Sloppy snow Tuesday night? Winter Storm Watch posted for Twin Cities

What Did You Eat?

My niece, Anna Ball, just got back from an extended stay in Italy. She told me locals don't greet each other with "How are you?" They ask "What did you eat?" Life revolves around food. Can't remember?

"If you can't remember what you ate it must not have been very good" Anna told me.

I'm lobbying St. Paul to replace "What do you think of this weather?" OK, don't hold your breath.

What may be our first accumulating snow event of the winter season may materialize from a sloppy southern storm; a cold rain Tuesday afternoon changing to wet snow Tuesday night.

Ground temperatures are still fairly mild, so I expect some melting on contact, but a few inches could pile up on metro lawns; roads becoming slushy and slick after 7 PM. The ECMWF (European) model prints out 6+ inches for southwest counties.

And so it begins.

This is just Old Man Winter firing a warning shot across our bow. After a couple days in the 30s midweek we thaw into the 40s; I could see a few days above 50F next week. No sign of anything frigid just yet.

A puff of cooler air sparks a few rain showers today. Within 36 hours there will be no doubt in your mind that it's November.

What DID I eat? I'd rather focus on food.


Winter Storm Watch Posted. Map courtesy of Ham Weather. The Twin Cities office of the NWS has issued a Winter Storm Watch, which means a potential for "plowable" amounts of snow, coming Tuesday night. Details:

...WINTER STORM WATCH IN EFFECT FROM TUESDAY AFTERNOON THROUGH
LATE TUESDAY NIGHT...

THE NATIONAL WEATHER SERVICE IN TWIN CITIES/CHANHASSEN HAS ISSUED
A WINTER STORM WATCH...WHICH IS IN EFFECT FROM TUESDAY AFTERNOON
THROUGH LATE TUESDAY NIGHT.

* SNOW ACCUMULATION: 4 TO 7 INCHES...WITH HIGHER AMOUNTS POSSIBLE.

* TIMING: RAIN WILL OVERSPREAD THE AREA FROM THE SOUTH TUESDAY
  AFTERNOON WITH A TRANSITION TO SNOW OCCURRING LATE TUESDAY
  AFTERNOON OR EVENING. THE SNOW WILL TAPER OFF LATE TUESDAY NIGHT
  OR EARLY WEDNESDAY MORNING.

* IMPACTS: THE FIRST HEAVY SNOW OF THE SEASON IS POSSIBLE NEAR THE
  TUESDAY AFTERNOON AND WEDNESDAY MORNING COMMUTES. IN
  ADDITION...IT IS LIKELY TO BE A WET SNOW AND ANY TREES WITH
  LEAVES LEFT ON THEM MAY BE STRESSED...LEADING TO BROKEN TREE
  LIMBS AND ISOLATED POWER OUTAGES.

Probability Of 4"+ Snow. The best chance of plowable snows will come over southwestern Minnesota, a 50-60% probability of 4" or more, based on NOAA guidance, compared to a 20-30% risk over the Twin Cities.


NAM Solution. I'm not buying this solution (yet). I want to see a few more runs before I start attaching inch amounts to any Twin Cities forecast, but the greatest potential for enough snow to shovel and plow (?) will probably come south of the Twin Cities. Map above: NOAA.


Chilly Week - Some Moderation Next Week. ECMWF guidance keeps highs in the 30s Wednesday and Thursday; highs near 40F over the weekend, then well into the 40s a week from now. Precipitation tomorrow starts as rain, with a probable changeoever to wet snow Tuesday night. A light rain-snow shower mix is possible late Friday into Saturday with little or no accumulation. Graph: Weatherspark.


Winter Hazard Awareness Week In Minnesota. Map above shows average annual snowfall for Minnesota, courtesy of the Twin Cities NWS. Here's an excerpt of some good (timely?) information from the local National Weather Service office: "

During Winter Hazard Awareness Week the National Weather Service, in cooperation with the Department of Homeland Security and Emergency Management will issue daily statements pertaining to winter safety. These statements are available below, and will also be broadcast over NOAA All Hazards Weather Radio and sent over the NOAA Weather Wire.

In summary, we offer these basic reminders:

Winter Weather Preparations

  • Keep ahead of the winter storm by listening for the latest weather statements, watches and warnings.
  • Your vehicle should also be ready. Get it winterized, before the onset of winter weather.
  • Be equipped for the worst. Carry a winter survival kit in your car, especially when traveling in rural or open areas. Try to travel with others.

When Driving

  • Yield to snowplows, and give them plenty of room to operate.
  • If your vehicle becomes stranded, stay with it until help arrives.
  • Do not try to walk for help during a blizzard, you could easily become lost in the whiteout conditions.

