Areas affected...Texas and Oklahoma Panhandles...and Northwest
Oklahoma

Concerning...Tornado Watch 327...

Valid 172229Z - 180030Z

The severe weather threat for Tornado Watch 327 continues.

SUMMARY...The wind-damage and tornado threats are expected to
continue, and will likely increase from the Oklahoma Panhandle and
northern Texas Panhandle into northwest Oklahoma over the next few
hours.

DISCUSSION...A line of strong to severe thunderstorms is currently
ongoing across far eastern Colorado and the far western Oklahoma
Panhandle. A wind damage and tornado threat will likely continue
with this line as it accelerates eastward across the Oklahoma
Panhandle over the next couple of hours. Discrete cells are also
expected to continue developing further to the east from the eastern
Oklahoma Panhandle and northeastern Texas Panhandle into northwest
Oklahoma. Due to strong instability, moderate deep-layer shear and
steep mid-level lapse rates evident on RAP forecast soundings, these
storms should be supercellular with a threat for large hail.
Hailstones greater than 2 inches in diameter will be possible with
supercells. A tornado threat will also exist, especially with cells
that remain discrete in advance of the fast-moving linear MCS.
