THE PASSAGE OF A DRY FRONT CAN EASILY BE SEEN ON SATELLITE AND
SURFACE OBSERVATIONS. ON SATELLITE, A THIN BAND OF CLOUDS CAN BE
SEEN EXITING OUR CWA. ON SURFACE OBSERVATIONS, WINDS HAVE BACKED
TO THE NORTH WITH MUCH COOLER AIR BEING USHERED IN BEHIND THE
FRONT. CURRENTLY, TEMPERATURES RANGE FROM THE LOW 50S IN TN TO THE
60S CLOSER TO THE FRONT IN CULLMAN AND DEKALB.
THE PASSAGE OF THE FRONT WILL SIGNIFICANTLY MODERATE TEMPERATURES
AND DEW POINTS TODAY KEEPING THING SEVERAL DEGREES COOLER. HIGHS
ARE FORECAST IN THE UPPER 60S WITH DEWPOINTS DROPPING INTO THE 30S
AND 40S. THE COOLER AND DRIER AIRMASS WILL CARRY INTO THE NIGHT

SHORT TERM
(TUESDAY THROUGH THURSDAY)
ISSUED AT 922 AM CDT MON MAR 23 2026
SURFACE HIGH PRESSURE WILL BUILD IN THE CENTRAL PLAINS AND
TRANSITION EAST THROUGH THE OHIO VALLEY THROUGH WEDNESDAY. THIS
WILL MAINTAIN NNE SURFACE FLOW AND MAINTAIN OUR RELATIVELY COOLER
TEMPERATURES WITH TEMPS FORECAST IN THE UPPER 60S ON TUESDAY TO
LOWER 70S ON WEDNESDAY. AS THE SURFACE HIGH PUSHES OFF THE
ATLANTIC COAST, SSE FLOW WILL DEVELOP ALONG THE BACKSIDE OF THE
HIGH SUPPORTING A GRADUAL WARMING IN TEMPS THROUGH THE END OF THE
WEEK. THIS WILL BE APPARENT ON THURSDAY AS TEMPS RISE INTO THE LOW
80S.
DESPITE THE WARMING TEMPS, AN UPPER LEVEL SHORT WAVE WILL SUPPORT
AN INCREASE IN CLOUD COVER AND LOW RAIN CHANCES FROM TUESDAY
AFTERNOON INTO WEDNESDAY. ANY SHOWERS THE DO DEVELOP WILL LIKELY
BE SCATTERED IN NATURE WITH NO SEVERE THREAT ASSOCIATED WITH THEM.
LONG TERM
(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 923 PM CDT SUN MAR 22 2026
A STRONG 5H ANTICYCLONE OVER TX WILL REMAIN IN PLACE THROUGH THIS
PERIOD WITH A RIDGE AXIS ACROSS THE GULF STATES. THE RIDGE WILL
FLATTEN JUST ENOUGH TO ALLOW A COLD FRONT TO DROP INTO THE REGION ON
FRIDAY AS A STRONG SURFACE HIGH BUILDS SOUTHEAST INTO THE LOWER MO
AND MIDDLE MS VALLEY. THE MODELS INDICATE THAT PRECIPITATION WILL BE
ANAFRONTAL IN NATURE, AND WILL DIMINISH SIGNIFICANTLY FRIDAY NIGHT AS
LARGE PRESSURE RISES ENTER THE REGION. SO FOR NOW, ONLY LOW CHANCES
OF -SHRA ARE IN THE FORECAST FRIDAY NIGHT. AFTER HIGHS IN THE LOWER
TO MIDDLE 80S THURSDAY, READINGS WILL FALL THROUGH THE DAY INTO THE
UPPER 60S TO LOWER 70S BY LATE AFTERNOON FRIDAY. LOWS IN THE UPPER
30S TO AROUND 40 ARE EXPECTED SATURDAY AND SUNDAY MORNINGS. HIGHS ON
SATURDAY WILL BE IN THE LOWER TO MIDDLE 60S, BUT RECOVER INTO THE
UPPER 60S TO LOWER 70S ON SUNDAY AS THE SURFACE HIGH PUSHES TO THE
MID ATLANTIC COAST AND THE 8H HIGH SHIFTS INTO GA.
AVIATION
(12Z TAFS)
ISSUED AT 643 AM CDT MON MAR 23 2026
THERE HAVE BEEN NO SIGNIFICANT CHANGES TO PREVIOUS AVIATION
FORECAST REASONING, AS LATEST SATELLITE IMAGERY SUGGESTS THAT LOW
STRATUS CLOUDS WILL CONTINUE TO BUILD INTO THE REGION IN THE WAKE
OF A COLD FRONT. ALTHOUGH A FEW SPRINKLES OF RAIN MAY ALSO OCCUR
THROUGH MID/LATE MORNING, PRECIP CHANCES ARE TOO LOW TO MENTION IN
THE TAFS. AFTER LOW CLOUDS MIX OUT (16-17Z), VFR CONDITIONS WILL
RETURN WITH A NORTH FLOW OF 10G18 KTS VEERING TO NNE THIS EVENING.
A BKN-OVC LAYER OF CS WILL RETURN AROUND SUNSET IN ADVANCE OF AN
UPPER-LVL DISTURBANCE DIGGING SOUTHEASTWARD OVER THE CENTRAL
PLAINS.
