NEAR TERM
(REST OF TONIGHT AND SUNDAY)
ISSUED AT 914 PM CST SAT FEB 21 2026
BREEZY NW WINDS ARE PREVAILING IN WAKE OF A COLD FRONT LATE THIS
EVENING AND ARE EXPECTED TO CONTINUE FOR THE REMAINDER OF THE
OVERNIGHT HOURS. SOME LIGHT DRIZZLE WAS NOTED ON RADAR IMAGERY,
BUT THIS WILL DISSIPATE QUICKLY OVER THE NEXT COUPLE OF HOURS. AS
DRIER AIR MOVES IN, CLOUD COVER WILL DISSIPATE FROM WEST TO EAST
BETWEEN 06-09Z, RESULTING IN CLEAR CONDITIONS BY EARLY SUNDAY
MORNING. HOWEVER, THE AFOREMENTIONED BREEZY CONDITIONS WILL
PREVENT ANY FOG DEVELOPMENT, DESPITE THE EARLIER RAINFALL. SUNDAY
WILL BE A SHOCK TO THE SYSTEM AS THE NORTHERLY WINDS WILL
REINFORCE THIS COOL, DRY AIR MASS. DON'T LET THE SUNSHINE FOOL
YOU, HIGH TEMPERATURES WILL BE RUNNING ABOUT 20-25 DEGREES LOWER
THAN SATURDAY, WITH MOST LOCATIONS PEAKING IN THE LOW TO MID 40S
(WITH WIND CHILLS IN THE 20S ALL DAY LONG).
SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY)
ISSUED AT 914 PM CST SAT FEB 21 2026
WINDS WILL REMAIN BREEZY SUNDAY NIGHT AND WITH LOW STRATUS
REMAINING TO OUR NORTH AND EAST AS A WEAK SHORTWAVE CLIPS THE
AREA. AS A RESULT, A HARD FREEZE WILL BE IN STORE FOR THE
TENNESSEE VALLEY, WITH LOWS IN THE LOW TO MID 20S BEING COMMON
(AND WIND CHILLS AS LOW AS 6 TO 12 DEGREES)! MONDAY WILL BE AN
EVEN COLDER DAY AS ANOTHER SHORTWAVE TROUGH (AND ITS ASSOCIATED
DRY COLD FRONT) CLIPS THE AREA, WITH HIGHS BARELY MAKING IT ABOVE
THE FREEZING MARK -- PEAKING IN THE MID TO UPPER 30S. ANOTHER
FREEZE WILL BE IN STORE FOR THE AREA MONDAY NIGHT, WITH LOWS
DROPPING TO THE UPPER TEENS TO LOWER 20S. SOME GRADUAL RELIEF
WILL BE IN STORE BY TUESDAY AS HIGH PRESSURE AT THE SURFACE BEGINS
TO BUILD BACK FROM THE WEST. AMPLE SUNSHINE AND SOUTHERLY WINDS
WILL ALLOW HIGH TEMPERATURES TO MODIFY INTO THE LOW TO MID 50S IN
MOST LOCATIONS.
LONG TERM
(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 914 PM CST SAT FEB 21 2026
CLOUDS WILL INCREASE TUESDAY NIGHT INTO WEDNESDAY AHEAD OF AN
APPROACHING FRONTAL SYSTEM. DESPITE THE CLOUD COVER, SOUTHERLY
WINDS WILL HELP TO PUSH HIGH TEMPERATURES BACK INTO THE LOW TO MID
60S. ANOTHER FAST-MOVING TROUGH WILL RIPPLE THROUGH THE TENNESSEE
VALLEY WEDNESDAY NIGHT INTO THURSDAY, BRINGING MEDIUM TO HIGH
CHANCES (50-80%) FOR RAIN SHOWERS ALONG AND AHEAD OF A COLD FRONT.
THIS ACTIVITY WILL TAPER OFF FROM WEST TO EAST THURSDAY NIGHT,
WITH SOME DECENT WETTING RAINS OF BETWEEN 0.5" TO 1.0" FORECAST.
THEREAFTER, WE WILL REMAIN IN ZONAL FLOW ALOFT AND IN A MILD
PATTERN TO CLOSE OUT THE MONTH OF FEBRUARY, WITH PARTLY CLOUDY
CONDITIONS AND SOUTHERLY WINDS KEEPING HIGHS IN THE 60S AND LOWS
IN THE 40S.
