DISCUSSION
(THIS AFTERNOON THROUGH NEXT TUESDAY)
ISSUED AT 1118 AM CST WED NOV 19 2025
A STALLED SURFACE FRONT REMAINS CENTERED OVER THE TENNESSEE /
MISSISSIPPI BORDER THIS MORNING, KEEPING OVERCAST SKIES ACROSS
THE MAJORITY OF THE MID-SOUTH. TODAY'S AFTERNOON HIGHS WILL VARY
DEPENDING ON LOCATION DUE TO THE STALLED BOUNDARY. FOR AREAS
ALONG AND NORTH OF I-40, EXPECT HIGHS IN THE UPPER 60S TO LOW
70S. FURTHER SOUTH, HIGHS WILL RANGE FROM THE MID 70S TO LOW 80S.
ELSEWHERE IN CONUS TODAY, A LARGE UPPER LEVEL TROUGH CONTINUES TO
CHURN OVER THE DESERT SOUTHWEST. THIS FEATURE WILL EJECT EASTWARD
OVERNIGHT, PROVIDING ENOUGH MOMENTUM TO SEND THE AFOREMENTIONED
STALLED BOUNDARY NORTH AS A WARM FRONT. SIGNIFICANT MOISTURE
RETURN WILL OCCUR OVERNIGHT INTO THURSDAY WITH PRECIPITABLE WATER
VALUES REACHING THE 99TH PERCENTILE BY MIDDAY. SHOWERS AND
THUNDERSTORMS ARE ANTICIPATED THURSDAY AND FRIDAY, WITH
1.5 INCHES OF RAIN FALLING NORTH OF I-40. SEVERE STORM CHANCES ON
FRIDAY WILL BE HAMPERED BY POOR LAPSE RATES AND PERSISTENT CLOUD
COVER, LIMITING DESTABILIZATION. RAIN CHANCES FINALLY TAPER OFF
ON SATURDAY AS A WEAK COLD FRONT SWINGS THROUGH THE REGION. A FEW
STRAY SHOWERS CANNOT BE RULED OUT THROUGH SUNDAY, BUT EXPECT THE
MAJORITY OF THE WEEKEND TO BE DRY WITH HIGHS IN THE 60S AND 70S.
NEXT WEEK, A RATHER PROGRESSIVE SYNOPTIC PATTERN EMERGES AS YET
ANOTHER UPPER LEVEL TROUGH EMERGES FROM THE DESERT SOUTHWEST.
BOTH THE GFS AND ECMWF DEPICT A LEADING SHORTWAVE EJECTING
EASTWARD TOWARDS THE MID-SOUTH EARLY MONDAY. THIS DISTURBANCE
WILL ALLOW ELEVATED DEWPOINTS TO FILTER INTO THE REGION, INCREASING
RAIN CHANCES ONCE AGAIN. GREATER PRECIPITATION CHANCES MANIFEST
ON TUESDAY AS THE AFOREMENTIONED TROUGH FINALLY REACHES THE MID-
SOUTH. AN ASSOCIATED SURFACE LOW IS FORECAST TO DEVELOP IN THE
OK/TX VICINITY EARLY TUESDAY AND TREK EAST. HOWEVER, LARGE SPREAD
IN THE PRECISE LOCATION OF THIS LOW PRESSURE MAKES IT HARD TO
PINPOINT WHERE AN ASSOCIATED WARM-SECTOR WILL EMERGE. THIS,
COMBINED WITH THE POTENTIAL FOR ONGOING MORNING CONVECTION AND
INCREASED CLOUD COVER, KEEP SEVERE STORM CHANCES LOW (<10%) FOR
TUESDAY. DEPENDING ON HOW GUIDANCE SHAKES OUT OVER THE COMING
DAYS, SEVERE STORM PROBABILITIES MAY INCREASE. THE GOOD NEWS: A
STRONG COLD FRONT WILL SWING THROUGH THE REGION AFTER TUESDAY'S
SYSTEM, RETURNING OUR TEMPERATURES TO NEAR-NORMAL.

AVIATION
(12Z TAFS)
ISSUED AT 547 AM CST WED NOV 19 2025
MULTIPLE AREAS OF MVFR CIGS ARE CURRENTLY DRAPED ACROSS THE MID-
SOUTH THIS MORNING AND WILL BE THE PRIMARY IMPACT TO AVIATION
WITH
THIS TAF ISSUANCE. CURRENT EXPECTATIONS ARE FOR THESE CLOUDS TO
PERSIST THIS MORNING ALONGSIDE THE ARRIVAL OF AN ADDITIONAL AREA
OF MVFR/IFR CIGS FROM THE NORTH. SOME DIURNAL LIFTING AND/OR
EROSION IS POSSIBLE BY EARLY AFTERNOON, WHICH COULD BRING VFR
CONDITIONS BACK TO THE REGION. HOWEVER, THIS ASPECT OF THE
FORECAST IS STILL QUITE UNCERTAIN AND WILL DEPEND ON OBSERVATIONS
LATER THIS MORNING TO SORT OUT. THEREFORE, HAVE ALLOWED FOR
MVFR AT MEM/JBR/MKL THIS MORNING WITH A GRADUAL RISE INTO VFR BY
MID AFTERNOON.
REGARDLESS OF HOW THE FORECAST EVOLVES THIS AFTERNOON, GUIDANCE
BRINGS CIGS BACK OVER THE REGION TONIGHT. CIGS ARE EXPECTED TO
EVENTUALLY DROP INTO MVFR AT MEM/JBR/MKL AND REMAIN THAT WAY
UNTIL TOMORROW MORNING.
FIRE WEATHER
ISSUED AT 1118 AM CST WED NOV 19 2025
WETTING RAIN CHANCES RETURN ON THURSDAY AND WILL PERSIST THROUGH
THE END OF THE WEEK. MINRH VALUES WILL REMAIN ABOVE 50% FOR THE
FORESEEABLE FUTURE WITH ADDITIONAL RAIN CHANCES RETURNING NEXT
WEEK. FIRE WEATHER CONCERNS REMAIN LOW.
