KEY MESSAGES
UPDATED AT 843 PM CDT WED SEP 23 2026
- A COOLER AND DRIER AIRMASS WILL FILTER INTO THE REGION THROUGH
THE WEEKEND. HIGHS WILL FALL INTO THE LOWER-MID 80S WITH LOWS
IN THE MID 50S-LOWER 60S THURSDAY THROUGH SUNDAY.
NEAR TERM
(REST OF TONIGHT AND THURSDAY)
ISSUED AT 843 PM CDT WED SEP 23 2026
CONVECTION LARGELY STAYED JUST TO OUR EAST THIS EVENING, ALLOWING
FOR OVERALL DRY CONDITIONS THROUGH THE TENNESSEE VALLEY. CAMS
INDICATE THIS WILL BE A COPY AND PASTE FORECAST FOR THURSDAY, WITH
CONVECTION REMAINING JUST ON OUR EASTERN BORDER REGION AS THE
TENNESSEE VALLEY REMAINS WEDGED BETWEEN AN APPROACHING UPPER LEVEL
RIDGE AND A DEPARTING UPPER LEVEL TROUGH (AND SUBSEQUENT SFC LOW)
SHIFTING NORTHEASTWARD. OVERNIGHT, LOW STRATUS SHOULD CONTINUE TO
BLANKET THE AREA, WHICH SHOULD PREVENT WIDESPREAD FOG FORMATION.
HOWEVER, IN AREAS OF HIGHER ELEVATION, THERE WILL LIKELY BE
VISIBILITY ISSUES AS LOW CLOUDS LINGER THROUGH THE AREA DURING THE
MORNING COMMUTE. USE CAUTION WHILE DRIVING! LOWS ARE FORECAST TO
DROP INTO THE LOW TO MID 60S.
SHORT TERM
(THURSDAY NIGHT THROUGH SATURDAY)
ISSUED AT 843 PM CDT WED SEP 23 2026
DRY WEATHER IS IN STORE FOR US AS THE AFOREMENTIONED UPPER LEVEL
RIDGE CONTINUES ITS JOURNEY EASTWARD, BRINGING SUBSEQUENT HIGH
PRESSURE TO THE AREA. HIGH TEMPERATURES ARE FORECAST TO BE
RELATIVELY COOLER TO WHAT WE'VE BEEN EXPERIENCING LATELY-
REMAINING CAPPED IN THE UPPER 70S TO MID 80S. OVERNIGHT LOWS
DURING THIS TIME ARE FORECAST TO DROP INTO THE 50S FOR THE
MAJORITY OF THE AREA. THESE TEMPERATURES ARE ON PAR WITH
CLIMATOLOGICAL NORMS FOR THIS TIME OF YEAR, WHICH ARE HIGHS IN
THE LOW 80S AND LOWS IN THE UPPER 50S.
LONG TERM
(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 843 PM CDT WED SEP 23 2026
THROUGH THE LONG TERM FORECAST, MID LEVEL RIDGING TO OUR SOUTHWEST
WILL DAMPEN, KEEPING TROUGHING TO OUR EAST AS THE PRIMARY INFLUENCE
FOR LOCAL WEATHER. THE DAMPENING RIDGE PAIRED WITH PERSISTENT
TROUGHING ALONG THE EAST COAST WILL MAINTAIN NORTHWEST FLOW ALOFT
THROUGH THE PERIOD. THIS WILL MAINTAIN OUR COOLER AND DRIER AIRMASS
WITH TEMPERATURES REMAINING IN THE MID TO HIGH 80S EACH DAY. THE NEXT
FEATURE OF INTEREST LOOKS TO ARRIVE AT THE END OF THE LONG TERM IN
THE FORM OF A PASSING MID LEVEL TROUGH AND ASSOCIATED SURFACE COLD
FRONT. ALONG AND AHEAD OF THIS FRONT, LIGHT SOUTHERLY SURFACE FLOW
LOOKS TO INDUCE SOME WEAK RETURN FLOW WHICH MAY ALLOW US TO BRIEFLY
BREAK BACK INTO THE 90S ON TUESDAY, THIS HOWEVER IS CONTINGENT ON THE
ACTUAL TIMING OF THE FRONT. IF THE FRONT SPEEDS UP, ASSOCIATED CLOUD
COVER AND SLIGHT INCREASES IN RAIN CHANCES MAY KEEP HIGHS ON TUESDAY
BELOW 90. CURRENTLY KEPT BLENDED GUIDANCE FOR RAIN CHANCES, WHICH
SUPPORT THE FRONT PASSING THROUGH ON WEDNESDAY WITH HIGHEST RAIN
CHANCES WEDNESDAY AFTERNOON. WITH THIS BEING ABOUT A WEEK OUT, TIMING
AND IMPACTS FROM THE FRONT ARE LIKELY TO CHANGE, PLEASE CHECK BACK
FOR UPDATES.
AVIATION
(06Z TAFS)
ISSUED AT 1252 AM CDT THU SEP 24 2026
A STRATUS CLOUD DECK IS MOVING INTO THE REGION FROM THE EAST,
BRINGING LOWER CIGS (MVFR TO IFR) ALONG WITH IT. EXPECTING THESE
CLOUDS TO CONTINUE TO OVERSPREAD NORTH ALABAMA OVER THE NEXT FEW
HOURS. IFR CIGS ARE FORECAST TO DEVELOP FOR BOTH TERMINALS AROUND
12Z, WITH CONDITIONS IMPROVING SLIGHTLY TO MVFR BY MID-MORNING. WE
WILL BE MONITORING HOW LONG THE LOW CLOUDS LINGER THROUGH THE
DAY; BUT, FOR NOW, WE ARE FORECASTING THAT CLOUDS WILL BEGIN TO
BREAK UP FROM EARLY TO MID-AFTERNOON (VFR CONDITIONS RETURNING).
OTHERWISE, LITTLE TO NO RAIN IS EXPECTED TODAY (WILL MAINLY BE TO
OUR NORTHEAST). IN ADDITION, NORTHEASTERLY WINDS OVERNIGHT WILL
GRADUALLY BECOME EASTERLY THROUGH THE DAY BUT REMAIN AROUND 5
KNOTS OR LESS.
