Areas affected...TX Concho Valley

Concerning...Severe potential...Watch unlikely=20

Valid 240855Z - 241000Z

Probability of Watch Issuance...5 percent

SUMMARY...A short-duration severe wind/hail threat remains possible
during the pre-dawn hours across the Concho Valley.

DISCUSSION...Merging cells fostered upscale growth into an elevated
QLCS, with the southern portion showing a recent uptick in
intensity. West-TX Mesonet gusts had been sub-severe (up to 50 mph)
but not optimally located until it reached Sterling City where a 78
mph gust was recorded. This recent uptick may be related to the
merging of eastward-moving convective outflow with a prior
west-southwestward gravity wave evident in IR imagery after the
collapse of central TX convection earlier this morning.
MPAS-NSSL/GSL CAMs appear to have handled the intensification
scenario well, but both suggest it will be short-lived. Convection
should remain divorced from larger buoyancy across south/east TX and
southwesterly winds at 1-km AGL are expected to become veered
through sunrise with weakening low-level ascent.
