and then you have to consider the strong LP along the mid- atlantic coast shown on the 12Z Canadian - lets see if the Canadian shows that at 0Z

Greenland blocking is usually warm East/cold West in March. I thought it was some time in late April or May that it flips.

That's incorrect. The opposite is true. Winter/early spring is cold; it flips later spring/summer. Here are 500 mb anomalies and temperature anomalies for March Greenland blocks:

Here are mean temperatures for NYC (1980-2025):

March 1-15: NAO -0.50 or below: 39.3°; NAO +0.50 or above: 41.5°

March 16-31: NAO -0.50 or below: 43.3°; NAO +0.50 or above: 46.4°

Finally, what does AI say about the posted map under discussion?

Canadian would be the best solution for most… was very close to all snow for nyc Long Island as well… front end to rain

Record warm SST anomalies in the North Pacific, including year after year of marine heatwaves, continue to push a fast northern stream which is why it's been impossible to get a traditional, benchmark KU storm aside from 2021 and 2022 (for part of our forum). Until we see some sort of decline in North Pacific SSTs, this problem will continue. 

Or a marine heatwave somewhere else counteracts it. It’ll be interesting next winter if we go into a Nino, hopefully the western Pacific warmth can shift east and nudge the forcing east of the Dateline.

The persistent and often severely cold pattern is poised to break. However, exceptional warmth appears unlikely through at least mid-February, even as milder readings return. After mid-month, highs could begin to reach the lower 40s.

Tomorrow will see the temperature reach or exceed freezing. Wednesday will be even milder with the temperature topping out in the upper 30s. A cold front will likely cross the region, possibly touching off a few snow flurries or showers. It will turn somewhat cooler into the weekend.

The ENSO Region 1+2 anomaly was +0.3°C and the Region 3.4 anomaly was -0.5°C for the week centered around February 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.25°C and the ENSO Region 3.4 anomaly has averaged -0.52°C. La Niña conditions will likely continue into at least late winter.

The SOI was +4.66 today. 

The preliminary Arctic Oscillation (AO) was -2.895 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 90% probability that New York City will have a cooler than normal February (1991-2020 normal). February will likely finish with a mean temperature near 31.2° (4.7° below normal). 

Supplemental Information: The projected mean would be 4.1° below the 1981-2010 normal monthly value. 

Overall, Winter 2025-2026 is on track for a seasonal mean temperature of 31.9°. That would be the lowest winter mean temperature since Winter 2014-2015 when the mean temperature was 31.7°. Winter 2025-2026 would only become the fourth winter of the 21st century with a mean temperature of 32.0° or below.

Just saw on the memories in my Iphone, today in 2017 was a blizzard for many of us. Was in the 60s the day before, 2/8/17, with a winter storm watch for 8-12" of snow for the next day. I remember how many people in my inner circle couldn't believe it would snow the next day. Precip started out as rain around 40 degrees around 4 am, and then temps crashed and it was snowing by 5:30 or so. Very heavy snow all morning, 9-12" here in NYC, and a blizzard just to the east of us. Great storm, followed by deep cold. 

must have missed nj altogether.. i remember a few slushy inches around that time....perhaps that was the one?

The snow was blinding at times.

As I was driving past Little Neck Bay today I was amazed to see the whole thing frozen. I havent seen that in years.

And then I was floored to see it frozen thru the Throgs Neck Bridge. I have never seen that!

Over the past few weeks I have been playing whack a mole with frozen pipes. I dont want warmth yet but normal 30s day 20s night will feel…good

I remember that one, was a fun event in Nassau County. I think I had 10” or so. Was one of those that blew up for NYC and NE into New England.

You havent been paying attention since 2015 then hahaha. All kidding aside, my gut (and a long range forecast) tells me the bulk of winter is behind us

I mean it’s Feb 10th now. Temp averages start going up pretty substantially from here and the sun is noticeably getting stronger. It’s the equivalent of August 10th in the summer-can still be hot but the worst is in the past.

young men are failing out of school like crazy. i know lots of them. hence the efforts to stem the flow. my friend's daughter is in med school and can practically count the males on one hand......seeing it across the board in many professions. my son finished his masters and he was the only man in his whole cohort, in a science degree.

Advanced degrees are different. A bachelor’s it is incredibly difficult to fail out of if you keep showing up. Masters and PhDs and MDs do have a lot not mae it for various reasons. But the sad thing is we are seeing very few males in STEM. I have very few males in many of my classes now.

Ahh no. Sun is no where near August 10th. We still have more darkness than daylight. We are still in November sun. 6 weeks to the equinox. Sorry to burst your bubble.

Probably before many here were born, but today is 57-year anniversary of The Lindsay Storm.

In Queens at the time and very difficult to measure. 17.7" was my best attempt.  No pictures, but I remember tunneling into back yard where the snow was scoured out in the middle to some bare ground while surrounded by drifts reaching to the second floor.

You'll be relieved to learn that one person (at least) understood the point you were making -- the most extreme portion of winter is now past, like on August 10th the most extreme part of summer is done. But nearly similar records can still be hit. 

(he wasn't trying to say the sun angle on Feb 10th = sun abgle on Aug 10th).

Enjoy the cold while it last because it will pretty much be done when February is over. March will start out warm, with at least one 60+ degree day in the first week of the month.

While it lasts? C’mon... It’s been nippy nearly the whole season since thanksgiving.
