Northern Illinois, southern Wisconsin, northwest Indiana and eastern Iowa all were under tornado watches Saturday afternoon, the harbinger of a sometimes stormy holiday weekend in the Chicago area, with a chance of more flooding and severe thunderstorms.
The declaration of the tornado watch lasts until 8 p.m. Saturday in northern Illinois. By a little before 2 p.m., severe thunderstorms had developed west of Chicago in Ogle County and were moving northeast around 30 mph, according to the National Weather Service.
Thunderstorms were expected at several points over the weekend but Saturday was expected to see the worst of it, according to weather service meteorologist Matt Friedlein.
The storms will be scattered and moving a little quicker than storm systems that hit the area earlier this week, but the risk of flooding isn’t expected to be as bad.
“It’s not as elevated of a flooding threat as it was last weekend,” Friedlein said.
Still, there is an isolated risk of some flash flooding in the northern part of the state, including the Chicago area, as well as a threat of possible tornadoes.
Storms should hit Chicago around 3 p.m. Saturday and stay well into the evening, ending around 9 p.m., according to Friedlein.
Temperatures will peak in the mid-60s near the lake but reach the upper 70s further inland.
That humidity will last through the holiday weekend, with temperatures reaching mid-80s Sunday and Monday.
There is still a chance of thunderstorms Sunday and Monday but it will be much more scattered compared to Saturday.
