Isolated thunderstorms are expected throughout northern Illinois Tuesday afternoon through evening, with a small chance of some of the storms developing into severe weather, according to the National Weather Service.
“If the storms do become severe, large hailstones and destructive winds would be the main threat,” forecasters warn on the weather service‘s website.
This could include wind gusts of up to 60 miles per hour, which can topple large tree branches. It could also mean hail of up to half a dollar, which could damage cars and sidings of houses, meteorologists said.
The system could arrive in the Chicago area between 3 p.m. and 10 p.m., with the greatest likelihood of severe weather after 5 p.m., weather forecasters said. The local threat will come from the upper Midwest to the southern plains with severe weather shifts Tuesday, according to the weather service.
The system will also leave behind lower temperatures.
“Severe weather threatens (Tuesday) from the Great Lakes down to the southern High Plains,” weather forecasters said. “Much cooler temperatures arriving in the Plains and Midwest by midweek.”
In Chicago, that means Tuesday’s high of 90 degrees will be significantly warmer than Wednesday’s high of just 75 degrees — with even cooler temperatures near the lake.
The far southern suburbs could get another round of rain by Wednesday night, when temperatures drop to the mid-50s, weather forecasters said. A few scattered showers could continue into Thursday morning.
After Thursday’s bottom, when the high is expected to only reach the low 70s, the temperature should start to recover on Friday and Saturday, possibly reaching a high of 80 degrees by the weekend. The showers could also return on Saturday night, forecasters said.
