SEVERE THREAT -- MAINLY IN THE FORM OF LARGE HAIL -- CONTINUES
ACROSS THE WW AREA.

COLD FRONT CONTINUES PUSHING SWD/SSWWD ACROSS WW...SUPPORTING
REDEVELOPMENT OF STORM UPDRAFTS WITHIN SMALL CLUSTER OF SEVERE
STORMS OVER CENTRAL TX.  MEANWHILE...NEW STORMS CONTINUE TO DEVELOP
N OF FRONT ACROSS SRN PORTIONS OF THE SOUTH PLAINS INTO THE
TRANSPECOS REGION.

MODERATE INSTABILITY PERSISTS ACROSS THIS REGION...AND PRONOUNCED
VEERING WITH HEIGHT -- PARTICULARLY N OF FRONT -- IS CONTRIBUTING TO
SHEAR SUFFICIENT FOR SUPERCELL STORMS. THIS IS CONFIRMED BY EVENING

PERSIST...AND PERHAPS INCREASE IN COVERAGE AS LOW-LEVEL JET
STRENGTHENS OVER THE NEXT COUPLE OF HOURS.
