Better get used to it. Longish winter warm stretches interspersed with sudden polar vortex snaps will become the new normal out east.
Out west it’s a pretty normal winter so far (fall was much drier that usual though), right now we’re digging out from a couple winter storms. Finally the local ski hills have a good snow pack. Next week it’s back to rain at least at sea level. Spring end of Feb is around the corner.
