It's weird looking at these 2 GIFs. the top one has the 6z slamming a LP into TN and 12z its gone. Bottom one as a 6z LP into middle KY and 12z the triangle of KY/TN/VA. It's like the 12z are sniffing out a stronger HP to the north each run and adjusting. If stout walls of cold can stay above it will be interesting to see if the models move to a colder solution or still find ways to punch warm noses into our areas
