Areas affected...Red River Valley toward the Arklatex
Concerning...Severe potential...Watch unlikely 
Valid 281855Z - 282130Z
Probability of Watch Issuance...20 percent
SUMMARY...A corridor of stronger storms may yield locally severe
gusts or marginal hail through the afternoon.
DISCUSSION...A front enhanced by ongoing convection currently
extends from southwest OK toward the Red River and near Texarkana,
and continues to show gradual southward progress. Warm/moist air
south of this front is spreading northeastward across TX and toward
the front, with renewed thunderstorm development noted northwest of
Paris, TX.
While midlevel lapse rates are not particularly steep, low 70s F
dewpoints and temperatures near 90 F are contributing to at least
1500 J/kg MLCAPE. Midlevel west to northwest flow of 30-35 kt atop
the frontal zone results in effective deep-layer shear near 35 kt. 
As such, the storms near Paris are expected to persist, and may grow
upscale over the next few hours. Locally strong to severe gusts may
occur, along with hail generally at or below 1.00".
