CONCERNING...TORNADO WATCH 264...
VALID 090256Z - 090430Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 264 CONTINUES.
SUMMARY...RISKS FOR LARGE HAIL...ISOLATED SEVERE WINDS AND A TORNADO
SHOULD REMAIN SPATIALLY CONFINED ALONG PARTS OF THE PECOS RIVER IN
FAR W TX...LIKELY SUBSIDING OVERNIGHT.
DISCUSSION...STRONG SUPERCELL ALONG THE PECOS RIVER IN LOVING/REEVES
COUNTIES OF TX HAS LARGELY EVOLVED AS THE DOMINANT UPDRAFT FROM A
FAMILY OF SUPERCELLS EARLIER OVER EDDY/LEA COUNTIES IN NM. WITH
GROUND CLUTTER INCREASING SUBSTANTIALLY ON THE MAF RADAR OVER THE
PAST HALF-HOUR AND LITTLE APPRECIABLE CHANGE TO THE LOW/DEEP-LAYER
WIND PROFILE DURING THE PAST FEW HOURS...IT APPEARS LIKELY THAT
INCREASING MLCIN WILL ULTIMATELY LEAD TO WEAKENING OF THIS INTENSE
UPDRAFT OVER THE NEXT FEW HOURS. UNTIL THAT OCCURS...LARGE HAIL AND
SEVERE WIND GUSTS WILL REMAIN LIKELY WITH POSSIBLY A TORNADO GIVEN
THE PRESENCE OF MIDDLE 60S SURFACE DEW POINTS.
