Areas affected...TX Big Country into the Edwards Plateau

Concerning...Severe Thunderstorm Watch 153...

Valid 280421Z - 280615Z

The severe weather threat for Severe Thunderstorm Watch 153
continues.

SUMMARY...Broken squall line will advance east with an attendant
risk for wind/hail.

DISCUSSION...Latest satellite imagery clearly depicts large-scale
ascent spreading across the southern high Plains late this evening.
Robust, deep convection has evolved along the dryline south of I-20
into the Edwards Plateau. A broken squall line, with embedded
supercells, will propagate east into a region characterized by
MLCAPE on the order of 3000 J/kg, and deep-layer shear more than
strong enough to maintain organized updrafts. Latest radar data
suggests large hail is likely with the strongest updrafts, and
strong winds can be expected, especially with bowing segments. This
activity will progress steadily east across the remainder of the
watch into the pre-dawn hours.
