Thoughts on January 17-18th storm...
Update as of 330pm...
Well snow is across most of the state with the extreme western areas not seeing to much snow. Heavy bands are still moving north from Maryland with 1-2inch rates coming. Here in harrisburg we have about 2inches of snow with heavy snow falling. Also it is 30degrees and still slightly falling. Roads are covered. Visibility is low. Currently the heaviest snow in PA appears to be around the State College area. Well it looks like my map below needs to have some higher snow totals. I am surprised with all this snow. I think the highest totals will be from Newport to Selingsgrove to Pottsville to Scranton in Pennsylvania. They may recieve all snow with accumulations up to 5inches. It will be interesting to see what mixing occurs late today in Pennsylvania. Stay tuned for more updates. Also looks like another snowstorm is headed our way for Saturday.
More is coming later today, but for now I am going to enjoy the snow while it lasts...

Note the neutral to negative trend in the NAO.
This is my current rain/snow line...
Cumberland, MD to Westminster, MD to Harrisburg, PA to Williamsport, PA to Wilkes-Barre, PA to Monticello, NY
-Anyone northwest of that line should see all snow. But if you are to 30miles on either side of the line then you will be in the mix precipitation zone.
1. large area of sleet and frz rain
2. snow confined to the mountains mainly
3. more rain for already saturated coastal areas
4. variety of precipitation over many areas.
5. fast moving storm, with no artic high to north
