Areas affected...Edwards Plateau to the Big Country in west TX

Concerning...Severe potential...Tornado Watch likely=20

Valid 101835Z - 102030Z

Probability of Watch Issuance...95 percent

SUMMARY...Severe storms are expected to initiate across the western
Edwards Plateau and Concho Valley. Very large to giant hail along
with an increasing tornado threat is expected into early evening,
especially across the Edwards Plateau vicinity. A tornado watch will
be issued by 21Z.

DISCUSSION...High-based cumulus development is ongoing across the
Permian Basin and Trans-Pecos, along the leading edge of stronger
large-scale ascent downstream of the northwest Mexico shortwave
trough. The warm-moist sector ahead of the west TX dryline continues
to destabilize, with moderate buoyancy prevalent towards central TX.
18Z FWD sounding sampled a pronounced EML with substantial MLCIN,
likely limiting initial severe potential to west of the residual
stratocumulus deck lingering over central TX.

Storm development should emanate out of the high-based cumulus
across the western Edwards Plateau and Concho Valley. With robust
southwesterly speed shear in the mid to upper levels, atop low-level southerlies, wind profiles will be conducive to supercells and
eventual upscale growth into bowing linear segments. The latter
should be favored with northern/northeast extent, with some
uncertainty on just how far north sustained supercell development
will occur into the TX Big Country.=20

The very large hail to giant hail threat, along with an increasing
tornado risk should tend to be centered on the Edwards Plateau where
larger buoyancy and more discrete supercell structures impinge on an
increasing low-level jet by early evening. This setup may yield a
couple long-track/intense supercells.
