Areas affected...parts of eastern Arkansas and into western
Tennessee and northern Mississippi

Concerning...Severe Thunderstorm Watch 352...

Valid 181848Z - 182045Z

The severe weather threat for Severe Thunderstorm Watch 352
continues.

SUMMARY...Local severe risk continues across parts of eastern
Arkansas; as storms gradually spread across the river into parts of
western Tennessee and northern Mississippi, local severe risk will
expand into these areas.

DISCUSSION...Latest radar loop shows a band of storms continuing to
move east across eastern Arkansas, through an axis of 3000 J/kg
mixed-layer CAPE per objective analysis.  While flow aloft remains
relatively weak downstream, degree of instability and the organizing
presence of outflow at the leading edge of the convective cold pool
suggests at least some risk for locally damaging winds east of the
river.  As such, ww 352 will be locally expanded eastward to cover
potential wind risk.
