The 72.0" through December 23rd is the 4th highest figure through that date. Only 1945, 1976, and 2000 had more. Both 1976 and 2000 had a lot more snow during the remainder of winter. -
Morning thoughts… Following yesterday’s historic drop in temperatures, today will be mostly sunny and very cold. High temperatures will reach the upper teens and lower 20s. Likely high temperatures around the region include: New York City (Central Park): 19° Newark: 21° Philadelphia: 21° Despite sunshine, it will again be very cold tomorrow. Normals: New York City: 30-Year: 42.1°; 15-Year: 43.0° Newark: 30-Year: 42.6°; 15-Year: 43.7° Philadelphia: 30-Year: 43.9°; 15-Year: 44.9° The last time New York City had a high temperature in the teens was January 31, 2019 when the high was 16°. The last time New York City had a high in the teens in December was December 28, 2017 when the temperature topped out at 17°.

It will be tough, but we have a realistic shot at it. -

New York City had a temperature of 18 at 6 pm EST. The high was 58. This is just the 19th day with a 40-degree or above daily range (0.03% of days in the climate record). The last 40-degree range occurred on December 22, 1998 when the mercury fell from 63F to 22F. -
High winds are continuing to blast frigid air into the region. At Central Park, the temperature has tumbled from an early high of 58° to 21° at 5 pm. The 37° range is among the top 0.09% of observations since recordkeeping began in 1869. Temperatures will bottom out in the lower teens in New York City tonight. There remains a modest chance (approximately 25%) that the mercury could reach the single digits in Central Park. Numerous locations outside New York City will likely see single-digit lows. Tomorrow will see the mercury struggle to reach 20° in New York City. Sunday will be fair and continued very cold before slow moderation commences early next week. The first week of January will likely see much above normal temperatures. The ENSO Region 1+2 anomaly was -0.1°C and the Region 3.4 anomaly was -0.9°C for the week centered around December 14. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.95°C and the ENSO Region 3.4 anomaly has averaged -0.92°C. La Niña conditions will likely persist through mid-winter. The SOI was +50.96 today. That broke the daily record of +44.34 from 2003. It was also the second consecutive +50 reading. Only February 16-17, 2011 and April 1-2, 2011 had two consecutive days on which the SOI was +50 or above. The preliminary Arctic Oscillation (AO) was -3.323 today. On December 21 the MJO was in Phase 4 at an amplitude of 1.354 (RMM). The December 20-adjusted amplitude was 0.792 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 86% probability that New York City will have a colder than normal December (1991-2020 normal). December will likely finish with a mean temperature near 37.4° (1.7° below normal).

Front is coming through with high winds and some rain in Larchmont, NY. -
Near the start of January or just afterward, if the ensembles are correct.

It could be a week later. Afterward, it's difficult to associate it with the blocking. P.S. Buffalo has seen the passage of the Arctic cold front. There is currently heavy lake effect snow with 1/8 mile visibility.

It is remarkable. This would be a rare event.
