The severe weather threat for Severe Thunderstorm Watch 291
SUMMARY...Severe risk continues across eastern portions of WW 291,
and may spread east of the watch with time, where local watch
extension in area may be needed.
DISCUSSION...Latest radar loop shows a bowing cluster of
strong/severe storms which have just moved through the Atlanta metro
area, moving east-southeast at around 50 kt. With the storms
tracking coincident with the northeastern fringe of sufficient
mixed-layer CAPE for vigorous convection, expect storms -- and
associated risk for damaging winds and hail -- to continue over the
next few hours.
Per extrapolation of the bowing segment downstream based on
currently observed motion, storms will begin to exit the current
eastern edge of the watch over the next hour or so. Presuming
storms remain organized/severe as currently anticipated, downstream
expansion of the watch in area may be required.
