This is the type of storm that will have some unexpected surprises - now casting time..........I also wouldn't be surprised if there is an unexpected large dry slot that develops because of a sloppy transfer of the storm to the coast
I am not talking outlier regarding snowfall amounts - I am talking outlier regarding sleet/freezing rain amounts rather have dry slot then sleet or freezing rain
NAM is a warning to stay up later Sunday night and remove the accumulated snow from your driveway and sidewalks before the sleetfest and or freezing rain starts.
I think some folks are still over reacting to that mix line because of what happened December 26 with the unexpected speed of the warm layer arriving earlier than expected....
I would count on more adjustments probably south still too early to be sure about anything though IMO. I think the GFS has the best handle on this now and it has been consistent for days now.
