NEAR TERM
(TONIGHT)
ISSUED AT 222 PM CDT MON APR 14 2025
A VERY WARM AFTERNOON ACROSS THE TENNESSEE VALLEY, WITH
TEMPERATURES SURGING INTO THE LOW TO MID 80S. CLOUDS WILL RAPIDLY
INCREASE THIS EVENING AND OVERNIGHT AS A COLD FRONT APPROACHES THE
TENNESSEE VALLEY -- AND EVENTUALLY MOVES INTO THE AREA AFTER
MIDNIGHT. MOISTURE IS SOMEWHAT LIMITED AND FOR THIS REASON ONLY
LOW TO MEDIUM CHANCES (20-40%) OF SHOWERS ARE FORECAST (WITH A
ROGUE STORM OR TWO POSSIBLE AS WELL). LOW CONFIDENCE IN STORMS IS
DUE TO A FAIRLY PRONOUNCED CAPPING INVERSION -- THOUGH SOME WEAK
ELEVATED INSTABILITY MAY ALLOW FOR A FEW RUMBLES OF THUNDER. THIS
ACTIVITY WILL TAPER OFF VERY LATE TONIGHT INTO THE EARLY MORNING
HOURS ON TUESDAY AS DRIER AIR FILTERS IN BEHIND THE COLD FRONT,
WITH TEMPERATURES BOTTOMING OUT IN THE LOW TO MID 50S.
SHORT TERM
(TUESDAY THROUGH WEDNESDAY NIGHT)
ISSUED AT 1035 AM CDT MON APR 14 2025
AFTER THE PASSAGE OF THE AFOREMENTIONED COLD FRONT EARLY TUESDAY
MORNING, COOLER AND DRIER CONDITIONS WILL BE USHERED INTO THE
REGION THROUGH MIDWEEK. NO RAIN IS FORECAST, WITH SKIES MOSTLY
CLEAR THROUGH WEDNESDAY MORNING; ALTHOUGH, SOME UPPER LEVEL CLOUDS
MAY RETURN BY WEDNESDAY AFTERNOON AS MOISTURE BEGINS TO GRADUALLY
INCREASE THROUGH LATE WEEK. OTHER THAN SOME BREEZY CONDITIONS
WITH GUSTS TO AROUND 20 MPH ON TUESDAY, NO IMPACTFUL WEATHER IS
ANTICIPATED. HIGHS ARE FORECAST TO TOP OUT IN THE 60S BOTH DAYS;
ALTHOUGH, SOME LOCATIONS OVER NW AL MAY REACH CLOSER TO 70 DEGREES
ON WEDNESDAY. LOWS WILL THEN DIP INTO THE 40S TUESDAY NIGHT AND
WEDNESDAY NIGHT.
LONG TERM
(THURSDAY THROUGH SUNDAY)
ISSUED AT 1047 PM CDT SUN APR 13 2025
THE UPPER LEVEL RIDGING CONTINUES TO BUILD OVER THE AREA INTO THE
END OF THIS UPCOMING WEEK. SEVERAL DISTURBANCES WILL PASS WELL TO
OUR NORTH THROUGH THE OHIO VALLEY REGION DURING THIS TIME.
TEMPERATURES SHOULD WARM MORE SIGNIFICANTLY AS A RESULT WITH HIGHS
CLIMBING BACK INTO THE UPPER 70S TO LOWER 80S AT LEAST. LOWS
SHOULD CLIMB BACK INTO THE 50S AND LOWER 60S. A DRY FORECAST
THOUGH, SO A NICE TIME TO ENJOY OUTDOOR PLANS.
THE UPPER LEVEL RIDGING WEAKENS BUT REMAINS OVER THE SOUTHEAST
INTO NEXT WEEKEND. WE COULD SEE SOME SHOWERS APPROACH THE AREA
TOWARDS THE END OF THE WEEKEND. A MORE SIGNIFICANT STORM SYSTEM
MAY MATERIALIZE JUST BEYOND THAT PERIOD.
AVIATION
(00Z TAFS)
ISSUED AT 701 PM CDT MON APR 14 2025
MODERATELY STRONG SW FLOW OF 10G18 KTS WILL CONTINUE AT THE
HSV/MSL AIRPORTS THIS EVENING, WITH A NOTABLE INCREASE IN MAINLY
MID AND HIGH-LVL CLOUDS EXPECTED OVER THE NEXT 4 HRS. TO THE
NORTHWEST OF THE LOCAL AREA, WEAK CONVECTIVE SHOWERS WILL CONTINUE
TO DEVELOP SOUTHWESTWARD ALONG A SOUTHEASTWARD-MOVING COLD FRONT
(CURRENTLY ACROSS SOUTHWESTERN KY/NORTHWESTERN TN). ALTHOUGH THE
GREATEST COVERAGE OF THUNDERSTORMS WILL LIKELY REMAIN FROM THE
UPPER CUMBERLAND PLATEAU EAST-NORTHEASTWARD, A NARROW BAND OF
SHOWERS WILL LIKELY IMPACT MSL/5-7Z AND HSV/6-8Z AS THE FRONT
CROSSES THE TERMINALS. HOWEVER, A LAYER OF STRATUS WILL DEVELOP
PRIOR TO FROPA, WITH CIGS PERHAPS AS LOW AS 3500 FT POSSIBLE BTWN
4-10Z. SKIES WILL CLEAR RATHER QUICKLY AROUND SUNRISE TUE MORNING,
WITH NW FLOW OF 10G18 KTS ANTICIPATED THROUGHOUT THE AFTERNOON
HOURS.
