It's still pretty breezy here, so temp's dropping at a snail's pace... only 8F currently. The HRRR holds that winds will go dead, or close to it, by 2 am. With sunrise before 7 now, that wouldn't leave a ton of wiggle room in the quest for <0F.
It's amazing how some years I need everything to go right for a subzero low, and in others they're a dime a dozen. I think I was pushing 20 nights below zero in 14-15.
