33 F. high temperature a year ago, March 25, 2011.
1.3" snowfall so far in March. That, and 8 days above 70 F.
8.2" snowfall last March, as of March 25.
March 9: last time the mercury dipped below freezing in the Twin Cities (15 F.)
+17.4 F. The first 24 days of March are running more than 17 degrees above average.
4 days above 70 so far this March in Duluth, Minnesota. Only 8 other days in March dating back to 1875 have reached the 70 degree mark.

1,000+ locations set all-time warm weather temperature records between March 13-19.
"Currently, nearly twice as many record hot days as record cold days are being observed both in the United States and Australia, the length of summer heatwaves in western Europe has almost doubled and the frequency of hot days has almost tripled over the period from 1880 to 2005.
"Extreme weather events over the past decade have increased and were "very likely" caused by manmade global warming, a study in the journal Nature Climate Change said on Sunday." - from a Reuters story below.
Improving Drought Conditions For Minnesota? I hope long-range forecasters are right, but I don't see any quick rebound in the soil moisture department. The map above is from the U.S. Drought Portal, which includes current Drought Monitor conditions and a forecast.

EcoAlert: New Evidence Links Earth's Extreme Weather To Human-Caused Global Warming. Another angle on the same research study from The Daily Galaxy: "The question is whether these weather extremes are coincidental or a result of climate change," says Dim Coumou, lead author of the article. "Global warming can generally not be proven to cause individual extreme events – but in the sum of events the link to climate change becomes clear." This is what his analysis of data and published studies shows. "It is not a question of yes or no, but a question of probabilities," Coumou explains. The recent high incidence of weather records is no longer normal, he says. "It´s like a game with loaded dice," says Coumou. "A six can appear every now and then, and you never know when it happens. But now it appears much more often, because we have changed the dice." The past week illustrates this: between March 13th and 19th alone, historical heat records were exceeded in more than a thousand places in North America." Photo: "Restless Skies".
Fears Of 3C Global Warming By 2050. An excerpt from a story at Google News: "The models showed that average world temperatures are on course to rise by between 1.4C and 3C given mid-range greenhouse gas emissions. According to the findings, the world is very likely to cross the critical "two degrees barrier" at some point this century if emissions continue unabated. Experts believe warming of 2C above pre-industrial levels could trigger runaway climate change that cannot be reversed. Almost 10,000 climate simulations were run using volunteers' home computers. The project, climateprediction.net, was part of the BBC Climate Change Experiment."
Study: Global Temperatures Cloud Rise 5 Degrees By 2050. An update from USA Today: "As the USA simmers through its hottest March on record — with more than 6,000 record high temperatures already set this month — a new study released Sunday shows that average global temperatures could climb 2.5 to 5.4 degrees by 2050 if greenhouse gas emissions continue unabated. The study findings are based on the results of 10,000 computer model simulations of future weather overseen by researchers at Oxford University in the United Kingdom. "These are the first results to suggest that the higher warming scenario could be plausible," says study lead author Dan Rowlands of Oxford. It is a faster rate of warming than most other models predict." Photo: Tony Talbot/AP, USA Today.
