Last year I took the family up to deep creek/swanton for MLK weekend. We had 6-10” from the storm that came through which was too warm for the folks further east. Then the upslope turned on and we had whiteouts on and off. Finished at 21-22” for the weekend
5” OTG at the mason Dixon line just north of emmittsburg. Can confirm cc line dropped back S/SE and snow started getting very heavy at that point. 29 degrees.
