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.
