   AREAS AFFECTED...WRN TX
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 609...
   
   VALID 060944Z - 061045Z
   
   THREAT FOR DAMAGING WINDS TO CONTINUE ACROSS ERN/SERN PARTS OF WW
   609 FOR THE NEXT HOUR...WHILE ISOLATED STRONG WIND GUSTS WILL BE
   POSSIBLE IN THE COLD POOL REGION.
   
   REGIONAL RADARS SHOWED THE STRONGEST STORMS WERE LOCATED OVER GARZA
   AND KENT COUNTIES WITH LATEST SURFACE OBSERVATIONS INDICATING WIND
   GUSTS APPROACHING SEVERE VALUES /47 KT GUST IN GARZA COUNTY NEAR
   09Z/.  THIS PORTION OF THE BROKEN LINE OF STORMS...WHICH EXTENDED
   FROM COTTLE COUNTY TO KENT COUNTY...SHOULD REACH NERN FISHER TO
   STONEWALL COUNTIES BY 10Z.  OBJECTIVE ANALYSES INDICATED WEAKER
   DOWNSTREAM INSTABILITY /EAST OF WW 609/...WITH SATELLITE IMAGERY
   SHOWING WARMING CLOUD TOPS...BOTH OF WHICH SUGGEST A DECREASING
   SEVERE THREAT DURING THE NEXT 1-2 HOURS.
   
   A THREAT FOR ISOLATED STRONG WIND GUSTS WILL BE POSSIBLE WITHIN THE
   COLD POOL REGION ASSOCIATED WITH HEAT BURST TYPE WIND GUSTS. THESE
   WIND GUSTS WILL BE THE RESULT OF STEEP MID LEVEL LAPSE RATES OVER
   THIS REGION AIDING IN AN INCREASE IN DOWNWARD VERTICAL ACCELERATION
   WITH POCKETS OF MID/UPPER LEVEL EVAPORATIVE COOLING IN THE
   CONVECTIVE CLOUD DEBRIS.
