The problem in Va with the arctic air is that when it moves out in March the warm humid air will move in right away. We will go from heating to A/C in one day. Happened last year, I turned the heat off and the A/C was running the next day. It will oscillate like that and spring will be truncated.
Going straight from cold to a major influx of warm, humid Gulf air is a recipe for some rough spring storms, imho.
