Valid 100233Z - 100430Z The severe weather threat for Severe Thunderstorm Watch 620 continues. SUMMARY...Scattered supercells will spread southeast across eastern AL into western GA over the next few hours. Hail and wind remain likely with the strongest storms. Some consideration will be given to extend the watch a bit south and east. DISCUSSION...Weak short-wave trough currently extends from eastern TN into eastern AL. This feature is low amplitude but appears to be aiding scattered supercells currently located along a corridor from Shelby County AL to Harris County GA. Seasonally strong 500mb flow extends across this region with 35-50kt west-northwest flow, which is more than adequate for sustaining organized updrafts. While much of northeast AL/northern GA have experienced significant boundary-layer stabilization, steep lapse rates and 2000-3000 J/kg MLCAPE persist across the undisturbed warm sector along a corridor from northern MS-central AL-southern GA. This activity should continue to propagate southeast with an attendant threat for hail/wind. ...Darrow.. 08/10/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!4w8GtEr_DT4aA8ZJK6tGYkT6YV1iIekLHHjyaQ-dFatl5Dd2UELPB59W1NiWREHZGOpAtN6wK= Dk4sAuHk5u81N_A3t4$ for graphic product...