Outdoor Activities

  • If you will be outside during storms or extreme cold, dress in layered clothing and avoid overexertion.
  • Do not kill yourself shoveling snow. Shoveling is very hard work and may induce a heart attack.
  • If you will be snowmobiling, avoid alcohol. Most snowmobile deaths are alcohol related. Take a snowmobile course offered by the DNR or check with your snowmobile dealer.
  • Every year, there are fatalities in Minnesota when people fall through thin ice.

Snowfall Last Winter. Nearly 68" of snow fell last winter, most of it during the latter half of winter (well into "spring"). The odds of this happening two winters in a row? Slim, but not zero. With any luck we won't be shoveling in May of 2014. Map above courtesy of the Twin Cities National Weather Service.


Hurricane Sandy One Year Later: 10 Places That Are Still Suffering. Rolling Stone has the update; here's an excerpt: "One year after Hurricane Sandy ravaged the Northeast coast, some of the hardest-hit communities continue to struggle with the storm's damage. Many of the areas most devastated by Sandy were home to low-income people who are now homeless. Even when families evicted by the storm have found somewhere safe to stay, they are frequently forced to bunk up with other families or sleep on the floor. Others hit the dunes. Making matters worse, winter is fast approaching. In New York City, families that were already vulnerable to the housing crisis now face incredible burdens to finding affordable shelter in their communities. "Sandy was extremely devastating, but it actually uncovered and brought to light an already existing problem, which was a lack of affordable housing," says Ismene Ispeliotis, executive director of the Mutual Housing Association of New York. "Now you have hundreds and thousands of additional families going into the shelter system and burdening available housing..." (Image: NASA).


Obama Signs Order On Response To Weather Disasters And Climate Change. Here's a clip from an article at The Washington Post: "A year after Hurricane Sandy devastated the East Coast, President Obama signed an executive order Friday to make it easier for states and local governments to respond to weather disasters. The executive order establishes a task force of state and local officials to advise the administration on how to respond to severe storms, wildfires, droughts and other possible effects of climate change. The task force includes governors of seven states — all Democrats — and the Republican governor of Guam, a U.S. territory. Fourteen mayors and two other local leaders also will serve on the task force. All but three are Democrats..."


Solar Activity Heads For Lowest Low In Four Centuries. No, it's not the sun heating things up (that's the first thing climate scientists analyzed). Here's an excerpt from New Scientist: "The sun's activity is in free fall, according to a leading space physicist. But don't expect a little ice age. "Solar activity is declining very fast at the moment," Mike Lockwood, professor of space environmental physics at Reading University, UK, told New Scientist. "We estimate faster than at any time in the last 9300 years." Lockwood and his colleagues are reassessing the chances of this decline continuing over decades to become the first "grand solar minimum" for four centuries. During a grand minimum the normal 11-year solar cycle is suppressed and the sun has virtually no sunspots for several decades. This summer should have seen a peak in the number of sunspots, but it didn't happen..." (Image: NASA).


America's Most Violent Tornadoes Since 1950, Seen On One Blustery Map. Here's a clip from a fascinating article at The Atlantic Cities: "...The interactive visualization, available here for your geeking-out pleasure, was assembled by New York City technoartist Adam Pearce, who also did that wonderful presentation of 500 years of meteor spottings. Inspired by a similar model made by John Nelson, Pearce whipped up a map that gives the track and wind intensity for each of the twisters. While meteorologists have noted more than 21,000 tornadoes in the past 63 years, only long-lasting ones that traveled for more than 20 miles are shown here (just under 2,000). Fatter lines represent more powerful ones, and the tracks are approximate, as NOAA "only collects start and end locations – tornadoes do not actually travel in perfectly straight lines," explains Pearce..."

Flood Insurance Is A Complex Problem That May Have A Simple Solution. Let the markets handle this vs. the federal government? Interesting idea, but what happens if a massive calamity wipes out a few of these private ventures? Here's a clip from a story at Insurance News Daily: "...There is a solution to the federal program’s problems that is beginning to gain attention, though it is somewhat unconventional. Some federal lawmakers argue that private insurers are capable of handling the risks associated with flood insurance coverage. Large insurance corporations certainly have the assets to offer coverage in an effective manner, but have little incentive to do so due to the potential of grievous loss. If the federal government could provide some degree of financial safety net for these companies, they may be willing to take on the risks associated with flood coverage, thereby alleviating some of the strain burdening the National Flood Insurance Program."


