Click on the image to enlarge. An incredible 48.7% of the Lower 48 states has a snow cover this Monday morning! The average snow depth is also an amazing 5.9″. This compares to only 7.7% on this date last year. The past few days a strong storm has dropped a band of heavy snow from Colorado to the East Coast. Additional snowfall totals include +7″ at Indianapolis, 12.4″ at St. Louis, 12″ at Oakland, Maryland (and still snowing hard there) and 15.3″ at Godfrey, IL. Snow cover this morning is just a trace over much of our area, with some big piles. Snow cover is substantial north of US 10. Wellston in Manistee Co. reports 17″ on the ground in the woods. There’s a 9″ snow cover at the Houghton Lake airport (Houghton Lake is still quite frozen over), 10″ at Cadillac, 11″ at Traverse City, 22″ nine miles WSW of Traverse City, 18″ at Gaylord, 22″ at Ironwood, 26″ at S. Ste. Marie, 27″ at Newberry, 33″ at Paradise, 38″ at the Marquette Airport, 39″ at Twin Lakes, 41″ at Munising, 50″ south of Grand Marais and 53″ at Hoist Basin. The coldest temperature in the U.S. this morning was -20 at Lake Yellowstone WY. Michigan’s coldest was +6 at Wakefield. UP webcams here and here. It sure has been cloudy. In the last 7 days (and today thru noon), we’ve had only 10 hours and 51 minutes of sunshine. That’s only 5.5% of possible sunshine. Paul Pastelok from Accu-Weather notes this morning that the best fit to this March when you look at the pattern across the Lower 48 states is March 1996. The North Atlantic Oscillation stays negatives (but not in the tank), while the Arctic Oscillation (which has been about as negative as you’ll ever see it) heads back toward average (less blocking, which forced the cold, Canadian air into the U.S. This would suggest a return to more average weather in April, but no “heat waves”.
