A PAIR OF UPPER LEVEL SYSTEMS AND A COLD FRONT WILL BRING VERY
ACTIVE WEATHER ACROSS THE FORECAST AREA THROUGH FRIDAY. A FAIRLY
STRONG SHORT WAVE WAS MOVING ACROSS THE MID MISSISSIPPI VALLEY.
A LARGE AREA OF MAINLY LIGHT RAIN WAS ASSOCIATED WITH THIS
SYSTEM. THE RAIN WILL SPREAD ACROSS NORTHERN INDIANA TODAY.
TEMPERATURES WILL STAY MUCH ABOVE FREEZING SO SNOW IS NOT
EXPECTED. HOWEVER, A SECOND SYSTEM WILL REACH THE AREA WEDNESDAY
AND BRING ANOTHER ROUND OF PRECIPITATION. THE RAIN WILL CHANGE
TO SNOW EARLY IN THE DAY AS MUCH COLDER AIR SPREADS OVER THE
REGION. LIGHT SNOW ACCUMULATIONS ARE LIKELY ESPECIALLY NORTH OF
THE TOLL ROAD.

THANKSGIVING DAY THROUGH SATURDAY ONLY IN THE LOWER 30S. SOME

THERE ARE MORE CHANCES FOR ACCUMULATING SNOW EARLY NEXT WEEK,
BUT FOR THIS PACKAGE HAVE NOT MADE ANY CHANGES IN THIS REGARD
EARLY NEXT WEEK DUE TO UNCERTAINTY.
