KEY MESSAGES
UPDATED AT 828 AM CDT TUE OCT 27 2026
- MEDIUM CHANCES OF SHOWERS AND A FEW STORMS WILL RETURN TO THE
FORECAST SATURDAY INTO SUNDAY.
NEAR TERM
(REST OF TODAY AND TONIGHT)
ISSUED AT 828 AM CDT TUE OCT 27 2026
SOME LOCALIZED, PATCHY DENSE FOG DEVELOPED ALONG THE SHELTERED
RIVER VALLEYS EARLY THIS MORNING, BUT THIS FOG WILL QUICKLY
DISSIPATE OVER THE NEXT HOUR OR SO. THE END RESULT WILL BE A
MOSTLY SUNNY DAY WITH HIGH PRESSURE IN CONTROL OF OUR SENSIBLE
WEATHER. THIS WILL ALLOW TEMPERATURES TO CLIMB INTO THE MID TO
UPPER 70S IN MOST LOCATIONS BY THIS AFTERNOON. WE WILL LIKELY
AGAIN MIX OUT IN THE AFTERNOON, WITH DEWPOINTS DROPPING INTO THE
MID TO UPPER 40S -- WITH MIN RH VALUES AROUND 30-35 PERCENT IN THE
AFTERNOON. DESPITE THE WEAK WINDS, CAUTION IS URGED WITH ANY POTENTIAL
OUTDOOR BURNING DUE TO THE DRY FUELS AND LOWER RH VALUES. CLOUDS
WILL INCREASE OVERNIGHT AS A WEAK SHORTWAVE APPROACHES THE REGION.
A DRY AIR MASS WILL PREVENT ANY PRECIPITATION FROM OCCURRING, BUT
MOSTLY CLOUDY CONDITIONS WILL KEEP LOWS A FEW DEGREES HIGHER IN
THE UPPER 40S TO LOWER 50S.
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.

PERSIST THROUGH THE REMAINDER OF THE PERIOD.
