Areas affected...TX South Plains and Big Country

Concerning...Severe Thunderstorm Watch 252...

Valid 012240Z - 020045Z

The severe weather threat for Severe Thunderstorm Watch 252
continues.

SUMMARY...Severe threat continues across ww252.

DISCUSSION...Mid-level short-wave trough is ejecting northeast
across the TX South Plains early this evening. High-level flow is
strongly diffluent across the southern Plains and this is aiding a
small cluster of organized convection across the Big Country. A weak
MCV appears to be evolving over Stonewall County which may also
contribute to this activity advancing a bit farther downstream
before it begins to weaken. Additionally, longer-lived supercell is
tracking across Jones into Shackelford County with large hail and
wind. Latest diagnostic data suggests weaker buoyancy immediately
downstream of this activity which favors some weakening. Otherwise,
isolated thunderstorms may continue to develop along the
convectively-reinforced boundary draped across northern Portions of
MAF CWA.
