NEAR TERM
(REST OF TONIGHT AND MONDAY)
ISSUED AT 858 PM CDT SUN OCT 25 2026
TRANQUIL CONDITIONS AGAIN TONIGHT, WITH A CLEAR SKY AND CALM
WINDS ALLOWING FOR GOOD RADIATIONAL COOLING AS TEMPERATURES HAVE
DROPPED OFF QUICKLY AFTER SUNSET. EXPECT THEM TO EVENTUALLY BOTTOM
OUT IN THE MID TO UPPER 40S IN MOST LOCATIONS BY EARLY MONDAY
MORNING. HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE
ACROSS THE REGION ON MONDAY, BUT MID/HIGH CLOUDS FROM AN AREA OF
LOW PRESSURE OVER THE PLAINS WILL FILTER THROUGH THE REGION DURING
THE DAY. THERE SHOULD BE ENOUGH BREAKS IN THE CLOUDS TO STILL
WARM INTO THE LOW TO MID 70S IN MOST LOCATIONS BY THE AFTERNOON.
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.
