Here in Fl we can see DA in the minus readings and baro above 30.30 in the late winter AMS early spring at Orlando and Gainesville. It?s rare though. Typically that type air is 2-3 tenths faster than usual air.

We do have Bristol tbf, air blows there, especially in June when they host the national.
