central and southeast Illinois on Monday, along with unseasonably
warm temperatures. Highs ranged from around 60 degrees near I-74,

cold front slowly approaches from the Plains. Several waves of 
showers and thunderstorms are expected across the Midwest, for
tonight through Tuesday. Periods of heavy rain are possible, with
