November 2025 OBS Discussion

[the_other_guy]

i’m trying to remember a Thanksgiving or Christmas week in the last 20 years when we have not had a day that was 58 with rain and mist. 

Let’s see if these winds fuck up the parade tomorrow

[SACRUS]

 

58 / 55 cloudy -  0 .72 in the bucket.  Clearing and the warmest day will at least the next week to 10 days 12/4.   Colder 11/27 - early next week.  Then caught between the deeper cold and ridging to our south - could spell some opporuutunities for early season snow/mixes.  Otherwise looks a bit back and forth bias cold through the next 10 days.

Historical:

 

1703: 400 windmills were destroyed by the greatest gale in the history of England caused by an intense low that passed just north of London. Many of the huge structures burned down from fires which started as their blades turned wildly in 80 mph winds. In London, roofs blew off and chimneys were toppled. The famed Eddystone Lighthouse was toppled by heavy seas. 123 people died on land, and another 8,000 died at sea as hundreds of vessels from the British fleet were lost, including four Men-Of-War. (Ref. Wilson Wx. History)

1888 - A late season hurricane brushed the East Coast with heavy rain and gale force winds. The hurricane passed inside Nantucket and over Cape Cod, then crossed Nova Scotia. (David Ludlum)

1896 - Snow and high winds hit the Northern Plains and the Upper Mississippi Valley, with a Thanksgiving Day blizzard across North Dakota. The storm was followed by a severe cold wave in the Upper Midwest. The temperature at Pokegama Dam MI plunged to 45 degrees below zero. (David Ludlum)

1950: Boston, Massachusetts on the 25th and 26th had a great easterly gale that caused $15 million damage. The strongest one minute average wind velocity was from the southeast at 80 mph. (Ref. NOAA Boston Weather Events)

1965: Snowstorm across northern U.S. with 14.7 inches at Duluth, MN 13.6 inches at Grand Rapids. (Ref. AccWeather Weather History)


1974: A record early snow hit Caribou, ME with 22.3 inches falling in 24 hours and a storm total of 30 inches. This storm was the major contributor to Caribou's snowiest November on record at 34.9 inches. (Ref. AccWeather Weather History)

1979: 74° on 25th and 26th are high point of 12-day warm spell 18th-29th in Washington, DC. (Washington Weather Records - KDCA)
A strong cold front moved through the Mid Atlantic during the afternoon bringing thunderstorms and gusty winds. Kutztown, PA reported a gust to 70 mph, Reading, PA gusted to 65 mph, Allentown, PA gusted to 62 mph and Philadelphia, PA reported a gust to 59 mph. The gusts tore the roofs or portions of roofs off houses and other buildings. Many trees were uprooted or broken off. Rain ruined a large amount of chemicals when the roof of a storage building was blown away. (Ref. Wilson Wx. History)

1983: A major snowstorm hit from Colorado to Wisconsin through the 28th. A fairly consistent 1 to 2 feet of snow was reported. Sydney, NE had the most with 27 inches. Blizzard conditions prevailed with wind gusts as high as 60 mph. Limon, CO reported near zero visibility in snow and blowing snow for a solid 24 hours. (Ref. AccWeather Weather History)

1984: Copper City Utah:n an 18-hour period, the South Jordan and Copper City areas received 20 inches snow, while the eastern parts of the valley picked up only a couple of inches. (Ref. AccWeather Weather History) (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)
 

1987 - A Thanksgiving Day storm in the northeastern U.S. produced heavy snow in northern New England and upstate New York. Snowfall totals in Maine ranged up to twenty inches at Flagstaff Lake. Totals in New Hampshire ranged up to 18 inches at Errol. Gales lashed the coast of Maine and New Hampshire. A second storm, over the Southern and Central Rockies, produced nine inches of snow at Kanosh UT, and 13 inches at Divide CO, with five inches reported at Denver CO. (The National Weather Summary) (Storm Data)

1988 - Thunderstorms produced severe weather over the Central Gulf Coast States during the late morning and afternoon hours. Five tornadoes were reported in Mississippi, with the tornadoes causing a million dollars damage at Ruleville, and in Warren County. In Utah, the town of Alta was blanketed with 15 inches of snow overnight, and during the day was buried under another 16.5 inches of snow. (The National Weather Summary) (Storm Data)

1989 - A massive storm over the western U.S. produced heavy snow in Utah, Colorado, Wyoming and Montana. The storm produced more than two feet of snow in the higher elevations of northern and central Utah, bringing more than sixty inches of snow to the Alta Ski Resort in the Wasatch Mountains. Winds in Utah gusted to 60 mph at Bullfrog. The storm brought much needed snow to the ski resorts of Colorado, with 19 inches reported at Beaver Creek.

