Areas affected...Southwest/West Central Texas

Concerning...Severe Thunderstorm Watch 7...

Valid 160036Z - 160130Z

The severe weather threat for Severe Thunderstorm Watch 7 continues.

SUMMARY...Severe threat continues across much of the eastern and
southern portions of WW07.  Large hail and locally damaging winds
are the primary threats.

DISCUSSION...Pre-frontal squall line is advancing steadily eastward
across ww07 at roughly 30kt.  A few bowing line segments are
embedded along the squall line and locally damaging winds,
especially over Menard county, could be noted with these features.
At the southern end, a severe supercell will soon move out of
Edwards county into Real county and this storm is likely producing
very large hail.

00z sounding from DRT exhibits steep low-midlevel lapse rates with
SBCAPE on the order of 1200 J/kg.  With new storms developing along
the primary cold front over Val Verde county this activity should
continue to mature and likely produce large hail.
