THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...Today and Tonight.

WEATHER HAZARDS EXPECTED:
  Limited Thunderstorm Risk.
  Elevated Flooding Risk.
  Elevated Fog Risk.

DISCUSSION:

Unseasonably warm, moist air will spread across the area today as
a warm front lifts north across the area. Moist air over cold
ground and lingering snow pack may result in areas of dense fog
over portions of the area today. Warm, moist air will remain in
place across the area through Tuesday. A series of mid level
disturbances will bring periods of showers and a few thunderstorms
today into Tuesday night. Heavy rainfall in excess of an inch,
and as much as 2 to 4 inches in some areas, will combine with
frozen ground and melting snowpack to result in runoff which may
lead to flooding. Area rivers and creeks will likely see high
water levels over the next several days, with some rivers likely
to go into flood.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
