
PRELIMINARY 2017 Tornado Map

It certainly has been a fairly active first half of 2017 with 1373 preliminary tornado reports through September 22nd. Note that this is the most tornadoes through September 23rd since 2011, when there were 1,784 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 1373 (through September 22nd). Note that is the most active year for tornadoes since 2011, when there were 1,784 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.) Heavy rain across portions of the Central Plains and Southern Plains, Mon, Sep 25.
2.) Heavy rain across portions of the Southern Plains, Tue-Fri, Sep 26-Sep 29.
3.) High significant wave heights for coastal portions of the Mid-Atlantic and the Northeast, Wed, Sep 27.
4.) Heavy rain across portions of the Alaska Panhandle, Tue-Wed, Sep 26-Sep 27.
5.) Much above normal temperatures across portions of the Northeast, the Central Appalachians, the Mid-Atlantic, the Upper Mississippi Valley, the Great Lakes, and the Ohio Valley, Tue-Wed, Sep 26-Sep 27.
6.) Flooding occurring or imminent across portions of the Southeast.
7.) Severe Drought across the Central Plains, the Northern Plains, Hawaii, the Northern Rockies, the Middle Mississippi Valley, California, the Upper Mississippi Valley, and the Southern Plains.


"Rain and snow take aim at the Montana drought"

"The weather this summer has been downright unruly, but it's ready to make amends. After months of extreme drought and fire, the state is getting some much-needed rain and snow. "We ended up receiving a second round of precipitation, mainly in southwest and central Montana," Jim Brusda, lead meteorologist with the National Weather Service, said. "It's pretty welcome because of how dry it has been." Lewistown is reaping the most benefits from the weather system with .32 inches by Friday afternoon. The east side of the Big Snowies has already received nine inches of snow. The rainfall wasn't too excessive in Great Falls, where only .18 inches fell, while, approximately .14 inches fell in Helena by Friday afternoon. Other places were worse off, with just a trace, .01 inches, in Cut Bank and nothing in Havre. But every drop of rain is going to good use. Brusda said the soil is absorbing all of the precipitation."

Latest Drought Monitor

Here's the latest drought update from the US Drought Monitor, which shows EXCEPTIONAL drought conditions continuing across parts of Montana. Note that nearly 99% of the state is considered to be abnormally dry, but the EXCEPTIONAL drought covers nearly 18% of the state, which is down from nearly 26% last week. In North Dakota, less than 1% is in an EXCEPTIONAL drought, but nearly 3% of the state is still in an EXTREME drought, which is also down from the near 19% last week.

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 weeks/months 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!


Chetco Bar Fire - 5 Miles Northeast of Brookings, OR

The Chetco Bar Fire near Brookings, Oregon is a very large wildfire in the Western US that started on Wednesday,  July 12th by lightning and has grown to more than 191,000 acres! There are nearly 1,200 people working on this fire, which is 97% contained. The estimated containment date is set for Sunday, October 15th.

"Incident Summary: In the past week firefighters have made good progress in containing and strengthening lines around the Chetco Bar Fire. Firefighters, including crews with Oregon Army National Guard Task Force 5, continue to monitor and patrol the fireline, adding waterbars and recovering equipment where where containment objectives have been achieved. The current weather pattern is more favorable for firefighters and the area forecast includes more than an inch of rain in addition to cooler temperatures and higher humidity over the next few days. Evacuations and Closures: All Evacuation Advisories in Curry County and Josephine County have been lifted."

Diamond Creek Fire - Mazama, Washington

The Diamond Creek Fire near Mazama, Washington is a very large wildfire in the Western US that started on Sunday,  July 23rd and has grown to more than 127,000 acres! There are nearly 202 people working on this fire, which is 77% contained. The estimated containment date is set for Sunday, October 15th.

"Incident Summary: The Diamond Creek Fire was reported on July 23, 2017 at approximately 9:45 a.m. The fire is burning in the Pasayten Wilderness and Eightmile drainage about 11 miles north of Mazama, Washington. Smokejumpers responded to the fire within two hours of it being reported. However, due to extreme terrain, heavy dead and down timber, and critical fire weather conditions, the fire was unable to be contained during initial response. The fire crossed into Canada on August 29. Fire managers recognized that the Diamond Creek Fire would likely be a long term event. Monitor, confine and point protection strategies are being used inside the Pasayten Wilderness. Outside the wilderness, the fire is being managed under a suppression strategy using a mixture of direct, indirect and point protection tactics when and where there is a high probability of success. Fire personnel will engage the fire at the appropriate time and location, while keeping public and firefighter safety as the top priority. Fire personnel are currently focused on identifying and implementing suppression repair work on the primary and contingency control lines. The suppression repair will not compromise the intended purpose of the control lines should they be needed at a later date"

Ongoing Large Wildfires

Here's a look at the current wildfire map across the country. Continued hot and dry weather has helped to spark several wildfires across the Western US. There have even been fires popping up in the Eastern U.S., two of the larger fires are burning in Florida.

