Not the park, but central LI in some January's with "poor starts" (note that the 1.3" on 1/31 /21 was the start of a 17" snowfall):: J A N J A N J A N J A N Day 2005 2015 2016 2021 1 0.0 0.0 0.0 T 2 0.0 0.0 0.0 0.0 3 0.0 T 0.0 T 4 0.0 0.0 T T 5 0.2 0.0 T 0.0 6 0.1 0.5 0.0 0.0 7 0.0 T 0.0 0.0 8 T 0.0 0.0 0.0 9 0.0 1.7 0.0 0.0 10 0.0 0.0 0.0 0.0 11 0.2 0.0 0.0 0.0 12 0.0 0.0 T 0.0 13 0.0 0.0 0.0 0.0 14 T T T 0.0 15 0.0 0.0 0.0 0.0 16 0.1 0.0 0.0 0.0 17 2.5 0.0 0.9 0.0 18 0.0 0.0 T 0.0 19 3.1 0.0 0.0 0.0 20 0.1 0.0 0.0 0.2 21 0.0 T 0.0 0.0 22 11.4 T T 0.0 23 3.0 0.0 17.0 0.0 24 T 4.0 0.5 0.0 25 0.0 0.0 0.0 0.0 26 1.0 5.0 0.0 0.3 27 0.1 10.0 0.0 T 28 0.0 T T 0.0 29 0.0 0.0 0.0 0.0 30 0.1 0.8 0.0 0.0 31 0.0 0.0 0.0 1.3 Total thru 1/15 0.5 2.2 0.0 0.0 Total for January 21.9 22.0 18.4 1.8 Max Daily 11.4 10.0 17.0 1.3 Footnote: Snowfall here this month through January 12 is 1.1" (ahead of 2005, 2016, and 2021). I think that the big snowstorms spawned those months were all Miller B's, even 2016.

I'm not sure how long it lasts, but it is more typically towards the end of the month. I've always felt it is one of those things that you can subjectively fit into any January... there's always going to be a few days warmer than all of the others.

This reads more like a "normal up", although there were those 50⁰ maxes 1/8-10. IMBY:

Do you feel better now?

Nice snow squall here

A trained spotter ought to know the difference.

Mmmmm, perdy. Lock it in.

Is this how you met: "Read any good skew-T's lately"?

Are you a bot?

I kind of get the rationale for -3C being a threshold proxy for enduring winter snow cover, but what is behind the 64.4 for tropical? (apologies that we are mixing °C and °F)

I agree. But it's not colder.

I'm not sure everyone would agree. By the way, the two charts you posted show NYC's warmest period and one of Raleigh's coldest. It still says something about how NYC has warmed, but is a stretch for the subtropical argument.

Those places are not warmer (except for the subway grate scenario)

No denying the recent winter warmth in the park, but I'm not sure where you will find a more urban environment. Maybe on top of a subway vent.