From the NWS OKX AFD:

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Key points

* Winds of near 20 mph with gusts near 35 to 40 mph forecast for
  Thanksgiving. High temperatures Thanksgiving mainly low to mid 40s
  but wind chills stay in the 30s.

* Winds of near 25 mph with gusts near 40 to 45 mph forecast for
  Friday. There is still some model indication of near 50 mph
  wind gusts being possible. High temperatures Friday mainly in
  the upper 30s to lower 40s with wind chills staying mostly in
  the 20s to lower 30s.

The key points with the short term will be gusty winds and with the
higher winds, cold temperatures as well as wind chills. No
measurable precipitation is expected during the timeframe of
Thanksgiving through Friday night. There could be a few light
rain/snow showers with strong mid level vorticity maximum
pushing across on Friday. A much colder airmass will be across
the region during the short term.

In the wake of the storm that brought rain to the region last night into early today, colder air will rush into the region tonight.

The closing days of November will be much colder. There is potential for New York City's Central Park to experience its first freeze of 2025. The 1991-2020 normal first data is November 21. The 1961-1990 baseline was November 11. Last winter's first freeze occurred on November 30.

The opening days of December will turn somewhat milder. However, colder conditions could begin to develop during the second half of that week and then continue into or through the second week of December. Severe cold appears unlikely through at least the first 10 days of December. 

The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was -0.7°C for the week centered around November 12. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.16°C and the ENSO Region 3.4 anomaly has averaged -0.65°C. La Niña conditions will likely continue through at least mid-winter.

The SOI was +20.23 today. 

The preliminary Arctic Oscillation (AO) was -0.232 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied 94% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 46.9° (1.1° below normal). 

Supplemental Information: The projected mean would be 0.8° below the 1981-2010 normal monthly value.

Already 40kt KMPO.  Difficult to believe we won't have  fair amount of G40 kt Friday as the very cold trough aloft sweeps by and can in its wake arrives with flurries.  No time for a thread today.

A record number of days this year for gusts over 40mph with so many lows racing through the Great Lakes.

 

 

[wdrag]

Thanksgiving prevails... Create new family memories and think about those who cannot be with us.

Still contemplating a thread for Friday... I think there will be wind gusts to 40 kt at all the airports, but may be will fall short by 3KT. Marginal except if you have no power. 

Also even though its not in most forecasts, I'll be looking for many flurries in NYC metro Fri afternoon.

Great insight as usual Walt. NWS OKX AFD seems to be on the fence in issuing a wind advisory for Friday and does mention a slight chance of showers/flurries. I highlighted the passage to make it easier:

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Key Point

* Friday winds gust to 40 to 45 mph, possibly higher, close to
  50 mph at times.

* Friday still very cold with high temperatures upper 30s to
  lower 40s. Max wind chills mostly in the lower 30s.

The low in Quebec makes its way towards the Canadian Maritimes
without much change in strength with its central low pressure on
Friday. The pressure gradient during the day Friday between
this low and high pressure well to the southwest becomes the
most tight, indicating an even more gusty westerly flow. This
will be conveyed through a deeper mixing layer and steeper lapse
rates which are shown in the forecast model BUFKIT soundings.
There is some indication also of some narrow sliver of elevated
CAPE and with positive vorticity advection could have a few rain
and/or snow showers for parts of the region. POPs are just
slight chance for this.

