Meteorological "May"-hem. Historic Snows Thursday to 70F Next Week (why is this happening?)

Posted by: Paul Douglas Updated: May 2, 2013 - 11:34 PM

18" snow at Blooming Prairie, Minnesota yesterday

81 F. high reported in the Twin Cities on May 2, 2012.

Tulsa, Oklahoma saw a trace of snow yesterday - the latest snow on record.

 

 

Jaw-dropping Extremes

 

Just when you thought you'd seen everything, along comes the Backwards Spring of 2013. 18" at Blooming Prairie, Minnesota. On May 2. The Twin Cities dodged a bullet, but this event will probably be the snowiest May snowstorm on record for Minnesota, Wisconsin and Iowa.

Every morning I dial up the latest maps, afraid what I may find next. Parts of California are on fire, while a rare May freeze pushes into Texas; record floods washing out roads in Key West. Many Midwestern counties went from drought to flood in less than 2 weeks. Head-snapping weather.

In spite of La Nina, 2012 was the 9th warmest year, worldwide, on record. Record melting of Arctic ice last year may be impacting the jet stream, the river of high-speed air sweeping the globe - increasing the chance of blocking patterns, which can cause weather to temporarily stall. The result? A high amplitude pattern - more north/south swings in the jet stream capable of creating "cut-off" lows that can stall. Giant atmospheric roadblocks. More extremes.

The "stuck" storm over Missouri responsible for record snows east of MSP will rotate rain into town later today & Saturday. Expect 60F by Sunday; some 70s next week as spring returns. Fishing Opener? A rather mild Saturday gives way to a cooler front by Mother's Day; probably dry for Race For The Cure.

Better days ahead. It can only get better right?

Tree-Snapping Snows. HIgh water content (1 to 1.5" liquid) created a very heavy, wet snow just east of the Twin Cities. Heart-attack snow.

A Very Close Call. Waking up to a pale-green lawn Thursday morning was annoying (having predicting a coating to 2" the night before), but I also felt pure relief. Can you imagine what a nightmare 12-18" of snow would have been for the immediate metro area yesterday? It was bad enough from Rochester to Owatonna and Red Wing,with downed trees and powerlines, hundreds of traffic accidents - all the result of concrete-like heavy, wet slush. 8" amounts were reported in Dakota County from Farmington to Cottage Grove, 4" at Lake Elmo. Here's an interactive map from NOAA.

 

Jaw-Dropping "May"-hem: Fire & Ice, Snow & Flooding. This pattern really is nothing short of remarkable; huge, sweeping north/south sweeps of jet stream energy capable of erasing a drought in a meteorological blink of an eye, or pulling an almost February-like airmass southward, with snowy consequences. Here's today's edition of WeatherNation TV's Climate Matters: "Is it really May 2nd? Some Midwest cities saw more than a foot and a half of snow. To the west super dry windy conditions are fueling wildfires and to the Southeast ongoing rains are leading to flooding. Meteorologist Paul Douglas has more on the May weather mayhem."

 

Ah, May In Iowa. Thanks to Iowa State for passing this one along, a comparison of May 2, 2012 with May 2, 2013. Go cyclones!

 

1.15" precipitation from this afternoon into Saturday evening (00z NAM).

Wet snow this afternoon should change to rain by this evening and tonight - little or no accumulation expected with wet roads.

70F highs likely next week, possible 80s within 2 weeks.

 

A Reason To Keep On Going. Today will feel like March 3, but by Monday of next week it will look and feel like spring again (and none of us will take warmth for granted ever again). The ECMWF shows a drier day Sunday, with dry weather spilling over into Monday and Tuesday; a few showers and T-storms possible Wednesday as highs top 70. We cool off a little late next week before warming into the 60s again on Saturday, probably the milder day of the Fishing Opener/Mother's Day weekend.
 
 
 
Encouraging Trends. The U.S. models are in fairly tight alignment, showing a warming trend into next week; a good chance of 70-degree highs by midweek.
 
 
Mother's Day Preview. Here is the 240 ECMWF forecast for next Sunday morning, May 12. It shows a cooler front pushing south; highs in the 50s (north) - maybe low 60s Twin Cities metro. It's early, but if this forecast verifies it would be dry and comfortably cool for Race For The Cure and brunch with your favorite mom. Don't forget about mom.
 
 
Risk Of A Real Warm Front. I'm not getting too excited just yet (we've been down this road before), but GFS numbers show a chance of 80s by mid-May. One thing is certain: we're going to have a cooler, wetter, stormier summer than last year.
 
