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.
