Possible Record Breaking Cold + Snow Sunday 1/25 - Tuesday 1/27

[Prue11]

We better hope for a good thump on Li to reach 10-12”

[WeatherGeek2025]

The cold front is rolling through. You can feel it. It's windy and the temperature dropped like 3° rather than like 10 minutes.

Starting to think the result will be a very sharp gradient of snowfall amounts, something like 4-6" JFK, 6-8" NYC, 8-10" LGA, 10-12" Bronx, 12-14" White Plains and 14-18" lower Hudson valley. Those gradients will then run in a generally w.s.w. direction across NJ into e PA. The axis of heaviest snow still where I thought earlier, Allentown to Catskills to n/c CT to e/c MA. These sharp gradients will also show up on Long Island from south to north shore with a range from 4 to 10 inches, and in s CT, RI and se MA. If the storm begins colder than modelled then possibly these phase changes will hit later in the precip cycle, I would still expect the change-overs in some areas but snowfall totals could then be 2 or 3 inches higher before the phase changes. 

Somebody was asking about lightning during this event, would not be surprised if there was widespread thundersnow mid-day Sunday, about when the coastal low is deepening fastest.

Disagree. I think even JFK gets at least 8”. Maybe LGA gets 10”, but I don’t see JFK at 4 and LGA at 12”. It’s never happened before and doesn’t make sense here either.

Some of the short-term models are showing 2 to 3 in./h rates at times on Sunday. It doesn't take many hours of that to get near double digits.

I don't really consider far southern coastal New Jersey part of the forum. That's more for the mid Atlantic or the least the Philadelphia forum. 

Cape May is almost as far south as DC.

For trivia, the biggest daily snowfall difference between JFK and LGA is 8.5". On February 17, 2003, JFK saw 21.6" while LGA saw 13.1".

I’ve seen enough: 8-12 for Central Park

Corona mesonet site just recorded a 2 degree drop in 5 minutes!

Yep, can definitely start to feel it. We still have some snow on the ground here so I guess this will count as snow on snow. Still a couple inches in my backyard.

Wow, one can say it’s less exciting and still track. They’re not mutually exclusive. I know you’re overly sensitive MJO but maybe relax a bit. 

Have hope

10.2 total sleet and snow will fall there. 8.5 will be the official incorrect total measurement.

Yep, and I think Pivotal maps don’t count sleet as snow, so I could imagine there being up to a couple inches of sleet on top since sleet is a 3:1 liquid ratio. 0.6” of water as sleet would be almost 2”.

Maybe I'm blind, but I thought the 18z Euro was better everywhere.

You could drive from the Texas/Mexico border to north central Vermont right now and be under a WSW the entire way. Wild.

Part of me thinks he’s just bitter that the storm trended to a sleet/ice storm for his area and now he’s rooting on an enormous north trend to spite the rest of I-95 too.

DT is bitter.  He is a jerk and a social misfit. Just about every time the forecast goes against what he's forecasting or his area is not gonna be in the bull's-eye he somehow is sick or his server is down or he's just so damn tired.   How convenient.  It's like clockwork with this guy.  So quick to put everybody else's forecast down when his own forecast usually sucks.  And don't tell me he's a good forecaster because I've been watching him for many years because it's a train wreck with him.  

[Blizzardo]

The leftover snow on my property is already frozen solid again! 

[Blizzardo]

C'mon NAM! I hope this is the time we get NAMd! Because we ain't been NAMd yet! 

And it's usually about this time frame!
