I’ll agree… the real cold days have been about normal. Normal is pretty damn cold in January and February. But a -20F summit windchill is like what one might expect in Jan/Feb at 3k+ feet, a couple counties within the Canadian border.
We averaged low single digits for a long time, even now it needs to hit 6F every night to have a shot at below normal. Its only hit 6F once in 17 days.
14 of 17 days have had mins of 12F or more when the average has been 2-6F.
