An exceptional early-season Arctic outbreak has delivered record-breaking snow across the U.S. Midwest and eastern Canada, bringing the heaviest early-November accumulations in decades and snarling transport from Cincinnati to Ottawa.

In the U.S., Cincinnati picked up 2.1 inches (5.3 cm) on Nov 10 — the most snow ever recorded on that date, according to the NWS. The previous record, 0.3 inches (0.8 cm) from 1948, stood unchallenged for 77 years.

Nearby Dayton saw 3.6 inches (9.1 cm), crushing its 1960 record of just 0.2 inches (0.5 cm). Minimums fell into the low 20s (around -6C), with wind chills in the teens (-10 C), marking one of the coldest early-November nights in decades.

A myriad of regions posted their earliest snowfalls on record, including in South Carolina’s Myrtle Beach and Florence.

North of the border, Ontario saw one of its snowiest early-November stretches on record.

An early-November Arctic blast has busted temperature records across the U.S. Southeast, from Florida’s Gulf Coast to North Carolina’s Outer Banks, delivering the region’s coldest/earliest start to winter in decades.

In Florida, Punta Gorda plunged to 39F (4C), breaking its previous record by 5F and marking the coldest this early since 1966. Naples fell to 44F (7C), besting its 1993 record by 3F, while Tampa Bay hit 39F, its coldest November 11 since 1892. Vero Beach (40F), Fort Pierce (41F), Orlando (36F), Daytona (35F), Leesburg (35F), and Melbourne (37F) all set or tied daily records.

Tuesday morning marked the coldest statewide reading this early in nearly 60 years.

Mount Washington is off to a strong start this winter.

A November 17 storm added 6.7 inches, pushing the month’s total to 42.5 inches — well above the long-term mid-November average of 35.6 inches, according to the Mount Washington Observatory.

Snow began in early October, and a run of powerful storms hit the summit through early-November — a foot by Nov 5.

Back in 2013, Boston Magazine warned the New England ski industry was “melting away” and insisted “winter is not coming:”

A powerful early-season storm is hammering the Great Lakes.

Heavy lake-effect snow bands from Michigan to New York are forecast through Friday, with blizzard conditions around Lake Superior’s south shore.

A blizzard warning is in place for Michigan’s Keweenaw Peninsula, where Houghton and surrounding areas are forecast up to 3 feet of snow and whiteout travel. Lake-effect bands could drop even more across other traditional snowbelts.

AccuWeather’s ‘Local StormMax’ is also calling for 3 feet in the core bands.

While north of the border, prolonged snow squalls will persist across the likes of southern Ontario, with 20–40+ cm (8–16+ in) and locally higher totals through Thursday–Friday.

Cold is spreading too — much of the CONUS turns ‘purple’ by Monday (Dec 1):

A strong negative East Pacific Oscillation (-EPO) is locking in over the North Pacific, setting the stage for repeated Arctic blasts into the U.S. through mid-December.

The ECMWF (below) shows a massive cold pool forming over Alaska and western Canada — a Polar Vortex dump pattern. Strong high pressure over Alaska forces cold air down the Rockies into the Midwest and Great Lakes, then eastward.

A recent stratospheric-warming disruption is reinforcing the setup, with another warming pulse projected in 10-or-so days.

Fast-moving systems continue to run the Gulf of Alaska track into the Pacific Northwest, feeding Alberta Clippers that spread quick, accumulating snow across the northern tier.

With Arctic air in place, even small disturbances can produce wintry precipitation from the Midwest to the Mid-Atlantic.

Temperatures are already dropping sharply across the central U.S. (map below), and the model signal only strengthens: a sustained funnel of cold linking Alaska to the Northeast, with multiple waves of subfreezing air arriving through mid-month.

Any brief Pacific warmup is likely to be overwhelmed by the size and depth of the cold pool.

Rug up America.

A total of 8.4 inches of snow fell at O'Hare International Airport on Saturday alone, setting a new record for the snowiest November day in Chicago.

The 8.4-inch total broke the daily snowfall record for Nov. 29 of a mere 3 inches set in 1942.

The snowfall total also set a record for any November day in Chicago. The old record was 8 inches even on Nov. 6, 1951.

The 8.4-inch snow total from this one snowstorm is the second highest single-day total at all at O'Hare since Jan. 1, 2015.

As to the total from this snowstorm, it was still climbing Sunday morning. As of 6 a.m., a total of 8.5 inches of snow had fallen at O'Hare.

Chicago has just logged one of its harshest openings to winter in nearly half a century.

Snowfall at O’Hare reached 17.1 inches as of Dec 7. The last time the city piled up more snow by this point was back in 1978.

