Areas affected...Texas Coastal Plain

Concerning...Severe Thunderstorm Watch 180...181...182...

Valid 290128Z - 290330Z

The severe weather threat for Severe Thunderstorm Watch 180, 181,
182 continues.

SUMMARY...A severe threat is likely to continue across the Texas
Coastal Plain over the next couple of hours. Wind damage and large
hail will be the primary threats.

DISCUSSION...The latest WSR-88D radar imagery from San Antonio and
Houston show a broken line of strong to severe storms, located from
near Laredo northeastward to west of the Houston area. The line is
near an axis of moderate to strong instability, with surface
dewpoints ahead of the line generally in the lower 70s F. In
addition to the moist airmass, moderate deep-layer shear is present.
The Corpus Christi WSR-88D VWP has about 45 knots of 0-6 km shear,
with some directional shear evident in the low to mid-levels. This
will likely be enough to support a severe threat for several more
hours. Although supercells with wind damage and large hail will be
possible, the more dominant threat is expected to be wind damage
associated with the faster moving line segments. The severe threat
will move into the immediate coastal areas later this evening.
