Areas affected...over northeast Texas and into far southwest
Arkansas

Concerning...Severe potential...Watch unlikely

Valid 202334Z - 210200Z

Probability of Watch Issuance...20 percent

SUMMARY...A severe storm or two may affect parts of northeast Texas
and vicinity this evening. Locally damaging gusts along with hail
over 1.00" diameter may occur.

DISCUSSION...Surface analysis shows a moist air mass over eastern
TX, east of a cold front and south of a warm front which is nearly
stationary. Surface winds are generally weak across the moist sector
with little surface pressure gradient. This weakness extends up to
850 mb as well, where speeds are on the order of 20-25 kt.

While cool midlevel temperatures remain over the area, the primary
trough continues to eject northeastward from the TX Panhandle into
western OK, with strong midlevel warming to the south. East of this
wave, height tendencies are forecast to remain rather neutral.
Still, moderate mid and high level southwesterlies are resulting in
effective shear around 50 kt. These elongated hodographs
conditionally favor a few longer lived cells off the cold front.

Areas of stronger cells currently extend from Ellis County into
Limestone/Falls Counties. The Ellis County complex is near the warm
front, and may persist as it rides along that boundary, with
enhanced ascent and gusty wind potential.
