It's a problem when a 75+ degree day in March is talked about like it's "just a nice spring day", but 40 and rain in April is "well below average". I think some have an unrealistic expectation that the weather should be 60+ daily in the spring and that just isn't the case in the northeast. People do want warmer weather which is part of the reason why many move south. I always look at the record lows and see how much colder it could be, that should be put into perspective when people want to talk about how cold it is. It's been said before, people are getting used to the warmer weather. The general public wouldn't bat an eye if April was +3, but they would if it was -3, that's for sure.

Well if you consider the average high right now is probably around 58 or so, depending on where you are of course, asking for some nice days in the low 60's isn't really a stretch.  I mean it's 36 right now at 1pm, and last week it barely hit 40 with full sun.

That was in 2020 leading up to the record May snowfall. April 2002 was only a little warmer than average by modern standards. But the warmth from the 13th to 19th was very impressive.

dry and warm with the clearest blue skies I've ever seen,  quite simply the ideal weather

Looks like it could still be correct with a bit variation across the area:

Screenshot_20250412-131856.thumb.png.6555aa61a9247e5bca235d7cb7b85140.png

 

that 3.20 and that 0.08 (both in Nassau County) are off by a lot lol

With that said, rainfall amounts dropped off a lot east of Nassau County.

We got a little over an inch here.

Do they have a similar product for snowfall?

Snowfall isn't listed as a choice sadly.

Stuck in the low 30's all day here with mist, drizzle and some sleet mixed in at times.  Everything pretty much melted on paved surfaces. Still some depth 1/2" - 3/4" on the colder surfaces.  Was just outside and things a bit slick under foot with temperatures hanging around 33 degrees currently.  Might be some black ice issues overnight if temperature drops to or just below freezing.

Clouds will break tomorrow with the temperature approaching but falling just short of seasonable levels. Monday and Tuesday will be somewhat awrmer than normal before another surge of cooler air moves into the region by the middle of next week. Milder air will likely return to end the week.

The ENSO Region 1+2 anomaly was +1.3°C and the Region 3.4 anomaly was -0.1°C for the week centered around April 2. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.23°C and the ENSO Region 3.4 anomaly has averaged +0.17°C. Neutral ENSO conditions will likely continue through at least late spring.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was +17.30 today.

The preliminary Arctic Oscillation (AO) was +2.421 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 68% probability that New York City will have a cooler than normal April (1991-2020 normal). April will likely finish with a mean temperature near 52.5° (1.2° below normal).

Don was LGA the only one of the city stations/local airports to record a Trace of snowfall today?

I'm not saying that asking for average temps is a stretch but everyday isn't average, especially with how springs (particularly April) are around here it's tough to expect sustained nice weather. I'm just saying if it was a week of 75+, not many would complain.

I agree, which is why I dislike those "teases" where we hit 80 for a day during the 3rd week of March.  Inevitably it will turn ugly again.

Completely normal for mid March to late April.  That's why you dont plant tomatoes here  till May 15th here. 

I guess it depends on where you're at, around here we've not had a freeze later than April 20th in my lifetime.

Or one earlier than October 15th.

Yes. None of the other local airports recorded any snow.

Apologies in advance if this was already mentioned (took a quick look at the last few pages and didn't see it referenced), but is this not the 2nd latest recorded snowfall, if not the latest, in the last 50 years there?

The most surprising thing about this storm is how little snow has melted in 24 hours considering it's the middle of April. I ended up with 2 1/2 to 3 inches of snow on various parts of my property I ended the day yesterday With about the same snow depth. I wake up this morning to about 2 inches of snow on the ground. 
 

What happened to that sun angle that some people start to talk about in the middle of February? I would think the middle of April it really would've done a job yesterday even with a cloud cover. Same sun angle in the middle of April as late August.

This wasn’t that big of a deal. Since LGA had accumulating snow and not just a T a few days later back in 2014. Then a T on 5-9-20. Maybe if the low temperatures were really cold like the maxes were yesterday they could have had a light accumulation.

The big deal was this kind of weird late season cold/snowfall isn't supposed to be happening anymore, so this is likely a one in 20 year event we just saw.

It's very rare to even get a T of snow after April 10th.
