I was at Gorham and Wildcat in the third week of March 2019 (when I still lived in MD), and stopped by at Mt Snow on my way back home to MD since it was a powder day. During that trip I completely forgot that spring had officially started, and the snowpack had to be at least 3' deep around Pinkham Notch. Not to mention some bitterly cold days up the mountain.
Unless it's a debacle blowtorch like March 2012, winter will go on for many weeks or months to come up your way.
