KEY MESSAGES
UPDATED AT 1134 PM CDT SUN OCT 25 2026
- AFTERNOON RH VALUES WILL DROP INTO THE 25-35% RANGE EACH OF THE
NEXT SEVERAL AFTERNOONS (MAINLY IN SOUTHERN MIDDLE TENNESSEE
AND NW ALABAMA), CREATING THE NEED FOR EXTRA CAUTION REGARDING
OUTDOOR BURNING THROUGH MIDWEEK.

FORECAST LATE SATURDAY NIGHT INTO SUNDAY.
NEAR TERM
(TODAY)
ISSUED AT 305 AM CDT MON OCT 26 2026
ANOTHER DAY THAT FEELS LIKE A RINSE AND REPEAT IN THIS PATTERN.
GRAB THAT JACKET BEFORE HEADING OUT THE DOOR TO YOUR MORNING
COMMUTE OR THE BUS STOP AS TEMPS WILL START OFF THE DAY IN THE
40S. STILL UNDER SFC HIGH PRESSURE THAT IS SPREAD ACROSS THE
SOUTHEAST AND THE MID ATLANTIC, CONDITIONS WILL REMAIN DRY ACROSS
THE TN VALLEY TODAY. THE LOW OVER IN THE PLAINS WILL STREAM IN
SOME MID TO HIGH CLOUD COVER, BUT TEMPS WILL STILL QUICKLY WARM
UP INTO THE LOWER 70S BY THIS AFTERNOON. WILL NOTE THAT WE'LL KEEP
AN EYE ON FIRE WEATHER AGAIN TODAY AS MIN RHS WILL ONLY BE UP TO
40% TODAY, AND THANKFULLY WIND VALUES WILL REMAIN LIGHT. PLEASE
USE EXTRA CAUTION REGARDING OUTDOOR BURNING TODAY.
SHORT TERM
(MONDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 858 PM CDT SUN OCT 25 2026
HIGH PRESSURE WILL REMAIN THE DOMINANT INFLUENCE DURING THE EARLY
TO MID WEEK, BUT THE CENTER OF IT WILL FLATTEN AND SHIFT EAST
INTO GA/SC BY LATE TUESDAY INTO WEDNESDAY. THIS WILL ALLOW A
COUPLE OF WEAK SHORTWAVES TO MOVE NORTH AND EAST FROM THE MID
SOUTH INTO THE OHIO VALLEY, CLIPPING OUR AREA. WITH THE AIR MASS
COMPLETELY DEVOID OF APPRECIABLE MOISTURE, THE IMPACT WILL MEAN
NOTHING BUT SOME CLOUD COVER WHICH WILL CREATE PERIODS OF PARTLY
TO MOSTLY CLOUDY CONDITIONS. DESPITE THIS, SUFFICIENT BREAKS IN
THE CLOUDS AND LIGHT SOUTHERLY WINDS WILL STILL ALLOW TEMPERATURES
TO REACH THE MID TO PERHAPS UPPER 70S EACH AFTERNOON.
LONG TERM
(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 858 PM CDT SUN OCT 25 2026
ANOTHER RIDGE WILL ATTEMPT TO BUILD BACK INTO THE TENNESSEE VALLEY
LATE THIS WEEK, RESULTING IN SUNNY/DRY WEATHER THURSDAY AND FRIDAY
AND HIGHS CLIMBING TO AROUND 80 DEGREES EACH DAY. THE RIDGE WILL
BEGIN TO SHIFT EAST ON SATURDAY, WITH AN AREA OF LOW PRESSURE
DEVELOPING OVER TEXAS AND THE LOWER MISSISSIPPI VALLEY SATURDAY
NIGHT INTO SUNDAY. AS IT STANDS RIGHT NOW, SATURDAY (HALLOWEEN)
LOOKS TO BE A WARM/DRY DAY WITH INCREASING CLOUD COVER -- WITH
POTENTIALLY SOME LOW RAIN CHANCES RETURNING TO THE FORECAST
SATURDAY EVENING. MEDIUM CHANCES OF SHOWERS WILL RETURN TO THE
FORECAST LATE SATURDAY NIGHT INTO SUNDAY AS THE LOW QUICKLY SHIFTS
EASTWARD ACROSS THE DEEP SOUTH. THIS WILL GIVE THE TENNESSEE
VALLEY, IT'S BEST SHOT AT APPRECIABLE RAINFALL IN A COUPLE WEEKS.
WE WILL NEED TO RESOLVE THE TIMING OF THE SYSTEM BETTER, BUT OUR
GREATEST CONFIDENCE APPEARS TO BE ON SUNDAY FOR NOW.
