We've seen severe storms across the mountains this afternoon, and nickel sized hail was reported in Buncombe county. We'll have strong storms in the mountains through 5pm, then they will slowly drift into the Upstate and northeast GA.
We've warmed up a LOT out there, and humidity levels are high. So, storms will have plenty of energy/fuel to access. The good news is that there isn't much shear in the atmosphere, so we shouldn't be looking at long-lived, organized storms, plus the tornado threat will be pretty low. Damaging wind and hail will be the main threats from now through 8pm in the mountains, and 4-10pm in the Upstate/northeast GA.
Rain will continue overnight once the storm threat diminishes, therefore we could find some localized flooding tomorrow. Mountains stand the best chance of getting up to 2 inches of rain, while 1-1.5 inches will probably be common area-wide. Some of the heaviest rain will fall for the Wednesday morning commute.
Rain should end by late Wednesday afternoon, and cooler temps will prevail. Highs will only reach the 50s for the mountains and 60s in the Upstate.
