Big temperature swings on the way along with some storms

Thunderstorms downstate early Wednesday dropped up to two inches of rain and penny size hail Wednesday morning.

Northern Michigan missed out on strong thunderstorms early Wednesday morning that dumped heavy rain and hail downstate.

Penny size hail was reported early Wednesday in the Marshall and Grand Rapids areas with a few spots getting doused with more than two inches of rain. Some street flooding was also noted around the greater Grand Rapids metro area.

Those storms developed on a push of warmer air aloft moving in ahead of a warm front that separates 40's/50's locally from temperatures in the mid-80's as close as Southern Illinois and Indiana. In fact, a few spots in Kansas topped out at 100F Tuesday afternoon giving you an idea on how much heat there is south of that front. This warm front will lift from Central Indiana Wednesday morning and make a push into Northern Michigan Thursday. With that being the case, we expect scattered showers/thunderstorms to pass by and remain in the forecast through at least Friday.

There will be a big temperature difference Thursday with 40's/low-50's across the Eastern U.P./Northeast Lower Michigan, but temperatures along/south of highway M-32 should warm quickly into the 70's south of the aforementioned warm front.

Friday will have the best chance and most widespread chance for rain and some thunderstorms as a weak cold front passes. That will finally clear out the rain and set up a decent start to the weekend with dry weather Saturday and highs in the 60's. There is a risk for a few rain showers Mother's Day with temperatures forecasted to be in the 60's.
