UPPER LEVEL LOW MOVING INTO SOUTHERN ONTARIO THIS AFTERNOON WITH
SOME HIGH CLOUDS OVER WEST TENNESSEE. TEMPERATURES REMAIN ON THE
COOL SIDE WITH READINGS FROM THE LOWER 40S TO LOWER 50S. AS UPPER
LOW CONTINUE TO MOVE EAST SKIES WILL CLEAR OVER WEST TENNESSEE
SETTING THE STAGE FOR A CLEAR AND CHILLY NIGHT OVER THE FORECAST
AREA. TEMPERATURES BY FRIDAY MORNING WILL BE AT OR SLIGHT BELOW
FREEZING OVER MOST OF WEST TENNESSEE. HIGH PRESSURE WILL BUILD
INTO THE REGION FRIDAY ALLOWING FOR DRY WEATHER AND COOL
TEMPERATURES WITH HIGHS EXPECTED TO BE IN THE 50S. BY FRIDAY NIGHT
WINDS WILL BECOME MORE SOUTHERLY SO TEMPERATURES WON'T BE NEARLY
AS COLD FOR SATURDAY MORNING. AS THE HIGH CONTINUES TO PUSH EAST
SATURDAY DRY WEATHER WILL CONTINUE BUT TEMPERATURES WILL BE WARMER
WITH HIGHS MAINLY IN THE 60S. A COLD FRONT WILL BEGIN TO MOVE
TOWARD THE REGION SATURDAY NIGHT BUT SHOULD NOT BE CLOSE ENOUGH TO
PRODUCE MUCH IN THE WAY OF RAIN. THE FRONT WILL MOVE SLOWLY
THROUGH THE FORECAST AREA ON SUNDAY AND MONDAY BRINGING RAIN TO
THE REGION FOR BOTH DAYS. THERE SHOULD BE ENOUGH RAINFALL BETWEEN
THE TWO DAYS TO PREVENT THE FORECAST AREA FROM HAVING THE DRIEST
NOVEMBER ON RECORD. THE RAIN MAY HANG AROUND UNTIL EARLY MONDAY
EVENING BUT HIGH PRESSURE SHOULD BUILD IN OVERNIGHT BRINGING A
RETURN OF DRY AND COOL WEATHER FOR LATE MONDAY NIGHT AND TUESDAY.
SOME UNSETTLED WEATHER IS EXPECTED FOR WEDNESDAY AS LOW PRESSURE
DEVELOPS OVER THE CENTRAL GULF OF MEXICO AND MOVES NORTHEAST AND
ANOTHER COLD FRONT MOVES THROUGH THE REGION. THE TWO SHOULD SYSTEM
SHOULD MAKE FOR A CLOUDY DAY ON WEDNESDAY WITH A CHANCE OF SOME
RAIN. HIGH PRESSURE BUILDS BACK INTO THE FORECAST AREA BY
WEDNESDAY NIGHT BRINGING MORE DRY AND COOL WEATHER FOR WEDNESDAY
NIGHT AND THURSDAY.
