Forecast: Flood Watch in effect starting this afternoon
Chicagoland will be watching for potentially strong to severe thunderstorms with the threat of damaging winds, large hail and isolated tornadoes this afternoon and continuing through Thursday evening.
Scattered showers and thunderstorms are possible this morning with the chance for rain rising through the day. A breeze off the lake will keep temperatures cooler today, but temperatures are expected to rise tonight as a warm front moves through the region.
Highs Thursday are forecast to reach the low 70s ahead of a cold front. The chance for storms will continue and heavy rainfall potential has prompted the National Weather Service to issue a Flood Watch from Wednesday afternoon through Friday morning. Up to 4” of rain may fall in some locations across the area during that time.
Behind the cold front we can expect much cooler conditions Friday and into the weekend.
