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.

Koppen may be useful for some sort of macro-climate modeling, but not for much else. I think the "subtropical" nomenclature is off. As a speaker of English it does nothing for me. I'll take the USDA hardiness zones, unless they've been updated to make some political point.

Could be. I'll check that or when I get a moment. I think there were some negative mid-teens in places here around 1984 and 2009 as well, but usually my memory of radiational cooling fades as fast as the temperature rises when the wind picks up.

That looks like a MA blockbuster with snow to mix and dry slot NYC to BOS. I guess I'm still a little disappointed about 1993

The Jan 1961 period is when BNL recorded its lowest ever at -23⁰ F (-31C). Surprised that KFOK only got down to -1 during that period.

Today's record low for Islip is -4 from 1968.

Corresponds with the persistent cloud cover over the east end. https://weather.cod.edu/satrad/?parms=local-Rhode_Island-02-48-1-100-1&checked=map&colorbar=undefined

Attention complaint department: What's with the Koppen Climate classifications? Calling NYC "subtropical" seems like poor nomenclature. What is the utility of having NYC in the same climate classification (humid subtropical climate) as Orlando? If that's true, why are there snowbirds?

Nooo...NYC got 4"+ in December. Doesn't that mean the rest of this winter is a burial?
