THE AREA OF LIGHT SNOW ACROSS CENTRAL AND EASTERN ILLINOIS THIS
MORNING IS QUICKLY TAPERING TO FLURRIES. UPSTREAM OBS ACROSS SOUTH
CENTRAL WISCONSIN AND NORTHERN ILLINOIS ARE ALREADY PAINTING THE
PICTURE OF HOW THIS AFTERNOON WILL LOOK AROUND HERE. THE
OVERWHELMING MAJORITY OF MODEL GUIDANCE SUPPORTS A LARGE POCKET OF
CLEARING MOVING SOUTHWARD ACROSS CENTRAL ILLINOIS BY AFTERNOON,
AND THIS IDEA MAKES SENSE GIVEN THE LARGE SCALE SUBSIDENCE/RIDGING
MOVING IN BEHIND THE DEPARTING UPPER-LEVEL SHORTWAVE TROUGH. WITH
AT LEAST A FEW HOURS OF SUNSHINE THIS AFTERNOON, TEMPERATURES ARE
STILL ON TRACK TO REACH INTO THE MID 30S, THOUGH WITH THE FREQUENT
NORTHERLY WIND GUSTS BLOWING BETWEEN 20-30 MPH, IT WILL FEEL MUCH
COOLER THAN THAT. NO CHANGES HAVE BEEN MADE IN THE FORECAST FOR
TONIGHT THROUGH SATURDAY.
