CONCERNING...TORNADO WATCH 349...

VALID 292342Z - 300115Z

EXTREME INSTABILITY AND OUTFLOW/FRONT MERGER ACROSS THE SWRN
SECTIONS OF TORNADO WATCH 349 WILL MAINTAIN THE THREAT FOR DAMAGING
WINDS AND HAIL ACROSS PORTIONS OF THE TX GULF COAST THIS EVENING.

LATEST RADAR TRENDS SUGGEST VIGOROUS TO EXPLOSIVE TSTM DEVELOPMENT
CONTINUES ACROSS JIM WELLS...LIVE OAK...AND BEE COUNTIES WEST AND
NORTH OF CRP. A LARGE HP SUPERCELL WAS ALSO SPREADING SLOWLY SEWD
ACROSS THE NRN PORTION OF PADRE ISLAND. AN EXTENSIVE OUTFLOW
BOUNDARY EMANATES FROM THIS STORM AND EXTENDS SWD...WWD...AND THE
NWD. GIVEN MAGNITUDE OF INSTABILITY AND DEEP LAYER SHEAR ON THE
ORDER OF 30-35KT ENVIRONMENT WILL REMAIN FAVORABLE FOR SUPERCELLS.
SLOW APPROACH OF UPPER TROUGH AND NUMEROUS CELL/BOUNDARY
INTERACTIONS WILL FURTHER AID DEEP CONVECTION INTO THE EVENING WITH
THE CHANCE FOR VERY LARGE HAIL...HIGH WINDS...AND A TORNADO OR TWO.
