ABC7 Meteorologist Larry Mowry said there is concern for ice accumulation in the far north suburbs, mainly in parts of Lake and McHenry counties. However, the heavier the rain that falls, the less likely it will be to ice up.

Elsewhere in the Chicago area, heavy rain will be likely with 1 to 2 inches possible. The highest totals will be southeast of the I-55 corridor, and you might even hear some rumbles of thunder.

Mowry said the precipitation is expected to begin across the area between 8 to 9 a.m. and will continue all day into the evening. Some localized flooding is possible due to heavy downpours.

Temperatures will warm Wednesday night into Thursday, with temps close to 50 degrees Thursday morning before falling again the afternoon.

Friday will be a cold, blustery day with a high of 28 degrees. A few flurries are possible Friday night.