Almost all of this season’s total has arrived in the past nine days. From Nov 29 to Dec 7, O’Hare picked up 15.4 inches (with Chicago posting its snowiest-ever November day on Nov 30) — one of the most intense nine-day stretches on record. In fact, only 1967 has delivered a snowier stretch (with 29.9 inches).

Cold reinforced the setup. Sunday night dipped below 0F, with additional lake-enhanced snow pushing totals even higher across the region. Midway logged another 4.3 inches Sunday; O’Hare added at least 4.6 inches, with more on the way later this week.

This echoes the broader theme for the United States, particularly across the Midwest and Rockies. The Northwest is next to be placed under heavy-snow warnings. And Alaska has received the heaviest confirmed totals. Juneau broke records on Sunday, part of the system that delivered roughly 20 inches to nearby Hyder and as much as 18 inches across the Skagway–Haines corridor.

Sacramento International Airport has now gone more than 190 hours without rising above 46F (8C), an early-winter chill the region hasn’t endured in more than 30 years.

Daily maximums have been stuck in the mid-40s since last week, held down by an entrenched layer of low cloud and persistent valley inversion, with California’s Central Valley stuck in a pattern more reminiscent of mid-winter than early December.

The stagnation is showing no sign of breaking, extending one of the longest, coolest runs on record.

The first 10 days of December have also delivered a top-tier cold start across the East and the Great Lakes.

Mean temperatures are running 7F to 15F below average across a broad swath from Minnesota to Maine and down through the Mid-Atlantic, with widespread double-digit departures. A few spots have posted their coldest Dec 1 - 10 on record.

Most of the eastern half of the U.S. is locked well below normal — the lone exception being the Florida Peninsula.

https://www.sott.net/article/503445-Prehistoric-Lake-Manly-returns-to-Death-Valley-after-record-rainfall
An ancient lake has reemerged after Death Valley National Park experienced record-breaking rainfall this fall.

From September to November, Death Valley, located in California and Nevada, received 2.41 inches of rain, making it the national park's wettest fall, according to a news release on the park's website. In November alone, the park received 1.76 inches of rain, breaking the previous record of 1.7 inches set in 1923.

Due to the rains, Lake Manly, which dates back to the Ice Age, has formed once again in the Badwater Basin, the lowest point in North America, which lies 282 feet below sea level. But the lake isn't very deep.

"The lake, colloquially known as 'Lake Manly,' is much smaller and shallower than the one that formed after the remnants of Hurricane Hilary passed through the park in 2024," the national park said. "The water is about a mile from the Badwater parking lot and in most places would not rise above the tops of your shoes."



Here's what to know about the record-breaking rains.

What is Lake Manly?

In California, less than 100 miles away from the California-Nevada border, Badwater Basin, which is normally a dry salt flat, became home to the shallow lake locally known as Lake Manly due to the record rainfall.

The lake dates back to the ice age, and is the remains of a prehistoric lake that was once 80 miles long and 600 feet deep, according to the Palm Springs Desert Sun, a part of the USA TODAY Network. The lake was filled by glacial meltwater and seasonal streams.

It was home to a flourishing ecosystem, but today, it barely tops a few inches and is located in one of the country's harshest environments.

"Normally, the amount of water flowing [into Death Valley is] much less than the evaporation rate," park ranger Abby Wines previously said in a statement in 2024 after the valley floor received 4.9 inches of rain in six months.

Usually, the Death Valley National Park receives an average of 2 inches of rain per year, according to the National Park Service.

A week-long lake-effect siege has buried large swaths of the Great Lakes, capping off 2025 with deep, disruptive snow and more still falling into the New Year.

Syracuse, New York has already logged 76 inches of snow this season, nearly double its annual average.

One single burst delivered more than 24 inches in a day, marking the city’s second-snowiest day on record and its snowiest December day ever. Western and upstate New York remain under a state of emergency as road crews struggle to keep pace.

Arctic air continues to pour across the comparatively warm waters of Lakes Erie and Ontario, locking narrow but intense snow bands in place. In Redfield, snowfall rates hit 5 inches per hour.

Tug Hill Plateau is forecast to receive near 3 feet by Saturday. Areas south of Buffalo face a foot. With parts of Pennsylvania seeing the same before the system finally weakens. More is on the way though, with January offering little sign of relief.

Snowfall in Juneau over the past week has smashed records for the city and borough, bringing avalanche risks and sunken vessels.

The previous record of 54.7 inches was set back in 1964, and this December will close with over 80 inches of snowfall. A typical year for Juneau brings about 80 to 81 inches of snowfall.

Nicole Ferrin from the NWS told reporters Wednesday that Juneau has broken the five-day snowfall record, the previous record being set in April 1963 with 45.9 inches.

