I'd want to experience the 1780s for this and also for that volcanic eruption in Iceland that caused the mammoth winter of 1782-83 which I'm convinced was more snowy than any winter that has happened since.

 

No snowfall measurements from that winter anywhere?

 

The winter of 1797-1798 must have pretty solid as well. Fine sleighing conditions, no doubt. The Tidewater Region probably had more snow in this 10-day stretch than they've had in the entire 21st century.

100 inches of snow in 10 days in Norfolk, Va? WOW !

and the revenge of the coastal in the second snow storm, 40 inches in Norfolk in one night and 0 inches 25 miles inland!

Hope that doesnt greenlight another dumping of road salt

100% agree. Im looking forward to the rain to finally get rid of it all.

Parts of the Great Lakes region saw exceptional warmth today. Some highlights:

Green Bay: 53° (old record: 42°, 1989)
La Crosse: 58° (old record: 48°, 1890 and 1931) ***New January monthly record***
Madison: 57° (old record: 47°, 1974)
Milwaukee: 56° (old record: 53°, 1988)
Minneapolis: 52° (old record: 48°, 1879 and 1989)
Prairie du Chien: 60° (old record: 52°, 1903)
Rochester, MN: 56° (old record: 48°, 1919)
Waupaca: 56° (old record: 47°, 1974)

Some of this warm air will sweep into the Northeast tomorrow. As a result, January will end with a rebound in temperatures. New York City will see temperatures reach the lower and middle 40s. Farther south, Washington, D.C. could have a high in the middle or perhaps upper 50s.

Rain will also develop. New York City and Philadelphia will likely see a general 0.25"-0.75" rainfall. Upstate New York State and northern New England could see snow and ice.

January 2025 is on course to become New York City's coldest January since January 2022. January 2022 had a mean temperature of 30.3°. January 2022 was far snowier with 15.3" monthly snowfall in New York City vs. 2025's 3.0". In contrast, January 2024 (2.3") and January 2023 (Trace) saw even less snowfall than January 2025. In fact, five of the six past years have seen less snowfall in New York City than January 2025.

The first few days of February will see cooler readings, but moderation will follow after the coming weekend.

The AO is now positive and is expected to remain predominantly positive through at least the first week of February. As a result, prospects for a 6" or above snowstorm in the New York City area will be limited. Since 1950, just 2 of 19 (11%) of storms with an AO of +2.000 or above during January 15-February 15 saw 6" or more of snow in New York City. Opportunities for a 6" or above snowstorm could persist for parts of southern New England, including Boston, through the first week of February. There is substantial uncertainty concerning the AO following the first week of February. The spread among ensemble members is currently a remarkable 8 sigma.   

The ENSO Region 1+2 anomaly was -0.4°C and the Region 3.4 anomaly was -0.9°C for the week centered around January 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.08°C and the ENSO Region 3.4 anomaly has averaged -0.80°C. La Niña conditions are underway and will likely persist into the start of spring.

The SOI was +11.83 yesterday.

The preliminary Arctic Oscillation (AO) was +0.425 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a colder than normal January (1991-2020 normal). January will likely finish with a mean temperature near 31.0° (2.9° below normal).

36 / 35 light rain - salt cleansing.  Low 40s today.  Overall look to ride near normal to slightly above in a back and forth caught  on the line of the colder air to the north and much warmer to the south.  Some stronger warmth on the 5-7 balanced out by colder.

Historical:

 

1911 - Tamarack, CA, was without snow the first eight days of the month, but by the end of January had been buried under 390 inches of snow, a record monthly total for the U.S. (The Weather Channel)

1949 - The temperature at San Antonio, TX, plunged to a record low of one degree below zero. Helena MT reached 42 degrees below zero. (David Ludlum)

 

1950: Seattle, Washington experienced their coldest temperature on record with a reading of zero degrees.

1966 - A blizzard struck the northeastern U.S. When the storm came to an end, twenty inches of snow covered the ground at Washington D.C. (David Ludlum)

 

1979: A winter storm that started on the previous day and ended on this day spread 2 to 4 inches of rainfall in 24 hours over much of coastal Southern California and two inches of snow in Palm Springs. Snow fell heavily in Palm Springs, and 8 inches fell at Lancaster. All major interstates into Los Angeles were closed. Snow drifts shut down Interstate 10 on both sides of Palm Springs, isolating the city. 

1982 - A snowstorm struck Missouri, Illinois and Indiana. Twenty-five inches of snow at Greenville IL, located east of Saint Louis, paralyzed the community. The storm left 4000 motorists stranded for two days. (David Ludlum)

1987 - A storm in the Pacific Northwest produced wind gusts to 85 mph in Oregon, and nearly two inches of rain in twelve hours in the Puget Sound area of Washington State. Ten inches of snow at Stampede Pass WA brought their total snow cover to 84 inches. (National Weather Summary) (Storm Data)

1988 - Thirty-one cities in the central and northeastern U.S. reported new record high temperatures for the date, with many occurring during the early morning hours. Temperatures in western New York State reached the 60s early in the day. Strong northerly winds in the north central U.S. produced wind chill readings as cold as 60 degrees below zero in North Dakota. (National Weather Summary)

1989 - The barometric pressure at Norway, AK, reached 31.85 inches (1078.4 mb) establishing an all-time record for the North American Continent. The temperature at the time of the record was about 46 degrees below zero (The Weather Channel). Severe arctic cold began to invade the north central U.S. The temperature at Great Falls MT plunged 85 degrees in 36 hours. Valentine NE plummeted from a record high of 70 degrees to zero in just nine hours. Northwest winds gusted to 86 mph at Lander WY, and wind chill readings of 80 degrees below zero were reported in Montana. Sixty-four cities in the central U.S. reported record highs for the date as readings reached the 60s in Michigan and the 80s in Kansas. (National Weather Summary) (Storm Data)

1990 - High winds in Montana on the 28th, gusting to 77 mph at Judith Gap, were followed by three days of snow. Heavy snow fell over northwest Montana, with up to 24 inches reported in the mountains. An avalanche covered the road near Essex with six feet of snow. Snow and high winds also plagued parts of the southwestern U.S. Winds gusted to 54 mph at Show Low AZ, and Flagstaff AZ was blanketed with eight inches of snow.

The Blizzard of 1966 doppped 6.8 inches of snowfall at NYC

 

Relatively less than other areas of the mid atlantic and north who measures 1 - 2ft.

The warmer ending to January pushed the local 7 station average up to 30.7° or a -1.8° departure. The last time all 7 stations finished below 30° in January was back in 2014. The most recent January that all 7 stations finished under 26° was back in 2004. Other Januaries averaging under 26° were 1994, 1982, 1981, and 1977. So while we have had a few slightly colder Januaries since the 15-16 super El Niño like 2022 and 2018, the coldest January temperatures and departures have been missing the area.

EWR…31.1°…..-1.7°

NYC...30.9°….-2.8°

LGA….32.0°….-2.4°

JFK….32.7°….-0.2°

HPN…28.0°….-1.9°

BDR…29.9°….-1.5°

ISP…..30.1°……-1.8°

AVG…30.7°…..-1.8°
