0341 PM CDT MON JUN 01 2026
AREAS AFFECTED...MUCH OF WESTERN KANSAS
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 012041Z - 012315Z
PROBABILITY OF WATCH ISSUANCE...60 PERCENT
SUMMARY...THE AREA IS BEING MONITORED FOR INCREASING SEVERE
POTENTIAL INTO THIS EVENING. PRIMARY CONCERNS WILL BE SEVERE WIND
GUSTS AND LARGE HAIL. TIMING OF A POTENTIAL WATCH REMAINS UNCERTAIN.
DISCUSSION...BOUNDARY-LAYER CUMULUS HAS BEEN GRADUALLY ATTEMPTING TO
DEEPEN WITHIN A ZONE OF CONFLUENT/UPSLOPE LOW-LEVEL FLOW IN WESTERN
KS, THOUGH WEAK/NEGLIGIBLE LARGE-SCALE FORCING FOR ASCENT AND
LINGERING INHIBITION HAVE LIMITED DEEPER DEVELOPMENT THUS FAR.
HOWEVER, CONTINUED ATTEMPTS MAY BE ERODING THE CAP AND COULD SUPPORT
ISOLATED STORM DEVELOPMENT OVER THE NEXT COUPLE HOURS.
THE GLD VWP IS SAMPLING DEEP/ENHANCED SOUTHEASTERLY FLOW VEERING TO
SOUTHWESTERLY MIDLEVEL WINDS (AROUND 40 KT OF EFFECTIVE SHEAR).
WHILE DEVELOPMENT WITHIN THE CONFLUENCE ZONE STILL REMAINS
UNCERTAIN, THIS WIND PROFILE COUPLED WITH STEEP DEEP-LAYER LAPSE
RATES AND A WARM/MOIST PBL WILL CONDITIONALLY SUPPORT ORGANIZED
STORMS TO INCLUDE SUPERCELLS. ANY STORMS THAT CAN DEVELOP/MATURE
WILL POSE A RISK OF LARGE HAIL AND SEVERE WIND GUSTS, THOUGH A BRIEF
TORNADO CANNOT BE ENTIRELY RULED OUT GIVEN THE PRESENCE OF ENHANCED
STREAMWISE VORTICITY FOR ANY ESTABLISHED STORMS.
ADDITIONAL THUNDERSTORMS EVOLVING OUT OF SOUTHEAST CO MAY EVENTUALLY
MOVE INTO THIS ENVIRONMENT AS WELL, WHICH WOULD ALSO BE CAPABLE OF
SEVERE WIND GUSTS AND HAIL. WHILE THE OVERALL CONVECTIVE SCENARIO
REMAINS A BIT UNCERTAIN, THE AREA IS BEING MONITORED FOR A POSSIBLE
WATCH ISSUANCE.
