Lots of SnowMarch 21st, 2013 at 3:50 am by Bill Steffen under Bill's Blog, Weather
Click on the images to enlarge. The map on the right is snow cover across North America. On Wednesday, 29.3% of the U.S. had a snow cover of 1″ or more. That was second to 2006 for most snow on the ground in the U.S. on March 20 over the last 10 years. The average snow depth is a healthy 5.1″. Northern Hemisphere snow cover for the period November through February was the 2nd highest since records began in the winter of 1966-67. Northern Hemisphere snow cover has been above average for the last several years. With the way this March is going in the U.S. and Europe, we could easily set a new record for snow cover for the period Nov. 1 to Mar. 31. The latest 6-10 day and 8-14 day outlooks from the Climate Prediction Center certainly keep the cool pattern locked in for the next two weeks. The low temperature before midnight for Weds. was 11 in G.R. Grand Rapids is now 3.7 deg. below average for March and Kalamazoo is 4 degrees cooler than average for month. This looks like it’ll mark the biggest turnaround from warm to cool (from year to year) that we have ever had in G.R. We have had at least a trace of snow on 14 of 21 days in March. We have had only five days this month with above average temperatures. This has also been a cloudy winter. Here’s the percent of sunshine by month with the average in ( ): December: 18% (22%), January 25% (29%), February 18% (39%), March 35% (46%).
The GFS now keeps the bulk of the snowstorm Sunday/Monday to our south. The GFS (caribou) gives G.R. about 1/2″ of snow on Monday and 1.2″ for Kalamazoo (with a little mixed rain). The European gives G.R. a dusting of snow oday and a dusting next Tue. with 1/2 to 1″ next Weds.
