SHORT TERM
(REST OF TODAY THROUGH MONDAY)
ISSUED AT 1130 AM CST SUN NOV 23 2025
BROAD NORTHWESTERLY FLOW ALOFT IS SITUATED ACROSS THE REGION ALONG
WITH A SURFACE HIGH PRESSURE NOW CENTERING NEAR THE TENNESSEE
VALLEY. DRY, STABLE WEATHER WILL RESULT TODAY WITH TEMPERATURES IN
THE UPPER 50S TO THE MID 60S. WE'LL WATCH FOR FOG/LOW CLOUD
DEVELOPMENT AGAIN TONIGHT AS WELL.
HIGH PRESSURE WILL PROGRESS EAST TOMORROW WHICH WILL COINCIDE
WITH HEIGHT RISES AND SOUTHERLY LOW-LEVEL FLOW. TEMPERATURES AND
MOISTURE VALUES WILL RISE SLIGHTLY ALONG WITH AN INCREASE IN CLOUD
COVER AS A SHORTWAVE APPROACHES THE LOWER/MID MISSISSIPPI VALLEY.
SOME RAIN SHOWERS ARE POSSIBLE EAST OF I-65 TOMORROW AFTERNOON.
LONG TERM
(MONDAY NIGHT THROUGH NEXT SUNDAY)
ISSUED AT 1130 AM CST SUN NOV 23 2025
AN UPPER-LOW CURRENTLY SITUATED NEAR THE FOUR CORNERS IS PROJECTED
TO ADVANCE TOWARD OUR REGION MONDAY NIGHT. THIS COINCIDES WITH
INCREASING TEMPERATURES AND MOISTURE VALUES PREVIOUSLY DESCRIBED.
CHANCES FOR RAIN SHOWERS WILL CONTINUE TO INCREASE ACROSS MIDDLE
TENNESSEE MONDAY NIGHT OWING TO INCREASING WARM, MOIST ADVECTION
AND A LOW-LEVEL JET. RAIN SHOWERS, AND A FEW THUNDERSTORMS WILL BE
QUITE WIDESPREAD ALONG/AHEAD OF THE ADVANCING COLD FRONT SET TO
MOVE ACROSS THE AREA TUESDAY MORNING. DESPITE FAVORABLE DEEP-LAYER
WIND SHEAR AND FORCING, INSTABILITY LOOKS VERY MEAGER ACROSS THE
AREA MONDAY NIGHT DUE TO LIMITED MOISTURE RETURN IN THE BOUNDARY
LAYER. HOWEVER, SOME INCREASE IN PRE-FRONTAL INSTABILITY IS
POSSIBLE TUESDAY MORNING/AFTERNOON WITH HEATING. SHOULD FRONTAL
FORCING STILL BE AROUND BY THEN WE COULD SEE A STRONG/SEVERE
THUNDERSTORM. AT THIS TIME BEST CHANCES ARE GENERALLY SOUTH OF
I-40, BUT FORECAST DETAILS WILL BECOME A LITTLE MORE CLEAR WITH
NEW HI-RES GUIDANCE.
AFTER THE EXIT OF THIS STORM SYSTEM ON TUESDAY, MEDIUM-RANGE
GUIDANCE CONTINUES TO PREDICT A LONGWAVE TROUGH AND ASSOCIATED
CANADIAN HIGH PRESSURE OVERTAKING MUCH OF THE CENTRAL AND EASTERN
CONUS MID TO LATE WEEK. THIS WILL FAVOR DRIER AND MUCH COOLER
WEATHER. IN FACT, WIDESPREAD SUB-FREEZING TEMPERATURES ARE
FORECAST WEDNESDAY AND THURSDAY NIGHTS. GRADUAL WARMING AND HEIGHT
RISES SHOULD OCCUR INTO THE WEEKEND. LOW TO MEDIUM RAIN CHANCES
THEN RETURN TO THE AREA WITH SOUTHWESTERLY FLOW ALOFT.
