I just didn’t remember it ever feeling real cold but I guess you get that when the bookend month’s of say Nov/Dec and Mar have higher departures. February, the coldest month had the warmest departure. Honestly that’s probably a perfect way to run a winter...coldest at the bookends and then not as big of departures during climo coldest time.
Though I will say, January up here had to be the most enjoyable way to run a -3.5 departure. Looking at dailies it does look like it was overnight mins that were cold and the daytime temps weren’t bad when folks were out and about.
A day where it’s -17F in the morning but 15-20F in the afternoon, is solidly below normal mean but that afternoon in January in NVT is pretty comfortable. We had 15 mornings below 0F in January but none of that was like those days of -15F that only rise to -5F in the afternoon....just a lot of cold mornings and more tolerable afternoons.
There’s probably some decent feedback with consistent, deep snow cover starting early in November that likely fed back into colder mins...sort of maximizing the air masses we did have as far as cold goes in a radiating climate spot like the valleys here east of the Spine.
