I've touched on this subject quite a bit the last two years, but now that we're down to the last three weeks I thought it would be a good time to review where NYC, Central Park specifically, stands in the quest for a 30 inch snowfall average when the new 30 year averages are calculated next month. For those not aware how it works the 30 year snowfall averages will be calculated for the period from January 1991 through December 2020. In short this will mean say goodbye to the 1980's from the averages, which hold the record as the least snowiest decade recorded. Assuming NOAA calculates the averages for each month by rounding up or down to the nearest tenth of an inch, the months who have their 30 years completed look as follows: October..........0.1 November.....0.5 December.....4.9 (29 year avg) final number to be determined January.........8.7 February......10.1 March............5.0 April..............0.4 May..................T The 30 year average calculated now would be 29.7 inches. To get December to a 5.2 average, or in this case 5.15 which should round up to 5.2, Central Park will need to record 11.3 inches of snow this December, which is what will be needed to get the 30 year average to 30.0 inches. Currently the December 1991 -2020 period averages 4.773 inches which would round to 4.8 and would make the 30 year average 29.6 inches if no snow falls this December. Here's to hoping that if Wednesday is indeed a surprise heavy snowfall for the city, the Conservancy? doesn't measure 11.2 inches and leave us hanging for the rest of the month.

You're 30 years are off slightly from mine Uncle. February will be 10.1 as they don't add the 3 decade averages and divide by 3, but they add each of the 30 years and divide by 30. February average is 10.147 when done my way which I assume they will round down to 10.1. January is the same, it comes out as 8.740 my way, which again I assume will be rounded down to 8.7 Either way we're close. I'm hoping it happens, if so it will be the first 30 year average above 30 inches in NYC since the 1891-1920 period.

Oh God I hope not

Sun angle coming into play now. I had to say it just so it's been said. Can we agree that we will all be pleasantly surprised if those words are not uttered again in this forum. I accumulated snow on May 9th last year in the middle of the afternoon. I'm pretty sure the sun was up that afternoon, although with all those clouds and snow impeding visibility who can really be certain.

0.9 inches on the board here. 31.8° and down to light snow.

32.0° on the nose and yes Rob the flakes are the largest of the season, as the biggest snowfall of the season continues.This may surpass the storm of May 9th, or even the upcoming Met winter, if the October snows lead to a crappy winter theme continues. Officially 0.7 inches on the board.

Down to 32.4° with moderate steady snow. Sticking to trees and grassy areas now and looking winter like.

Down to 32.4° with moderate steady snow. Sticking to trees and grassy areas now and looking winter like, which is always nice. So most of us will end up only having to go from May 10 to October 29th without seeing measurable snow. Amazing when you consider what went on during most of last Winter. We shouldn't even refer to it as winter, it was just an extended Fall. Let's hope for once another accumulating October snow doesn't lead to a crappy Winter. These always leave me feeling uneasy because I've seen this script end in disaster too many times.

32.7° and Snowing moderately. Temps have dropped 4 degrees since 5:30 Beginning to stick to deck and some grassy areas.

32.9° and Snowing moderately and I'm only 45 miles north of NYC. Beginning to stick to deck and some grassy areas.

47 this morning. An inch of Snow and snow squalls second week in May and a hard freeze in mid May. I’ll sign for this spring every year. Maybe without the Pandemic, riots, and social unrest. Maybe next year I spend spring in Chaz?

Not sure if anyone pointed this out yet but the May 9 snow in NYC was the seventh month in a row dating back to last November that NYC saw at least a trace of snow during the month. This is the first time in the 150 years that records have been kept that this has occurred. Why doesn’t it surprise me that one of the all time worst snowfall seasons in recorded history would set a snowfall record, dubious as it is. And with that said I’ll see you all in October.

Bottomed out at 31.8° this morning, I think we make one more run at freezing tonight in the N&W suburbs, and maybe SE LI. The average last freeze in this area (HV) is May 5 so it is a late freeze this year.

I agree. I hit 31.8° this morning, we may challenge that again tonight, but I think the nights of freezing are done for this spring after that.

After the 0.8 inches on May 9 I’m now at 22.9 for the season. I’m contemplating adding a couple of tenths for the squalls that blew through Saturday afternoon. I Easily added 0.2 to 0.4 during those, but it quickly melted once they ended. The NWS needs to set out clearer guidelines for these May Snowfall events. Either way still my worst season in the ten years I’ve been keeping complete records. Hopefully I’ll be adding to these totals before the season closes June 30. Maybe a flag day surprise?

Heavy squall for 20 minutes just starting to wind down. Accumulations began on grass and cold surfaces again. temp dropped from 41 to 35 during the squall. If anyone talks about sun angle in late February next year and how the snow won't accumulate during the day, I may have to seek them out just to slap some sense into them, while holding photos from today.

Best May in 43 years.

31.1° and an inch of fresh snow still on the ground. Looks amazing against the pink flowering trees. Bottomed out at 28.3° this morning. Was wondering if I'd ever see accumulating snow in May again, especially with how warm the planet is becoming. It's been a 43 year wait to see it again but was worth it for the novelty of it. It doesn't make up for the worst winter ever, but it's a nice attempt at an apology from mother nature. This is why you can't plant around here until the middle of May at the earliest.

Down to 36 in city, with the first snow in May since 1977. I know it’s highly unlikely they reach 32 tonight but curious what the latest freeze is in the city?

Snow lightning up. 32 degrees and 0.5 inches on the ground. Second best May snow of my lifetime.

0.3 inches and still snowing. This won’t approach the 3 inches we got on May 9 1977 but still an oddity worth staying up for.

Down to 33.8°, snowing moderately and now sticking to grass and tress.

34.2° and moderate snow falling. It's been exactly 43 years to the day that I could make that statement on May 9th. Of course that storm produced 6-10 inches of snow in parts of SE NY SNE and Central NY and NE. Slide mountain NY received 27 inches which was the jackpot in that memorable storm. Now lets see if this one can produce any accumulation, an inch or two would be pretty cool.

I haven’t seen accumulating snow in May since May 9-10 1977 event which was very interesting. After one of the lousiest winters ever I feel I’m owed this. I don’t include others because I’m not quite sure if everyone is in on May snow. Personally I’d welcome snow in June just for the record books.