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


National Weather Outlook

Here's the weather outlook through the early part of the week, which shows a cool front stalling across the central part of the country. This will keep the threat of scattered showers and storms in place with areas of locally heavy rain. Also note MARIA, the tropical system in the Atlantic approaching the East Coast as we head into the early week time frame. This will bring heavy rain, wind and storm surge to places there.

5 Day Precipitation Outlook

According to NOAA's WPC, the next several days could produce very heavy rainfall across the Plains with some 4" to 8" amounts possible, especially across parts of western Texas. Also note the heavy rain potential just clipping the East Coast, which would be associated with MARIA. 

Snowfall Potential
Snowfall will likely continue in the mountains as we head into the early week time frame, but should begin to taper as the storm winds down. Snow totals could end up being upwards of 12" or more by the time it finally ends.
Snowy Western US
Here's a view from Park City Mountain, which shows snow flying from Sunday. The recent colder than average weather and Pacific moisture brought quite a bit of white stuff to the mountains of the Western US.
A Sloppy Monday - Free A/C Kicks In This Week
By Paul Douglas
90F in late September? Impressive, when you consider the sun was as high in the sky yesterday as it was back on March 18. Consider it a bonus summer weekend; one more chance to exercise your sweat glands before aerobic shivering season sets in. It confirms a suspicion I've had for some time: summer warmth in Minnesota (balmy enough to swim in our lakes) lasts the better part of 4 months now.
You may need more clothing this week as Canadian air returns, with daytime highs mostly in the 60s; jacket-worthy mornings dipping into the 40s. Autumn elbowing its way into summer warmth & humidity squeezes out half an inch of rain from showers and T-storms into Tuesday morning. The maps look like fall, but I have little doubt we'll see more 70s, even a few more 80s in October.
In the meantime Hurricane Maria brushes North Carolina's Outer Banks with high winds & surf into midweek. Sadly, Puerto Rico is now Exhibit A for the horrors that result when the grid goes down for an extended time. Consider donating to fellow Americans at redcross.org or by calling The Red Cross at 1-800-435-7669.
Extended Forecast
MONDAY: Showers and T-storms. Winds: NW 5-10. High: 68.
MONDAY NIGHT: Scattered showers, rumbles possible. Winds: N 5. Low: 58.

Weather Outlook For Monday

Temperatures on Monday will be quite a bit cooler than it was this weekend as the front slowly shitfs east. Highs in the Twin Cities will be nearly 20F cooler than it was Friday-Sunday as highs slip into the 60s. Note that along the front, temperatures will be closer to average, while temp east and west of the front will be quite a bit warmer and cooler than average. 

Weather Outlook For Sunday
Winds will shift more northerly as the front shift east of the Twin Cities. This will help to bring much cooler than average temperatures to the region over the next several days.

Weather Outlook For Monday

A stalled frontal boundary will continue to slowly shift east with areas of scattered showers and storms, which will likely stick around through the first half of Tuesday.
Simulated Radar Ahead...
Here's the simulated radar across the Upper Midwest as we head through early next week. The stalled front will slowly move east through the early week time period, which will help to bring areas of storms and heavy rain to parts of the region.
Rainfall Potential Ahead
Here's the rainfall potential across the state as we head through AM Friday. Note that many areas from southwestern to northeastern Minnesota could stay quite wet with some widespread 1" to 2"+ tallies.


Minnesota Drought Conditions

According to the US Drought Monitor, only 0.05% of the state is considered to be in a SEVERE drought, which dropped from the near 2% last week. Also note that nearly 16% of the state is considered to be in a MODERATE drought, which is also down from the near 21% from last week.


Minneapolis Temperature Outlook

Here's the temperature outlook through October 9th, which shows temps cooling significantly from the summerlike weekend we just had. Readings will be more Fall-like as we dip into the 60s and 70s through the early part of October.

6 to 14 Day Temperature Outlook

According to NOAA's CPC, the extended temperature outlook from October 2nd through the 6th suggests warmer than average temperatures possible across parts of the Midwest.


Extended Temperature Outlook

According to NOAA's CPC, the extended temperature outlook through October 8th shows that a good chunk of the Southern U.S. will be cooler than average, but the Western and Northern US will remain warmer than average.


Fall Color - Coming To A Tree Near You...

It's about that time of the year again to gaze upon Mother Nature's fall foliage, which is really starting to show up. By now, you've probably noticed a few eager trees changing color pretty rapidly, some of this could be due to a little stress, but it's not uncommon to start seeing some changes at this time of the year.

Minnesota Fall Color Update

According the MN DNR, much of the state is already starting to see hints of fall color, however, there are pockets of 50%-75% color across northern Minnesota!

Follow along as the fall colors change with the MN DNR map HERE:

Typical Fall Color Peak in Minnesota

Here are the typical fall color peak times across the state of Minnesota and note that areas along the northern tier of the state usually see their peak toward the 2nd half of September. However, peak color usually doesn't arrive in central Minnesota until October, but we're getting close.