The core of the 850mb cold pool will be across the region so made
some adjustments to NBM to account for this. Went higher than NBM
for clouds and POPs as well as winds and lower than NBM for
temperatures. NBM 90th percentile winds were used and even with
these were manually adjusted up to better match up with
forecast soundings from BUFKIT especially with deep vertical
mixing. The current forecast has wind gust maxima of 40 to 45
mph, just below wind advisory criteria. Cannot rule out a few
wind gusts to wind advisory thresholds, near 50 mph Friday.

At this time, still too early and not high enough confidence to go
with wind advisory for Friday but chances are slowly trending
up. 06Z MAVs have trended slightly higher with sustained winds
Friday afternoon for some sites compared to the 00Z MAVs. Would
also like to see LAMP gusts indicate some mid to upper 30s for
wind gusts to increase confidence in wind advisory for Friday.
BUFKIT already indicating a few spots late afternoon into
evening mix up to near 800mb with 45 kt at top of mixed layer.
The 40kt wind gust potential in the HRRR fields has expanded
comparing the 00Z HRRR run to the 06Z HRRR run. The wind gust
potential with the 00Z run only indicated some areas of 35-40 kt
wind gust potential within the region for Friday mainly in the
easternmost part of LI Sound and now covers most of LI Sound and
along more coastline. Forecast high temperatures Friday are
mostly in the upper 30s to lower 40s with wind chills at most in
the lower 30s for most locations.

[SACRUS]

45 / 22 clouds slicing NW-NJ with partly cloudy sotheast of there.  Cooler/colder next 5- 7 days overall and a few storms/systems (Sunday / Tuesday) to see how they evolve.  Overall a back and forth beyond there likely weighted below normal.

1701:Anders Celsius, the astronomer who invented the Celsius, often called the centigrade thermometer scale was born on this date.

1883 - Fire engines were called out in New York City and New Haven, CT, as a result of the afterglow of the sunset due to vivid red ash from the Krakatoa Volcano explosion in August. (The Weather Channel)

1898 - The Portland storm raged across New England producing gale force winds along the coast and heavy snow inland. A foot of snow blanketed Boston MA, and 27 inches fell at New London CT. Winds at Boston gusted to 72 mph, and wind gusts to 98 mph were estimated at Block Island RI. A passenger ship, the S. S. Portland, sank off Cape Cod with the loss of all 191 persons aboard, and Boston Harbor was filled with wrecked ships. The storm wrecked 56 vessels resulting in a total of 456 casualties. (26th- 28th) (David Ludlum) (The Weather Channel)

 

 

1912: Northern Florida on November 27th and 28th : The only recorded November occurrence of snowfall in northern Florida. Traces of snow are reported in Blounstown, Tallahassee, Marianna and Mt. Pleasant measured 0.5 inches (1.2 cm). (Ref. AccWeather Weather History)

1919: Very cold air covered areas from the northern Plains, Rockies to the West Coast. Cheyenne, WY recorded a high of -4° which still remains the earliest day of the season that the temperature remained below zero. Some record low temperatures for the date included: Grand Forks, ND: -16°, Clayton, NM: -1° and Medford, OR: 13°. (Ref. Wilson Wx. History)

1938: The second heavy snowfall to hit the Northeast in three days dropped a foot in parts of New Jersey and 14 inches in parts of New York. The snow in New England was the heaviest November snowfall since the Portland Storm of 1898. Philadelphia, PA reported 6.9 inches of snow, their greatest snow for any November day. 4.3 inches on the 25th and 7.2 inches from the 26th through this date brought the total of 11 inches on the ground in Philly. Washington, DC set a daily snowfall record with 6.8 inches on the 25th.
(Ref. AccWeather Weather History)

1977: Canadian high pressure brought scattered record lows from the Lakes to North Carolina while high pressure over Idaho generated offshore winds in southern California bringing some record highs. Sparta, WI fell to -18°, their coldest November temperature. Other record lows included: Grand Rapids, MI: 5°, Muskegon, MI: 5°-Tied, Bristol, TN: 15° and Raleigh, NC: 19°. (Ref. Wilson Wx. History)

1983: The barometer dropped to 28.17 inches over the Netherlands as an intense area of low pressure moved in from Ireland and England. The reading is the country's lowest pressure on record. (Ref. AccWeather Weather History)

