(TONIGHT)
ISSUED AT 651 PM CDT TUE OCT 7 2025
THE TEMPERATURE FORECAST REMAINS ON TRACK AS U70S OVERSPREAD MUCH OF
NORTHERN AL AND SOUTHERN MIDDLE TN. MULTIPLE SURFACE CONVERGENCE
BOUNDARIES AHEAD OF THE MAIN COLD FRONT CONTINUE TO SPROUT SCATTERED
LIGHT TO MODERATE RAIN ACROSS WESTERN PORTIONS OF THE FORECAST
REGION, AND ARE EXPECTED TO CONTINUE ADVANCING EASTWARD THROUGHOUT
THE AFTERNOON. DURING THE LATE AFTERNOON INTO OVERNIGHT PERIOD AN
ABUNDANCE OF CLOUD COVER SHOULD CONTINUE AS THE MAIN COLD FRONT
ADVANCES THROUGH THE AREA, BRINGING MODERATE CHANCES OF
PRECIPITATION (POPS 50%-60%) FOR MOST OF THE FORECAST AREA.
PERSISTING CLOUD COVER WILL ALLOW LOW TEMPERATURES TO REMAIN MILD
IN THE M60S-U60S AS PRECIPITATION ENDS EARLY TOMORROW MORNING.
SHORT TERM
(WEDNESDAY THROUGH THURSDAY NIGHT)
ISSUED AT 651 PM CDT TUE OCT 7 2025
A COOLER AND DRIER AIRMASS BEGINS TO ADVECT IN FROM THE NORTHWEST
IN THE WAKE OF A PASSING COLD FRONT. AS A RESULT, THE SHORT TERM
FORECAST PERIOD WILL FEEL LIKE FALL WITH AFTERNOON HIGHS WED IN
THE MID TO UPPER 70S AND THU IN THE LOW TO MID 70S. OVERNIGHT LOWS
WILL FEEL REFRESHING IN THE LOW TO MID 50S. BIGGEST WEATHER
CONCERN DURING THIS PERIOD IS AN INCREASE IN GRADIENT WINDS IN
BETWEEN THE HIGH ACROSS THE MIDWEST AND THE TROUGH ACROSS THE EAST
COAST. WINDS WED AFTERNOON ARE FORECAST TO GUST 20-25 MPH BEFORE
DIMINISHING IN THE EVENING. OTHERWISE, ENJOY THE FALL WEATHER.
LONG TERM
(FRIDAY THROUGH MONDAY)
ISSUED AT 651 PM CDT TUE OCT 7 2025
DATA FROM THE LATEST SUITE OF GLOBAL MODELS CONTINUES TO SUGGEST
THAT A MID-LEVEL TROUGH (INITIALLY ACROSS GA/SC) WILL EVOLVE INTO
A RATHER DEEP CLOSED LOW AS IT DRIFTS NORTHEASTWARD IN THE GENERAL
VICINITY OF THE SOUTHEASTERN ATLANTIC COAST OVER THE COURSE OF
THE LONG TERM PERIOD. ALTHOUGH THIS DEVELOPMENT WILL OCCUR IN
RESPONSE TO AN INTENSE HIGH-LEVEL SPEED MAX DIGGING SOUTH-
SOUTHEASTWARD THROUGH OUR REGION THIS WEEKEND, IT STILL APPEARS AS
IF OUR FORECAST AREA WILL REMAIN ON THE DRY/WESTERN SIDE OF THE
LOW, WITH LITTLE TO NO OPPORTUNITY FOR ADDITIONAL RAINFALL (ASIDE
FROM A FEW AFTERNOON SHOWERS ALONG THE CUMBERLAND PLATEAU ON
FRIDAY). HIGHS WILL SLOWLY WARM FROM THE L-M 70S ON FRIDAY INTO
THE U70S-L80S BY MONDAY, WITH PLEASANTLY COOL OVERNIGHT LOWS IN
THE U40S-L50S.
AVIATION
(00Z TAFS)
ISSUED AT 703 PM CDT TUE OCT 7 2025
A BROKEN BAND OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
PROGRESS SOUTHEASTWARD AND AWAY FROM THE TERMINALS EARLY THIS
EVENING, IN CONJUNCTION WITH AN INITIAL PREFRONTAL SFC TROUGH.
ALTHOUGH REDEVELOPMENT OF A FEW ADDITIONAL LGT SHRA COULD OCCUR AS
A SECOND (AND MORE PRONOUNCED) SFC TROUGH TRACKS SOUTHEASTWARD
LATER THIS EVENING AND INTO THE EARLY MORNING HOURS WED, THIS
ACTIVITY WOULD LIKELY BE CONCENTRATED TO THE S/E OF HSV, AND WE
WILL NOT MENTION ANY PRECIP IN THE TAFS ATTM. AS RESIDUAL MID-
LEVEL CLOUDS SCATTER, CONDITIONS MAY BECOME FAVORABLE FOR THE
DEVELOPMENT OF BR/FG EARLY TOMORROW MORNING GIVEN COVERAGE OF
WETTING RAINFALL TODAY, HIGH BOUNDARY LAYER RH AND LGT/VRBL TO LGT
NORTHERLY WINDS. NORTH-NORTHEASTERLY GRADIENT WINDS WILL
STRENGTHEN BTWN 12-15Z, WITH A BROKEN LAYER OF LOW-VFR STRATUS
EXPECTED TO PERSIST FOR THE REMAINDER OF THE PERIOD.
