1976-77 didn't make it, because the winter was frigid (28.3° seasonal mean temperature), but seasonal snowfall was below 30.0" (24.5").

Thanks Don. Sorry, I didn't catch that point.  I recall very cold, light, fluffy snowfalls that season; they did last, though.

Records:

Highs:

EWR: 69 (2022)
NYC: 68 (2022)
LGA: 66 (1976)
JFK: 65 (1976)


Lows:

EWR: 0 (1979)
NYC: -5 (1896)
LGA: 2 (1979)
JFK: 5 (1979)

Historical:

 

1894: According to Grazulis, an estimated F2 tornado hits 5 miles south of Warren, Arkansas. An older woman was killed in one of the small homes that were destroyed. In addition, fruit trees were ripped out and carried a half-mile. Another tornado, estimated F3, killed two people in Claiborne County, Louisiana.

 

1926: A deadly avalanche, Utah's worst, demolishes 14 miner's cottages and a three-story boarding house in Bingham Canyon. Thirty-six were killed and 13 injured. 

1930 - Eureka, CA, reported an all-time record high of 85 degrees, a record which lasted until September of 1983. (The Weather Channel)

1936 - The temperature at McIntosh SD plunged to 58 degrees below zero to establish a state record. (David Ludlum)

1958 - The greatest snowstorm of the mid 20th century struck the northeastern U.S. The storm produced 30 inches of snow in interior New England, including more than 19 inches in 24 hours at the Boston Airport. The same storm produced up to three feet of snow in the Middle Atlantic Coast Region, with 14 inches at Washington D.C., and 15.5 inches at Baltimore MD. The storm resulted in 43 deaths and 500 million dollars damage over the Middle Atlantic Coast States. (David Ludlum)

 

1958: From the 14th through the 17th, one of the most significant snowstorms of the mid 20th century struck the northeastern U.S. The storm produced 30 inches of snow in the interior of New England, including more than 19 inches in 24 hours at the Boston Airport. The same storm produced up to three feet of snow in the Middle Atlantic Coast Region, with 14 inches in Washington D.C. and 15.5 inches in Baltimore, Maryland. The storm resulted in 43 deaths and 500 million dollars damage over the Middle Atlantic Coast States.

 

1973: Snow showers moved across southeast Texas, with most locations only reporting snow flurries. However, the Houston Intercontinental Airport measured 1.4 inches of snow.

1987 - A couple of winter storms, one off the Atlantic coast and another over the south central U.S., produced snow and ice from the Mississippi Valley to the Mid Atlantic Coast Region. Freezing rain produced a coat of ice three inches thick in northern South Carolina, and 30,000 homes around Pee Dee were left without electricity. Parts of south central Kentucky were without electricity for three days following the storm, which was their worst in 35 years. (The National Weather Summary) (Storm Data)

1988 - Santa Ana winds in southern California gusted to 63 mph at Ontario. Heavy snow blanketed parts of Colorado, with 11 inches reported at Strontia. (The National Weather Summary) (Storm Data)

1989 - Low pressure off the Washington coast produced more than a foot of snow in the Cascade Mountains, and more than three inches of rain along the Northern Pacific Coast. Spokane WA was blanketed with 13 inches of snow. Cold arctic air in the Upper Midwest produced all-time record high barometric pressure readings of 31.10 inches at Duluth MN, 31.09 inches at Minneapolis MN, and 31.21 inches at Bismarck ND. (The National Weather Summary) (Storm Data)

1990 - The biggest winter storm of the season hit the Pacific Coast Region. In northern California, snow fell along the coast, and two day totals in the mountains ranged up to 67 inches at Echo Summit. Snowfall totals in the mountains of southern California ranged up to 48 inches at Green Valley, with 46 inches reported at Big Bear. Up to two feet of snow blanketed the southern Cascade Mountains of Oregon, and 20 to 35 inches were reported in the northern Cascades of Oregon. Up to ten inches of snow blanketed Seattle WA. (The National Weather Summary) (Storm Data)

Following a foggy start, tomorrow will see highs reach the lower and perhaps middle 40s. Some rain showers or a period of rain is likely later tomorrow into early Thursday as a system streaks rapidly from Minnesota across central New York State and into New England. Parts of central New York State and southern/central New England, including Boston, could see some accumulating snow.

Additional precipitation could arrive Friday or Saturday. Highs will likely reach the 40s through Saturday. 

Numerous ensemble members and operational models continue to suggest the potential for a significant or major snowstorm some time in the February 22-24 timeframe. More evidence in the form of model consensus and support from a large number of individual ensemble members will be needed before there can be reasonable confidence in such a solution. For now, one is dealing with a low probability but high-impact scenario.

An AO-/PNA- pattern, which is forecast for the timeframe involved, has seen a number of significant or major snowstorms during the second half of February. Since 1950, New York City has seen four 6" or above snowstorms during such patterns, including the 1979 President's Day blizzard (12.7") and the February 25-26, 2010 snowstorm (20.9"). In contrast, during AO+/PNA- patterns, New York City has seen just one 6" or above snowstorm. Details should start to become clearer by Wednesday or Thursday.

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 +15.13 today. 

The preliminary Arctic Oscillation (AO) was -0.264 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 97% probability that New York City will have a cooler than normal February (1991-2020 normal). February will likely finish with a mean temperature near 31.5° (4.4° below normal). 

Supplemental Information: The projected mean would be 3.8 below the 1981-2010 normal monthly value. 

Overall, Winter 2025-2026 is on track for a seasonal mean temperature of 31.9°. 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.

For the first time in a LONG time I've got water trickling through my gutter downspouts!  Nice sound I have to say.  Gutters and downspouts have been solid ice for about a month now.  Several houses in the neighborhood have had gutter ice dams cause indoor water damage.  Lots of green Servpro vans in the area doing cleanup.

Yuck, I hope we don't do this over here tonight.

 

Tonight

Areas of dense fog between 10pm and 1am. Widespread dense freezing fog after 1am. Otherwise, increasing clouds, with a low around 30. Calm wind.

It's down to 34 already!

why are some other METS saying the -PNA/AO pattern is not favorable ? You have proof that it is. Maybe someone should point this out to Lee Goldberg - Steve D. and DT

In most cases, December 1 to mid-February, it isn't. But when wave lengths shorten, it becomes more favorable and the snowstorm stats speak for themselves. Two thirds of snowstorms with 10" or more snow in Boston, New York City, and/or Philadelphia during the second half of February occurred with a PNA-.

My whole gutter on the front side of the house is a brick of ice. Luckily no leaks
