"Correct. The range I put out is six-to-ten inches for New York, followed by some sleet, and that's very much on the conservative side. Which is definitely intentional, because I feel that the potential mixture mixing with sleet at some point during the storm creates a lot of uncertainty. It's unclear to me when that sleet changeover is going to occur. So I'm at six to 10 right now, but getting higher amounts than that is totally not out of the question."
"A little bit about the dynamics of this event: It's definitely not a classic, or one of the historic-looking snowstorms. Typically, our biggest storms come from systems that reform off the coast and form into a strong coastal low. If you remember January 2016 or even what's called the Boxing Day Blizzard on December 26th, 2010, those storms all had a coastal low that really strengthened rapidly off the coast of New Jersey and South Long Island."
An unusually expansive winter storm will affect New York and surrounding areas, likely producing measurable snow and sleet. Forecasted snow totals are conservatively estimated at six to ten inches for New York, with sleet expected to mix in at an uncertain point and the potential for higher amounts. The event lacks the classic coastal low that often produces historic nor'easters, altering typical storm dynamics. Historically, New York's largest snowstorms form when a coastal low strengthens rapidly off New Jersey and South Long Island; being positioned left of a coastal low tends to reduce those intensifying dynamics.
