kmsp - Wow, what a storm!! While the northeastern United States has had their fair share of snow storms over the last several years, I think this one may take the cake. More than 40 inches of the white powder fell in parts of the Mid Atlantic as tens of millions were affected by this one. This was the single largest snow storm in history in several areas including parts of New York, Maryland, DC, and Virginia. More than 30 inches of snow fell at New York’s JFK airport, the largest single storm snow total in city history. Baltimore had a staggering 29 inches, along with the west side of DC. No records set in Philadelphia, but the city still saw just shy of 2 feet of the flakeage.
Records aside, what made this storm different then all the other Snowmageddons? It was the sheer size and location of all the snow that really made the difference. This storm dumped snow on at least parts of 24 states with it dropping the most on the most densely populated corridor of the country with tens of millions digging out of over a foot of snow. The only thing that may have made this storm even more epic is if it had continued northeast instead of pulling out to sea. That would have given Boston similar totals to New York, instead of the 6 or so inches that they received. Check out the snow totals from the eastern part of the country courtesy of weatherbell.
What also made this storm different than many of the others in recent years is just the scope of how quickly things can change over short distances. Let me show you. The following is from the National Weather Service in Binghamton New York which covers parts of Pennsylvania.
This shows that there was nearly a 30” difference in total accumulation in less than 50 miles in northern Pennsylvania. To do the math, that’s two thirds of an inch every mile. That is absolutely INSANE! In a lot of the other Nor’easters, there is a pretty gradual drop in snow totals from the areas hardest hit. This storm had about one of the sharpest snow accumulation cutoffs I’ve ever seen.