The U.S. Needs To Retire Daylight Savings And Just Have Two Time Zones - One Hour Apart. Quartz has the Op-Ed, here's the intro: "Daylight saving time ends Nov. 3, setting off an annual ritual where Americans (who don’t live in Arizona or Hawaii) and residents of 78 other countries including Canada (but not Saskatchewan), most of Europe, Australia and New Zealand turn their clocks back one hour. It’s a controversial practice that became popular in the 1970s with the intent of conserving energy. The fall time change feels particularly hard because we lose another hour of evening daylight, just as the days grow shorter. It also creates confusion because countries that observe daylight saving change their clocks on different days..."


America's First All-Electric School Bus Coming To California. EcoWatch has the story - here's a clip: "The first all-electric school bus could be picking up California students by 2014. Trans Tech Bus and Motiv Power Systems debuted the bus at the recent 2013 National Association for Pupil Transportation (NAPT) Annual Summit in Grand Rapids, MI. The two companies collaborated on the bus for the Kings Canyon Unified School District in the San Joaquin Valley of California. “An electric bus can save a school district about 16 gallons of fuel a day, or around $11,000 in fuel savings over a year, not to mention maintenance savings,” Trans Tech President John Phraner said..."

Man Drives Across U.S. In Under 29 Hours. My new hero. But wouldn't it have been easier to fly? Maybe not, come to think of it. CNN has the details on Cannonball II, a new U.S. record which may stand for a good, long while. Here's an excerpt: "...Beginning in 2009, about the time he started working for Lamborghini Atlanta, Bolian researched cars, routes, moon phases, traffic patterns, equipment, gas mileage and modifications. He went into preparation mode about 18 months ago and chose a Mercedes CL55 AMG with 115,000 miles for the journey. The Benz's gas tank was only 23 gallons, so he added two 22-gallon tanks in the trunk, upping his range to about 800 miles. The spare tire had to go in the backseat with his spotter, Dan Huang, a student at Georgia Tech, Bolian's alma mater. To foil the police, he installed a switch to kill the rear lights and bought two laser jammers and three radar detectors. He commissioned a radar jammer, but it wasn't finished in time for the trek..."

Photo credit above: "Dave Black, Ed Bolian and Dan Huang pose in front of the car they would use to attempt to break the record. Bolian is the leader and main driver, Black acted as the co-driver and Huang was the team's spotter - keeping an eye on the car's considerable technology while looking out for obstacles."


55 F. high in the Twin Cities Sunday.

49 F. average high on November 3.

November 3 in Minnesota Weather History - courtesy of the Twin Cities National Weather Service:

1982: 20 inches of snow falls in the Kabatogema area.

1901: With a high temperature of only 22 and a low of 15, 175 boxcars of potatoes were in peril at the Minneapolis rail yard. Workers scrambled to move the rail cars full of tubers in roundhouses and transfer potatoes to refrigerated cars. Individual stoves had to be purchased on the spot for 59 remaining cars. Thankfully, most of the spuds were saved.

1853: Cold snap begins at Ft. Snelling. The next four days would be 16 degrees or lower.

1727: The first outdoor celebration at the chapel of Fort Beauharnois on Lake Pepin was postponed due to "variableness of the weather."


TODAY: Mostly cloudy, few showers. Winds: SW 10-20. High: near 50

MONDAY NIGHT: Partial clearing, turning cooler. Low: 33

TUESDAY: Mostly cloudy with rain developing; changing to wet snow during the afternoon. Mainly wet roads. High: 43 (falling during the day)

Climate Stories....

"First they ignore you, then they laugh at you, then they fight you, then you win."

Climate Change Seen Posing Risk To Food Supplies. Here's an excerpt of a Justin Gillis article at The New York Times: "...In a departure from an earlier assessment, the scientists concluded that rising temperatures will have some beneficial effects on crops in some places, but that globally they will make it harder for crops to thrive — perhaps reducing production over all by as much as 2 percent each decade for the rest of this century, compared with what it would be without climate change. And, the scientists say, they are already seeing the harmful effects in some regions..."


Experts Say Nuclear Power Needed To Slow Warming. The reason? Renewables are scaling up rapidly, but may not be able to provide enough energy fast enough to meet global (low-carbon) needs. Here's a snippet of a story from AP at KOTA News: "Some of the world's top climate scientists say wind and solar energy won't be enough to head off extreme global warming, and they're asking environmentalists to support the development of safer nuclear power as one way to cut fossil fuel pollution. Four scientists who have played a key role in alerting the public to the dangers of climate change sent letters Sunday to leading environmental groups and politicians around the world. The letter, an advance copy of which was given to The Associated Press, urges a crucial discussion on the role of nuclear power in fighting climate change...."


