Winter on Training Wheels - Mild Bias Continues
On Friday snow cover at MSP International Airport shrank to a trace. 45 degrees and a third of an inch of rain had something to do with that. According to the National Weather Service that was the end of 56 straight days with at least an inch of snow on the ground. During an average winter an inch or more of snow is on the ground for 90.3 days, based on NOAA data from 1981-2010.
No, it wasn't a "tough winter".
30 inches so far this winter at MSP - we'll see more snow in March, but a higher sun angle and thawing temperatures mean a wetter, sloppier snow with rapid melting.
Wave at the big, moisture-laden storms passing well south of Minnesota this week; more echoes of El Nino. Daytime highs climb to near freezing all week; 40F next Saturday before a Sunday clipper drops an inch or two of slush. We could see 1-2 days in the teens early next week before another rapid thaw. The model solutions for early March look like something I'd expect to see in mid-April. Expect a mild bias to continue.
Meanwhile the strongest cyclone on record in the southern hemisphere just hit Fiji.
Average Snow Cover in the Twin Cities. 90 days a year with at least 1" or more on the ground? Here's an excerpt from Current Results: "For nearly all of winter along with some of early spring and late fall, Minneapolis has at least an inch of snow on the ground. A snowpack that gets to ten or more inches deep can cover the city anytime from November to April. The snow accumulates most during December, January and February. Typically, on six or seven days in January and in February plus another five days in December, the snow depth in Minneapolis tops ten inches..."
Every State's Temperature Trend for Every Season. Yes, Minnesota is warming, especially during the winter months, in fact no other state is warming faster. Here's an excerpt from Climate Central: "...If you look at all four seasons across all of the Lower 48 states — for a grand total of 192 state-season combinations — there are only three instances of cooling. The Dakotas and Iowa are cooling ever so slightly in summer. Otherwise, there’s only one direction temperatures have gone: up. Snow cover in particular plays a role in why winters are heating up so fast from Montana to North Carolina. Or more specifically, it’s a lack thereof. As temperatures rise, snow is decreasing — and in many cases being replaced by rain. Replacing light snow with dark ground means more of the sun’s energy is absorbed leading to a faster increase in warming..."

4 Billion People Face Severe Water Scarcity, New Research Finds. Water, not oil or natural gas, will be the most precious natural resource of the 21st century. Here's an excerpt at The Guardian: "At least two-thirds of the global population, over 4 billion people, live with severe water scarcity for at least one month every year, according to a major new analysis. The revelation shows water shortages, one of the most dangerous challenges the world faces, is far worse previously than thought. The new research also reveals that 500m people live in places where water consumption is double the amount replenished by rain for the entire year, leaving them extremely vulnerable as underground aquifers run down..."

Electric Vehicles Will Triumph Because They're Better, GM Veteran Says. Here's an excerpt from Forbes: "...Set aside all the motivations with climate change, oil dependence—it’s just a better way to do a car. It’s simple.” Electric vehicle sales have been tepid and may remain tepid in the short term. Internal combustion engines will continue to dominate until 2025, Burns predicted, as the nation’s automotive fleet slowly turns over. “It’s just arithmetic.” But as automakers strive to meet the 2025 fuel economy standard—54.5 miles per gallon—they will come to realize that reengineering traditional vehicles is more expensive and difficult than adopting an electric drive train that emits no carbon..."

Meet the Continental U.S.'s First Official Climate Refugees. People have already been dislocated from coastal sections of Alaska, now it's showing up in Louisiana. Next up, Florida? Here's an excerpt from Atlas Obscura: "A slow-motion disaster is unfolding on the Isle de Jean Charles, deep in the Louisiana bayou, where a group of residents just received $48 million in federal funding to relocate. These are the first official climate refugees in the lower 48 states. The Biloxi-Chitimacha-Choctaw Indians have lived in southern Louisiana for centuries, and, since 1880, a band of them inhabited the Isle. But several factors, including climate change, the Deepwater Horizon oil spill, and a series of destructive hurricanes have meant that the Isle de Jean Charles has lost 98 percent of its land since 1955..."
