Areas affected...the eastern Texas Panhandle and western Oklahoma

Concerning...Severe Thunderstorm Watch 75...

Valid 172250Z - 180015Z

The severe weather threat for Severe Thunderstorm Watch 75
continues.

SUMMARY...The severe weather threat continues across severe
thunderstorm watch 75. The best chance for very large hail will be
with more discrete convection.

DISCUSSION...More widespread convection has started to develop along
the front with additional upscale growth expected through the
evening. Ahead of the front, a few more discrete supercells have
been dropping 1.5 to 2.0 inch hail. Expect these storms to be the
primary producers of very large hail for the next 2 to 3 hours since
this convection is expected to remain more discrete. This more
discrete convection will likely be absorbed into the main line of
storms as the storms along the front propagate eastward and
additional storms develop as  stronger forcing moves into the area.
As these storms continue to grow upscale, the threat will transition
from more of a hail threat to a damaging wind threat. 

In addition, storms along the front have had several reports of
tornadoes over the past 1 to 2 hours. Visual observations of the
tornadoes, radar imagery, and the vorticity rich low-level
environment along the surface front suggest these tornadoes are
likely forming from landspout processes. This threat may continue
over the next 1 to 2 hours but should wane later into the evening as
the cooling boundary layer and more widespread storm development
yields less favorable low-level lapse rates.
