NEAR TERM
(REST OF TONIGHT AND SUNDAY)
ISSUED AT 941 PM CDT SAT AUG 23 2025
A COUPLE CLUSTERS OF SHOWERS AND STORMS WILL PERSIST THROUGH
AROUND MIDNIGHT OR SO ALONG RESIDUAL OUTFLOW BOUNDARIES, BUT THE
GENERAL TREND HAS BEEN THIS ACTIVITY DIMINISHING AS THE BOUNDARY
LAYER STABILIZES. THUS, OUTSIDE OF A ROGUE SHOWER/STORM
OVERNIGHT, MOST LOCATIONS WILL REMAIN DRY AS THE SKY CLEARS. SOME
LOCALIZED PATCHY FOG WILL BE POSSIBLE EARLY SUNDAY MORNING DUE TO
THE MOSTLY CLEAR/CALM CONDITIONS AND THE MOIST BOUNDARY LAYER FROM
EARLIER RAINFALL. OTHERWISE A WARM/HUMID NIGHT WITH LOWS IN THE
UPPER 60S TO LOWER 70S.
A SHORTWAVE/SURFACE TROUGH WILL SWING THROUGH THE TENNESSEE
VALLEY DURING THE DAY ON SUNDAY, BRINGING SOME LOW CHANCES
(20-30%) FOR A SHOWERS AND STORMS ONCE AGAIN IN THE AFTERNOON. THE
MAIN STORY WILL BE THE AIR MASS CHANGE THAT WILL FOLLOW THE FRONT
(MORE ON THIS IN THE SECTION BELOW) WHICH WILL BE NOTICEABLE BY
SUNDAY EVENING. DURING THE DAY ON SUNDAY HOWEVER, EXPECT MOSTLY
SUNNY CONDITIONS ONCE AGAIN AND HIGHS AT SEASONABLE LEVELS IN THE
UPPER 80S TO LOWER 90S IN MOST LOCATIONS.
SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY)
ISSUED AT 941 PM CDT SAT AUG 23 2025
AS MENTIONED IN THE SECTION ABOVE, A VERY NOTABLE AIR MASS CHANGE
WILL TAKE PLACE EARLY NEXT WEEK IN WAKE OF A COLD FRONT AS AN
UNSEASONABLY COOL/DRY AIR MASS WILL MOVE INTO THE REGION. THIS
WILL NOTICEABLE BY SUNDAY EVENING/NIGHT, AS DEWPOINTS DROP INTO
THE MID 50S -- ALLOWING LOW TEMPERATURES TO DROP BELOW THE 60
DEGREE MARK ACROSS SOUTHERN MIDDLE TENNESSEE AND THE LOWER 60S
ACROSS NORTHERN ALABAMA. MOSTLY SUNNY AND DRY CONDITIONS ON MONDAY
WILL MAKE FOR A BEAUTIFUL DAY (HIGHS IN THE LOW TO MID 80S), WITH
LOWER RH VALUES MAKING IT FEEL QUITE COMFORTABLE. ANOTHER
SHORTWAVE WILL CLIP THE AREA MONDAY NIGHT INTO TUESDAY, BRINGING
ANOTHER REINFORCING SHOT OF COOL AIR. AS A RESULT, HIGH
TEMPERATURES ON TUESDAY WILL RUN AROUND 15 DEGREES BELOW NORMAL
FOR LATE AUGUST, WITH HIGHS IN THE MID TO UPPER 70S IN MOST
LOCATIONS!
LONG TERM
(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 941 PM CDT SAT AUG 23 2025
HIGH PRESSURE WILL CONTINUE TO BUILD IN FROM THE NORTH AND WEST
MID TO LATE WEEK, REINFORCING THE MOSTLY SUNNY AND DRY CONDITIONS
AND SUBSEQUENTLY THIS UNSEASONABLY COOL/DRY AIR MASS. THE COOLEST
TEMPERATURES SINCE EARLY/MID MAY WILL BE EXPERIENCED TUESDAY NIGHT
UNDER A CLEAR SKY AS TEMPERATURES FALL INTO THE MID TO UPPER 50S.
BEAUTIFUL WEATHER WILL CONTINUE WITH LOWER RH VALUES AND AMPLE
SUNSHINE EACH DAY THROUGH THE REMAINDER OF THE WORK WEEK AND INTO
LABOR DAY WEEKEND. HIGH TEMPERATURES EACH AFTERNOON SHOULD CLIMB
INTO THE LOWER 80S IN MOST LOCATIONS, WITH LOWS DROPPING INTO THE
UPPER 50S TO LOWER 60S EACH NIGHT.
