AREAS AFFECTED...TX HILL COUNTRY

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 082342Z - 090115Z

LARGE HAIL/DAMAGING WIND THREAT WILL PERSIST UNTIL ABOUT 01Z ACROSS
THE HILL COUNTRY...BUT LIMITED TEMPORAL/SPATIAL NATURE OF THREAT
WILL PRECLUDE AN ADDITIONAL WW.

WWD MOVING OUTFLOW FROM SE TX MCS WILL COLLIDE WITH SURFACE
TROUGH/DRYLINE ACROSS THE HILL COUNTRY IN THE NEXT 1-2 HOURS IN THE
AREA NE THROUGH S OF JCT.  A NARROW CORRIDOR OF STRONG INSTABILITY
HAS BEEN MAINTAINED BETWEEN THESE TWO BOUNDARIES...WHERE THE THREAT
FOR LARGE HAIL/DAMAGING WINDS WILL PERSIST WITH SUPERCELLS. 
HOWEVER...THE SEVERE THREAT IS EXPECTED TO DIMINISH BY ABOUT 01Z AS
THE COOL/RELATIVELY STABLE OUTFLOW AIR MASS OVERTAKES THE STALLED
DRYLINE/TROUGH FROM THE E.
