KEY MESSAGES
UPDATED AT 1123 PM CDT SAT SEP 13 2025
- ISOLATED SHOWERS AND THUNDERSTORMS WILL PROVIDE LIMITED RELIEF
FROM THE DROUGHT CONDITIONS LATE SUNDAY AFTERNOON INTO SUNDAY
NIGHT ACROSS AREAS MAINLY NORTH OF I-40. OTHERWISE, HOT AND DRY
CONDITIONS WILL PERSIST ACROSS THE MID-SOUTH THROUGH MID-WEEK
WITH HIGHS IN THE 90S.
- DROUGHT CONDITIONS ARE EXPECTED TO PERSIST OR WORSEN DUE TO LACK
OF PRECIPITATION AND PROLONGED HEAT. THIS ALSO RAISES WILDLAND
FIRE CONCERNS THROUGH MID-WEEK.

00Z UPPER AIR ANALYSIS FEATURES AN OMEGA BLOCK CENTERED OVER THE
MISSISSIPPI VALLEY, WITH UPPER-LEVEL TROUGHS ALONG BOTH THE EAST
AND WEST COAST OF THE UNITED STATES. A FEW HIGH CLOUDS ARE
PRODUCING MOSTLY CLEAR SKIES ACROSS THE MID-SOUTH LATE THIS
EVENING WITH TEMPERATURES MOSTLY IN THE LOWER TO MIDDLE 70S.
LATEST SHORT-TERM MODEL TRENDS SUFFICIENT SHEAR AND INSTABILITY
WILL BE PRESENT FOR THE DEVELOPMENT OF ISOLATED SHOWERS AND
THUNDERSTORMS ACROSS PORTIONS OF THE MID-SOUTH MAINLY SUNDAY
EVENING, ESPECIALLY NORTH OF I-40. THE MAIN THREAT WILL BE
LOCALIZED HEAVY RAINFALL FOR AREAS THAT ARE FORTUNATE TO RECEIVE
ANY RAIN AS PRECIPITABLE WATER VALUES WILL BE AROUND 1.7 INCHES.
OTHERWISE, RAIN CHANCES WILL REMAIN HARD TO COME BY ACROSS THE
AREA UNTIL THE BLOCKING PATTERN BREAKS DOWN.
LONG-RANGE ENSEMBLES INDICATE THE OMEGA BLOCK WILL BREAK DOWN BY
LATE WEEK, WITH A MODEST INCREASE IN SHOWER AND THUNDERSTORM
CHANCES RETURNING FOR THURSDAY AND FRIDAY. HOWEVER, ANY
APPRECIABLE RAIN TO ALLEVIATE THE MODERATE TO SEVERE DROUGHT
CONDITIONS ACROSS THE MID-SOUTH IS NOT EXPECTED.
