Areas affected...portions of southeastern Oklahoma into northeastern
Texas and far western Arkansas

Concerning...Severe Thunderstorm Watch 70...

Valid 020345Z - 020515Z

The severe weather threat for Severe Thunderstorm Watch 70
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 70. The main severe threat exists across northern portions of
the watch as a line of storms approaches from the west. Damaging
gusts are the main threat, though a tornado cannot be ruled out.

DISCUSSION...The earlier QLCS with embedded supercells across
northern TX has diminished in intensity given increasing inhibition.
However, a pronounced QLCS is in progress across central OK, and
this convection may move into Severe Thunderstorm Watch 70 over the
next few hours with a damaging gust threat. Portions of the watch
across eastern OK into western AR will most likely experience this
QLCS later this evening. It is unclear how far south the QLCS will
build into TX, so the severe threat is more conditional across the
TX portion of the watch. Regional VADs, 03Z mesoanalysis, and RAP
forecast soundings all show elongated hodographs with decent
low-level curvature. However, CINH is increasing above the boundary
layer given nocturnal cooling, tempering the tornado threat.
Nonetheless, a tornado cannot be completely ruled out if a QLCS
circulation can ingest any surface-based parcels.
