What a difference a year makes!March 16th, 2013 at 1:46 am by Bill Steffen under Bill's Blog, News, Weather
These are the 6-10 day temperature and precipitation forecasts from the Climate Prediction Center. Wow! Look at all that blue! March 2012 high temperatures starting with the 14th: 80, 74, 79, 78, 75, 81, 83, 87, 85. The month was 15 degrees warmer than average! This year thru Friday we are running 1.3 degrees cooler than average and we’ll only add to that in the next 10 days. You can see we’re also in the green higher than average precipitation probabilities and some of that will be snow. The high temperature map from Friday shows a lot of cold air north of the U.S. Canadian border poised and ready to push into the Lower 48 states. Could this be the coldest end to March in the U.S. since 1996? GFS 7-day snowfall doesn’t snow a lot for us (a little), but it’s snowing quite a bit down into S. Missouri and thru the Ohio Valley. GFS showing an amazingly cold end to March across the U.S. east of the Rockies. In fact, look at the GFS (remember, it’s the GFS…so don’t get too excited) for late March and April. If this is right…this means the blossoms definitely won’t come out early this spring and we’ll continue to see very few tornado days. This is hard to believe, but we have had only ONE tornado (a small EF1 on 3/5 in E. Georgia) in the entire U.S. in the first 15 days of March! It’s not just here in the U. S. Tanks have been called out in Hungary to rescue snowbound motorists from three-foot drifts. BBC also reports “Heavy snow paralysed parts of south-eastern Poland, where police were redirecting heavy lorries for fear they would get stuck.” and an Arctic blast in Spain. Heavy snow and temperatures below zero in Moscow. Mid-winter snow, ice and cold has hit Britain, France, Belgium, the Netherlands and Germany. Cool pictures here. Temperatures have been a little colder than average this month all the way across Russia into Siberia. The Antarctic icecap is at a historic record highest extent (records since 1979). The Antarctic icecap (which has been doing the opposite of the Arctic icecap) has been growing steadily for the past 25 years. Here’s the Arctic icecap extent for the past 9 years. The low temperature at Summit Station in Greenland was -52F Friday morning! Friday morning 22.2% of the Lower 48 states had a snowcover of 1″ or more. That’s slightly above the 10-year average of 21.3% for March 15, and well above the 10.1% we had in the midst of the warm March 15th last year.
Overnight model data. SHIVERIN’ SNOWMAN! The GFS has high afternoon high temperatures Tuesday to Thursday for G.R. at 27 – 21 – 28! The European has 2 PM temperatures of 24 on Tue., 26 on Weds., and 30 on Thu. The European, for you real weather geeks, has our thickness from 510 to 516 for 48+ hours from Tues. AM to Thurs. AM. Nothing like a shot of lake-effect snow in the 2nd half of March! The Whitecaps called me Friday, a little concerned about the pattern we’re in. Whether the baseball’s are fair or foul, whether the weather is fair or foul, it’ll be nice to see the boys of summer back in town! Have a good weekend. Woo Hoo for my Wisconsin Badgers…a big couple of b-ball wins. Had a nice time at the Leadership Breakfast this AM and the Muskegon Skywarn Meeting this PM…now off to a dinner downtown. Busy day! Sunday I have to work on Science Olympiad.
Quick 6 PM UPDATE: With the 1-3″ snowfall last night, season snowfall is up to : 60.3″ Grand Rapids, 60.6″ Kalamazoo (WMU), 26.9″ Lansing, 94.5″ Muskegon.
