Ice Storm and FloodingApril 1st, 2014 at 12:19 pm by Bill Steffen under Bill's Blog, Weather
Calm and dry weather on Weds with highs in the upper 40s to near 50. Rain/Freezing rain starts Weds. night (Weds. evening may still be dry). The most like time for freezing rain will be late Weds. night into Thurs. morning and the most likely area will be north of I-96. The morning NAM (caribou) gives G.R. 0.37″ Thurs. and then another 1.07″ Thurs. night into Friday. Big Rapids gets 1.49″. That would be significant enough to cause some moderate flooding. The rain may end with some flurries early Saturday. Sunday should be the better half of the weekend weatherwise. Check out the Storm Prediction Center Severe Outlook Areas to see the large areas that may get severe thunderstorms and possible tornadoes. Here’s the Severe Weather Discussion for Friday.
-Freezing rain potential develops Wednesday night and remains possible through Thursday night.
-Highest threat for freezing rain Wed night and early Thu will be south of a Pentwater to Alma line.
-Highest threat for freezing rain late Thu and Thu night will be along and north of a Holland to Lansing line.
-Amount of icing is uncertain due to uncertainty with temperatures.
-Already elevated river levels will see additional rises with liquid precipitation amounts of half an inch to one inch expected through Friday.
