AREAS AFFECTED...SOUTHWEST INTO NORTH TEXAS

CONCERNING...SEVERE THUNDERSTORM WATCH 160...

VALID 102339Z - 110115Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 160
CONTINUES.

SUMMARY...HAIL AND DAMAGING WIND THREAT CONTINUES ACROSS THE WATCH
AREA...WITH SOME DEVELOPMENT EASTWARD TOWARD THE DFW METROPLEX AND
CENTRAL TEXAS I-35 CORRIDOR POSSIBLE OVER THE NEXT 1-2 HOURS.

DISCUSSION...CONTINUE WW 160.  SCATTERED THUNDERSTORMS NEAR MWL AND
MNZ HAVE BEGUN TO CONGEAL AND PROPAGATE SLOWLY
EASTWARD/SOUTHEASTWARD ALONG THE LEADING EDGES OF COLD POOLS
ESTABLISHED FROM PREVIOUS CONVECTION.  OVER THE NEXT COUPLE OF
HOURS...THESE STORMS ARE EXPECTED TO APPROACH AREAS NEAR/NORTHWEST
OF THE DFW METROPLEX AND ALSO CENTRAL TEXAS...WITH HAIL AND DAMAGING
WINDS LIKELY GIVEN THE VERY STRONG INSTABILITY /3500+ J/KG MUCAPE/
IN PLACE ACROSS THE REGION.  

FARTHER WEST...SCATTERED CONVECTION WILL CONTINUE TO PERCOLATE
NEAR/SOUTH OF SJT...WITH LEFT-MOVING CELLS NOTED ALONG THE WESTERN
FRINGES OF THE WW.  ALTHOUGH INSTABILITY IS SLIGHTLY LOWER IN THIS
REGION DUE TO LESSER BOUNDARY-LAYER MOISTURE CONTENT...HAIL AND
DAMAGING WIND GUSTS ARE POSSIBLE WITH THE STRONGER STORMS.  THIS
THREAT MAY DIMINISH SOME AFTER DARK AS NOCTURNAL BOUNDARY LAYER
COOLING REDUCES SURFACE-BASED INSTABILITY.
