Areas affected...West-central into northeast OK

Concerning...Severe Thunderstorm Watch 649...

Valid 122231Z - 130000Z

The severe weather threat for Severe Thunderstorm Watch 649
continues.

SUMMARY...The threat for isolated damaging wind gusts will continue
into the early evening.

DISCUSSION...A broken line of thunderstorms is ongoing from
west-central into northeast OK as of 2230Z. Convection has largely
remained disorganized thus far, and observed wind gusts over the
last hour from ASOS and the OK mesonet have been less than 35 kt.
This region is on the southern fringe of stronger midlevel flow
associated with the upper trough over the central/northern Plains,
and as convection continues to propagate southward, effective shear
will tend to decrease and no substantial uptick in convective
organization is expected. However, occasional wet microbursts and/or
stronger gusts along the leading edge of the cold pool will pose
some threat for severe wind into the early evening. The greatest
relative short-term threat will likely be with the forward
propagating cluster moving from Noble into Pawnee/Osage counties in
OK.
