NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...CENTRAL TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 191846Z - 192045Z

...THUNDERSTORMS WILL SLOWLY INCREASE ACROSS PORTIONS OF CENTRAL TX.
 SEVERE THUNDERSTORM WATCH MAY BE NEEDED LATER..

RECENT LIGHTNING/RADAR DATA INDICATE THUNDERSTORMS ARE GRADUALLY
INCREASING ACROSS WRN PORTIONS OF THE HILL COUNTRY SOUTH OF JCT. 
THIS ACTIVITY APPEARS TO BE DEVELOPING ALONG LEADING EDGE OF
STRONGER FORCING/STEEP LAPSE RATES...JUST WEST OF HIGHER BOUNDARY
LAYER MOISTURE.  AS THIS ACTIVITY MATURES...IT SEEMS REASONABLE THAT
A GRADUAL INCREASE WILL OCCUR AS IT SPREADS DOWNSTREAM ALONG
PREEXISTING BOUNDARY...ESPECIALLY AS AIRMASS HEATS/MOISTENS.  HAIL
SHOULD DEVELOP WITHIN STRONGER CELLS AS THEY INGEST HIGHER
INSTABILITY LATER THIS AFTERNOON.