 
Holding Pattern. We're seeing more of this - weather systems not only slowing down, but stalling for a few days, prolonging rain (and flooding) or making heatwaves and drought even more intense. A cut-off low over Missouri will pump more moisture into the Upper Midwest today and Saturday; the sun returns by Sunday. Flooding rains are possible from Florida into the Mid South and Mississippi Valley as the storm continues to stall, churning up Gulf moisture. NAM loop: NOAA>

 

What Is Going On? Bill Holton writes: "Paul, please explain to readers WHY this is happening? Snow of this magnitude has NEVER been seen in this part of the country in May, or anywhere in the U.S. outside of the Rockies." Bill, snow east of the Rockies, outside of higher terrain in New England, is exceedingly rare, yes - but not totally unprecedented. What we're seeing is consistent with what climate scientists have been predicting for 30 years. As northern latitudes warm the north-south temperature contrast weakens, which triggers a drop in jet stream winds - which become more unstable, with greater north/south swings, what meteorologists call a "high amplitude" pattern. When this happens warm, moist air can be transported unusually far north (helping to rapidly ease drought and trigger record flooding), while unusually cold air can sweep much farther south than usual, sometimes "cutting off" from the main belt of westerly steering winds, causing weather patterns to temporarily stall. In short, the weather has a greater potential to become become stuck.

Proving cause and effect is difficult, at times impossible, but talking with climate scientists there seems to be a strong causal connection between more weather extremes and record warming taking place in the Arctic. 90% of warming is going into the oceans, and some of that warmth is showing up in the Arctic, which has lost 70-75% of its ice volume in 50 years, reaching a record low in September, 2012. A warming Arctic can displace the cold air that should be at the top of the world farther south over Canada, Europe and Asia, setting the stage for more extremes, more head-scratching "Black Swan" weather events.

 

A blocking pattern (with a warm bubble of high pressure over Greenland) steered Superstorm Sandy into coastal New Jersey on October 29, 2012, which is highly unusual for late October. A blocking pattern resulted in blistering, record-setting heat over much of the USA last summer. Droughts and heatwaves can become even more intense, while (stalled) storms can squeeze out more rain, or snow. Keep in mind there's more water vapor in the air (a 4% increase in 40 years), more fuel for storms, summer and winter. Rain is falling harder during the summer months, and when it does snow, it tends to come down harder. There are few things more complicated and interconnected than weather and climate - more research is required, but it's probably safe to say that we'll see more extremes in the years ahead, more examples of weather on steroids.

Changes in the Arctic are happening much faster than predicted. Richard Alley at Penn State believes some of these changes are taking place 100 years ahead of schedule. Climate scientist James Hansen believes warming of the oceans and atmosphere is equivalent to 400,000 Hiroshima bombs going off every day. We may be undergoing a "phase transition" in the climate system, which is non-linear. Nature rarely moves in a straight line. Alarmist hype? I sure hope so. But the reality: we're in uncharted water when it comes to global changes and impact on local weather.

 

One Way To Break A Drought. The same extreme pattern responsible for the 3rd snowiest April on record is tugging Gulf moisture north. As of April 30 there is no more exceptional drought across the state of Minnesota. moderate drought has dropped from 98% to 15% of the state since April 2, which is amazing. Southwest Minnesota isn't entirely out of the woods, but if this pattern persists (likely) most of Minnesota will be drought-free by the end of May.

Huge California Brushfire Spreads Over 6,500 Acres. Here's an excerpt from Business Insider: "Authorities have ordered the evacuation of hundreds of homes due to a brush fire in California, Reuters reports. According to CBS Los Angeles, the brush fire has consumed around 6,500 acres of land along the U.S. 101 freeway near Camarillo and Newbury Park in Ventura County, suburban areas to the northwest of Los Angeles. The flames are being spread by high winds. ABC 10 News reports that more than 200 firefighters are tackling the blaze, with help from aircrafts dropping water and retardant. KTLA reports that the fire is "0% contained". There have been no reports of injuries so far..."

Low Tornado Numbers And Low Tornado Deaths: May 2012 - April 2013. Here's an excerpt from a NOAA blog post that caught my eye: "...The death toll from May 2012-April 2013 was 7. National Weather Service official statistics go back to January 1950, but we can extend that by using the work of Tom Grazulis from the Tornado Project, who has collected tornado fatality information back into the 17th century. The data are reasonably good back to 1875, but it’s still possible that there are some missed fatalities, particularly as we go back farther in time. So, where does 7 fatalities in 12 consecutive calendar months stack up? Again, here are the lowest totals, going back to 1875, for 12 consecutive months, with the starting month."

 

 

Allergies On The Rise In U.S. Kids, Government Study Finds. Here's an excerpt from NBC News: "Allergies triggered by food or the environment have risen sharply in U.S. children in recent years, especially among more affluent families, according to a large government study. The "epidemic" rise in allergies, as one expert describes it, is of concern because it increases the risk of potentially fatal respiratory diseases or disfiguring skin conditions that could require long-term care. The latest data, released on Thursday by the Centers for Disease Control, showed the prevalence of food allergies increased in children under age 18 from 3.4 percent in 1997 to 5.1 percent in 2011. Skin allergies rose from 7.4 percent to 12.5 percent in the same time period..."

