NORTHEAST ILLINOIS AND NORTHWEST INDIANA.
.DAY ONE...TONIGHT.
WEATHER HAZARDS EXPECTED:
THUNDERSTORMS...A FEW MAY PRODUCE:
HAIL TO ONE INCH.
STRONG DAMAGING WIND GUSTS TO 60 MPH.
AREAS AFFECTED AND TIMING:
THERE IS A CHANCE OF THUNDERSTORMS MAINLY SOUTH OF INTERSTATE 80
LATE THIS AFTERNOON AND EARLY EVENING.
DISCUSSION:
STRONG INSTABILITY HAS DEVELOPED LATE THIS AFTERNOON ACROSS
PORTIONS OF NORTHEAST ILLINOIS AND NORTHWEST INDIANA ALONG AND
AHEAD OF A COLD FRONT. AS THIS FRONT PUSHES EAST ACROSS THE
REGION...A WEAK MID LEVEL WAVE PROPAGATING ACROSS THE REGION
WILL HELP THUNDERSTORMS TO DEVELOP ALONG THIS FRONT.
ALTHOUGH...FLOW ALOFT REMAINS FAIRLY WEAK WHICH WILL LIMIT
OVERALL COVERAGE ACROSS THE OUTLOOK AREA. DESPITE THIS LIMITING
FACTOR...SOME ISOLATED THUNDERSTORMS WILL BE ABLE TO PRODUCE
LARGE HAIL AND DAMAGING WINDS.
.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
THERE IS A CHANCE OF THUNDERSTORMS TUESDAY THROUGH WEDNESDAY.
.SPOTTER INFORMATION STATEMENT...
SPOTTERS WILL LIKELY BE NEEDED LATE THIS AFTERNOON AND EARLY
EVENING.
