Supposedly the East River froze over and you could walk on it between Manhattan and the Bronx. That’s insane for March. Parts of New York State had 50" + of snow. This is my favorite blizzard and i have a book about it.
The 1888 blizzard had arctic temperatures. NYC was down to 6F at one point. The city started out as rain. Transitioning to freezing rain and then snow.
If I recall correctly the 1888 snowstorm did a loop south of Eastern Long Island.
That track makes sense with 21" of snow in NYC and temperatures in the single digits and a rain/snow mix in Boston and 10".
