..NEW NEAR TERM
KEY MESSAGES
UPDATED AT 103 PM CDT TUE OCT 27 2026
- MEDIUM CHANCES OF SHOWERS AND A FEW STORMS WILL RETURN TO THE
FORECAST SATURDAY INTO SUNDAY.
NEAR TERM
(TONIGHT)
ISSUED AT 103 PM CDT TUE OCT 27 2026
TRANQUIL CONDITIONS ACROSS THE REGION AGAIN THIS AFTERNOON, BUT
CLOUDS WILL BE ON THE INCREASE LATER THIS EVENING AND OVERNIGHT AS
A SHORTWAVE TROUGH RIPPLES ACROSS THE MID SOUTH AND LOWER OHIO
VALLEY. THOUGH THE AREA IS DEVOID OF MOISTURE AT THE LOWER-LEVELS,
THIS WILL STILL RESULT IN AN INCREASE OF MID/HIGH CLOUDS OVERNIGHT,
WHICH MAY HELP KEEP TEMPERATURES A FEW DEGREES HIGHER THAN LAST
NIGHT (LOWS IN THE UPPER 40S TO LOWER 50S). IF THERE ARE A FEW
BREAKS IN THE CLOUDS SOME VERY LOCALIZED PATCHY FOG COULD DEVELOP
IN SHELTERED VALLEYS, BUT GIVEN THE POTENTIAL FOR CLOUD COVER HAVE
KEPT A MENTION OF THIS OUT OF THE FORECAST FOR NOW.
SHORT TERM
(WEDNESDAY THROUGH THURSDAY)
ISSUED AT 828 AM CDT TUE OCT 27 2026
THE AFOREMENTIONED SHORTWAVE WILL QUICKLY PASS THROUGH THE REGION
ON WEDNESDAY, BUT OTHER THAN CLOUD COVER, NO IMPACTS ARE FORECAST.
AND, DESPITE THESE CLOUDS, HIGHS IN THE 70S WILL BE COMMON AGAIN.
AN AREA OF HIGH PRESSURE OVER THE NORTHERN GULF WILL AMPLIFY ON
THURSDAY IN WAKE OF THE EXITING SHORTWAVE. THIS WILL RESULT IN A
SUNNY/WARM DAY, WITH SOUTHERLY WINDS PUSHING HIGHS CLOSE TO THE 80
DEGREE MARK.
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 835 PM CDT MON OCT 26 2026
THE LONG TERM PERIOD WILL BEGIN WITH ZONAL FLOW ALOFT AS THE TN
VALLEY SITS BETWEEN LOW PRESSURE OFF THE WESTERN ATLANTIC AND AN
AMPLIFYING RIDGE OVER THE SOUTHERN PLAINS. THIS WILL ULTIMATELY
RESULT IN TROPICAL AIR ADVECTION AHEAD OF AN UPPER WAVE PROGGED TO
MOVE ACROSS THE CENTRAL PLAINS AND INTO THE UPPER MIDWEST OVER THE
WEEKEND, BRINGING INCREASED MOISTURE AND ABOVE NORMAL TEMPERATURES TO
THE AREA. THERE IS SOME INDICATION THAT A SECONDARY LOW MAY FORM
ACROSS THE OZARKS/MID MS RIVER VALLEY THAT WOULD ENHANCE SYNOPTIC
LIFT CLOSER TO HOME AND WOULD BRING INCREASING RAIN CHANCES ON
HALLOWEEN. FOR NOW WE WILL STICK WITH BLENDED GUIDANCE, BRINGING LOW
TO MEDIUM (30-50%) CHANCES FOR RAIN BEGINNING HALLOWEEN AFTERNOON AND
INCREASING OVERNIGHT, AND CONTINUING THROUGH SUNDAY. WHILE SEVERE
WEATHER DOES NOT LOOK TO BE A THREAT WITH THIS SYSTEM AT THIS TIME,
LOW CHANCES FOR THUNDERSTORMS WILL EXIST ON SUNDAY.
THIS SYSTEM WILL EXIT THE AREA LATE SUNDAY AND HIGH PRESSURE WILL
MOVE INTO THE AREA BY THE START OF THE NEXT WORK WEEK. THIS LOOKS TO
BE SHORT LIVED, AS ANOTHER AND POTENTIALLY MORE DYNAMIC SYSTEM SITS
JUST BEYOND THE DAY 7 PERIOD AND COULD BRING ADDITIONAL RAIN AND
THUNDERSTORMS TO THE AREA EARLY NEXT WEEK. SINCE THIS IS BEYOND THE
7 DAY FORECAST PERIOD AT THIS TIME, WE WILL HOLD ON FOR BETTER
FORECAST CONSISTENCY BUT FEEL IT WILL BEAR WATCHING AS IT MAY IMPACT
ELECTION DAY.
AVIATION
(18Z TAFS)
ISSUED AT 1134 AM CDT TUE OCT 27 2026
VFR CONDITIONS WILL BE THE PREDOMINANT FLIGHT CATEGORY AT EACH
TERMINAL THROUGH THE PERIOD WITH LIGHT WINDS. MID TO HIGH CLOUDS
WILL INCREASE OVERNIGHT AHEAD OF A WEAK FRONT THAT WILL MOVE
THROUGH THE REGION TONIGHT INTO WEDNESDAY. A LOW CHANCE OF PATCHY
FOG WILL EXIST, BUT CONFIDENCE IS TOO LOW ON ITS OCCURRENCE BASED
ON THE AFOREMENTIONED CLOUDS, SO WILL KEEP OUT OF THE FORECAST
FOR NOW.
