1042 AM CDT MON JUL 30 2012 /1142 AM EDT MON JUL 30 2012/

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

.DAY ONE...THIS AFTERNOON AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  ISOLATED TO SCATTERED THUNDERSTORMS...A FEW COULD BE SEVERE AND
  MAY PRODUCE:

  WIND GUSTS IN EXCESS OF 60 MPH.
  HAIL TO 1 INCH IN DIAMETER.
  LOCALIZED DOWNPOURS.
  FREQUENT CLOUD TO GROUND LIGHTNING.

   AREAS AFFECTED AND TIMING:

   WHILE ISOLATED THUNDERSTORMS WILL BE POSSIBLE OVER MOST OF
   THE OUTLOOK AREA THIS EVENING INTO THE OVERNIGHT HOURS...
   ISOLATED STRONG TO SEVERE STORMS ARE MOST LIKELY ACROSS FAR
   NORTHERN ILLINOIS NORTH OF THE INTERSTATE 88 CORRIDOR DURING
   THE EVENING HOURS.

  DISCUSSION:

  AN AREA OF LOW PRESSURE WILL MOVE ACROSS THE NORTHERN GREAT
  LAKES REGION TODAY...AND WILL TRAIL A WEAK COLD FRONT ACROSS
  THE UPPER MIDWEST. THE FRONT IS FORECAST TO MOVE INTO FAR
  NORTHERN ILLINOIS LATE THIS EVENING...AND WILL PUSH SOUTHEAST
  ACROSS THE REMAINDER OF THE OUTLOOK AREA OVERNIGHT. WARM...
  FAIRLY HUMID AIR AHEAD OF THE FRONT IS EXPECTED TO BECOME
  MODERATELY UNSTABLE DURING THE AFTERNOON AND EARLY EVENING
  HOURS...WITH ISOLATED TO SCATTERED THUNDERSTORMS DEVELOPING
  ACROSS LAKE MICHIGAN AND SOUTHERN WISCONSIN BY LATE AFTERNOON.
  THESE STORMS WILL LIKELY MOVE SOUTHEAST INTO NORTHERN ILLINOIS
  DURING THE EVENING AHEAD OF THE FRONT. THE COMBINATION OF THE
  UNSTABLE AIR MASS AND INCREASING MID LEVEL WINDS ASSOCIATED WITH
  AN UPPER DISTURBANCE WILL SUPPORT AT LEAST AN ISOLATED THREAT OF
  SEVERE THUNDERSTORMS...WITH THE POTENTIAL FOR DAMAGING WIND
  GUSTS IN EXCESS OF 60 MPH BEING THE MAIN THREAT. THUNDERSTORMS
  SHOULD THEN DIMINISH IN COVERAGE AND WEAKEN AS THE FRONT
  CONTINUES TO MOVE TO THE SOUTHEAST OVERNIGHT.

AN AIR QUALITY ACTION DAY HAS BEEN DECLARED FOR LAKE AND PORTER
COUNTIES OF NORTHWEST INDIANA THROUGH MIDNIGHT CDT TONIGHT...DUE
TO ELEVATED OZONE LEVELS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.

THERE IS A SLIGHT CHANCE OF A LINGERING THUNDERSTORM EARLY
TUESDAY MORNING ACROSS PORTIONS OF NORTHWEST INDIANA.

THERE MAY BE AN INCREASED RISK OF RIP CURRENTS ALONG THE
INDIANA SHORE OF LAKE MICHIGAN TUESDAY AFTERNOON AND TUESDAY
NIGHT.

THERE IS A SLIGHT CHANCE OF PERIODIC THUNDERSTORMS ACROSS THE
OUTLOOK AREA THURSDAY THROUGH FRIDAY...THEN A GREATER CHANCE
OF THUNDERSTORMS SATURDAY AND SATURDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS MAY BE NEEDED ACROSS FAR NORTHERN ILLINOIS THIS EVENING.
