The odd part is it could have been one of the earliest freezes on record and instead will probably be one of the latest....clearly not a good indicator on what the winter will be like...

That was a really cold airmass here...it was in the 20's and I believe the teens in some interior locations. The snow pack was a big factor there.

Yeah, that would have been the first October freeze according to Uncle's list since 1988.

From the early part of the record, especially pre-1950 data, UHI has played an important role. However, the trend toward later first freezes and earlier last freezes has continued even in recent years where the UHI contribution has not changed much (the City and its surrounding suburbs have not changed appreciably).

1990s:

Median first freeze: November 17

Mean first freeze: November 19

December first freezes: 1

Median last freeze: April 2

Mean last freeze: March 31

April last freezes: 5

2000s:

Median first freeze: November 19

Mean first freeze: November 23

December first freezes: 3

Median last freeze: March 29

Mean last freeze: March 29

April last freezes: 4

NYC won't hit freezing until after the fropa next week.

Thursday night or Friday night.

I am not too concerned with reaching arbitrary temperatures on any given date, especially since the park has reached 33 twice already and JFK already hit freezing.

As of now it should be Sunday the 11th, where the forecast low is upper 20s. But if not it could be the 15th or later with the next cool down.

If NYC doesn't hit freezing during this upcoming "cold" air outbreak- when is the next date that seems reasonable..

NYC's latest freeze date is 12/22/98, correct? Is it possible that we break that record this year?

1948 had its first 32 temperature on 12/11...I know its a local thing because most of us have seen 32 degrees or below a few mornings...1948 ended up with over 20" of snow in December with a major storm on the 19th...
