A STRONG COLD FRONT WAS RACING ACROSS THE FORECAST AREA EARLY
THIS MORNING. THE FRONT WAS NEARING THE INDIANA/OHIO BORDER AT
330 AM EST. STRONG WINDS WERE OCCURRING ALONG AND BEHIND THE
FRONT. SUSTAINED WINDS OF 25 TO 35 MPH WITH GUSTS UP TO 55 MPH
WERE OCCURRING AND WILL CONTINUE THROUGHOUT TODAY. GIVEN THESE
STRONG WINDS, THE WIND ADVISORY REMAINS IN EFFECT FOR THE ENTIRE
FORECAST AREA THROUGH TODAY. THE WINDS SHOULD DIMINISH SOME FOR
THANKSGIVING PER HRRR, BUT GIVEN MUCH COLDER TEMPERATURES ON
THANKSGIVING, IT WILL FEEL BLUSTERY THROUGHOUT THE DAY.
LAKE EFFECT SNOW WILL DEVELOP VERY RAPIDLY TODAY GIVEN LAKE
MICHIGAN SURFACE WATER TEMPERATURES > +10C UPSTREAM OF THE
FORECAST AREA. HEAVY LAKE EFFECT SNOW IS NOT EXPECTED GIVEN LOW
INVERSION HEIGHTS AND A SOMEWHAT LIMITED WEST FETCH ACROSS THE
LAKE. HOWEVER, LIGHT TO MODERATE SNOW BANDS WILL DEVELOP AND ARE
EXPECTED TO BRING GENERALLY 3" TO 6" OF SNOW NORTH OF THE TOLL
ROAD BY LATE THANKSGIVING DAY. AREAS OF BLOWING SNOW WILL
ACCOMPANY THE SNOW SHOWERS WITH THE STRONG WIND GUSTS. ABOUT THE
TIME THE LAKE EFFECT SNOW ENDS LATE FRIDAY, SYSTEM SNOW WILL
SPREAD BACK ACROSS THE FORECAST AREA SATURDAY. IT LOOKS LIKE
MILDER AIR WILL EVENTUALLY SPREAD BACK OVER THE AREA, SO HAVE A
RAIN AND SNOW MIX STARTING FROM THE SOUTH EARLY SATURDAY NIGHT.
MUCH MORE DETAIL WILL EVENTUALLY NEED TO BE ADDED TO THE WINTRY
MIX THIS WEEKEND AS THE TIME DRAWS NEAR.
