CURRENT SATELLITE AND RADAR SHOWS A BROAD AREA OF CLOUDS AND
LIGHT SHOWERS COVERING A MAJORITY OF THE SE CONUS. THIS IS
SUPPORTED BY ESE FLOW ALONG SURFACE HIGH PRESSURE OFF THE MID
ATLANTIC COAST. THE INDUCED ESE FLOW IS ACTING AS A FAVORABLE
CONVEYOR OF OCEAN MOISTURE INTO THE TN VALLEY. DEW POINTS HAVE
INCREASED TO THE MID TO HIGH 60S AREA WIDE AND BMX 12Z SOUNDING
SHOWS PWATS JUST BELOW 2". DESPITE ALL THE MOISTURE, WE ARE
LACKING ANY FORCING TO PRODUCE HEAVIER RAINFALL OR STORMS. THUS
WE WILL HAVE ANOTHER BENIGN, IF DREARY, START TO THE WEEK. LOW
CLOUDS AND LIGHT SHOWERS WILL LINGER THROUGH A MAJORITY OF THE
DAY, LIMITING TEMPS TO THE HIGH 70S TO LOW 80S.
CONDITIONS WON'T CHANGE MUCH AS WE HEAD INTO THE OVERNIGHT HOUR.
CLOUDY SKIES AND HIGH DEW POINTS WILL PREVENT US FROM COOLING OFF
TOO MUCH WITH MUGGY LOWS IN THE HIGH 60S PRESENT AT DAY BREAK
TOMORROW.
SHORT TERM
(TUESDAY THROUGH THURSDAY)
ISSUED AT 1016 AM CDT MON OCT 6 2025
UNFORTUNATELY TUESDAY WILL BE ANOTHER DREARY DAY HOWEVER AN
APPROACHING COLD FRONT WILL PROVIDE ENOUGH SUPPORT FOR HEAVIER
RAIN AND PERHAPS A FEW STORMS. THE APPROACHING FRONT, CURRENTLY
DRAPED ACROSS THE PLAINS, LOOKS TO MOVE THROUGH THE TN VALLEY
OVERNIGHT FROM TUESDAY INTO WEDNESDAY. ALONG AND AHEAD OF THIS
FRONT, RAIN CHANCES WILL INCREASE THROUGH THE DAY. THE AMPLE
MOISTURE PRESENT FROM PREVIOUS DAYS OF ESE FLOW WILL SUPPORT
PERIODS OF MODERATE TO HEAVY RAINFALL HOWEVER HIRES MODEL
GUIDANCE MAINTAINS OUR OVERALL QPF NEAR OR JUST ABOVE AN INCH,
HIGHEST IN NW AL. THUS, WE ARE NOT ANTICIPATING ANY MAJOR FLOODING
CONCERNS. AS THE FRONT APPROACHES INSTABILITY WILL ALSO INCREASE
FROM THE SW. A FEW HUNDRED J/KG OF CAPE LOOKS LIKELY TOMORROW
AFTERNOON. WITH THE BETTER SHEAR RETAINING CLOSE PROXIMITY TO THE
FRONT, THIS WILL CREATE A NARROW WINDOW TOMORROW EVENING WHERE
FAVORABLE SHEAR AND CAPE MAY OVERLAP TO PRODUCE SOME STRONGER
STORMS WITH HEAVY RAINFALL FROM CONVECTIVE RAIN RATES AND GUSTY
WINDS BEING THE MAIN CONCERN. INSTABILITY WILL DECREASE WITHIN A
FEW HOURS OF SUNSET DECREASING THE CONCERN FOR ANY STRONGER STORMS
OVERNIGHT.
HIRES MODELS SHOW A MAJORITY OF THE PRECIP ENDING WITH THE
PROGRESSION OF THE FRONT TO OUR SE BY WEDNESDAY MORNING. DESPITE
THIS, CLOUD COVER WILL LIKELY REMAIN FOR MOST OF THE DAY. THE
COMBO OF CLOUDY CONDITIONS AND NORTHERLY WINDS BRINING IN COOLER
AIR WILL MODERATE TEMPERATURES ON WEDNESDAY WITH HIGHS NEAR 80.
WE WILL REMAIN IN CLOSE ENOUGH PROXIMITY TO RETAIN PARTLY TO
MOSTLY CLOUDY SKIES ON THURSDAY, ESPECIALLY IN NE AL. FORTUNATELY
ONLY LOW (~10%) RAIN CHANCES WILL BE PRESENT ON THURSDAY, HOWEVER
THIS COULD INCREASE ESPECIALLY IN NE AL IF THE FRONT SLOWS DOWN.
CLOUDS WILL AGAIN HELP TO MODERATE TEMPERATES WITH HIGHS NEAR
NORMAL IN MID TO HIGH 70S.
LONG TERM
(THURSDAY THROUGH SUNDAY)
ISSUED AT 920 PM CDT SUN OCT 5 2025
CONSENSUS GUIDANCE FROM THE LATEST SUITE OF GLOBAL MODELS
SUGGESTS THAT AN INITIALLY WEAK MID-LEVEL SHORTWAVE DISTURBANCE IN
WNW FLOW ALOFT WILL GRADUALLY DEVELOP INTO A STRONGER TROUGH
ACROSS THE SOUTHEASTERN CONUS OVER THE COURSE OF THE LONG TERM
PERIOD. ALTHOUGH WE WILL LIKELY REMAIN ON THE DRY SIDE OF THE
TROUGH, LOW-LEVEL MOISTURE AND CONVERGENCE WILL BOTH BE SUFFICIENT
FOR A CONTINUATION OF CLOUDS AND A FEW LIGHT SHOWERS ON THURSDAY
AND PERHAPS FRIDAY, AS WELL. HOWEVER, INCREASING DEEP- LAYER
NORTHERLY FLOW (TO THE WEST OF THE MID-LEVEL TROUGH AND A
DEVELOPING AREA OF SURFACE LOW PRESSURE OFF THE SOUTHEASTERN
ATLANTIC COAST) WILL EVENTUALLY ADVECT A DRIER AIRMASS INTO THE
REGION SATURDAY/SUNDAY, WITH ONLY A FEW SHOWERS POSSIBLE IN THE
HIGHER TERRAIN TO OUR NORTHEAST. THROUGH THE PERIOD, HIGHS WILL BE
IN THE M-U 70S, WITH LOWS IN THE 50S.
AVIATION
(18Z TAFS)
ISSUED AT 1201 PM CDT MON OCT 6 2025
MVFR CEILINGS WILL BE IN PLACE AT BOTH TERMINALS AT THE START OF
THE PERIOD. CEILINGS LOOK TO LIFT TO VFR LATE IN THE AFTERNOON
AND REMAIN SO THROUGH THE NIGHT. GUSTY ESE WINDS WILL ALSO BE
PRESENT THROUGH THE TAF WITH HIGHEST GUSTS NEAR 20 KTS AT THE
START OF THE PERIOD, DECREASING SLIGHTLY TO AROUND 15 KTS LATER
THIS EVENING. A PASSING COLD FRONT TOMORROW WILL CREATE
COMPLICATED TAFS AFTER 12Z WITH LOW CEILINGS AND RAIN FOR A
MAJORITY OF THE DAY. CURRENT FORECAST HAS IFR TO MVFR CEILINGS
ARRIVING AROUND SUNRISE WITH LIGHT SHOWERS POSSIBLE. HEAVIEST RAIN
AND LOWEST CEILINGS LOOK TO BE BEYOND THIS TAF PERIOD AND WILL BE
ADDRESSED IN FUTURE TAF ISSUANCE.
