I'm around 38-38.5" now depedning what my final is today, so your in the ball park. MHT should be in the low 40s after today (35.5" before today). @NHDrySlot says he's over 50" in Bedford. Strong gradient north and west this season.
I think we can still add a little but itll become mroe rate dependent. Those echoes to southwest are the ones to watch as they build ENE. Hrrr/Rap both still enhance those across southern NH for a few hours later this morning.
Soundings for SNH are well below freezing through the column on the hrrr. My guess is the sleet coloring on the maps is showing up from a dry dgz with lower level lift. Could just end up crap flakes vs sleet, but there is a ton of dry air aloft.
