Areas affected...Parts of the TX Permian Basin/Edwards Plateau

Concerning...Tornado Watch 229...

Valid 060733Z - 060900Z

The severe weather threat for Tornado Watch 229 continues.

SUMMARY...Tornadoes remain possible near/south of the warm front.
Otherwise, a threat for large hail and localized severe gusts will
continue.

DISCUSSION...Extensive convection is ongoing early this morning
across parts of the TX Permian Basin and Edwards Plateau. While the
mode has become complex, a few supercells have persisted, with a
recent report of 2.5 inch hail in Crane County, TX. Convection may
continue to increase in coverage overnight, in response to an
eastward-moving mid/upper-level cyclone over the Southwest and
related strong low-level jet. 

Moderate to strong instability and very favorable deep-layer shear
will continue to support supercell potential overnight, though some
continued clustering of storms is possible, especially along an
eastward moving cold front. Large to very large hail and localized
severe gusts will continue to be a threat overnight with the
strongest storms. 

The environment remains conditionally favorable for tornadoes
near/south of a northwest-to-southeast oriented warm front, with
substantial low-level SRH continuing to be noted in the KDFX VWP.
Thus far, storms have tended to quickly move to the cool side of the
front and become elevated. However, it remains possible that ongoing
developing convection west of Del Rio could evolve into a supercell
that would pose a tornado threat in addition to the hail/wind
potential. Storms near the intersection of the warm front and
eastward-moving cold front/outflow could also pose some embedded
tornado potential. 

With some severe threat likely to persist beyond the 4 AM CDT
expiration time of WW 229, local watch extension and/or new watch
issuance will be possible later this morning.