"As of midnight last night, we had gotten to 46.8 inches at the airport," Ferrin said. "So we surpassed the previous longest record snow event at the Juneau Airport."

She states that no further major snowfall is expected over the next few days, but temperatures will drop.



Avalanche Risks

The city of Juneau issued an alert for elevated avalanche conditions on Tuesday afternoon to residents living downtown. The alert was not an evacuation advisory, but rather a preparation alert, just in case conditions continue to worsen and there is a need to evacuate.

Thane Road has been closed since Tuesday night due to the high avalanche hazard. Pat Dryer with the Alaska Department of Transportation & Public Facilities states that they plan to conduct avalanche hazard reduction above Thane Road on Thursday, Jan. 1, between 11 a.m. and 2 p.m.

Dryer states that avalanche reduction involves artificially triggering avalanches. Dryer said they will use a device called a DaisyBell rather than explosives.

"We have several different mediums to do that with, one of which is a helicopter with a device that is transported below it. You can use explosives as well, and another option is road closures and mitigations," Dryer said.

This work is intended to reduce the risk of larger avalanches impacting Thane Road. If avalanche debris reaches the roadway, an extended closure may be necessary to remove debris safely.

Updates will be posted here.

Earlier this week, the city created a new avalanche advisory page where there is no longer a 5-point scale. Instead, the city will be using a more direct scale, as advised by local experts.

"On our current avalanche advisory page, folks can see whether or not we're at a low risk, elevated risk or high risk of avalanche danger that really corresponds directly to that 'Ready, Set, Go,'" Ryan O'Shaughnessy with the City & Borough of Juneau Emergency Programs stated.

In parts of Alaska, winter’s cold has reached historic levels.

At 7:30 PM Thursday, Fairbanks officially climbed to 0F (-17.8C) for the first time in 32 days, ending a subzero stretch that began Dec 13, 2025. That now stands as the longest consecutive period below zero in Fairbanks in 108 years, since the run of 40 ending Jan 3, 1918:

Snowfall has also been exceptional across Alaska this winter.

Juneau shattered long-standing snowfall records in December, with totals so extreme that nearly a full winter’s worth of snow fell in a single month. Fairbanks has also logged abnormally heavy snowfall alongside its historic cold.
Across much of Canada too, deep Arctic air has been established, with repeated cold pools rotating through the Prairies, central provinces, and eastern regions. This reservoir of cold has not yet been fully discharged southward, but the upper-level pattern now looks to be evolving. The ‘warm-up’ in Fairbanks (to 0F!) could further hint at this—at the cold beginning a sag southward.

The cold is primed, the pattern is aligned, and the border no longer looks to be a barrier...

[Mark]

Alaska is locked in one of its coldest winters in more than a century, with the Lower 48 next in line.

As mentioned last week, Fairbanks held below -19C (-2F) from Dec 13 through Jan 16 — a stretch of sustained cold not seen in over 100 years of observations (since 1918).

That Arctic reservoir is destabilizing, with its cold now set to spill south into the CONUS in what is shaping up to be the most severe winter outbreak in decades.

The models converge on a large, long-duration event beginning this weekend and intensifying through the final week of January.




Across the Midwest and Great Lakes, lows are forecast to plunge into the -34C to -37C range (-30F to -35F), with pockets approaching -40C (-40F) in parts of Minnesota and Wisconsin by Saturday, Jan 24.

Several higher-resolution runs are colder still.

In Grand Rapids, some projections dip near -35C (-31F), which would obliterate the city’s all-time cold record by roughly 4C.

The air mass descending out of the Canadian Arctic, with reinforcement from a very snowy Siberia, is close to the coldest physically possible for America.

A continental-scale Arctic air mass is now surging south out of Canada and will engulf much of the United States through the end of the week, locking large portions of the country into one of the most severe cold outbreaks of recent decades.

A dense, shallow Arctic dome is dropping into the Midwest and Great Lakes before plunging into Texas and the Southeast.

Temperatures across wide swaths of the country will fall 20C to 30C (36F to 54F) below late-January norms.

In the northern Plains and Upper Midwest, surface readings near -30C (-22F) are likely, with -40C (-40F) air pressing south out of Canada. Wind chills will crash into the -40F to -50F range across multiple states.

On the back of this forecast, U.S. Natural Gas prices have surged a whopping 49% (since Monday).

The atmospheric setup is classic and dangerous.

A powerful tropospheric polar vortex lobe is digging south, marked by exceptionally low mid-level thickness values more typical of deep Siberian winter. At the surface, a massive Arctic high exceeding 1050 mb is anchoring the cold in place, allowing it to pool near the ground and resist erosion. Once established, this air mass does not move quickly.

