No. There is no record where NYC saw measurable snowfall with a low of 40 or above.

Full hourly information isn't available, but from the data that is available, it appears that that around 0.12" fell when the temperature was 39 and the wet bulb temperature was 38. That was April 1875. Snowfall amounts were: April 7: 0.5" April 13-14: 10.0" (April 13: 8.7"; April 14: 1.3" April 25: 3.0" Total Snowfall: 13.5"

The map is wrong for Brooklyn. No measurable snowfall was reported in the City on the PNS. Moreover, JFK is the closest reporting stating to Brooklyn and the low was 38°. New York City's greatest snowfall accumulation with a low of 38° or above was 0.5" on March 18, 1899. At that time, the City's urban footprint was much smaller than it is today. 393 NOUS41 KOKX 121800 PNSOKX CTZ005>012-NJZ002-004-006-103>108-NYZ067>075-078>081-176>179-130600- Public Information Statement National Weather Service New York NY 200 PM EDT Sat Apr 12 2025 ...SNOWFALL REPORTS...

The first one included occurred during the pre-dawn hours where there was a trace of snow/sleet.

A combination of factors likely contributed including the fading La Niña, abnormal ocean SSTAs (especially a long area of cold SSTAs just north of the Equator).

No. A trace was recorded yesterday. Traces were also recorded on April 23, 2020; May 9, 2020; and April 21, 2021. Had it been measurable, it would have been the second latest in more than 50 years.

Early update on the AI idea for New York City (through April 12th): The monthly mean temperature and monthly maximum temperature are running well below the AI idea. But there are signs that the gaps could close during closing 10 days of the month, if the ECMWF weekly guidance is correct. From April 11th: From April 12th (latest):

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

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).

Depends where one is. If one is at White Plains and northward, there could be a coating. Within 10-20 miles of the City, some sleet might mix in, but there very likely won't be any accumulations. Both the 18z NAM and 18z GFS are very likely overdone.

A cold rain will develop this evening or early tonight and continue into tomorrow. A general 0.50"-1.50" of rain is likely. Temperatures will top out in the lower and middle 40s in New York City area tomorrow. Some sleet pellets are possible outside New York City. Across parts of Central New York State and central New England, wet snow is possible. An appreciable snowfall is possible in higher elevations. Where areas remain above freezing, snowfall amounts will be limited. The temperature could approach seasonable levels on Sunday and then briefly go above normal early next week. However, before the warmth could become established, another surge of cooler air will push into the region by the middle of next 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 +25.81 today. The preliminary Arctic Oscillation (AO) was +2.151 today.

April will likely finish with a mean temperature near 52.5° (1.2° below normal).

The pattern led to a stalled front. Thunderstorms developed and trained along that front for days, producing extreme rainfall in parts of the Tennessee Valley.

Very beautiful. They'll get more tonight.

Northeastern Canada is running colder than normal. Some of that cold air is draining into the Northeast. The AO has less influence now, as wave lengths are shorter.

Tonight will be cloudy, breezy, and cool. Some showers are likely. A few distant northern and western suburbs could even see a little snow or sleet. The week will end on a chilly note. A steady rain will develop tomorrow and continue through Saturday. A general 0.50"-1.50" of rain is likely. Temperatures will top out in the 40s in New York City.

Oceans have been warming from top down. I strongly doubt that his speculation has much merit. That we’re coming off an La Niña suggests that 2025 should be somewhat cooler than 2024 was overall, including SSTs.

It will turn somewhat milder tomorrow with additional showers and thundershowers possible. Highs will likely reach the upper 50s in New York City and middle 60s in Philadelphia.
