Yeah it'll be interesting to see where the inverted trough sets up and how far east the sub freezing temps can get for you guys. If I were within 1 or 2 layers of counties from the freezing line on the models I'd certainly keep a watchQuestion- if the models have a hard time with swallow layers of cold air near the surface, then isn't reasonable to figure in some sort of margin of error as it relates to the east progression shown on the model runs?
