Skies will be clear and the air will be dry tonight as the cooler air rolls into southeast Wisconsin. Temperatures will drop into the low or middle twenties tonight. After an incredibly warm start to December, temperatures return to normal for Wednesday with high temperatures in the upper-thirties under mostly sunny skies. The cool down will be short-lived as warmer air moves back late Wednesday night bringing in a few clouds, also. Thursday will be mostly cloudy with temperatures back into the middle-forties.
