NWS STORM PREDICTION CENTER NORMAN OK
0217 PM CDT TUE OCT 27 2026
AREAS AFFECTED...PARTS OF SOUTHEASTERN NEW MEXICO AND SOUTHWESTERN
TEXAS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 271917Z - 272145Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED STRONG TO SEVERE THUNDERSTORM DEVELOPMENT APPEARS
POSSIBLE BY 3-4 PM MDT INTO EARLY EVENING NEAR THE GUADALUPE AND
DAVIS MOUNTAINS VICINITY. THESE MAY POSE A RISK FOR LARGE HAIL AND
LOCALIZED STRONG SURFACE GUSTS.
DISCUSSION...DESTABILIZATION IS ONGOING IN RESPONSE TO CONTINUING
INSOLATION ALONG THE GUADALUPE AND DAVIS MOUNTAINS, WHERE SURFACE
DEW POINTS ARE IN THE UPPER 50S TO NEAR 60 F, BENEATH MODESTLY COOL
CYCLONIC MID-LEVEL FLOW. OROGRAPHIC FORCING, AIDED BY LIFT
ASSOCIATED WITH WEAK LOW-LEVEL WARM ADVECTION, IS ALREADY SUPPORTING
THE INITIATION OF ISOLATED THUNDERSTORM DEVELOPMENT. THIS IS LIKELY
TO CONTINUE INTO EARLY EVENING.
BENEATH 30-40+ KT WEST-SOUTHWESTERLY AROUND 7-8 KM AGL AND HIGHER,
DEEP-LAYER SHEAR NEAR THE HIGHER TERRAIN IS STRONG, WITH ELONGATED
HODOGRAPHS. THIS MAY SUPPORT THE OCCASIONAL EVOLUTION OF ISOLATED
SUPERCELL STRUCTURES WITH POTENTIAL TO PRODUCE LARGE HAIL, IN THE
PRESENCE OF THERMODYNAMIC PROFILES WITH STEEP LOWER/MID-TROPOSPHERIC
LAPSE RATES SUPPORTING CAPE IN EXCESS OF 1500 J/KG.
IT REMAINS UNCLEAR HOW FAR EAST OF THE HIGHER TERRAIN ACTIVITY WILL
DEVELOP. INFLUENCED BY GENERALLY WEAK LOWER TO MID-TROPOSPHERIC
WIND FIELDS, VEERING WITH HEIGHT, STORM MOTIONS MAY REMAIN MODEST TO
SLOW, WITH A TENDENCY TO PROPAGATE EAST/SOUTHEASTWARD.
