The heat and humidity have been on the rise today with temperatures in the mid 80s and dew points in the mid 70s. With that combination, it feels downright tropical! The heat and humidity will create somewhat favorable conditions for storms later tonight.
While a few isolated showers and storms are possible late Saturday afternoon into Saturday evening, the greatest storm chances will be in the late evening and overnight hours. Storms are expected to develop to our north and west in northern Illinois and southern Michigan. They will then move southeast into our region, beginning around 9-10PM and exiting the area by 2-4AM.
Stronger storms are much more likely in northern Illinois and southern Michigan. These storms should weaken as they move our way, but the greatest chance for severe weather will be in our northern counties closer to the Michigan state line. Stronger storms could bring heavy rain and gusty winds. The tornado threat is low, but not zero. The severe threat then decreases from north to south.
Storms overnight won't bring much relief from the heat. Temperatures will be in the upper 80s again Sunday but we should see a bit of a break in the humidity. The heat sticks around for much of next week with highs in the mid to upper 80s.
I'll have the latest on tonight's storms at 6PM and 11PM on ABC21.
