Umbrella WeekApril 8th, 2013 at 12:11 am by Bill Steffen under Bill's Blog, Weather
1:55 PM - Gusty winds this afternoon, gusts 35-45 mph possible. Low pressure over Lake Michigan will cross Lower Michigan this PM. Winds are a steady 20-30 mph in the Chicago area from the SW with gusts to 40 mph. Temps. this PM should warm to near 60 south of Benton Harbor to Lansing and into the 50s elsewhere. The heavier rain is shifting north toward Houghton Lake and Cadillac at this hour. Still a chance of a shower this PM, but they will become widely scattered and light. BOTH the new NAM (caribou) and GFS (caribou) give G.R. between 3 a 3 1/2 inches of rain this week! The NAM (caribou) would have a very nasty period of freezing rain Weds. into Thurs. along and just north of U.S. 10 with over an inch of freezing rain and temperatures between 28 and 32 for Cadillac. G.R. hangs around 34 in the rain and Mt. Pleasant is around 32 at the coldest. The NAM (caribou) has a mid-afternoon temperature of 38 for G.R. on Weds. and 36 on Thurs. The GFS is 41/52/41 for Weds., Thurs., Fri. (that’s a mid-aftn. temp….the high temp. would be a couple deg. warmer than that). The warmest on the NAM (caribou) for G.R. is 59 on the hour on Tues. (so maybe a high of 61). The GFS is around 50 Tues. PM. Like I said, keep the umbrellas on and off for at least the next several days. We could easily see 2-4″ of rain across the area, before it all ends with a few snow showers late Thurs. night or Friday. . It’s certainly cold enough for at least a dusting if not an inch of snow Friday night/Saturday AM. The European has the 850 mb. temp. approaching -12C Saturday AM – that’s outrageously cold for mid-April. I’ll update this thread when I can, but it should be active for a few days. This system will produce lots of severe weather from Indiana to the Gulf of Mexico, heavy snow from Colorado/Wyoming to the U.P. There could be another foot-plus of snow in parts of the U.P. before this winter is over. There will be record warmth in the Southeast and record cold from Kansas up into the Dakotas. We’ve had a rather dull last 12 months for severe weather, this is more typical of the April events that we tend to get in the U.S. For current Michigan weather observations and wind speeds, click here.
