AREAS AFFECTED...PARTS OF SOUTH-CENTRAL AND SOUTHEAST TX

CONCERNING...TORNADO WATCH 210...

VALID 251910Z - 252045Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 210 CONTINUES.

SUMMARY...THE THREAT FOR TORNADOES...DMGG WINDS...AND LARGE HAIL
PERSISTS...ESPECIALLY ACROSS THE ERN HALF OF TORNADO WATCH 210.
AREAS TO THE EAST OF TORNADO WATCH 210 ARE ALSO BEING MONITORED FOR
A POSSIBLE WATCH LATER THIS AFTERNOON.

DISCUSSION...CURRENT RADAR TRENDS SHOW A PERSISTENT SUPERCELL
CLUSTER ACROSS BURNET COUNTY MOVING INTO TRAVIS/WILLIAMSON COUNTIES
TX...UNDERGOING SEVERAL INTERACTIONS WITH ANCILLARY CELL DEVELOPMENT
WITHIN LOW-LEVEL WAA REGIME. THE ENVIRONMENT REMAINS FAVORABLE FOR
SUPERCELL/TORNADO DEVELOPMENT...WITH THE INFLUX OF RICH
BOUNDARY-LAYER MOISTURE...LOW LCLS...AND 100-200 M2/S2 OF 0-1 KM
SRH...GIVEN THE ABILITY FOR STORMS TO REMAIN SEMI-DISCRETE. WEAKER
CONVECTION DEVELOPING VIA LOW-LEVEL WAA ALSO HAS DISPLAYED
INTERMITTENT/BRIEF ROTATION.

TRENDS WILL BE MONITORED AS PRIMARY SVR THREAT APPROACHES ERN EDGE
OF TORNADO WATCH 210 FOR A POSSIBLE NEW WW INTO SOUTHEAST TX.
CONSOLIDATION WITH SRN EDGE OF QLCS ACROSS CNTRL TX IS ALSO POSSIBLE
WITHIN THE NEXT COUPLE HRS...WHICH WOULD FAVOR AN INCREASING DMGG
WIND THREAT.
