0514 PM CDT WED JUN 24 2026
AREAS AFFECTED...PORTIONS OF FAR SOUTHERN OKLAHOMA INTO FAR NORTHERN
TEXAS...EXTREME SOUTHWESTERN ARKANSAS AND EXTREME NORTHWESTERN
LOUISIANA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 242214Z - 242345Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...AN ISOLATED SEVERE WIND/HAIL RISK EXISTS ALONG A
BAROCLINIC BOUNDARY UNDER THE CONDITION THAT STORMS CAN INITIATE AND
ORGANIZE.
DISCUSSION...A QUASI-STATIONARY BAROCLINIC BOUNDARY CURRENTLY
RESIDES JUST NORTH OF THE RED RIVER ALONG MUCH OF FAR SOUTHERN OK.
DESPITE WEAK SYNOPTIC FORCING FOR ASCENT, EXTREME BUOYANCY (4000+
J/KG MLCAPE) AND MINIMAL MLCINH WITH 40+ KTS OF EFFECTIVE BULK SHEAR
IS COINCIDING WITH THE BOUNDARY PER 21Z MESOANALYSIS. AS SUCH, ANY
STORM THAT MANAGES TO DEVELOP AND SUSTAIN ITSELF WILL HAVE THE
POTENTIAL TO PRODUCE SEVERE WIND/HAIL OR PERHAPS A TORNADO. A STORM
HAS RECENTLY INITIATED OVER ATOKA COUNTY, OK, SUGGESTING THAT
SURFACE-BASED HEATING IS STRONG ENOUGH TO SUPPORT ADDITIONAL
ISOLATED ATTEMPTS AT CONVECTIVE INITIATION ALONG THIS BOUNDARY OVER
THE NEXT SEVERAL HOURS. THE SEVERE THREAT SHOULD REMAIN ISOLATED
GIVEN OVERALL LACK OF DEEP-LAYER ASCENT.
