UPDATED AT 1200 PM CDT FRI JUL 11 2025
- RAIN AND THUNDERSTORM CHANCES CONTINUE THROUGH THE WEEKEND, BEST

SHORT TERM
(REST OF TODAY THROUGH SATURDAY)
ISSUED AT 1200 PM CDT FRI JUL 11 2025
SATELLITE AND RADAR OBSERVATIONS ARE BECOMING A LITTLE BUSY AROUND
NOON CURRENTLY, WITH PWS ABOVE 1.5" ALONG AND SOUTH OF I-40.
SCATTERED SHOWERS AND THUNDERSTORMS ARE FORECAST IN THIS AREA,
WITH MORE ISOLATED COVERAGE NORTHWARD. OTHERWISE, A PRETTY TYPICAL
SUMMER DAY IS IN STORE WITH HIGH IN THE UPPER 80S TO LOWER 90S AND
A LIGHT SOUTHWESTERLY BREEZE. BRIEF HEAVY DOWNPOURS, GUSTY WINDS,
AND FREQUENT LIGHTNING ARE POSSIBLE IN ISOLATED STRONGER STORMS
THROUGH THE AFTERNOON.
RELATIVELY CALM OVERNIGHT CONDITIONS ARE FORECAST ACROSS MIDDLE TN
WITH PATCHY FOG POSSIBLE IN THE USUAL LOCATIONS. LOWS IN THE LOW
TO MID 70S ARE FORECAST, WITH COOLER TEMPS (UPPER 60S) OVER THE
PLATEAU.
FOR TOMORROW, SHOWERS AND THUNDERSTORMS APPEAR TO BE MORE NUMEROUS
AS PWS INCREASE AREA-WIDE DUE TO AN INCREASE IN SOUTHWESTERLY
LOW-LEVEL FLOW AHEAD OF A SYSTEM TO OUR NORTHWEST. WHILE WE ONLY
GET A GLANCING BLOW FROM THE DEPARTING SHORTWAVE TO THE NORTH,
THERE'S ENOUGH EXTRA FORCING TO INDICATE BETTER COVERAGE AND
PERHAPS SOME MULTICELL CLUSTERS AND COLD POOLING DURING THE
AFTERNOON. NO ORGANIZED SEVERE WEATHER IS EXPECTED AT THIS TIME,
WHICH IS MAINLY INHIBITED BY POOR MID-LEVEL LAPSE RATES AND <15
KTS EFFECTIVE BULK SHEAR.
LONG TERM
(SATURDAY NIGHT THROUGH NEXT FRIDAY)
ISSUED AT 1139 AM CDT FRI JUL 11 2025
MIDDLE TENNESSEE WILL REMAIN IN A FAVORABLE ZONE FOR CONTINUED
RAIN CHANCES THROUGH THE LONG-TERM FORECAST. SUNDAY COULD ONCE
AGAIN BE AN AFTERNOON OF SCATTERED TO NUMEROUS SHOWERS AND STORMS
WITH ENHANCED MOISTURE VALUES REMAINING IN THE AREA NEAR AHEAD OF
THE STALLING, DIFFUSE FRONT TO OUR NORTH, AS WELL AS THE APPROACH
OF A WEAKENING SHORTWAVE DISTURBANCE ALOFT. WE'LL SEE SIMILAR
IMPACTS WITH ISOLATED STRONGER STORMS, AND PERHAPS, SOME
LOCALIZED FLOODING WHERE ANY TRAINING SHOULD OCCUR.
NEXT WEEK FAVORS A SLIGHTLY ABOVE AVERAGE TEMPERATURE TREND AS
RIDGING STRENGTHENS ACROSS THE REGION. HIGHS WILL BE THE MID 90S
FOR NASHVILLE AND SURROUNDING AREAS BY MID WEEK. HOWEVER, WE'LL
CONTINUE TO BE PLAGUED BY HUMID CONDITIONS AND DIURNAL CONVECTION
EACH DAY. AFTERNOON HEAT INDICES EACH DAY SHOULD RANGE IN THE 90S
TO THE LOWER 100S.
AVIATION
(12Z TAFS)
ISSUED AT 603 AM CDT FRI JUL 11 2025
PATCHY FOG THIS MORNING IS RESULTING IN LOCALIZED MVFR CONDITIONS.
THESE CONDITIONS WILL GRADUALLY IMPROVE THROUGH THE MORNING HOURS.
SHOWERS AND THUNDERSTORMS WILL THEN AGAIN DEVELOP THIS AFTERNOON,
BUT COVERAGE WILL LIKELY BE LESS COMPARED TO RECENT DAYS. ANY
STORMS WILL DIMINISH AROUND 00Z-02Z. PATCHY FOG LIKELY REDEVELOPS
OVERNIGHT WITH HIGHEST CONFIDENCE AT KCSV AND KSRB.
