GREEN BAY, WI (WTAQ) - A stormy day is ahead for Wisconsin.
Strong thunderstorms moved into the central part of the state overnight.
The National Weather Service says most of the state will get rain and thunder boomers Thursday morning. Another large wave is expected Thursday afternoon and evening.
Forecasters say there's only a slight chance that the storms will be severe, with large hail and damaging winds. No storm watches or warnings were posted as of early Thursday morning.
Highs in the 70's and 80's are predicted for most of Wisconsin Thursday. It could get close to 90 in the far south.
Once the storms move out early Friday, a cold front is due in -- and that could drop Friday's highs by as much as 15 degrees. Readings in the 60's and 70's are expected Friday.
A clear weekend is in store, but the mercury might not reach 70 anywhere in the state on Saturday and Sunday.
The Weather Service says the Fox Valley will get widespread frost on Saturday night, with many places below freezing for the first time this fall.
