The 0.9" was the storm total through 7 pm. Some additional snow has fallen since then, so the final figure might wind up around 1.5"-2.0".

Through 7 pm, Central Park had recorded 0.9" of snow.

This evening. A steady light-to-moderate snow:

I believe the issue is that locations don't show up when one is posting and reading on the phone. I only see them on the desktop.

Whitestone, Queens.

Snow is starting to redevelop across the New York City area.

0.4".

Snow will redevelop and then continue into tonight. By the time the storm departs, New York City and nearby areas will likely see a storm total 2"-4" of snow. Parts of interior southeastern New York State across Connecticut into southeastern New England will likely see 3"-6" on account of higher snow-liquid ratios. Some 8" amounts are possible in southeastern New England. Tomorrow will be brisk with highs in the lower 30s. Arctic air will move into the region on tomorrow night. Tuesday could be the coldest day so far this season with highs struggling to reach the lower 20s and lows in the teens in New York City. Suburban areas could see single-digit lows, especially on Wednesday morning. Wednesday will be another unseasonably cold day. Another shot of cold air could arrive Thursday or Friday, possibly with some snow flurries or snow showers. Temperatures will remain below normal through next week. After January 20th, conditions could become favorable for potentially larger snowfalls, as a generally cold pattern continues. The probability of a PNA+ regime has continued to increase. PNA-related developments would have large implications for snowfall. A persistently positive PNA would have above climatological risk of moderate or significant snowfalls. A mainly negative PNA would favor mainly small snowfalls. The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was -0.8°C for the week centered around January 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.47°C and the ENSO Region 3.4 anomaly has averaged -0.67°C. La Niña conditions will likely continue into at least late winter. The SOI was +22.15 today. The preliminary Arctic Oscillation (AO) was -0.660 today. The PNA was +1.107. That's the highest value since November 1, 2025 when the PNA was +1.698.The last time the PNA was at least this high on January 18th was 2014 when the PNA was +1.263. Based on sensitivity analysis applied to the latest guidance, there is an implied near 85% probability that New York City will have a cooler than normal January (1991-2020 normal). January will likely finish with a mean temperature near 32.0° (-1.7° below normal). Supplemental Information: The projected mean would be 0.6° below the 1981-2010 normal monthly value.

At 1 pm, all the Long Island locations reporting p-type were reporting light snow. Whether the snow is accumulating is a different matter.

The precipitation started as light rain but went over to snow in Central Park with the temperature dropping to freezing. There very likely was an accumulation and that will be reported early this afternoon.

Four photos from this morning:

I think the cold is real and we'll see readings well in the single digits. The figure is around 35%, but the warmer GEFS + timeframe uncertainty likely drive the lower probability.

Overnight, there was a modest uptick in QPF. The general figure for NYC ranges from about 0.35"-0.45". The 12z NBM shows 0.38" with 0.27" from the coastal storm. Warm air advection snows are currently occurring. In parts of the region, readings are just warm enough for some light rain or mixed precipitation. Should precipitation rates increase, the temperature could drop toward 33° in NYC based on current wet bulb and dew point readings and the light rain there could flip to light snow. As the coastal storm approaches offshore, colder air will be pressing into the region. There will likely be several hours of moderate to occasionally heavy snow especially from New York City north and east. New York City will likely wind up with 2"-4" of snow. The NBM currently shows 3.0" for New York City. The colder areas to the north across interior southeastern New York State into Connecticut will likely see an area of 3"-6" snows.

There seems to be a pretty good signal for the 25th. Even the NBE shows > 0.75" QPF at that range.

Different posters.

I'm certainly enjoying the snow and looking forward to the cold. It seems that the AI versions have a lot of merit even as they are still "learning." I've been impressed how far they've come in the past year.

Yes. I agree. We'll see if they ever acknowledge it.

I don't believe 2016-17 is a good analog. I only referenced it, because it had probably the strongest WWB during any La Niña in recent decades. Personally, I didn't think the 2026 WWB would measure up to that event. So far, it has fallen far short.

The HRRR has gotten the 0z cycle off to a promising start with a deeper, closer, snowier solution across NJ and eastern PA.

Following today's snowfall, somewhat cooler air will move in tonight, setting the stage for another winter event tomorrow. A coastal storm will develop off the Southeast coast and then track toward but perhaps just south and east of the 40N-70W benchmark. In a change from recent days, the latest guidance brings the storm closer to the coast than had previously been shown. As a result, New York City and nearby areas will likely see 1"-3" of snow tomorrow into tomorrow night with some locally higher amounts around 4". There is a risk of mixed precipitation or rain for at least part of the event on Long Island, the Jersey shore, and perhaps into New York City and nearb areas. There remains a degree of uncertainty concerning the storm's track and rate of development. Highs will be mainly in the lower and middle 30s in New York City on tomorrow and Monday. The temperature will fall toward or near freezing during tomorrow's snowfall. Arctic air will move into the region on Monday night. Tuesday could be the coldest day so far this season with highs struggling to reach the lower 20s and lows in the teens in New York City. Suburban areas could see single-digit lows, especially on Wednesday morning. Wednesday will be another unseasonably cold day. Temperatures will remain below normal through at least most of next week. After January 20th, conditions could become more favorable for snowfall, as a generally cold pattern continues. The probability of a PNA+ regime has continued to increase. PNA-related developments would have large implications for snowfall. A persistently positive PNA would have above climatological risk of moderate or significant snowfalls. A mainly negative PNA would favor mainly small snowfalls. The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was -0.8°C for the week centered around January 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.47°C and the ENSO Region 3.4 anomaly has averaged -0.67°C. La Niña conditions will likely continue into at least late winter. The SOI was +27.70 today. The preliminary Arctic Oscillation (AO) was -1.554 today. The PNA was +1.067, which is the highest since November 2, 2025 when the PNA was +1.071. Based on sensitivity analysis applied to the latest guidance, there is an implied near 72% probability that New York City will have a cooler than normal January (1991-2020 normal). January will likely finish with a mean temperature near 32.6° (-1.1° below normal). Supplemental Information: The projected mean would be at the 1981-2010 normal monthly value.

Preliminary snowfall amounts: Central Park: 1.0” JFK Airport: 0.6” LaGuardia Airport: 1.4” Newark: 2.0”

QPF amounts in New York City were in line with the guidance with 0.17" being recorded. Both the NBM and ECMWF fared best. However, 0.16" fell over a 2-hour period rather than the 3-4 hour spread that had been shown on the guidance. On account of the heavier rates, temperatures dropped to the wet bulb temperature (32°) during the height of the precipitation rather than the above freezing figures that had been shown on the guidance.

Three photos from Armonk, NY:

It will probably be closer to 7-8:1, which is much better than what would have been the case had the precipitation been lighter. Outside the City, things are on course and some areas could see ratios near 10:1.
