  Kendall County in northeastern Illinois...
  La Salle County in north central Illinois...
  DuPage County in northeastern Illinois...
  Cook County in northeastern Illinois...
  Livingston County in central Illinois...
  Lake County in northeastern Illinois...
  Will County in northeastern Illinois...
  Eastern Lee County in north central Illinois...
  De Kalb County in north central Illinois...
  Grundy County in northeastern Illinois...

* Until 900 AM CST

* At 405 AM CST, Doppler radar indicated a large area of showers and
  isolated thunderstorms extending from eastern Missori into
  northeast Illinois. Pockets of moderate to heavy rain are embedded
  within this area. These showers and thunderstorms will continue
  through the early morning hours across the advisory area. Rainfall
  totals of three quarters of an inch to an inch and a quarter are
  likely by the time the rain ends later this morning. Due to the
  frozen ground, much of the rainfall will become immediate run off
  and result in ponding of water in low lying and poor drainage
  areas.

* Some locations that may will experience some minor flooding
  include...
  The Chicago metropolitan area, as well as the LaSalle-Peru,
  DeKalb, and Pontiac areas.

Motorists this morning should exercise caution and be on the look
out for standing water on roadways.

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

.DAY ONE...Today and Tonight.

WEATHER HAZARDS EXPECTED:
  Elevated Thunderstorm Risk...with an associated:
      Limited Tornado Risk.
      Limited Hail Risk.
  Limited Flooding Risk through mid morning.
  Elevated Snow Risk late tonight.

DISCUSSION:

Showers and isolated non-severe thunderstorms are likely early
this morning, ending from the southwest during the early to mid
morning hours. Locally heavy rainfall in excess of an inch is
possible with this batch of rain, which could cause some minor
flooding and ponding of water in low lying and flood prone areas.

Scattered thunderstorms are expected to re-develop this afternoon
over western Illinois, then track east across the northern
Illinois late this afternoon into early this evening. Widespread
severe weather is not expected, however, conditions are such that
a brief tornado or a bit of hail cannot be ruled out this
afternoon, mainly west of the Fox River.

Rain showers will change to snow showers tonight, mainly after
midnight. There is a chance of some heavier snow showers
developing north of I-88 and I-290, which if they develop could
drop a quick inch or two of slushy accumulation.

Finally, localized ice jam flooding will remain a threat on area
rivers.

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

Localized ice jam flooding will remain a threat on area rivers.

.SPOTTER INFORMATION STATEMENT...

Spotters activation is not expected, but spotters are encouraged
to monitor weather conditions this afternoon and early evening.

GENERAL STORM MOTION OF THE DAY:

Northeast at 40 mph.
