Areas affected...South-central Texas...Middle Texas Coastal Plain
Concerning...Severe Thunderstorm Watch 179...180...
Valid 282315Z - 290115Z
The severe weather threat for Severe Thunderstorm Watch 179, 180
continues.
SUMMARY...A wind-damage and large hail threat will likely develop
across parts of south-central Texas and across the middle Texas
Coastal Plain. New weather watch issuance will likely be needed over
the next hour or so.
DISCUSSION...A continuous line of severe storms is currently located
from just north of San Antonio northeastward to near College
Station. Moderate to strong instability ahead of the line, along
with a strengthening 30 to 40 knot low-level jet, will continue to
sustain a severe threat over the next few hours. The line is
forecast to move southeastward along a gradient of moderate
instability, crossing the middle Texas Coastal Plain this evening.
The primary threats, associated with the stronger parts of the line,
will be wind damage and large hail. As the line moves southeastward
and approaches the edge of WW 179 and WW 180, a new weather watch
will need to be issued across parts of the Texas Coastal Plain.
Further to the east across the Houston area, a stout cap is in place
and instability is weak. For these reasons, the severe threat is
expected to be more isolated in the Houston area.