Typical Fall Color Times Across the Country

Here are the typical fall color peak times across the country, which suggests that much of the peak across the northern half of the nation usually wraps up through the month of October.

"A hole in the sun's atmosphere is spewing solar wind toward Earth. This image from NASA's Solar Dynamics Observatory shows where solar magnetic fields have parted, allowing the gaseous material to escape. Traveling faster than 600 km/s (1.3 million mph), the solar wind is expected to reach our planet on Sept. 24th, bringing a 40% chance of polar geomagnetic storms according to NOAA forecasters. The chance of storms rises to 50% on the next day, Sept. 25th, as Earth moves deeper into the stream. Northern sky watchers should be alert for autumn auroras."
Northern Lights Forecast for Sunday, September 24th
"Forecast: Auroral activity will be high. Weather permitting, highly active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Iqaluit to Juneau, Edmonton, Winnipeg, Thunder Bay and Sept-Iles, and visible low on the horizon from Seattle, Des Moines, Chicago, Cleveland, Boston, and Halifax."
"Irma may speed the end of orange juice"

"The most recent estimates of the widespread damage to Florida’s orange trees put the statewide losses as high as 70 percent. Hurricane Irma plundered Florida’s orange belt, leaving a trail of uprooted trees, downed fruit and flooded groves worse than anything growers say they have seen in more than 20 years. It could even be the knock-out blow for a product — orange juice — that has been slipping in popularity among Americans, although the beverage still ranks as the country’s favorite fruit. The most recent estimates of the widespread damage to Florida’s orange trees put the statewide losses as high as 70 percent. That could lead to orange shortages, price hikes and, for farmers, lost harvests — all on top of a debilitating plant disease called citrus greening and a long-term national decline in orange juice consumption. “Significant is not the right word,”said Shannon Shepp, the executive director of the growers’ group Florida Department of Citrus, describing the damage to Florida’s orange juice industry. “It’s somewhere between significant and catastrophic. And that’s a big word — I don’t use it lightly.” It could have implications not only for Florida agriculture, but for the American diet."

"California cities want Big Oil to pay for costs of climate change"

"Coastal cities in California that are vulnerable to flooding caused by climate change are fighting back against Big Oil. San Francisco and Oakland filed lawsuits this week demanding that ExxonMobil, Chevron (CVX), BP, ConocoPhillips (COP) and Royal Dutch Shell pay billions to cover the costs of sea walls and other protections against rising sea levels. The aggressive strategy from the Bay Area makes San Francisco and Oakland the first major U.S. cities to attempt to shift the costs of climate change from the public to fossil fuel companies. San Francisco and Oakland fear that billions of dollars of property in low-lying areas will be swamped by rising sea levels that scientists blame on climate change. "These fossil fuel companies profited handsomely for decades while knowing they were putting the fate of our cities at risk," San Francisco City Attorney Dennis Herrera said in a statement announcing the lawsuits, which were filed in Superior Court in San Francisco and Alameda Counties."

"One of the most bizarre ideas about climate change just found more evidence in its favor"

"More and more, we are learning that climate change can lead to some pretty strange and counterintuitive effects, especially when it comes to the wintertime. For instance, scientists have pointed out for a number of years that warmer seas, and a wetter atmosphere, can actually fuel more snowfall in massive nor’easters affecting the U.S. East Coast. More controversial still is an idea called “Warm Arctic, Cold Continents.” This is the notion that as the Arctic warms up faster than the middle latitudes, it may sometimes cause a displacement of the region’s still quite frigid air to places that aren’t so used to it. In other words, even as the planet warms, masses of cold air could also become more mobile and deliver quite a shock at times when outbreaks occur in more southerly latitudes."

"NASA’S OSIRIS-REx Spacecraft Slingshots Past Earth"

"NASA’s asteroid sample return spacecraft successfully used Earth’s gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August. At 12:52 p.m. EDT on Sept. 22, the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) spacecraft came within 10,711 miles (17,237 km) of Antarctica, just south of Cape Horn, Chile, before following a route north over the Pacific Ocean. OSIRIS-REx launched from Cape Canaveral Air Force Station in Florida on Sept. 8, 2016, on an Atlas V 411 rocket. Although the rocket provided the spacecraft with the all the momentum required to propel it forward to Bennu, OSIRIS-REx needed an extra boost from the Earth’s gravity to change its orbital plane. Bennu’s orbit around the Sun is tilted six degrees from Earth’s orbit, and this maneuver changed the spacecraft’s direction to put it on the path toward Bennu. As a result of the flyby, the velocity change to the spacecraft was 8,451 miles per hour (3.778 kilometers per second)."

See more from NASA Here:

(OSIRIS-REx is NASA's mission to explore near-earth asteroid Bennu, collect a sample, and return it to Earth. To get to Bennu, however, OSIRIS-REx must first leave the plane of Earth's orbit and match the orbital tilt of its target. On September 22, 2017, OSIRIS-REx approached Earth and flew over its southern hemisphere, passing within 11,000 miles of Antarctica. Credits: NASA's Goddard Space Flight Center)
