NEAR TERM
(THROUGH THURSDAY)
ISSUED AT 1258 AM CDT THU AUG 28 2025
ANOTHER WAVE OF PRECIPITATION/THUNDERSTORMS, WITH POTENTIAL FOR
SEVERE WEATHER AND LOCALIZED HEAVY RAINFALL, IS EXPECTED ACROSS
PORTIONS OF THE AREA TODAY.
REMNANT PRECIPITATION/THUNDER FROM A PREVIOUS INTENSE SUPERCELL
ACROSS THE OKLAHOMA PANHANDLE EARLIER CONTINUES TO ENTER PORTIONS
OF NORTHWESTERN OKLAHOMA JUST AFTER MIDNIGHT. ADDITIONAL THUNDERSTORM
COVERAGE, IN RESPONSE TO A NOTABLE LOW-LEVEL JET/WARM AIR
ADVECTION REGIME, IS EXPANDING ACROSS SOUTHERN AND CENTRAL
KANSAS. BOTH AREAS OF ACTIVITY MAY TEND TO SLOWLY DRIFT EAST-
SOUTHEASTWARD INTO/ACROSS PORTIONS OF NORTHERN OKLAHOMA THROUGH
DAYBREAK THIS MORNING. WHILE THE BOUNDARY LAYER CONTINUES TO
STABILIZE, ENOUGH ELEVATED INSTABILITY AND WIND SHEAR EXISTS FOR A
LOCALIZED STRONG WIND AND HAIL OCCURRENCE DURING THE PREDAWN
HOURS. A RISK FOR HEAVY RAINFALL ALSO EXISTS ACROSS PORTIONS OF FAR
NORTH-CENTRAL OKLAHOMA. A FLOOD WATCH HAS BEEN POSTED FOR KAY,
NOBLE AND PAYNE COUNTIES, WHERE THE POTENTIAL FOR LOCALLY HEAVY
RAINFALL AND FLOODING IS MOST EVIDENT THIS MORNING.
AS A COMPACT UPPER WAVE CONTINUES INTO THE OZARKS THROUGH THE DAY,
AND AN ATTENDANT SURFACE FRONT DROPS SOUTHWARD ACROSS THE AREA,
RAIN AND THUNDERSTORM CHANCES WILL LIKEWISE SHIFT INTO PORTIONS OF
CENTRAL AND SOUTHERN OKLAHOMA AND WESTERN-NORTH TEXAS THROUGHOUT
THE DAY. THIS WILL INCLUDE A RISK FOR SEVERE THUNDERSTORMS BY
LATE THIS AFTERNOON INTO EVENING ACROSS SOUTHERN OKLAHOMA AND
NORTH TEXAS. BOTH LARGE HAIL AND DAMAGING WIND GUSTS WILL BE
POSSIBLE WITH THE STRONGEST THUNDERSTORMS HERE.
DAYTIME TEMPERATURES WILL ONCE AGAIN BE STRONGLY MODERATED BY
ONGOING PRECIPITATION AND AREAS OF CLOUD COVER, ALONG WITH THE
BEGINNINGS OF AN INTRUDING COOLER AIRMASS (BEHIND THE FRONT). THE
PROGRESSION OF THE FRONT LOOKS TO OCCUR FASTER THAN PREVIOUS
FORECASTS WOULD INDICATE, WITH TEMPERATURES NOW EXPECTED TO
REMAIN IN THE 70S ALONG AND NORTH OF I-40. NEAR TRIPLE-DIGIT HEAT
IS LIKELY ACROSS WESTERN-NORTH TEXAS WITHIN A PRE-FRONTAL THERMAL
RIDGE.

SHORT TERM
(THURSDAY NIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 1258 AM CDT THU AUG 28 2025
RAIN SHOWER AND THUNDERSTORM POTENTIAL LOOKS TO CONTINUE AT LEAST ON
A SCATTERED BASIS INTO THURSDAY NIGHT/FRIDAY MORNING, ESPECIALLY
IN AREAS ALONG AND SOUTH OF INTERSTATE 40. WHILE A STRONG-TO-
SEVERE THUNDERSTORM OR TWO WILL REMAIN POSSIBLE DURING THIS TIME,
A PRIMARY RISK FOR LIGHTNING AND BRIEF HEAVY RAINFALL WILL
ACCOMPANY THIS ACTIVITY.
WHILE A FEW RESIDUAL RAIN SHOWERS WILL BE POSSIBLE ON FRIDAY MORNING
ACROSS SOUTHEASTERN OKLAHOMA, A VERY PLEASANT WEATHER DAY, FEATURING
MOSTLY DRY AND CLOUDY CONDITIONS ALONG WITH COOLER TEMPERATURES
(70S NORTH/CENTRAL; 80S SOUTH), IS CURRENTLY ADVERTISED. ATTENTION
WILL TURN TOWARDS WESTERN OKLAHOMA/WESTERN-NORTH TEXAS OVERNIGHT
INTO SATURDAY MORNING FOR OUR NEXT POTENTIAL ROUND OF
PRECIPITATION. LOW-MEDIUM (20-50%) PRECIPITATION CHANCE LOOKS TO
PERSIST INTO EARLY PORTIONS OF THE DAY ACROSS SOUTHWESTERN EXTENTS
OF THE FORECAST AREA. TEMPERATURES WILL REMAIN UNUSUALLY COOL ON
SATURDAY, A FEW DEGREES ON EITHER SIDE OF 80 ON AVERAGE.

NORTH TEXAS. ADDITIONAL EPISODES OF HIGH PLAINS ORIGINATING
ACTIVITY WILL BE POSSIBLE ACROSS WESTERN AND SOUTHERN PORTIONS OF
THE AREA ON SATURDAY NIGHT AND PERHAPS SUNDAY NIGHT (THOUGH
CHANCES DECREASE OVER EACH SUCCESSIVE NIGHT). TEMPERATURES WILL
BEGIN TO SLOWLY MODERATE INTO EARLY NEXT WEEK, THOUGH WILL
CONTINUE TO RUN SEVERAL DEGREES BELOW NORMAL FOR THE START OF
SEPTEMBER.
