NWS STORM PREDICTION CENTER NORMAN OK
0126 AM CDT SUN JUN 15 2025
AREAS AFFECTED...PARTS OF NORTH CENTRAL/CENTRAL OK
CONCERNING...SEVERE THUNDERSTORM WATCH 417...
VALID 150626Z - 150830Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 417
CONTINUES.
SUMMARY...THUNDERSTORM DEVELOPMENT IS LIKELY TO CONTINUE THROUGH THE
REMAINDER OF THE NIGHT, WITH POTENTIAL TO ORGANIZE AND BEGIN TO
PRODUCE STRONG TO SEVERE WIND GUSTS, PARTICULARLY TO THE NORTH OF
THE GREATER OKLAHOMA CITY AREA DURING THE NEXT COUPLE OF HOURS.
DISCUSSION...CONVECTION LIKELY REMAINS ROOTED WITHIN FORCING FOR
ASCENT ASSOCIATED WITH LOWER/MID-TROPOSPHERIC WARM ADVECTION, NEAR
THE NOSE OF A MODEST SOUTHWESTERLY NOCTURNAL LOW-LEVEL JET. THIS IS
OCCURRING ABOVE A BOUNDARY-LAYER AIR MASS SUBSTANTIALLY IMPACTED BY
PRIOR CONVECTION, WITH LITTLE SUBSTANTIVE SURFACE COLD POOL
STRENGTHENING EVIDENT WITH ONGOING ACTIVITY.
STRONGEST CONTINUING THUNDERSTORM DEVELOPMENT THROUGH THE NEXT
SEVERAL HOURS APPEARS LIKELY TO BECOME INCREASINGLY FOCUSED ALONG
THE WESTERN FLANK OF THE COMPOSITE OUTFLOW, ROUGHLY EAST OF ALVA
INTO AREAS NORTH OF OKLAHOMA CITY OK, WHERE ELEVATED (SOUTHWESTERLY)
UPDRAFT INFLOW WILL REMAIN MOST UNSTABLE. THIS MAY REMAIN
CHARACTERIZED BY CAPE IN EXCESS OF 2000 J/KG. ALTHOUGH THIS IS
EMBEDDED WITHIN WESTERLY DEEP-LAYER MEAN FLOW ON THE ORDER OF 10 KT,
VEERING PROFILES FROM SOUTHWESTERLY TO NORTHWESTERLY IN
LOWER/MID-LEVELS MAY CONTINUE TO SUPPORT EVOLVING SUPERCELL
STRUCTURES.
IT STILL APPEARS POSSIBLE THAT CONVECTION CURRENTLY INTENSIFYING
BETWEEN ENID AND CHANDLER COULD UNDERGO SUBSTANTIVE FURTHER UPSCALE
GROWTH, AND PERHAPS BECOME ACCOMPANIED BY A MORE PROMINENT SOUTHWARD
PROPAGATING SURFACE COLD POOL WITH INCREASING POTENTIAL TO PRODUCE
STRONG TO SEVERE WIND GUSTS BY 08-10Z.
