Can It Finally Be...An I-95 Snowstorm?

Hello this is Junior Meteorologist Kyle Elliott with a weather pattern discussion...and there is much to talk about today, so I'm going to get right to business. First, an arctic airmass will plague the entire eastern half of the country through tomorrow and Sunday before moderating into the 20s and possibly even lower 30s for most places south of NY State and north of central and southern Virginia where 40s could be found by Tuesday or Wednesday. Before that moderation happens, though, could it be...?...an I-95 snowstorm? Well, the GFS 12z run that has just run out no sooner than a few minutes ago says so, while the NAM model that ran out about an hour go thinks not. According to the NAM, the area of the I-95 corridor from D.C. to Philadelphia into southern Pennsylvania and northern Virginia once again gets ripped off like normal, while places north of that in New England get the snowstorm. The GFS, on the other hand, finally has the entire corridor from northern Virginia to D.C. to southern PA to Philadelphia to central NJ finally receiving a solid 3-5 inch snowstorm late Sunday night into Monday afternoon, while New York receives about 5-7 inches on Monday. Boston to Maine are still the big winners according to the GFS too as they receive on the order of 8-14 inches, but I think snow-starved folks from D.C. to Philly would take 5 inches of snow anyday at this point. Personally, I do not want to go out and make an actually written forecast yet as there is far too much model digression on this storm at this point, but I will say that I am leaning towards the GFS model only because there is a negatively tilted trough on the East Coast during that time frame along with a lot of southern moisture being pulled up into the Mid-Atlantic states. I have a bad feeling that this storm actually tracks further WEST than the GFS has it even though the NAM has it still going out to see, but we will see about that later tonight and tomorrow. If the storm were to track about 100 miles further west, the I-95 corridor would probably see a nasty mix of snow, sleet, and freezing rain while the axis of heaviest snow would run from Winchester, VA, to Hagerstown, MD, to Harrisburg, PA, to Poughkeepsie, NY, to Worcester, MA. That is my best call at this point, but like I said earlier, I am only about 25% confident in that forecast at this point, and I will make a first thoughts snowfall map later this afternoon which would correspond with my above thoughts. So that's about all I have for now as there is far too much model disagreement to write more, so hope ya'll have a great rest of your afternoon and I'll talk to ya'll later!
