Heat, humidity and storms this weekend
Winds shift to the southwest and increase today as a warm front moves through northern Illinois into Wisconsin. Moisture from overnight showers and thunderstorms will evaporate back into the air as the sun breaks out, making it feel more humid almost from the start.
A weak cold front will pass through the area Sunday, but a stronger cold front is not expected to push through northeast Illinois until later Monday or early Tuesday. The National Weather Service Storm Prediction Center has northern Illinois outlooked for potential severe thunderstorms Saturday through Monday. A wide range in rainfall amounts may be recorded over the metro area as slow-moving storms could give well in excess of an inch in some areas.
After a midweek cool-down, another warm-up is in store next weekend. The Climate Prediction Center indicates warm high pressure will dominate the following week with little or no rainfall.
