Much warmer temperatures this week, but also a chance of - yes - thunderstorms

That's right.  We may not be done with thunder and lightning quite yet after all. Despite a very brisk morning here in the thumb, temperatures are expected to rise into the 60s. This should create enough temperature differential to ignite thunderstorms in some areas of the state.

This morning's NAM4KM run is the most aggressive regarding thunderstorm development over lower Michigan this evening.

The warm-up will continue after today.  By Wednesday, some places to the south may even be looking at temperatures in the mid to upper 70s once again.
