The severe weather threat for Severe Thunderstorm Watch 110
SUMMARY...Sporadic wind damage will remain possible with a line of thunderstorms moving across central Georgia. A gradual weakening
trend is expected as this line moves eastward after 10 PM EDT.
DISCUSSION...The line of clustered supercells has consolidated into
a squall line as it moves across western GA. Although the hail
threat has greatly diminished with these storms, sporadic wind
damage reports have been noted into the Atlanta metro, including a
76 mph report from ATL. Wind damage will remain possible with this
line in the near term thanks to strong 50 knot flow within the
lowest 2 km (per KFFC VWP obs). However, the 00 UTC FFC sounding
shows limited instability, and the onset of diurnal cooling along
with residual cold pool air across central GA are further limiting
factors for this line as it continues east. Recent IR imagery shows
warming cloud tops, suggesting that gradual weakening is already
underway. This trend will likely continue through 10 PM EDT, and
Watch 110 will likely be allowed to expire.
