ISSUED AT 1231 PM CDT THU AUG 28 2025
AN OUTFLOW BOUNDARY CONTINUES TO PUSH SOUTHWARD THIS MORNING AND IS
ROUGHLY LOCATED FROM NEAR MCALESTER TO ARDMORE TO WALTERS AND ALTUS
(AT 11:30 AM). SOME CLOUD ENHANCEMENT HAS BEEN NOTED ALONG THE
LEADING EDGE, BUT IS BEGINNING TO DECREASE ON THE WESTERN POTION OF
THIS BOUNDARY. ALTHOUGH THE BULK OF THE MORNING PRECIPITATION IS
CONFINED TO THE EASTERN THIRD OF OKLAHOMA, WIDELY SCATTERED
SHOWERS AND STORMS CONTINUE TO FORM, MAINLY EAST OF I-35.
A COLD FRONT IS MAKING A BETTER PUSH SOUTHWARD ACROSS THE TEXAS
PANHANDLE AND IS BECOMING BETTER DEFINED ACROSS PARTS OF WEST
CENTRAL AND SOUTHWESTERN OKLAHOMA (BETWEEN ERICK AND HOBART.
TEMPERATURES HAVE ALREADY SOARED INTO THE LOWER AND MID 90S
ACROSS WESTERN NORTH TEXAS.
SO THE BOTTOM LINE IS STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED TO
FORM ALONG A COLD FRONT/OUTFLOW BOUNDARY BY EARLY TO MID AFTERNOON.
THIS IS MAINLY EXPECTED TO BE ACROSS THE SOUTHERN THIRD OF OKLAHOMA
AND WESTERN NORTH TEXAS. WITH ONGOING CONVECTION ACROSS SOUTHCENTRAL
AND SOUTHEASTERN OKLAHOMA, THIS AREA MAY SEE SEVERE STORMS FIRST OR
AT LEAST AN INCREASE IN THUNDERSTORM INTENSITY. MODERATE TO STRONG
INSTABILITY AND MARGINAL SHEAR WILL SUPPORT THE RISK OF STRONG
DAMAGING WINDS/SOME LARGE HAIL AND VERY HEAVY RAINFALL. A MAJORITY
OF THE SEVERE CONVECTION SHOULD BE CONFINED TO NORTHERN TEXAS BY
EARLY EVENING.
CONVERGENT MID-LEVEL FLOW AND SUFFICIENT MOISTURE WILL SUPPORT A
CHANCE OF WIDELY SCATTERED SHOWERS AND A FEW STORMS NORTH OF THE
SURFACE BOUNDARY DURING THE EVENING AND OVERNIGHT HOURS.
SHORT TERM
(FRIDAY THROUGH SATURDAY NIGHT)
ISSUED AT 1231 PM CDT THU AUG 28 2025
ALTHOUGH A COLD FRONT IS EXPECTED TO PUSH INTO AT LEAST NORTHERN
TEXAS BY FRIDAY MORNING, PARTS OF SOUTH CENTRAL AND SOUTHEASTERN
OKLAHOMA WILL HAVE A CONTINUED CHANCE OF WIDELY SCATTERED SHOWERS
AND STORMS. ELSEWHERE, MAINLY DRY CONDITIONS ARE ANTICIPATED.
AFTERNOON HIGHS WILL BE WELL BELOW AVERAGE WITH TEMPERATURES RANGING
FROM THE MID 70S TO MID 80S (WESTERN NORTH TEXAS). NORTHEAST
SURFACE WINDS WILL BECOME EASTERLY DURING THE AFTERNOON AND EVENING.
BY LATE FRIDAY AFTERNOON AND EVENING, NUMEROUS SHOWERS AND STORMS
ARE EXPECTED TO DEVELOP WHERE RATHER DEEP, MOIST UPSLOPE FLOW WILL
OCCUR. WITH NORTHWEST FLOW ALOFT, SOME OF THIS PRECIPITATION IS
EXPECTED TO REACH AT LEAST THE WESTERN THIRD OF OKLAHOMA AND WESTERN
NORTH TEXAS BY LATE EVENING AND OVERNIGHT. SIMILAR TO CONVECTIVE
TRENDS OVER THE PAST SEVERAL DAYS, SOME OF THE SHOWERS AND
THUNDERSTORMS WILL LINGER THROUGH SATURDAY MORNING, ESPECIALLY
ACROSS WESTERN NORTH TEXAS.
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO DEVELOP
SATURDAY AFTERNOON AND EVENING OVER THE HIGHER TERRAIN OF NEW MEXICO
AND WESTERN TEXAS. RAIN CHANCES WILL REMAIN RATHER LOW ACROSS THE
EASTERN HALF OF OKLAHOMA SATURDAY EVENING AND OVERNIGHT, BUT SOME
STORMS WILL LIKELY IMPACT WESTERN OKLAHOMA AND WESTERN NORTH TEXAS
MAINLY DURING THE OVERNIGHT HOURS. SEVERE THUNDERSTORMS ARE NOT
EXPECTED FRIDAY THROUGH SATURDAY NIGHT, BUT AREAS OF HEAVY RAINFALL
MAY OCCUR WITH SOME OF THE STORMS.
