Risk Of A Thaw. The last time it was above freezing at MSP was January 29 (34F). Watch the solid red line, marking the 32F isotherm, surging north Tuesday, again Wednesday as steering winds aloft become more westerly. Colder weather returns by next weekend, but not the polar chill of a few weeks ago. 2-meter NAM temperatures guidance courtesy of NOAA and Ham Weather.

Faint Echoes Of The Polar Vortex. Wave goodbye to the coldest lobe of polar air, courtesy of a buckling jet stream. What has been impressive (at least to me) is the sheer persistence of Yukon air pouring south of the border since early December, how the jet stream configuration has become locked, treating Alaska, Greenland and Europe to near-record warmth; bitter air stalling over much of the central and eastern USA.

Sochi Among The Warmest Winter Olympics Host Cities. You’ve seen video of fans in shirtsleeves, athletes taking their shirts off to stay cool – during the Winter Olympics in Sochi. Here’s some perspective on the venue from NOAA’s climate.gov: “The 2014 Winter Olympics are taking place from February 7-23, 2014, in Sochi, Russia. Sochi will be among the warmest cities to have hosted a Winter Olympic Games, with overnight low temperatures of 39°F (4°C) on average in February, and average daytime highs of 50°F (10°C). The map (above) shows the average minimum temperatures (overnight lows) for January and February from 1911-2011 for all the locations that have hosted the Olympic Winter Games, starting with Chamonix, France, in 1924 and ending with Sochi, Russia, in 2014…”

“We are still waiting for winter to arrive. We had springlike temperatures since December, 10-12C every day. The birds are singing; my roses started blooming in mid-January.”

Snow On The Ground In Portions Of 49 States. Only Florida is entirely snow-free. That’s comforting. USA Today has the story; here’s a clip: “Snow is on the ground in 49 out of the 50 states — only the Sunshine State of Florida is completely snow-free, according to a map produced Thursday morning by the National Oceanic and Atmospheric Administration. (This doesn’t mean that those 49 states are snow-covered, of course, only that some part of each state has snow.)…”

California’s Drought Could Be The Worst In 500 Years. Mother Jones explains how the historic drought gripping the west may soon show up at a grocery store near you; here’s an excerpt: “The Golden State is in the midst of a three-year drought—and scientists believe that this year may end up being the driest in the last half millennium, according to University of California-Berkeley professor B. Lynn Ingram. Californians are scared, with good reason: Fire danger in the state is high, and drinking-water supplies are low. But the drought will have repercussions outside the state’s borders, as well…”

Drought-Stricken California, Other States Prepare For Landmark Year In Fires. The fact that fires are burning during the height of the (alleged) rainy season on the west coast doesn’t bode well for later in 2014, when things really heat up. Here’s a clip from The Washington Post: “…We’re seeing summertime weather conditions in January,” Hein said as two of his crews continued to mop up the smoking remnants of the Red Fire. “If we don’t get some rain now, just imagine what the summer is going to be like.” Across the Western United States, officials tasked with fighting forest fires worry that a confluence of factors, including climate change and human development, are conspiring to create conditions ripe for a landmark fire year...” (File photo above courtesy of ThinkProgress).

Stroke Risk Tied To Cold, Humidity, Weather Swings. Here’s a clip from a story at boston.com that caught my eye: “There may be a link between weather and the risk of suffering a stroke, say researchers who analyzed climate trends and hospital records on millions of Americans. Cold weather, high humidity and big daily temperature swings seem to land more people in the hospital with strokes. As it got warmer, risk fell — 3 percent for every 5 degrees, the study found. ‘‘Maybe some of these meteorological factors serve as a trigger,’’ said Judith Lichtman, a Yale University stroke researcher who led the study…”

ABOUT ME
Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune startribune.
Miss your weather report’s in the Twin Cities
Hope you are doing well 🙂
I’m a Weather Geek; I like to not only know what but why. Ex. Why is it still pouring snow when the radar shows nothing over us? (Reason being, according to our local NWS, that their radar is set to 5000 feet, we are in a very hilly section, and the radar doesn’t “see” cloud activity below 5000 feet!) Please, keep on giving us weather facts and backstories on WeatherNation!
