Winter Storm Update...0z NAM Is...WOW!

Hello this is Junior Meteorologist Kyle Elliott with our 10 P.M. winter storm update...and there is only one word that I can use to describe the 0z run of the NAM model: WOW! It went from having a weaker storm far offshore to now having heavy precipitation over our area and a much stronger low closer to shore. So what does this mean for us? Well it means that the rain/snow line is now farther north: anywhere from central and southern York County to Reading, PA...to Allentown, PA...to Poughkeepsie, NY...to just south of Boston, MA. On the same token, that would mean a 4-8 inch total storm accumulation for places like Hagerstown, MD...to 10 miles either side of Harrisburg, PA...to just north of Reading, PA...to Easton, PA...to Poughkeepsie, NY...to Boston, MA. North of that line, a general 2-6 inch accumulation would fall, and south of that line, where rain mixes with snow, a general 2-5 inch accumulation would fall. Bascially the NAM now shows a stronger, warmer, and somewhat "closer-to-the-coast storm." So I will have to wait for the 0z run of the GFS model before I draw my evening conclusions, but I have noticed that the circulation is already beginning to form south of New Orleans, Louisiana, and the storm does appear to end up moving farther north and slightly farther west than thought earlier this afternoon. So that's where things stand for now, so I will update again later when the 0z run of the GFS model comes in. This has been Junior Meteorologist (Storm Tracker) Kyle Elliott with a special update for the AKStormtracker Forecasting Center, in High Anticipation Mode!

Note: If the 0z run of the GFS continues to show at least a moderate storm, I will be going into Storm Alert Mode which I will continue in through Monday morning.
