I'm thinking the afternoon/evening threat for northeast AL/northern GA might be a little higher than the forecast thinking earlier today. The 12z NAM3k showed a very strong wedge extending all the way into central AL that didn't budge at all, while the HRRR has been more aggressive with advancing the warm front northward. The HRRR seems to have a better handle on temperature trends , as heating has been pretty good so far even under the clouds (as I type this it's almost 10 degrees warmer at KATL than the NAM3k had) and a substantial region of clearing is rapidly advancing into GA which will almost certainly destabilize the airmass.

Both models have consistently indicated development of storms over AL and west GA late this afternoon, likely reaching the Atlanta metro by the 8 PM EDT timeframe. Difference is that we'll probably have more instability to work with than we maybe thought this morning.

Rotation appears to be weak and diffused on the Alabama Conecuh Co tornado warning per my GRL3. More of a hail threat atm.

Got a couple of SVR storms sneaking up on North Alabama. Was beautiful for a large portion of the day. Glad to see Dega dodge the weather so far.

A surprise in Guntersville, AL we had been taken out of the slight risk so we weren’t expecting this. We were outside doing yard work when they put us back in the slight risk and added the severe thunderstorm watch. Hopefully the truck doesn’t have too much damage.

Posted my chase account on Stormtrack from what was an incredible show near Vernon and Lockett TX yesterday featuring multiple photogenic tornadoes.

Brittany and I have lived in the Athens area for fifteen years. We have never seen it get so dark so early before sunset in the middle of Athens. That's what she described to me while she was out this afternoon.
