NEAR TERM
(REST OF TONIGHT AND TUESDAY)
ISSUED AT 940 PM CDT MON OCT 12 2026
TRANQUIL WEATHER ACROSS THE TENNESSEE VALLEY THIS EVENING WITH
HIGH PRESSURE REMAINING THE DOMINANT WEATHER FEATURE OVER THE
AREA. THE COMBINATION OF A CLEAR SKY AND CALM WINDS WILL CREATE A
GOOD SETUP UP FOR RADIATIONAL COOLING AS TEMPERATURES DROP INTO
THE MID/UPPER 50S TO LOWER 60S. THIS WILL ALSO BE A GOOD SETUP FOR
PATCHY FOG DEVELOPMENT IN THE MOIST BOUNDARY LAYER IN SHELTERED
VALLEYS. ANY FOG THAT DOES DEVELOP WILL DISSIPATE BY MID-MORNING
ON TUESDAY. THE END RESULT WILL BE A CLEAR/SUNNY AND DRY DAY WITH
HIGH PRESSURE IN CONTROL OF OUR SENSIBLE WEATHER. WITH AMPLE
SUNSHINE AND LIGHT SOUTHERLY WINDS, HIGHS WILL AGAIN REACH THE
UPPER 80S TO LOWER 90S.
SHORT TERM
(TUESDAY NIGHT THROUGH THURSDAY)
ISSUED AT 940 PM CDT MON OCT 12 2026
A LARGE AREA OF HIGH PRESSURE WILL ROTATE OVER THE DEEP SOUTH
WEDNESDAY AND THURSDAY, CONTINUED WARM/SUNNY CONDITIONS WILL
PERSIST THROUGH MUCH OF THE WORK WEEK. AMPLE SUNSHINE AND LIGHT
SOUTHERLY WINDS WILL AGAIN HELP PUSH HIGH TEMPERATURES INTO THE
UPPER 80S TO LOWER 90S IN MOST LOCATIONS BOTH DAYS, WITH LOWS
REMAINING IN THE LOW TO MID 60S. THE SOUTHERLY WINDS WILL ALSO
HELP ADVECT MOISTURE INTO THE AREA, AS EVIDENCED BY DEWPOINTS
CLIMBING INTO THE MID TO UPPER 60S. COMBINED WITH TEMPERATURES IN
THE LOWER 90S, THIS WILL PUSH HEAT INDEX VALUES IN THE LOW TO MID
90S AND POTENTIALLY CREATE SOME MODERATE (LEVEL 2/4) HEAT IMPACTS
BOTH DAYS. THESE HIGH TEMPERATURES ARE WELL ABOVE THE SEASONAL
NORM, SO CONTINUE PRACTICING HEAT SAFETY IF YOU HAVE OUTDOOR
PLANS!
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 940 PM CDT MON OCT 12 2026
A STRONG UPPER TROUGH OVER THE GREAT LAKES WILL PUSH A STRONG COLD
FRONT INTO THE OHIO AND TENNESSEE VALLEYS THURSDAY NIGHT INTO
FRIDAY. NOT ANTICIPATING MUCH IN THE WAY OF RAIN CHANCES WITH
THIS FEATURE, BUT SOME ADDED CLOUD COVER MAY ACCOMPANY IT AS IT
PASSES THROUGH THE AREA. THE MAIN IMPACT WILL BE THE BREEZY
CONDITIONS THAT WILL BE OBSERVED ON FRIDAY WITH THE PASSAGE OF THE
FRONT AND MUCH COOLER AND DRIER AIR MASS THAT WILL ADVECT INTO
THE AREA IN ITS WAKE. HIGHS ON FRIDAY (THE TRANSITION DAY) WILL
RUN ABOUT 10 DEGREES LOWER THAN WEDNESDAY/THURSDAY (HIGHS IN THE
LOWER 80S), BUT A STRONG PUSH OF COOLER AIR WILL OCCUR OVERNIGHT
AS LOWS WILL DROP LIKE A ROCK INTO THE MID TO UPPER 40S BY EARLY
SATURDAY MORNING. THIS AUTUMN-LIKE AIR MASS WILL TAKE HOLD ON
SATURDAY AS HIGHS IN THE UPPER 60S WILL BE COMMON ON SATURDAY AND
THE UPPER 60S TO LOWER 70S ON SUNDAY (WITH LOWS IN THE 40S). AS
RIDGING BUILDS IN, A GRADUAL WARMING TREND WILL TAKE PLACE AS
HIGHS RETURN TO THE MID TO UPPER 70S BY MONDAY.