The real problem begins where this cold collides with moisture.

The ECMWF continues to roll out a relentless Arctic pattern for the United States, with subzero temperatures forecast for about 102 million people, just over 30% of the U.S. population, into early next week.

The model now shows a parade of major winter events: a wallop this weekend, then a second Arctic blast peaking Jan 29-31, followed by an even stronger third wave around Feb 2-4. This is not a brief cold shot. It is sustained Arctic influence.

Latest ECMWF guidance points to roughly 250 million Americans affected by a massive winter storm tied to a sprawling Canadian cold pool. The event sweeps Texas late Friday (Jan 23) with freezing rain, then a rapid flash freeze as Arctic air crashes south.

Ice accretion extends through Little Rock and along Interstate 40 into the Carolinas, while snowfall totals explode to the north across the Ohio River Valley, the Mid-Atlantic including Washington D.C., and onward through New York City into New England.

At the first storm’s peak on Sunday, roughly 55% of the country is expected to experience snow, sleet, or freezing rain, which would rank among the largest winter weather events most Americans will experience in their lifetimes.

A major polar vortex disruption has plunged much of the Northern Hemisphere into deep winter, with the US enduring one of the coldest/snowiest Januaries in decades.
Hemisphere-wide cold.

Across the U.S., record cold has now settled in behind a powerful winter storm, locking much of the central and eastern states into prolonged, dangerous conditions.

The NWS has issued widespread extreme cold alerts stretching from the Plains through the South and into the East, with dozens of cold records already falling and hundreds more at risk through early week.

Arctic air remains entrenched across the United States, delivering widespread cold, heavy snow, and mounting impacts.

As of Monday evening, the Lower 48 average temperature was 27.8F, which is 10.4F below normal, with about 206 million Americans below freezing.

That cold intensifies again this weekend.

Come Tuesday, national average lows tank to 13.6F (map below), with more than 260 million below freezing overnight and roughly 140 million failing to thaw during the day.

From Jan 23 to 26, almost 1,000 reports of ice accumulations and/or ice storm damage have been received by NWS offices from New Mexico to New England:

Snow totals continue to climb, too.

Preliminary reports already exceed 20 inches in parts of New England, New York, and Pennsylvania, with Boston adding again to seasonal totals. Several stations are approaching daily and multi-day snowfall records, with final tallies still being compiled.

Below is a snapshot of U.S. snow cover on Jan 23 and then Jan 26 (NOHRSC). It shows 56% coverage of Lower 48 Monday AM, which is by far most widespread of the season.
Lake-effect snow remains active downwind of the Great Lakes and will persist until surface waters freeze.

Anchorage, Alaska was hammered by another major snowstorm Jan 27, pushing the city to its snowiest January on record in books dating back to 1952.

7+ inches fell in less than 24 hours, driving January’s total to nearly 40 inches and breaking the previous monthly record of 34.4 inches set in 2000. Tuesday’s snow also smashed the daily January record, surpassing the old mark of 3.6 inches from 1992.

Police reported more than 100 crashes and nearly as many additional vehicles in distress by late afternoon. Parts of the Glenn Highway were closed for hours as vehicles slid off the roadway and traffic was diverted through Eagle River.

The National Weather Service upgraded its forecast from a winter weather advisory to a winter storm warning as totals surged well-beyond expectations, with up to a foot reported in parts of the Anchorage area by Tuesday night.

Forecasters noted that the system proved difficult for models to resolve, contributing to the initial underestimation.

A deep Arctic surge delivered one of the coldest February nights Florida has seen in decades, pushing freezing air all the way to the subtropics and setting or tying a long list of monthly records across the state.

In Florida, temperatures fell as low as 18F (-7.8C), an extreme reading for the peninsula. Along the central and east coast, multiple long-standing February records were broken or tied.

Sanford and Leesburg each dropped to 23F (-5C), tying their coldest February lows ever recorded. Daytona Beach fell to 23F (-5C), its coldest February temperature in weather books dating back to 1923. Melbourne fell to 24F (-4.4C), also establishing a new monthly record in books back to 1937.

Cold pushed south with little moderation.

Vero Beach posted 26F (-3.3C), West Palm Beach dropped to 30F (-1.1C), and Fort Pierce hit 23F (-5C), setting a new February low and coming within just 1F of its all-time record. Orlando fell to 24F (-4.4C), as did Lakeland — both among the coldest February readings on record.

Even South Florida was not spared.

Miami International Airport registered 35F (1.7C) — a reading just 3F shy of the city’s February record low, ranking as the fourth-coldest February temperature since records began in 1937 and the coldest February reading there since 1947.
