Areas affected...west Texas

Concerning...Severe Thunderstorm Watch 172...

Valid 160209Z - 160345Z

The severe weather threat for Severe Thunderstorm Watch 172
continues.

SUMMARY...Threat for isolated damaging wind and large hail will
persist across the remainder of WW 172 in western TX next couple
hours, after which the threat is expected to diminish. Another WW is
not anticipated after 04Z, but current WW can be locally extended if
needed.

DISCUSSION...A broken line of storms continue moving slowly east
from the western TX Panhandle southward through western TX.
Strongest storms are in the Lubbock CWA while the storms farther
north have shown a weakening trend. A strengthening southerly
low-level jet may help to maintain storms farther east into west TX
next few hours where the atmosphere remains moderately unstable.
However, a stabilizing boundary layer and relatively weak mid-level
flow suggest the overall severe threat should gradually diminish
toward late evening.
