northern Illinois and northwest Indiana after midnight
tonight. Rain rates up half inch per hour are possible, with
isolated thunderstorms producing rain rates up to one inch
per hour. Soil frost depths of 8 to near 20 inches, with the

ice cover also remains in place along stretches of the Rock
River, Fox River, and their tributaries. River rises may
break up ice cover and cause localized ice jams.
