Severe T-Storm Watch PossibleAugust 30th, 2014 at 2:32 pm by Bill Steffen under Bill's Blog, Weather
The Storm Prediction Center has issued a meso-discussion about possible severe weather developing this afternoon across a large section of Lower Michigan and parts of northern Indiana and northeast Illinois. SPC says: “THE RISK FOR SEVERE THUNDERSTORMS WILL INCREASE THROUGH THE AFTERNOON. CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED…AND THE ISSUANCE OF A SEVERE THUNDERSTORM WATCH IS POSSIBLE…DMGG WIND GUSTS SHOULD BE THE PRIMARY SVR RISK…. MARGINALLY SVR HAIL…AND POSSIBLY A WEAK TORNADO…CANNOT BE RULED OUT WITH MORE SUSTAINED… DISCRETE/SEMI-DISCRETE CONVECTION.” Here’s Grand Rapids radar (line of showers and storms from Houghton Lake to Lowell to N. Van Buren Co. as I write this). Here’s regional radar. Here’s the latest Grand Rapids NWS discussion. See more links in the 2 threads below this one.
No severe weather reports…but gusty winds, heavy rain and lightning. Not much from G.R. west (a bit of a lake shadow perhaps.

Gusts to 30-35 mph throughout much of the area. The Port Sheldon buoy is reporting waves of 3.8 ft. and a water temp. of 70.
