1141 PM CDT Fri Mar 15 2024
Areas affected…South Texas
Concerning…Severe Thunderstorm Watch 55…
Valid 160441Z – 160645Z
The severe weather threat for Severe Thunderstorm Watch 55
continues.
SUMMARY…A threat for large hail and wind damage is likely to
continue for a few more hours across south Texas.
DISCUSSION…The latest hi-resolution radar from Corpus Christi
shows a large supercell to the southeast of Laredo. This storm is
located along the northern edge of a pocket of moderate to strong
instability, where the RAP has MLCAPE in the 2000 to 3000 J/kg
range. The storm appears to be supported by a large-scale ascent
associated with a subtle shortwave trough evident on water vapor
imagery. Lift associated with the trough, steep mid-level lapse
rates, and moderate deep-layer shear will likely continue to be
favorable for a severe threat as this storm moves eastward across
south Texas, and with additional cells that develop within the small
cluster. A potential for large hail and wind damage is expected to
persist for a few more hours.
