Thundershowers from east of Big Rapids to NW of Holland along a front. There’s a Special Marine Warning for the lakeshore. Could be some hail in those. They’ll move ESE. Rainfall amounts as of 9 PM: 0.37″ Benton Harbor, 0.29″ Holland, 0.28″ Kalamazoo, 0.20″ Battle Creek, 0.18″ Jackson, 0.16″ Grand Rapids, 0.08″ Lansing and just a trace in Muskegon. South Haven is reporting “flurries” at 7 PM. Lower Michigan is in the General Thunderstorm Outlook for this tonight. Most of you won’t see any lightning. With very cool air coming across the warmer water of Lake Michigan, lake-effect rain showers are possible thru Sunday morning and there is a chance of a little small hail, a rumble of thunder or even an isolated waterspout. At 6:30 PM, the mid-Lake Michigan buoy showed a water temperature of 67.3. The buoy just off Holland had a water temperature of 66 and 4.9 ft. waves and the buoy off Ludington reported 4.9 foot waves. We go to -2C at 850 mb (about a mile above ground) Sunday morning, so that will provide a very significant contrast with the 65-degree water (it’ll cool a degree or two by Sunday AM).
