A warm front brought scattered showers and thunderstorms to
central and southeast Illinois on Monday, along with unseasonably
warm temperatures. Highs ranged from around 60 degrees near I-74,
to 70 degrees south of I-70.

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
total rainfall amounts of 2 to 4 inches expected by midweek. This
could cause significant rises on area streams and rivers. Southerly
wind flow will produce spring-like temperatures across the 
region, through Tuesday. As the cold front pushes through on 
Tuesday night, lingering rain could change to light freezing rain,
primarily northwest of I-55.

Low temperatures tonight will range from the upper 20s in northern
Iowa, to the mid 60s in southern Illinois. Highs on Tuesday will
