1843.

At a minimum, they should let the public know when the measurement was made. Next report will be shortly after 1 pm.

That was the 7 am figure.

Larchmont, NY.

Five photos from the ongoing blizzard:

Some snow measurements: Islip: 22.5" New York City-Central Park: 15.1" Newark: 18.3"

Islip: 20.0". That now ranks as Islip's 8th biggest snowstorm on record. Islip's figure will climb higher in the rankings.

Short video from around 5:15 am:

1 W Nesconset and 2 SSE Manorville are leading the way in terms of snowfall with 8.8" and 8.0" respectively so far.

Around 4" when I went to Mamaroneck. Larchmont has about the same.

Two photos from Mamaroneck, NY. The wind is starting to pick up.

Snow is falling quite heavily and the wind is picking up.

That's v.5.0 which is more conservative with snowfall predictions than v.4.3. V.5.0 will become operational this spring.

Correct NBM map. I had accidentally used the entire forecast period.

Good catch. I thought I had excluded them. I will repost the correct image shortly. My apologies.

I'm not sure which model or models are responsible for the snowy Maine NBM figures.

Moderate snow is now falling in Larchmont. There is a solid coating on all surfaces.

A major blizzard is getting underway. A rapidly developing storm will bring heavy snow and high winds to the region into tomorrow afternoon. At present, a 16"-22" snowfall appears likely in New York City and its nearby suburbs. Somewhat lesser amounts are likely north and west of New York City. A 18"-24" snowfall is likely across central New Jersey and part of Long Island. Blizzard conditions are likely at the height of the storm late Sunday night into Monday morning across much of the region. Winds will likely gust near 60 mph creating extremely low visibilities and large drifts. Final estimates: Allentown: 8"-12" Atlantic City: 8"-16" Baltimore: 4"-8" Binghamton: 2"-4" Boston: 18"-24" Bridgeport: 14"-20" Harrisburg: 4"-8" Hartford: 8"-12" Islip: 18"-24" New York City: 16"-22" Newark: 16"-22" Philadelphia: 12"-18" Providence: 18"-24" Scranton: 3"-6" Washington, DC: 3"-6" Wilmington: 12"-18" New York City's 10 Biggest Snowstorms: 1 27.5", January 22-24, 2016 2 26.9", February 11-12, 2006 3 26.4", December 26-27, 1947 4 21.0", March 12-14, 1888 5 20.9", February 25-26, 2010 6 20.2", January 7-8, 1996 7 20.0", December 26-27, 2010 8 19.8", February 16-17, 2003 9 19.0", January 26-27, 2011 10 18.1", January 22-24, 1935 and March 7-8, 1941 As a result, Winter 2025-2026 will become just the 10th winter with two 10" or above snowstorms in New York City. The others are 1895-1996, 1925-1926, 1960-1961, 1977-1978, 1995-1996, 2003-2004, 2009-2010 (3 such storms), 2010-2011, and 2013-2014. Even more impressive, Winter 2025-2026 will be on track to join Winters 1960-1961 and 1977-1978 as the only winters with two or more 10" snowstorms, a seasonal mean temperature of 32° or below and seasonal snowfall of 30.0" or above. The ENSO Region 1+2 anomaly was +0.7°C and the Region 3.4 anomaly was -0.2°C for the week centered around February 11. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.03°C and the ENSO Region 3.4 anomaly has averaged -0.47°C. Neutral ENSO conditions are now developing. Neutral ENSO conditions will develop during the close of winter. The SOI was +6.48 today. The preliminary Arctic Oscillation (AO) was -0.211 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a cooler than normal February (1991-2020 normal). February will likely finish with a mean temperature near 31.6° (4.3° below normal). Supplemental Information: The projected mean would be 3.7° below the 1981-2010 normal monthly value. Overall, Winter 2025-2026 is on track for a seasonal mean temperature of 32.0°. If a 32.0° or below seasonal mean temperature occurs, 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.

The Pennsylvania map for the NBM:

I will post the PA map. Unfortunately, there is no map that zooms in on SE PA, which is surprising given that Philadelphia is a major city.

18z NBM (v.5.0): Note: V.4.3, which will be replaced this spring, shows 25” for Central Park. The newer version with the more realistic snow-liquid ratios has been very steady.

We'll know tomorrow.
