VALID 240330Z - 240530Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 164 CONTINUES. SUMMARY...A THREAT FOR SEVERE STORMS WILL CONTINUE LATE THIS EVENING AND POTENTIALLY INTO THE OVERNIGHT HOURS. DISCUSSION...SOME UPSCALE GROWTH IS UNDERWAY WITH A STORM CLUSTER SOUTHEAST OF AMARILLO, WITH EVIDENCE OF ACCELERATING AND EXPANDING OUTFLOW, AND DEVELOPMENT OF NEW STORMS TO THE NORTHEAST OF THE PRIMARY BOWING SEGMENT. A 79 MPH GUST WAS RECENTLY MEASURED NEAR SILVERTON, TX WITH THIS CLUSTER. THIS EVOLUTION IS LIKELY BEING AIDED BY A STRENGTHENING NOCTURNAL LOW-LEVEL JET, AS OBSERVED IN RECENT VWPS FROM KLBB. IN THE SHORT TERM, SUPERCELLS EMBEDDED WITHIN THIS CLUSTER WILL CONTINUE TO POSE A THREAT OF LARGE TO VERY LARGE HAIL AND PERHAPS A TORNADO, WHILE SOME INCREASE IN SEVERE-WIND POTENTIAL COULD ACCOMPANY THE GROWING COLD POOL. LONGER-TERM EVOLUTION OF THIS CLUSTER REMAINS UNCERTAIN, AS IT ENCOUNTERS GREATER DOWNSTREAM CINH WITH TIME. HOWEVER, IF THE COLD POOL CAN CONTINUE TO GROW AND ORGANIZE, AND POTENTIALLY ENCOMPASS ONGOING SEMI-DISCRETE CELLS TO THE EAST OF LUBBOCK, THEN SOME SEVERE THREAT WILL SPREAD INTO PARTS OF WESTERN NORTH TX AND SOUTHWEST OK LATE THIS EVENING INTO THE EARLY OVERNIGHT. DEPENDING ON SHORT-TERM OBSERVATIONAL TRENDS, LOCAL WATCH EXTENSION AND/OR NEW WATCH ISSUANCE MAY NEED TO BE CONSIDERED PRIOR TO THE MIDNIGHT CDT EXPIRATION TIME OF WW 164. ..DEAN/GUYER.. 04/24/2025 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...

VALID 240233Z - 240400Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 162 CONTINUES. SUMMARY...STRONG TO LOCALLY SEVERE STORMS MAY CONTINUE INTO LATE EVENING. DISCUSSION...A SMALL STORM CLUSTER IS ONGOING THIS EVENING TO THE SOUTHEAST OF FORT STOCKTON. A GRADUAL WEAKENING TREND HAS BEEN NOTED OVER THE LAST HOUR, POTENTIALLY DUE TO GRADUALLY INCREASING MLCINH WITH THE ONSET OF NOCTURNAL COOLING. HOWEVER, FAVORABLE BOUNDARY-LAYER MOISTURE BENEATH STEEP MIDLEVEL LAPSE RATES IS SUPPORTING MODERATE TO LOCALLY STRONG BUOYANCY (AS NOTED ON THE 00Z MAF AND DRT SOUNDINGS), WITH MLCAPE IN EXCESS OF 2000 J/KG. MEANWHILE, DEEP-LAYER SHEAR (AIDED BY A SUBTROPICAL JET) REMAINS FAVORABLE FOR ORGANIZED CONVECTION. SOME POTENTIAL REMAINS FOR AN UPTICK IN STORM INTENSITY THROUGH LATE EVENING, AIDED BY INCREASING LOW-LEVEL SOUTHEASTERLY FLOW (AS NOTED IN RECENT VWPS FROM KDFX). ANY NOTABLE UPTICK COULD BE ACCOMPANIED BY AT LEAST A LOW-PROBABILITY THREAT FOR ALL SEVERE HAZARDS, THOUGH IT REMAINS UNCERTAIN IF ORGANIZED CONVECTION CAN BECOME REESTABLISHED WITHIN AN INCREASINGLY CAPPED ENVIRONMENT. ..DEAN.. 04/24/2025 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...

SCATTERED STRONG TO SEVERE THUNDERSTORMS REMAIN POSSIBLE MAINLY OVER WEST TEXAS AND WESTERN KANSAS THIS EVENING. LARGE HAIL AND LOCALIZED WIND DAMAGE IS LIKELY. ...CENTRAL AND SOUTHERN PLAINS... SCATTERED SEVERE STORMS PERSIST THIS EVENING ACROSS MUCH OF WEST TX AND WESTERN KS, WITH A COMBINATION OF SPLITTING CELLS AND CLUSTERS. THESE STORMS WILL LIKELY PERSIST THROUGH THE EVENING DUE TO LITTLE IF ANY CAPPING, WITH ONLY A GRADUAL CONSOLIDATION/PRUNING IN COVERAGE. THE MOST UNSTABLE AIR WILL REMAIN FROM CENTRAL INTO NORTHWEST TX, WITH ISOLATED SIGNIFICANT HAIL THREAT. IN ADDITION TO LARGE HAIL, MERGING STORMS AND AGGREGATE OUTFLOWS MAY LOCALLY PRODUCE WIND DAMAGE. WINDS JUST OFF THE SURFACE WILL INCREASE IN SPEED TONIGHT, WHICH WILL MAINTAIN THETA-E ADVECTION AND INCREASE LOW-LEVEL SHEAR A BIT AS WELL.
