ISSUED AT 1029 AM CST WED MAR 4 2026
HIGH PRESSURE TO THE SOUTHEAST WILL REMAIN THE PRIMARY WEATHER
INFLUENCE ACROSS THE TENNESSEE VALLEY ON THURSDAY. BREEZY
SOUTHWEST WINDS AND AMPLE SUNSHINE WILL HELP TEMPERATURES MAKE A
RUN AT HIGH A RECORD HIGH LEVELS -- INTO THE LOWER 80S IN MOST
LOCATIONS. CLOUD COVER WILL INCREASE AHEAD OF A SHORTWAVE TROUGH
THURSDAY NIGHT INTO FRIDAY. DEEP SOUTHWESTERLY FLOW WILL CONTINUE
TO ADVECT IN A WARM, MOIST AIR MASS FROM THE GULF REGION. STRONGER
LIFT AHEAD OF THIS SHORTWAVE WILL HELP TO CREATE LOW TO MEDIUM
(30-50%) CHANCES FOR SHOWERS AND A FEW THUNDERSTORMS DURING THE
AFTERNOON. DESPITE THE CONVECTION, HIGHS WILL STILL FLIRT WITH
RECORD HIGH LEVELS IN THE LOWER 80S. INITIAL CONVECTION WILL
LARGELY WANE FRIDAY EVENING/NIGHT. HOWEVER, MUCH HIGHER CHANCES
FOR SHOWERS AND STORMS (50-80%) ARE FORECAST DURING THE DAY ON
SATURDAY, WITH THE ARRIVAL OF A COLD FRONT. GIVEN PWATS AROUND
1.3", LOCALLY HEAVY DOWNPOURS WILL BE A CONCERN WITH THIS
ACTIVITY. WIND SHEAR WILL BE PRETTY MODEST FOR THIS EVENT, WITH
BULK SHEAR VALUES AROUND 25 KTS. HOWEVER, IF CONVECTION CAN HOLD
OFF UNTIL THE AFTERNOON AND EVENING, SOME MODEST SURFACE-BASED
INSTABILITY COULD RESULT IN A FEW MORE ROBUST UPDRAFTS AND A
COUPLE LOCALLY STRONGER STORMS.
SOME RECORD HIGH TEMPERATURES FOR THURSDAY AND FRIDAY

LONG TERM
(SATURDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1001 PM CST TUE MAR 3 2026
THIS WEEKEND WILL BE UNSEASONABLY WARM WITH MULTIPLE ROUNDS OF
RAINFALL AND SOME THUNDERSTORMS. THE SFC LOW UP IN THE GREAT LAKES
WILL CONTINUE TO SLOWLY PULL THE ASSOCIATED COLD FRONT SOUTHEASTWARD
ON SATURDAY. AHEAD OF THIS FRONT, WARM, TROPICAL AIR WILL STREAM INTO
THE REGION SETTING UP FOR HEAVY RAINFALL AND WITH SOME THUNDERSTORMS
TO OCCUR AHEAD OF THE FRONT. POPS WILL INCREASE THROUGHOUT THE DAY
FROM WEST TO EAST ON SATURDAY (70-80%) AND DESPITE THE CONVECTION
AND CLOUD COVER, BREEZY SOUTHERLY WINDS WILL PUSH DAYTIME HIGHS INTO
THE LOWER 80S. THIS COULD TIE OR BREAK A RECORD TEMP. THE FRONT WILL
WEAKEN AS IT HEADS INTO THE TN VALLEY SATURDAY NIGHT, BUT THE MODELS
ARE UNCERTAIN ON EXACTLY WHERE IT WILL STALL OUT. POPS WILL DIP IN
COVERAGE SATURDAY NIGHT BUT PICK BACK UP ON SUNDAY TO HIGH CHANCES
(70%) AS A DISTURBANCE RIDES ACROSS THIS STALLED OUT FRONT. HIGHS
WILL BE A TAD COOLER BUT STILL ABOVE SEASONAL NORMS ON SUNDAY, ONLY
REACHING THE LOW TO MID 70S. THE UNSEASONABLE WARMTH AND THE
UNSETTLED PATTERN WILL KEEP THE CHANCE FOR SHOWERS AND A FEW STORMS
IN THE FORECAST INTO EARLY NEXT WEEK.
