NEAR TERM
(TONIGHT)
ISSUED AT 130 PM CDT FRI OCT 31 2025
DRY AND COOLER WEATHER IS FORECAST TONIGHT AS SFC HIGH PRESSURE
CONTINUES TO INFLUENCE THE AREA. HOWEVER, CLOUD COVER IS FORECAST
TO BEGIN PUSHING IN AROUND MIDNIGHT FROM THE NW. THIS SHOULD
MITIGATE DENSE, WIDESPREAD FOG. HOWEVER, PATCHY FOG IS FORECAST
(ESPECIALLY ALONG AND EAST OF I-65) THROUGH THE EARLY MORNING
HOURS AS CLEAR SKIES LINGER. WITH THE AFTERNOON UPDATE, HAVE
CONTINUED TO HOLD OFF FROM ISSUING A FROST ADVISORY AS CLOUD COVER
AND TEMPERATURES WILL NOT SUPPORT ONE AT THIS TIME.
PREVIOUS DISCUSSION:
CHILLY START TO THE MORNING WITH A LITTLE BIT OF GROUND FOG IN THE
VALLEYS AND NEAR WATER WITH TEMPS IN THE MID 30S TO LOWER 40S.
CURRENTLY WE ARE RUNNING ABOUT 10 DEGREES COOLER THAN WE WERE THIS
TIME YESTERDAY WITH TEMPS IN THE LOWER 50S. HIGH PRESSURE IN PLACE
WILL KEEP THIS HALLOWEEN DRY (UNLIKE LAST YEAR) BUT ALSO COOLER
WITH HIGHS THIS AFTERNOON ONLY IN THE LOWER 60S. DURING THE PEAK
TIMEFRAME FOR OUTDOOR ACTIVITIES (5-9PM), TEMPS WILL START OFF IN
THE UPPER 50S, BUT AFTER THE SUN SETS, REACH THE LOWER 50S AND
THEN DOWN IN TO THE UPPER 40S BY THE TIME THINGS ARE WRAPPING UP
FOR THE NIGHT. HOW QUICKLY CLOUD COVER MAKES ITS WAY IN WILL
DEPEND ON JUST HOW LOW THE OVERNIGHT LOWS REACH, HOWEVER THE
COOLER SPOTS AND THE VALLEYS SHOULD SEE THE LOWER 30S WITH MID TO
UPPER 30S ELSEWHERE. AT THIS TIME WITHHOLDING FROM ISSUING A FROST
ADVISORY FOR TONIGHT, HOWEVER WILL MONITOR TRENDS AND ENCOURAGE
EVERYONE TO PROTECT SENSITIVE PLANTS AND OUTDOOR PETS FROM THE
COLD.
SHORT TERM
(SATURDAY THROUGH MONDAY)
ISSUED AT 1029 AM CDT FRI OCT 31 2025
COLD START TO THE MORNING ON SATURDAY WITH TEMPS EXPECTED TO BE
IN THE 30S BUT WILL WARM UP INTO THE LOWER 60S BY THE AFTERNOON.
WILL SEE AN INCREASE IN CLOUDS AS AN UPPER LEVEL LOW DIVES THROUGH
THE MIDWEST, PUSHING OUT THE HIGH PRESSURE IN PLACE. THIS WILL
BRING AN ASSOCIATED COLD FRONT THROUGH SATURDAY NIGHT INTO SUNDAY,
SPREADING LOW TO MEDIUM CHANCES (20-60%) OF SHOWERS TO THE TN
VALLEY. ANOTHER SHOT OF COLD AIR WILL BE FELT BEHIND THE COLD
FRONT AS HIGHS WILL ONLY REACH THE UPPER 50S ON SUNDAY AND LOWS IN
THE LOW TO MID 30S. TRENDS WILL BE MONITORED ON IF A FROST
ADVISORY WILL BE NEEDED FOR SUNDAY NIGHT. REGARDLESS, PROTECT
OUTDOOR PLANTS AND PETS, AND BUNDLE UP. A SLIGHT REBOUND WILL BE
FELT ON MONDAY WITH HIGHS IN THE LOWER 60S AS HIGH PRESSURE IN THE
SOUTHERN PLAINS STARTS TO BUILD EASTWARD AND SKIES WORK ON
BECOMING MOSTLY SUNNY.
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 958 PM CDT THU OCT 30 2025
ANOTHER CLEAR/CALM/COOL NIGHT ON SUNDAY NIGHT COULD AGAIN RESULT
IN THE FORMATION OF FROST BY EARLY MONDAY MORNING ACROSS THE
REGION. THE WEATHER STORY FOR NEXT WEEK, HOWEVER, WILL BE
REBOUNDING TEMPERATURES AND A WARMING TREND AS A BROAD AREA OF
HIGH PRESSURE BUILDS EAST INTO THE DEEP SOUTH FROM THE SOUTHERN
PLAINS. THE END RESULT WILL BE MOSTLY SUNNY AND DRY CONDITIONS
EACH DAY AND A GRADUAL WARMING TREND AS HIGHS RETURN TO THE MID TO
UPPER 60S ON MONDAY AND TUESDAY AND THE UPPER 60S TO LOWER 70S
WEDNESDAY AND THURSDAY. LOWS WILL REMAIN IN THE 40S EACH NIGHT
WITH NO THREAT OF FROST/FREEZE CONDITIONS.
AVIATION
(00Z TAFS)
ISSUED AT 705 PM CDT FRI OCT 31 2025
VFR/SKC CONDITIONS ARE CURRENTLY OBSERVED AT THE HSV/MSL
TERMINALS, WITH A LGT WEST WIND. OVER THE COURSE OF THE EVENING,
AN OVERCAST LAYER OF CS WILL QUICKLY OVERSPREAD THE REGION,
PERHAPS HAVING AN IMPACT ON BOTH THE COVERAGE AND DENSITY OF BR/FG
WITHIN AN OTHERWISE FAVORABLE ENVIRONMENT PROVIDED BY A RIDGE OF
HIGH PRESSURE BUILDING NORTHEASTWARD INTO THE SOUTHERN
APPALACHIANS. NEVERTHELESS, LIMITED VSBY REDUCTIONS WILL BE
POSSIBLE BTWN 8-13Z (MAINLY IN VALLEYS AND NEAR LARGE BODIES OF
WATER). LIGHT SSW FLOW WILL RETURN AFTER SUNRISE, AS HIGH PRESSURE
SHIFTS EASTWARD ACROSS THE CAROLINAS AND A COLD FRONT DRIFTS VERY
SLOWLY SOUTHEASTWARD ACROSS THE MID-MS VALLEY. STRENGTHENING LIFT
AHEAD OF AN UPPER-LVL TROUGH (TO OUR NORTHWEST) WILL RESULT IN
GRADUAL SATURATION ALOFT OVER THE COURSE OF THE DAY, WITH THE BASE
OF THE OVERCAST CLOUD LAYER FALLING TO ARND 10 KFT BY THE END OF
THE TAF PERIOD.