1985: Cold hits northern Minnesota. 30 below zero at Crookston, MN. (Ref. AccWeather Weather History)

1987 - Wet weather prevailed across much of the nation east of the Rockies. Sunny and cool weather prevailed in the western U.S. Snow fell in the central U.S., with totals in Kansas ranging up to six inches at Burr Oak. Much of the area from central Oklahoma to southwestern Minnesota experienced its first snow of the winter season. (The National Weather Summary)

1988 - Snow and high winds created blizzard conditions in Minnesota. Winds gusted to 63 mph at Windom, and snowfall totals ranged up to 14 inches at Aitkin. Snow drifts seven feet high closed many roads. Fargo ND reported a wind chill reading of 34 degrees below zero. (The National Weather Summary) (Storm Data)

1989 - A storm system crossing the north central U.S. spread snow across the Dakotas and Minnesota. Heavy snow fell in western South Dakota, with 18 inches reported at Galena. Strong winds associated with the storm gusted to 50 mph in the Great Lakes Region and the Great Plains, with blowing dust reported in Kansas. Thunderstorms associated with the same storm system produced damaging winds in Michigan, Ohio and Indiana during the evening, with gusts to 73 mph reported east of Ypsilante MI. Unseasonably warm weather prevailed ahead of the cold front. Twenty-three cities from the Gulf coast to the Ohio Valley and the Mid Mississippi Valley reported record high temperatures for the date, including Saint Louis MO with a reading of 76 degrees. (The National Weather Summary) (Storm Data)

1990: Indian summer heat over Eastern half of U.S. set over 70 records broken over 2 days. (Ref. Wilson Wx. - Has many additional temperature records.)

1993: Barcroft Hills Weather Center in a 20-hour rain had a total of 4.95 inches on 27th & 28th, which set a new 20-year record. (Ref. Annandale Weather Records)

1994: Chicago, IL received a trace of snow making this their latest date for the first snow of the season. Their normal first snow occurs on October 30th. High pressure brought chilly weather to southern California. Bishop, CA tied their daily record low with 9° and Long Beach, CA set a new record low with 38°. Shreveport, LA tied their record high with 82°. (Ref. Wilson Wx. History)

1995: A major winter storm lashed the southern two thirds of Wisconsin with thunder, heavy snow of 6 to 14 inches between Milwaukee and Madison, sleet, freezing rain, strong gusty winds, and near-blizzard whiteout conditions. Preceding the snow over southern Wisconsin there was a two to six hour period of sleet and/or freezing rain which glazed road surfaces. This was a dangerous storm which was forecasted two days in advance. The path of the responsible low pressure was from northern Missouri to southern Ontario, Canada. Some snowfall locations in Wisconsin included: Lone Rock: 11 inches, Richland Center: 10 inches, Owen: 8 inches, Mondovi: 7 inches and Viroqua: 6 inches. (Ref. Wilson Wx. History)

2001: A powerful winter storm, the first of the season, dumped between 3 and 8 inches of snow across portions of central and southwest Oklahoma. Isolated reports of up to 10 inches were reported across western north Texas. By the next day, Lawton, OK had 6 inches on the ground, while Munday, TX had accumulated 14 inches. A few locations across North Carolina reported record high temperatures for the date including: Charlotte, NC: 77°, Greensboro, NC: 74°-Tied and Asheville, NC: 72°. (Ref. Wilson Wx. History) (26th-27th)
A convective snow band stayed almost stationary for approx. 12 hours today over parts of Central MN into West Central WI; many snowstorm totals > 20 inches. Willmar, MN was buried under 30.4 inches of snow. 20 inches of the total fell in a 24-hr period, thus setting its 24-hr record. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)
 

2005 - A major winter storm affected parts of Nebraska and the Dakotas during the 27th-28th. Snowfall accumulations of 16-20 inches were observed in parts of eastern South Dakota, while wind gusts exceeding 60 mph also accompanied the snow, creating blizzard conditions. Thousands of power outages were caused by the combination of strong winds and heavy snow. In South Dakota, about 8,000 utility poles and 10,000 miles of transmission line were brought down by the storm (Associated Press).
