NEAR TERM
(REST OF TONIGHT AND SUNDAY)
ISSUED AT 1056 PM CDT SAT OCT 17 2026
THE TENNESSEE VALLEY CONTINUES TO SIT COMFORTABLY UNDER THE
INFLUENCE OF HIGH PRESSURE. TEMPERATURES WILL REMAIN BELOW NORMAL
FALLING TO THE LOWER 40S TO EVEN UPPER 30S IN AREAS OF HIGHER
TERRAIN. BECAUSE OF THIS AND WEAKENING GRADIENT WINDS, PATCHY
FROST MAY FORM DURING THE EARLY MORNING HOURS IN HIGHER
ELEVATIONS. BE SURE TO GRAB A JACKET IF HEADED OUTDOORS TONIGHT OR
TOMORROW MORNING!
TOMORROW WILL BE ESPECIALLY NICE GIVEN THE CALMER NORTHERLY WINDS
AND ABUNDANT SUNSHINE. AFTER A CHILLY START TO THE MORNING,
AFTERNOON TEMPERATURES WILL RISE TO NEAR 70 DEGREES. DUE TO RECENT
TRENDS AND OBSERVATIONS, WE HAVE LOWERED DEWPOINTS DUE TO RECENT
UNDER REPRESENTATION OF THE DRY AIR AS HIGH PRESSURE KEEPS A MORE
CONTINENTAL ADVECTION REGIME IN PLACE. OVERALL, IT'LL FEEL VERY
COMFORTABLE AND FALL-LIKE OUTSIDE TODAY. ENJOY!
SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1056 PM CDT SAT OCT 17 2026
WHILE THE UPPER AIR PATTERN WON'T CHANGE SIGNIFICANTLY DURING THE
SHORT TERM PERIOD, UPPER RIDGING WILL CENTER MORE OVER THE EASTERN
CONUS AND WILL BRING WARMING TEMPERATURES TO THE TENNESSEE VALLEY.
THE GOOD NEWS IS THAT WITHOUT THE MOISTURE ADVECTION FROM THE
GULF, THE HEAT WILL FEEL A LOT LESS OPPRESSIVE WITHOUT THE
HUMIDITY WE HAVE SEEN IN RECENT WEEKS. AFTERNOON HIGHS WILL RISE
INTO THE LOW/MID 70S MONDAY AND THEN INTO THE MID/UPPER 70S ON
TUESDAY. CLEAR SKIES AND LIGHT WINDS WILL ALLOW FOR GOOD
RADIATIONAL COOLING, ALLOWING FOR OVERNIGHT LOWS IN THE UPPER 30S
TO MID 40S.
LONG TERM
(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 1056 PM CDT SAT OCT 17 2026
UPPER LEVEL RIDGING WILL PERSIST OVER THE SOUTHEAST TO BEGIN THE
LONG TERM PERIOD; HOWEVER, SYNOPTIC GUIDANCE SUGGESTS THAT THE UPPER
TROUGH OVER THE EASTERN SEABOARD WILL AMPLIFY BY LATE WEEK AND
ATTEMPT TO PUSH WESTWARD INTO THE SOUTH. ALTHOUGH, UNCERTAINTY
REMAINS IF THIS FEATURE WILL PUSH FAR ENOUGH WEST TO HAVE MUCH OF AN
EFFECT ON THE LOCAL AREA. THIS IS DUE TO THE STOUT RIDGE OVER THE
CENTRAL CONUS THAT LOOKS TO BE PUSHED EASTWARD OVER OUR REGION FRIDAY
INTO SATURDAY BY A PROGRESSIVE TROUGH OVER THE WESTERN CONUS.
MEANWHILE, SURFACE HIGH PRESSURE LOOKS TO LARGELY MAINTAIN ITS HOLD
OVER MUCH OF THE EASTERN CONUS THROUGH THE FIRST PART OF NEXT
WEEKEND. OVERALL, WITH CONTINUED SUBSIDENCE FROM SURFACE HIGH
PRESSURE AND PROXIMITY OF UPPER RIDGING, THE CURRENT FORECAST REMAINS
DEVOID OF RAIN CHANCES THROUGH AT LEAST EARLY NEXT WEEKEND. IN
ADDITION, THE FALL-LIKE WEATHER CONTINUES WITH FORECAST HIGHS IN THE
MID TO UPPER 70S AND LOWS MAINLY IN THE MID TO UPPER 40S.
