KEY MESSAGE 1...
A SHORTWAVE WILL MOVE ACROSS THE AREA TONIGHT, BRINGING LIGHT
PRECIPITATION TO THE AREA, AND A REINFORCING SHOT OF COOLER AIR.
PRECIPITATION ACROSS MOST OF THE AREA SHOULD GENERALLY FALL IN THE
FORM OF RAIN, BUT ACROSS THE HIGHER TERRAIN, SNOW OR A RAIN/SNOW MIX
IS EXPECTED. WITH THE COLDER AIR MOVING INTO THE REGION, FROST
ADVISORIES AND FREEZE WARNINGS HAVE BEEN ISSUED FOR MUCH OF THE
AREA, OUTSIDE OF THE EXTREME SOUTHERN ZONES. IN TERMS OF THE
LOWLANDS, BEST AREA FOR THESE CONDITIONS IS SE OHIO, NE KY AND MID
OHIO VALLEY ZONES, WHERE BETTER CLEARING WILL TAKE PLACE AS THE WAVE
CONTINUES TO TREK SOUTH AND EAST. SHELTERED VALLEYS WILL BE MOST
SUSCEPTIBLE TO THE COLD. MONDAY WILL ALSO BE QUITE COOL AS OF LATE,
WITH A NORTHERLY FLOW ACROSS THE AREA.
HIGH PRESSURE WILL THEN BUILD INTO THE REGION FOR MONDAY INTO
TUESDAY, WITH A VERY DRY AIR MASS TAKING HOLD. AFTERNOON RELATIVE
HUMIDITY BOTH DAYS WILL BOTTOM OUT IN THE 20 TO 30 PERCENT RANGE,
WITH POCKETS OF TEENS NOT COMPLETELY OUT OF THE QUESTION. WITH THE
DRY AIR MASS IN PLACE, EXPECTING A CLEAR, COLD NIGHT FOR MONDAY
NIGHT. A FREEZE WATCH HAS BEEN ISSUED FOR MONDAY NIGHT/TUESDAY
MORNING.

A RETURN OF ABOVE NORMAL TEMPERATURES, AND VERY DRY CONDITIONS, WITH
CONTINUED FIRE WEATHER CONCERNS. HOWEVER, BY THE END OF THE WEEK
