After a rainy month so far for May, Mother Nature decided to turn up the thermostat and let us swelter for a couple of days. Have no fear, it's Michigan and it will be chilly by the weekend.

It's been a wet month and cool month so far, and usually we get a reprieve between using our heat and cranking up the AC, but not this week.

The heat index (actual temp plus humidity factored in) will hit 93 today in Grand Rapids, and it will be the warmest day of the year at 88 degrees.

In fact, GR should be the warmest city in the state today, but there's no prize for that.

Stay cool out there!
