NEAR TERM
(TONIGHT)
ISSUED AT 206 PM CDT FRI SEP 12 2025
AFTERNOON TEMPS HAVE REACHED THE MID TO UPPER 80S AT THIS HOUR
WITH DAYTIME CU ACROSS THE TN VALLEY. HIGH PRESSURE IN PLACE WILL
KEEP CONDITIONS DRY AND ONCE THE DAYTIME CU FADES WITH SUNSET,
SKIES WILL BE MOSTLY CLEAR OVERNIGHT. WITH THE LACK OF CLOUD COVER
AND LIGHT/VARIABLE WINDS OVERNIGHT, COULD SEE ANOTHER ROUND OF
PATCHY FOG LATE TONIGHT INTO EARLY MORNING HOURS TOMORROW.
OTHERWISE, LOWS WILL BE NEAR NORMAL IN THE UPPER 50S TO LOWER 60S.
SHORT TERM
(SATURDAY THROUGH MONDAY)
ISSUED AT 1010 AM CDT FRI SEP 12 2025
BY SATURDAY HIGH PRESSURE AT THE SURFACE AND ALOFT WILL BEGIN TO
NUDGE INTO THE TN VALLEY. THIS WILL JUMP START OUR LONG STRETCH OF
HOT AND DRY WEATHER EXTENDING FROM THE SHORT TERM FORECAST THROUGH
THE LONG TERM. UNDER HIGH PRESSURE, SUBSIDENCE WILL PROMOTE MOSTLY
CLEAR SKIES AND LOW RAIN CHANCES. TEMPS WILL SUBSEQUENTLY ENTER A
WARMING TREND THROUGH THE WEEKEND WARMING FROM THE HIGH 80/ LOW
90S ON SATURDAY TO LOW TO MID 90S BY MONDAY. THESE TEMPS ARE ABOUT
5-7 DEGREES ABOVE NORMAL FOR MID SEPTEMBER IN THE TN VALLEY.
THUS, DESPITE BEING WELL VERSED IN HEAT, NEXT WEEK WILL REQUIRE
SOME SLIGHT ADJUSTMENTS BACK TO SUMMER HEAT SAFETY FOR THOSE
PARTICIPATING IN OUTDOOR ACTIVITIES.
THE SILVER LINING OF THE FORECAST IS THAT WE WILL REMAIN IN
NORTHERLY FLOW THROUGH THIS PERIOD ON THE EASTERN EDGE OF HIGH
PRESSURE. THIS WILL WORK TO KEEP HIGHER DEW POINTS CONFINED TO
THE GULF COAST LEAVING US WITH MUCH LOWER AFTERNOON HUMIDITY AND
NEGATING ANY HEAT ADVISORY CONCERNS AS HEAT INDICES WILL MIRROR
THE ACTUAL TEMPERATURES. SO WHILE ABNORMALLY HOT FOR MID
SEPTEMBER, WILL RETAIN SOME SEMBLANCE OF FALL WITH RH VALUES IN
THE 30-50% RANGE EACH AFTERNOON.
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 946 PM CDT THU SEP 11 2025
A MEAN TROUGHING PATTERN ALONG THE EASTERN SEABOARD SHOULD
CONTINUE WAS WE GO INTO THE NEW WEEK. OUR LOCATION WELL TO THE
SE OF A FRONTAL BOUNDARY OVER THE GREAT PLAINS WILL HELP KEEP A
DRY AND WARM TREND GOING THROUGH THE MIDDLE OF NEXT WEEK. UPPER
RIDGING POSITIONED JUST WEST OF THE COASTAL TROUGH SHOULD ALSO
MAINTAIN ITS LOCATION. THUS DAILY HIGHS FOR THE MON-THU TIME
FRAME SHOULD RANGE FROM THE MID/UPPER 80S IN THE HIGHER ELEVATIONS
AND MORE EASTERN LOCATIONS, WITH LOW/MID 90S EXPECTED FOR THE
LOWER ELEVATIONS, ESPECIALLY WEST OF I-65. LOW TEMPERATURES EACH
NIGHT SHOULD AVERAGE IN THE LOW/MID 60S.