Do The Math: Fossil Fuel Investments Add Up To Climate Chaos. Here's an excerpt from an entry at Huffington Post: "...Now more than ever people need to demand that all financial institutions that we have entrusted with our money and welfare remove their money -- our money -- from investments in the fossil fuel industry. Make no mistake we are in a battle for the future with the past. The centuries-old fossil fuel industries have roots deep within our governments and other institutions. They know their days are numbered, they know their power is waning, but they will not go silently into the night. they will not give up their power without a fight. If governments will not bite the hand that feeds, if they will not free themselves from corporate sponsorship then we, the citizens, the concerned and morally driven individuals will have to take a stand. We will have to make sacrifices to challenge the deadly status quo. This is what history teaches us..."


Study: Storms Would Submerge Norfolk Naval Station. The Navy is paying attention to rising sea levels, worldwide, as reported in this story at PilotOnline.com; here's an excerpt: "...Average global temperatures have risen 2 degrees since the mid- to late 1800s, and sea levels have climbed a foot. With melting glaciers and ice sheets, the trend could speed up. In 2009, Titley compiled data for the Navy on what climate change means for the service. He was pleasantly surprised, he said, by how receptive the leadership was. Still, with costs that likely will climb into the trillions, the challenges of meeting the threat are formidable. Even if the Navy does little now, it can use the study findings to plan what needs to be done, said Titley, who retired from the Navy 13 months ago. "What is our backup if you lose Norfolk?" he asked. "What's plan B?...."

New Finding Shows That Climate Change Can Happen In A Geological Instant. This story at phys.org made me do a double-take. Remember, we don't know what we don't know. It's the "unknown unknowns" that worry climate scientists the most. Tipping points? Sudden swings into a new climate state? At the rate CO2 is building up in the atmosphere anything is possible in the years ahead. Here's an excerpt: "Rapid" and "instantaneous" are words geologists don't use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago. In a new paper in the Proceedings of the National Academy of Sciences, Morgan Schaller and James Wright contend that a doubling in carbon dioxide levels, the surface of the ocean turned acideic in over a period of weeks or months and global temperatures rose by 5 degrees centigrade - all in the space of about 13 years. Scientists previously thought this process happened over 10,000 years..."

Last Time Arctic Was This Warm Was 120,000 Years Ago. Here's a headline that got my attention. Andrew Freedman has the story at Climate Central: here's an excerpt: "Average summer temperatures in the Eastern Canadian Arctic during the past 100 years are hotter than they have been in at least 44,000 years, and possibly as long as 120,000 years, according to a new study. The study of mosses emerging from beneath receding glaciers on Baffin Island — the world’s fifth-largest island located west of Greenland — confirms that rapid Arctic warming has already put parts of the region in new climatic territory. Arctic warming is transforming the Far North by melting sea and land ice, speeding spring snowmelt, and acidifying the Arctic Ocean. Arctic warming may even be redirecting the jet stream in the northern midlatitudes, making some types of extreme weather events more likely in the U.S. and Europe..."

Pacific Ocean Warming At Fastest Rate In 10,000 Years. Here's a clip from Penn State climate scientist Michael Mann at Huffington Post: "Just how rapid is the current rate of warming of the ocean? There is an interesting new article by Rosenthal and collaborators in the latest issue of the journal Science entitled "Pacific Ocean Heat Content During the Past 10,000 Years" that attempts to address this question. The article compares current rates of ocean warming with long-term paleoclimatic evidence from ocean sediments. So how rapid is the ocean warming? Well, for the Pacific ocean at least, faster than any other time in at least the past 10,000 years. The study finds, specifically, that (to quote Columbia University's press release) the "middle depths [of the Pacific Ocean] have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000..."


Study: Northern Hemisphere Summers Now Warmest Of Last 600 Years. Rawstory.com has the article; here's the intro: "Summers in the northern hemisphere are now warmer than at any period in six centuries, according to climate research published on Wednesday in the science journal Nature. Harvard University researchers analysing evidence from Arctic tree rings, ice cores, lake sediments and thermometer records said recent warm temperature extremes in high northern latitudes “are unprecedented in the past 600 years” both for magnitude and frequency. “The summers of 2005, 2007, 2010 and 2011 were warmer than those of all prior years back to 1400,” they reported..."


Pacific Ocean Warming 15 Times Faster Than Before. USA Today has the story; here's the introduction: "Although the temperature of the Earth's atmosphere may have hit the "pause" button recently — with little global warming measured over the past few years — that hasn't been the case with the oceans. In a study out today in the journal Science, researchers say that the middle depths of a part of the Pacific Ocean have warmed 15 times faster in the past 60 years than they did during the previous 10,000 years..."
