AREAS AFFECTED...N TX

CONCERNING...SEVERE THUNDERSTORM WATCH 329...

VALID 251714Z - 251845Z

DAMAGING WIND POTENTIAL WILL LIKELY INCREASE FOR PARTS OF N TX
INCLUDING PORTIONS OF THE DALLAS-FORT WORTH METROPLEX EARLY THIS
AFTN ALONG WITH THE THREAT FOR LARGE HAIL.

SWRN PART OF THE ELEVATED TSTM CLUSTER OVER WRN N TX APPEARS TO BE
APPROACHING THE NW-SE ORIENTED BOUNDARY SITUATED ACROSS THE DFW AREA
SEWD INTO CNTRL LA.  THIS IN COMBINATION WITH STRONG INSOLATION
ACROSS N TX HAS INCREASED THE PROBABILITY THAT MORE UNSTABLE
BOUNDARY LAYER PARCELS WILL BE INGESTED INTO THE UPDRAFTS.  THIS
PROCESS IS LIKELY TO CONTINUE THROUGH THIS AFTN...AS CINH IS ERODED
VIA DIABATIC HEATING AND ENHANCED FORCING ALONG THE COLD POOL.

TSTM CLUSTER ORIENTATION HAS ALSO BECOME MORE LINEAR SINCE
MID-MORNING...BECOMING MORE NORMAL TO THE WNWLY FLOW REGIME.  AS THE
TRAILING STRATIFORM RAIN SHIELD EXPANDS AND STORMS BECOME
SUBSTANTIALLY ROOTED INTO THE BOUNDARY LAYER...DAMAGING WINDS MAY
RESULT FROM THE BOWING LINE SEGMENTS.  STRONGEST TSTMS SHOULD TRACK
SEWD NEAR/N OF THE  METROPLEX BY 18-19Z. AS THE STORMS
MATURE...FORWARD SPEED MAY INCREASE AND STORMS MAY TEND TO DEVELOP
ON THE SWRN FLANK OF THE LINE...INTO THE MORE UNSTABLE ENVIRONMENT
LOCATED OVER NCNTRL TX.
