DISCUSSION
(THIS AFTERNOON THROUGH NEXT WEDNESDAY)
ISSUED AT 1210 PM CST THU NOV 20 2025
SHOWERS AND THUNDERSTORMS CONTINUE TO FORM ALONG A RETREATING
WARM FRONT THIS MORNING, RESULTING IN A GLOOMY DAY FOR THE MID-
SOUTH. RAIN CHANCES WILL PERSIST THROUGH THE REMAINDER OF TODAY
WITH ABOUT AN INCH OF RAIN FALLING IN AREAS NORTH OF THE I-
40 CORRIDOR. PRECIPITATION WILL CONTINUE INTO FRIDAY AS A LARGE
UPPER LEVEL TROUGH EJECTS OUT OF THE DESERT SOUTHWEST. AN
ADDITIONAL HALF INCH OF RAIN IS FORECAST THROUGH TOMORROW
EVENING, BRINGING THE TWO DAY RAINFALL TOTAL TO AROUND 1.5 INCHES
FOR PORTIONS OF THE MID-SOUTH. FORTUNATELY, CONDITIONS WILL DRY
OUT ON SATURDAY AS A COLD FRONT SWINGS THROUGH THE REGION. THE
REMAINDER OF THE WEEKEND WILL BE MOSTLY DRY AND COOLER WITH HIGHS
IN THE 60S AND 70S THROUGH SUNDAY.
ELSEWHERE IN CONUS ON SATURDAY, ANOTHER LARGE UPPER LEVEL TROUGH
WILL DEVELOP OVER THE DESERT SOUTHWEST. A LEADING SHORTWAVE WILL
EJECT TOWARDS THE MID-SOUTH ON MONDAY, ALLOWING DEWPOINTS TO
CLIMB TO THE 50S AND 60S. SHOWERS AND THUNDERSTORMS WILL DEVELOP
BY MIDDAY, THOUGH CONTINUAL CLOUD COVER WILL LIMIT
DESTABILIZATION. THUNDERSTORMS WILL LINGER INTO TUESDAY MORNING,
BUT GIVEN THE WEAKENING TREND OF THE UPPER TROUGH AND ITS
NORTHERLY TRACK, SEVERE CHANCES WILL BE MINIMAL (<10%). DEPENDING
ON HOW MODELS RESOLVE THIS SYSTEM AS WE MOVE CLOSER TO THE EVENT,
SEVERE STORMS CHANCES MAY CHANGE.
THANKSGIVING TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL AS AN
UPPER LEVEL LOW OVER THE NORTHERN UNITED STATES / CANADA BORDER
EJECTS A STRONG COLD FRONT TO THE MID-SOUTH ON TUESDAY. EVENTUAL
FROPA IS ANTICIPATED EARLY WEDNESDAY WITH MUCH COOLER AND DRIER
AIR FILTERING INTO THE REGION. DEWPOINTS WILL DROP TO THE 30S
AREAWIDE BY THE EVENING HOURS, SETTING THE STAGE FOR EFFICIENT
RADIATIONAL COOLING. FREEZING TEMPERATURES WILL START THE
THANKSGIVING HOLIDAY. CONTINUAL CAA WILL TEMPER HIGHS ON THURSDAY
WITH THE MAJORITY OF THE AREA REMAINING IN THE 50S.
