Hazardous weather outlook, Apr 3, 4:28 PM CDT, 10 hours 47 minutes before

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
428 PM CDT SUN APR 3 2011

ILZ003>006-008-010>014-019>023-032-033-039-INZ001-002-010-011-019-

428 PM CDT SUN APR 3 2011 /528 PM EDT SUN APR 3 2011/

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

.DAY ONE...TONIGHT.

  WEATHER HAZARDS EXPECTED:

  THUNDERSTORMS...SOME MAY BE SEVERE WITH THE POTENTIAL TO
  PRODUCE: CLOUD TO GROUND LIGHTNING. LARGE HAIL OF 1 TO 2 INCHES.
  STRONG DAMAGING WIND GUSTS IN EXCESS OF 60 MPH. LOCALLY HEAVY
  RAINFALL. ISOLATED TORNADOES.

  AREAS AFFECTED AND TIMING:

  THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A COLD FRONT ACROSS
  SOUTHEAST IOWA VERY LATE THIS AFTERNOON OR EARLY THIS EVENING...
  AND THEN SPREAD EAST INTO ILLINOIS DURING THE EVENING HOURS AND
  INTO NORTHWEST INDIANA DURING THE LATE EVENING AND EARLY
  OVERNIGHT HOURS. THUNDERSTORMS WOULD LIKELY AFFECT NORTH CENTRAL
  ILLINOIS AFTER 7 OR 8 PM...REACHING NORTHEAST ILLINOIS AFTER 9
  OR 10 PM AND NORTHWEST INDIANA TOWARD MIDNIGHT.

  DISCUSSION:

  DEEP LOW PRESSURE OVER NORTHERN IOWA WILL TRACK NEAR THE
  ILLINOIS WISCONSIN BORDER TO SOUTHERN LAKE MICHIGAN THIS
  EVENING...AND TO CENTRAL LOWER MICHIGAN BY MONDAY MORNING. VERY
  WARM AND MOIST AIR WILL CONTINUE TO SPREAD NORTH ACROSS THE
  OUTLOOK AREA AHEAD OF THE LOW THIS EVENING. THUNDERSTORMS ARE
  EXPECTED TO DEVELOP ACROSS SOUTHEAST IOWA AND NORTHERN MISSOURI
  ALONG A COLD FRONT TRAILING FROM THE LOW TOWARD EVENING...AND
  WILL MOVE INTO NORTHERN ILLINOIS DURING THE EVENING HOURS AND
  INTO INDIANA OVERNIGHT. THE COMBINATION OF WARM AND MOIST LOW
  LEVEL AIR...AND STRONG WINDS BOTH AT THE SURFACE AND ALOFT WILL
  SUPPORT THE DEVELOPMENT OF SEVERE STORMS...THOUGH WARM AIR ALOFT
  WILL LIKELY LIMIT THE DEVELOPMENT OF THUNDERSTORMS EXCEPT NEAR
  THE COLD FRONT. THEREFORE THE GREATEST POTENTIAL FOR SEVERE
  WEATHER IS EXPECTED TO BE OVER WESTERN PORTIONS OF ILLINOIS AND
  THE WESTERN PORTIONS OF THE OUTLOOK AREA. STORMS MAY INITIALLY
  BE MORE DISCRETE AND MAY POSE A THREAT OF VERY LARGE
  HAIL...DAMAGING WINDS AND EVEN ISOLATED TORNADOES DURING THE
  EARLY TO MID EVENING HOURS. STORMS SHOULD EVENTUALLY MERGE INTO
  A SQUALL LINE...WITH THE MAIN THREAT SHIFTING TO DAMAGING WIND
  AS THE LINE PUSHES ACROSS THE EASTERN PORTIONS OF THE OUTLOOK
  AREA OVERNIGHT. SOME DECREASE IN INSTABILITY OVERNIGHT WILL
  LIKELY RESULT IN SOME WEAKENING OF STORMS AS THEY MOVE TO THE
  EAST. THE POTENTIAL FOR LOCALLY HEAVY RAINFALL WILL ALSO
  INCREASE OVERNIGHT...PARTICULARLY ACROSS SOUTHERN PARTS OF THE
  OUTLOOK AREA.

  GUSTY SOUTH WINDS AHEAD OF THE LOW WILL ALSO PRODUCE GUSTS UP TO
  45 MPH PRIOR TO SUNSET THIS EVENING.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

THERE IS A CHANCE OF THUNDERSTORMS MONDAY MORNING ACROSS
SOUTHEASTERN PORTIONS OF THE OUTLOOK AREA...MAINLY SOUTHEAST OF A
LINE FROM PONTIAC TO VALPARAISO.

THERE WILL BE ANOTHER CHANCE OF THUNDERSTORMS THURSDAY AND
THURSDAY NIGHT...AND AGAIN SATURDAY NIGHT AND SUNDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS MAY BE NEEDED THIS EVENING THROUGH THE NIGHT TONIGHT.
