I've noticed over the past couple years some of the HREF members tend to be a bit too cold at 2m and can over-do the low level drain down the valleys here in CT.
But it is definitely interesting seeing the 12z HREF mean solidly below freezing in Hartford at 12z while HRRR/3km NAM (which are both HREF members) much slower. Shows you how frigid those other members are.
I'm hoping by later today we have a better sense of where that weak wave forms to our southwest and where the front sets up.
