Areas affected...parts of northeast TX...northwest LA...south
AR...north MS...and southwest TN

Concerning...Severe potential...Watch possible=20

Valid 081838Z - 082045Z

Probability of Watch Issuance...40 percent

SUMMARY...A few damaging gusts are possible across parts of far
northeast Texas, far northwest Louisiana, southern Arkansas, western
Tennessee, and northern Mississippi. Trends are being monitored for
a watch in the next couple hours.

DISCUSSION...Convection is ongoing near a remnant MCV and boundary
across central Arkansas and northern Mississippi. Ahead and south of
the convection, temperatures are in the low 90s F and dewpoints are
in the mid 70s, yielding a moist and strongly unstable troposphere.
However, short-term RAP forecast profiles in the region show weak
low-level and deep-layer shear, meaning multicell clusters with
water-loaded downdrafts should dominate in the area. Therefore, wind
damage should be the primary threat with these storms, and a
preferred area of clustering and wind damage may occur along the
boundary near I-40. With time storms should cluster and move off to
the east and southeast.
