Few Tornadoes in MarchApril 1st, 2013 at 2:12 pm by Bill Steffen under Bill's Blog, Weather
Damage from a tornado at Pike Co., Georgia on 3/18/13. This was an EF2 tornado. The U.S. recorded only 17 tornadoes in the whole month of March. We had 24 of 31 days with no tornadoes anywhere in the U.S. and 12 days with no severe thunderstorms anywhere in the U.S. There were no tornado fatalities or significant injuries. Last year, we had 154 tornadoes in March and the 43 fatalities were more than the other 11 months of the year combined. The biggest day for tornadoes last year was March 2nd (it was still winter). The tornado season really calmed down after that. This year will be the opposite with the severe weather season quiet thru the first week of April and then picking up. I think (like last year), the greatest threat for tornadoes will be east of “Tornado Alley”, that runs from NW Texas north to S. Dakota. I look for SE Iowa south to Arkansas, east to NE Georgia and north up thru Illinois, Indiana and Ohio, to have an above average risk for tornadoes. Lower Michigan will be on the northern edge of that risk area and those areas esp. along and south of a line from Benton Harbor to Flint to have a couple of days when we’ll have to be on our guard. Lake Michigan water is cold and that may diminish surface based t-storms in early spring, but remember storms that are not surface based don’t care if there is a cold lake underneath them. Lake Michigan wasn’t even a speed bump for the derecho of 5/31/98. Here’s ACCU-WEATHER’s Severe Weather Outlook, which doesn’t look too bad, with the severe weather farther east than usual and the best chance of severe weather in Michigan during May and June.
Also, worldwide only 2 tropical storms in March…a quiet month.
