(Maci Tetrick/ABC 57 Meteorologist) It’s a warm and muggy start to the weekend.

Temperatures on Saturday, Aug. 21, are expected to climb close to the 90 degree mark, and it will feel like the low 90s with humidity. There is a chance for some isolated showers or thunderstorms during the afternoon and evening hours.

Sunday is mostly sunny. There is a smaller chance for a stray shower or storm on Sunday afternoon, but despite the storm chances, there should be plenty of time to get outdoors both days this weekend.

If you’re going to Lake Michigan to beat the heat, remember that the lifeguards at Silver Beach are no longer on duty for the season. There is a green flag Saturday, but waves increase in size on Saturday night. There is a red flag on Sunday, so you’re advised to stay out of the water.

Heading into the work and school week, it is still hot and humid with temperatures staying near 90 degrees. There are better storm chances Tuesday through Thursday.
