12/13 was a backend winter. We had the big Feb Blizzard here which delivered our yearly average in one day and then another monster in March--before Feb I think we had a few inches on the year
I go to Breckenridge CO for a week every Feb-they have snow OTG from Nov-May and it almost never rains in that period. No sleet/freezing rain. It would get old after awhile.
gets to that pressure later now--- only 995-1000 MB until it gets into the lower lakes...so snow amounts are greatly reduced to the west in areas such as WI and Chicago...
you would need precip to be falling to get a true flash freeze-once the rain ends, dry air will pour in as temps drop-the wind and dry air will take care of most paved surfaces outside of puddles/standing water anywhere.
