Low of -20.2 here at WXW2, the coldest temperature I've experienced. Wind chill easily in the -30s. SLK looks to have hit -29, which is a win for the GFS I think. It had temps near -30 in most recent runs. Now we wait to see how warm it gets today. I've never experienced a full 24 hour period below zero.
Low of 3.2 at WXW1 (East Hartford, CT), coldest of the season so far.
Definitely diamond dust in the air this morning @dendrite
