More (light) Snow, Continued CoolMarch 3rd, 2014 at 11:59 am by Bill Steffen under Bill's Blog, Weather
The high temperature of 15° tied for the 13th lowest high temperature ever in G.R. during the month of March. I must be getting used to it, because it didn’t feel quite that cold. The full March sun and a nearly calm wind made a difference. The first map on the left is snow cover today across the U.S. and southern Canada. 57.3% of the Lower 48 states has a snow cover this morning. The average snow cover is a healthy 7.1″. The middle map is snow cover across the Western Great Lakes. This area has a 100% snow cover this morning with the least at any weather station on the map 1.4″ and the most 59″. The average snowfall for weather stations on that middle map is 21″! The average water equivalent in the snowcover on the middle map is 4.6″. That’s a lot of water locked up in that snow. Over much of the area, the ground is either well-frozen. A significant rain combined with snowmelt would create significant flooding. Grand Rapids has 19″ of snow on the ground. Over the weekend, we peaked at 20″. The most snow we have ever had on the ground in any March before now was 15″. Other snowcover reports: 9″ Big Rapids, 13″ Alma, 15″ Hopkins and Hastings, 16″ Lansing, 20″ Holland and Kalamazoo, 21″ Muskegon, 24″ Cadillac, 25″ Traverse City, 31″ Charlevoix. Snowfall Sunday totaled 8.7″ at the southern end of Lake Michigan at Porter, Indiana and 8.4″ at Portage, Indiana. Hillsdale MI had 5.5″ and Chicago picked up another 4.5″.
The map on the right is low temps. this morning. By my count, 18 states had below zero temperatures somewhere and some of the numbers are very cold. We made -8 in G.R. (31° below average). Other lows included -5 in Muskegon, -6 in Kalamazoo, -8 at the Regional Airport in Holland, -9 in Lansing, -10 in Battle Creek, -19 at Big Rapids, -20 at the Manistee Airport, -23 Cadillac, -28 Baldwin, -30 Pellston, -32 at Leota in Clare Co. and -34 at Indian River. The coldest spot in the U.S. was -36 at Crane Lake MN.
The satellite loop shows lots of ice on the Great Lakes, but still some open water (especially on Lakes Michigan and Ontario) to generate some lake-effect clouds. Roughly 2,300 flight delays in the U.S. at noon (Monday). Tropical Storm Kofi threatens Figi.
