Areas affected...East Texas

Concerning...Severe Thunderstorm Watch 151...

Valid 081721Z - 081845Z

The severe weather threat for Severe Thunderstorm Watch 151
continues.

SUMMARY...A severe threat is likely to continue this afternoon
across parts of east Texas. Wind damage, hail and possibly a tornado
may occur with the stronger parts of a squall-line. Weather watch
issuance will be needed to the east of WW 151.

DISCUSSION...The latest radar imagery shows a linear MCS across the
eastern Texas Hill Country. A moist airmass is located ahead of the
MCS with surface dewpoints in the lower 70s F. The RAP is estimating
 MLCAPE values across east Texas in the 1500 to 2500 J/kg range. The
MCS will continue to track eastward along a gradient of instability
at about 35 kts. The eastward motion combined with steepening
low-level lapse rates and moderate deep-layer shear will continue a
severe threat. Wind damage will be the greatest threat although, a
tornado can not be ruled out with rotating elements within the line.
Hail will also be possible with the stronger updrafts.