 

Could You Go 1 Year Without The Internet? This Guy Did. Here's a fascinating tale from The Verge. Paul Miller went 365 days without logging onto the Internet. Was he better for it? Here's an excerpt of a very readable story: "I was wrong. One year ago I left the internet. I thought it was making me unproductive. I thought it lacked meaning. I thought it was "corrupting my soul." It's a been a year now since I "surfed the web" or "checked my email" or "liked" anything with a figurative rather than literal thumbs up. I've managed to stay disconnected, just like I planned. I'm internet free. And now I'm supposed to tell you how it solved all my problems. I'm supposed to be enlightened. I'm supposed to be more "real," now. More perfect. But instead it's 8PM and I just woke up. I slept all day, woke with eight voicemails on my phone from friends and coworkers. I went to my coffee shop to consume dinner, the Knicks game, my two newspapers, and a copy of The New Yorker. And now I'm watching Toy Story while I glance occasionally at the blinking cursor in this text document, willing it to write itself, willing it to generate the epiphanies my life has failed to produce. I didn't want to meet this Paul at the tail end of my yearlong journey..."

Climate Stories...

 

2012 Was The 9th Warmest Year, Worldwide, Since 1850. Here's an excerpt from a story at Huffington Post: "The World Meteorological Organization says last year was the ninth-warmest since record-keeping began in 1850, despite the cooling effect of the weather pattern called La Nina. The U.N.'s weather agency says this marks the 27th year in a row the global average temperature — 58 degrees Fahrenheit (14.45 degrees Celsius) in 2012 — surpassed the 1961-1990 average. WMO said in annual climate report Thursday the years from 2001 to 2012 were all among the top 13 warmest on record."

 

Most Americans Blame Global Warming For Extreme Weather. Climate change, "global weirding", call it what you want, but it's not your grandfather's weather pattern anymore, as reported in this story at LiveScience: "More than half of Americans think global warming is affecting weather in the United States, according to a new nationally representative survey that measures the pulse of American sentiment on climate change. The newly released study shows that about two out of three Americans say weather in the country has worsened over the past several years, with only one in 10 saying the weather has been improving. Americans also have strong views about the link between global warming and extreme weather..." (Photo: David Fine, FEMA).

 

Unburnable Fuel: Either Governments Are Not Serious About Climate Change Or Fossil Fuel Firms Are Overvalued. Here's an excerpt from a story at The Economist: "MARKETS can misprice risk, as investors in subprime mortgages discovered in 2008. Several recent reports suggest that markets are now overlooking the risk of “unburnable carbon”. The share prices of oil, gas and coal companies depend in part on their reserves. The more fossil fuels a firm has underground, the more valuable its shares. But what if some of those reserves can never be dug up and burned?..."

 

Belief In Biblical End Times Stifling Climate Change Action In The U.S. - Study. Eric Dolan at rawstory.com has the story; here's the intro: "The United States has failed to take action to mitigate climate change thanks in part to the large number of religious Americans who believe the world has a set expiration date. Research by David C. Barker of the University of Pittsburgh and David H. Bearce of the University of Colorado uncovered that belief in the biblical end-times was a motivating factor behind resistance to curbing climate change. “[T]he fact that such an overwhelming percentage of Republican citizens profess a belief in the Second Coming (76 percent in 2006, according to our sample) suggests that governmental attempts to curb greenhouse emissions would encounter stiff resistance even if every Democrat in the country wanted to curb them,” Barker and Bearce wrote in their study, which will be published in the June issue of Political Science Quarterly..."

 

Top Investors Will Feel Heat Of New Epoch. Here's an excerpt of an Eric Roston article at Bloomberg: "...Modeling climate economics is tricky, even more so than climate science is, if that's possible. The former simplifies the latter and then combines it with additional hard-to-know variables, like consumption, population and energy use. All of these estimates end up in what climate wonks call the “social cost of carbon,” or the estimated cost of future damages, in today’s dollars, per ton of carbon dioxide. Policy analysts use this estimate when scoring proposed regulations that affect greenhouse gas emissions one way or another. Not including it would imply that damages from carbon dioxide emissions aren't expected at all; that's desirable, but it isn't true. The climate economics debate, as it occurs in journals, news media and the blogosphere, turns on the assumptions that economists pick when they translate future growth and climate damages into today’s dollars. Often at issue is time discounting. The more activist economists say that a high discount rate carries implicit moral judgments, in that it discriminates against future generations -- which have the same legal and moral value as we do -- by sticking them with the costs of dealing with climate change..."
