...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast tonight.
...01z Update...
Westerly flow is deepening/strengthening across the Southeast early
this evening as northern/southern-streams begin to phase later
tonight, in response to the maturing upper trough. Scattered
thunderstorms continue along the frontal zone from coastal MS into
southern GA, but have struggled to attain appreciable intensity.
While deep-layer flow is more than adequate for sustaining robust
updrafts, current trends suggest the primary risk with this activity
will be sub-severe wind gusts and maybe some small hail. As a
result, severe probabilities will be lowered for the rest of the
period.
