MESOSCALE DISCUSSION 2054
NWS STORM PREDICTION CENTER NORMAN OK
0337 PM CDT TUE SEP 09 2025
AREAS AFFECTED...FAR EASTERN NM INTO PARTS OF THE TX PANHANDLE/SOUTH
PLAINS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 092037Z - 092230Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...STRONG TO LOCALLY SEVERE STORMS ARE POSSIBLE LATE THIS
AFTERNOON INTO THE EVENING.
DISCUSSION...STORM INITIATION IS UNDERWAY ACROSS ROOSEVELT COUNTY,
NM AS OF 2030 UTC, WITH INCREASING CUMULUS NOTED FARTHER NORTH. IN
ADDITION TO THE ONGOING DEVELOPMENT, CONTINUED STRONG HEATING AND
WEAKENING OF MLCINH MAY EVENTUALLY RESULT IN ISOLATED STORM
DEVELOPMENT FARTHER EAST INTO PARTS OF THE TX PANHANDLE/SOUTH
PLAINS, NEAR A WEAK SURFACE CONFLUENCE ZONE.
INITIAL HIGH-BASED CONVECTION CLOSER TO THE NM/TX BORDER WOULD POSE
A THREAT OF LOCALIZED STRONG TO SEVERE GUSTS WITHIN THE DEEPLY MIXED
ENVIRONMENT. WHILE DEEP-LAYER SHEAR IS RELATIVELY MODEST, ISOLATED
HAIL CANNOT BE RULED OUT GIVEN THE PRESENCE OF STEEP MIDLEVEL LAPSE
RATES AND MLCAPE OF AROUND 1000-1500 J/KG. ANY STORMS THAT DEVELOP
OR MOVE FARTHER EAST COULD POSE A SOMEWHAT GREATER HAIL THREAT,
GIVEN THE PRESENCE OF RICHER LOW-LEVEL MOISTURE AND GREATER MLCAPE.
COVERAGE OF THE SEVERE THREAT IS EXPECTED TO REMAIN RATHER ISOLATED,
RENDERING THE NEED FOR A WATCH UNCERTAIN IN THIS AREA. HOWEVER,
WITHIN THE NORTHWESTERLY FLOW REGIME, ONLY A SLIGHT INCREASE IN
DEEP-LAYER SHEAR COMPARED TO WHAT IS CURRENTLY OBSERVED/ANALYZED
COULD SUPPORT POTENTIAL FOR A SUPERCELL OR TWO, AND OBSERVATIONAL
TRENDS WILL CONTINUE TO BE MONITORED REGARDING THE NEED FOR WATCH
ISSUANCE.
