THE BACKDOOR COLD FRONT IS CONTINUING TO MOVE WEST ACROSS THE
AREA. AT THE SURFACE, IT HAS BROUGHT A LAYER OF COOLER AND DRIER
AIR INTO NE AL WHICH IS ONE OF THE MAIN REASONS WE HAVE YET TO SEE
ANY SIGNIFICANT COVERAGE OR INTENSITY OF RAINFALL TODAY. THIS
SLIGHTLY DRIER TREND WILL CONTINUE THROUGH THE REMAINDER OF THE
DAY.
THE ATTACHED STRATUS IS SLOWLY ERODING FROM WEST TO EAST WITH
I-65 CURRENTLY SERVING AS A DIVIDER BETWEEN OVERCAST CONDITIONS TO
THE EAST AND A FAIR WEATHER CU FIELD TO THE WEST. THIS HAS LEAD
TO A 10+ DEGREE TEMPERATURE GRADIENT FROM NW AL IN THE LOW TO MID
80S TO NE AL IN THE LOW TO MID 70S. THE CLOUD DECK IS FORECAST TO
REMAIN OVERNIGHT. EVEN SO, TEMPS WILL DROP DOWN INTO THE MID TO
HIGH 60S MAKING FOR A VERY COOL AUGUST NIGHT TO START THE SCHOOL
YEAR HERE LOCALLY.
SHORT TERM
(MONDAY THROUGH WEDNESDAY)
ISSUED AT 1033 AM CDT SUN AUG 3 2025
OUR CURRENT MILD PATTERN PRESENT IN THE NEAR TERM FORECAST WILL
EXTEND INTO THE SHORT TERM. WITH SURFACE HIGH PRESSURE REMAINING
ANCHORED OVER THE EASTERN GREAT LAKES, CAD IS SET TO REMAIN IN
PLACE THROUGH MID WEEK. THIS WILL CONTINUE TO PROMOTE ESE FLOW
ALONG THIS REGIME LEADING TO INCREASED CLOUD COVER AND RAIN
CHANCES FOR OUR EASTERN AREAS. WE WILL CONTINUE TO MONITOR FOR
FLOODING CONCERNS EACH DAY BASED ON PREVIOUS RAINFALL RECEIVED.
UNDER INCREASED CLOUD COVER, OUR TEMPERATURE WILL REMAIN 5-10
DEGREES BELOW NORMAL FOR MONDAY AND TUESDAY WITH HIGHS IN THE
UPPER 70S TO LOW 80S. TEMPS WILL WARM UP SLIGHTLY ON WEDNESDAY
INTO THE MID 80S AND INDICATE THE START OF A SLOW WARMING TREND TO
RETURN OUR TEMPERATURES TO NORMAL THROUGH THE REMAINDER OF THE
WEEK.
LONG TERM
(WEDNESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 950 PM CDT SAT AUG 2 2025
A TROUGHING PATTERN CONTROLLING OUR SENSIBLE WEATHER INTO THE MID
WEEK, WILL SLOWLY REVERT BACK TO A RIDGE DOMINATED REGIME AS WE GO
TO THE LATE WEEK. MEAN TROUGHING ALONG THE EASTERN THIRD OF THE
CONUS SHOULD BEGIN RETREATING TO THE NORTH WED, AS UPPER RIDGING
TO OUR SW REAMPLIFIES AND SHIFTS SOMEWHAT MORE TO THE EAST. THIS
RIDGE IN FACT BY THE LATTER HALF OF NEXT WEEK SHOULD HAVE CENTRAL
500MB HEIGHTS AT OR ABOVE 600 DECAMETERS ON THURSDAY, INDICATIVE
OF A VERY HOT CONDITIONS UNDER IT. BUT TOWARDS SAT, MORE OF A
CLOSED UPPER LOW LOOKS TO BE FORMING OVER THE APPALACHIANS, WHILE
THE RIDGING RETREATS SOMEWHAT MORE TO THE WEST.
THIS ALL CONTINUES UNSETTLED WEATHER FOR THE MID AND LATTER
PORTION OF THE WEEK. A CONTINUATION OF MOISTURE SEEPING NORTHWARD
FROM THE GULF WILL KEEP MAINLY AFTERNOON SHOWER AND THUNDERSTORM
CHANCES EACH DAY. AFTER LOW IN THE MID/UPPER 60S TUE NIGHT, HIGHS
ON WED SHOULD RISE INTO THE LOW/MID 80S. A SLOW WARMING TREND IS
EXPECTED THU/FRI WITH HIGHS IN THE MID/UPPER 80S, THEN BACK INTO
THE LOWER 90S BY SAT.
AVIATION
(00Z TAFS)
ISSUED AT 645 PM CDT SUN AUG 3 2025
LOW LEVEL MOISTURE OVERSPREADING THE REGION WILL PRODUCE LOWER
CLOUDS FOR THE TAF. DAYTIME HEATING HAS SCATTERED SOME OF THE
STRATUS DECK OVER THE TENNESSEE VALLEY IN THE AFTERNOON. BUT
TONIGHT, AM EXPECTING MVFR CIGS TO RETURN. THESE CLOUDS AND AN ESE
WIND OF 5-10KT SHOULD PREVENT THE FORMATION OF FOG. ACCORDING TO
GUIDANCE, THE MVFR CIGS SHOULD PERSIST OVER KHSV INTO THE
AFTERNOON MON, BUT SHOULD SCATTER OUT OVER KMSL. THERE WILL BE
LOWER END CHANCES FOR SHOWERS AT KMSL THIS EVENING, BUT CHANCES
ARE TOO LOW FOR INCLUSION IN THE TAF IN THIS ISSUANCE.
