The cold was indeed legit. Here in the Champlain Valley, we were a tad below (horizontal advection) ground blizzard criteria with 6 hours of steady north winds of 16-21mph with gusts between 24-31mph for the duration. There was only two hourly obs of snowfall for the entire storm (some lake-enhanced diamond dust) and the high was 1°F with a low of -8°F. I’m about 18mi south of Burlington. There were some vertical advection components to the storm here with numerous 100m snow devils, likely terrain and lake-enhanced induced since I am just southeast of the lake.
