Just like back in 1895 and 1896 (I kid but you know what I mean lol).

Even as New York City sweltered in 97-degree heat on September 23, 1895, it was on the verge of a dramatic plunge in temperatures. The mercury still reached 90° on September 26, but a sharp cooldown followed. Just two days later, the high struggled to reach 68°, and by September 30, temperatures had dropped further, with a high of 60° and a low of 47°.

The chill deepened as October began, with a low of 44° on the 1st, and the entire first week remained unseasonably cool. A reinforcing shot of cold air arrived on October 9, delivering a low of 38° and a daytime high of just 47°, followed by a low of 37° on October 10. The rest of the month continued a mainly cool pattern, with five more mornings dipping into the 30s, marking October 1895 as a notably chilly chapter in the city's weather history.

With a monthly mean temperature of 52.4°, October 1895 was tied with October 1887 as the seventh coolest October on record. The last October that was at least as cool as October 1895 was October 1925.

That really sounds like the kind of weather I would have loved, higher highs and lower lows lol.

I know March 1896 was the first time we had 30 inches of snow in one month too.

There was a big blizzard in one of those years in January with temperatures near 0 too.

 

Question, how can you have a blizzard with temperatures near 0? Wouldn't the air have to be coming off the ocean? What's the coldest temperature we have ever had in 10 inches or more of snow (high low split during snowfall) Don?

Probably not. I am fairly sure that most or all of the NYC region have already seen their last 90s. 

In fact, there has been a big change in the ECMWF weeklies for the week of September 29-October 6 with the new run that just came out.

9/22 Run:

9/23 Run:

Beyond that, all the weeks are warmer than the were on the preceding run. 

Yeah, looks like all the real cold is limited to Siberia.
