AREAS AFFECTED...SOUTH CENTRAL TX

CONCERNING...TORNADO WATCH 259...

VALID 290414Z - 290545Z

...SEVERE THREAT IS INCREASING ACROSS SOUTH CENTRAL TX...WW WILL
LIKELY BE ISSUED JUST SOUTH OF WW259...

LATEST DIAGNOSTIC DATA SUGGESTS LOW LEVEL CONVERGENCE WILL PROVE
SUFFICIENT IN FORCING BOUNDARY LAYER PARCELS TO THEIR LFC ALONG
ADVANCING WIND SHIFT.  RADAR TRENDS SUPPORT THIS WITH SWWD
DEVELOPMENT ALONG PRE-FRONTAL BOUNDARY INTO NERN MEXICO WEST OF DRT.
 FORECAST SOUNDINGS SUGGEST STRONG CAP JUST SOUTH OF CURRENT WW259
WILL BE REMOVED THROUGH VERTICAL ASCENT/COOLING.  DEVELOPING SQUALL
LINE WILL LIKELY ADVANCE INTO PORTIONS OF SOUTH CENTRAL TX NOT
CURRENTLY COVERED BY TORNADO WATCH.  FOR THIS REASON WILL LIKELY
ISSUE ANOTHER SMALL WATCH TO ACCOUNT FOR THIS EVOLUTION.
