The Worst Blizzards of All Time

Blizzards across the eastern two-thirds of the United States have steadily increased in frequency over the last century. Due to accelerating changes to the climate, including rising ocean surface temperatures (which leads to more moisture in the air) and reduction in Arctic sea ice (which can affect the jet stream), as well as natural variability, the increase in severe winter storms, especially in the eastern U.S., is expected to continue.

If there was any reminder of how disruptive winter storms can be it was the storm that snarled traffic along Route 95 in Virginia for a day the first week in January with motorists stuck in their cars for 24 hours or longer. And that wasn’t even considered a major snow event. So you can imagine what a really bad blizzard would cause.

Unlike hurricanes and earthquakes, there is no widely used scale or index for assessing the impact of snowstorms. In recent years, however, the meteorological community has made several successful attempts to establish a standard for measuring the impact of extreme snow events that can be used to compare snowstorms over time. (These are the most powerful hurricanes of all time.)

The Regional Snowfall Index, introduced in 2014, ranks a snowstorm impact on a scale of 1 to 5 using data on a storm’s area of snowfall, the amount of snowfall, and the population affected. The RSI has since been used to retroactively classify nearly 600 snowstorms that occurred between 1900 and 2013.

To determine the worst blizzards of all time, 24/7 Wall St. ranked snowstorms based on their Regional Snowfall Index values, published by the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information.

We included the 25 snowstorms designated as Category 5 since 1900. Data on duration, region, affected area, and affected population also came from the NOAA. 24/7 Wall St. combined data on affected area and population for Category 5 storms that spanned multiple regions, considering it one event. Storm names, as well as measures of snowfall in the affected areas, came from various news and media sources. (These are the places with the biggest snowfalls in history in every state.)

25. The Chicago Blizzard of 1967
> RSI score: 18.13
> Duration: Jan 25th – Jan 29th
> Region: Ohio Valley
> Affected area: 286,503 square miles
> Population affected: 46.1 million
> Notable snowfall: 23 inches (Chicago, Illinois)

As the snow began to fall on Jan. 26th, most Chicagoans were able to make it to school and work. The commute home, however, was a disaster. As eight inches of snow blanketed the city by noon, transportation systems shut down and commuters were left stranded in their cars, or their offices or in a hotel, if they could find a room. By the 28th, the city had dug itself out from the blizzard, but more than 60 people died in what was termed the most disruptive event in the city’s history since the Great Chicago Fire of 1871.

24. The Great Atlanta Blizzard
> RSI score: 18.14
> Duration: Jan 21st, 1940 – Jan 24th, 1940
> Region: Southeast
> Affected area: 214,946 square miles
> Population affected: 35.6 million
> Notable snowfall: 21.6 inches (Richmond, Virginia)

Although Atlanta has been known to weather an occasional snowstorm, the city was hit with a paralyzing blizzard in January of 1940. Instead of the typical two to four inches of snow dumped on the city by an average Atlanta storm, the Great Atlanta Blizzard covered the Southern capital with more than 10 inches of the white stuff, closing schools and transportation and downing power lines. But in Virginia, Farmville was hit even worse by the same storm – the town 55 miles southwest of Richmond was buried in 24 inches of snow.

23. The Blizzard of 1978
> RSI score: 18.42
> Duration: Feb 4th – Feb 8th
> Region: Northeast
> Affected area: 174,950 square miles
> Population affected: 58.9 million
> Notable snowfall: 55 inches (Lincoln, Rhode Island)

The Blizzard of 1978 stretched from New England to New York, New Jersey, and Pennsylvania. Snow totals ranged from 27 inches in Boston to 16 inches in Philadelphia. About 100 people died,10,000 sought emergency shelter, and more than 2,000 homes were destroyed or severely damaged, including many along the New England and Long Island coastline. All told, the storm caused $520 million in damages, which equates to almost $2.2 billion in 2021 dollars.

22. The Knickerbocker Storm
> RSI score: 18.53
> Duration: Jan 26th, 1922 – Jan 30th, 1922
> Region: Southeast
> Affected area: 150,041 square miles
> Population affected: 30.1 million
> Notable snowfall: 28 inches (Washington, D.C.)

The Knickerbocker Storm got its name from a tragic event related to the blizzard. So much snow fell on the Knickerbocker Theatre in Washington, D.C. that the roof collapsed, killing 98 people and injuring 133 at about 9 p.m. on Jan. 28. The nation’s capital took the brunt of the accumulation with a blanket of 28 inches, but Maryland and Virginia were also covered with heavy snow.

> Affected area: 261,324 square miles
> Population affected: 10.5 million
> Notable snowfall: N/A

Not known for significant snowstorms, northwestern Oklahoma was inundated with 36 inches in the town of Buffalo, creating 20-foot high snow drifts. Yet nearby cities in the Oklahoma Panhandle received light snow of only two to three inches. Thousands of head of livestock were lost in the storm, but the precipitation gave the parched area some relief.

> Population affected: 2.4 million
> Notable snowfall: 28.3 inches (Denver, Colorado)

The Blizzard of 1920 buried parts of northern Colorado under two to three feet of snow. But as the Berthoud Bulletin described the event, the snow started to fall early one Saturday morning and continued until Sunday night. By Monday, the dig-out had started and life resumed as normal soon afterwards.

> Region: South
> Affected area: 380,488 square miles
> Population affected: 31.2 million
> Notable snowfall: 26 inches (Hillsboro, Texas)

December 1929 in northern Texas started warmly with temperatures in the 60s and 70s. Yet the weather took a severe turn on December 17, when temperatures plunged to a frigid 40º. Although the height of the storm lasted only 24 hours, some cities recorded more than 20 inches of snow. The highest total was in Hillsboro, where 26 inches fell – a record for a 24-hour snowfall in the Lone Star State that still stands today.

A blizzard is never welcome any time of year, but when it occurs around a busy holiday travel season its effects are even worse. In late November of 1993, a storm swept across the Upper Midwest, dumping massive amounts of snow in South Dakota and Minnesota. Westport, South Dakota weathered the highest total at 32 inches.

The Regional Snowfall Index (RSI), a NOAA-developed system to assess the impact of snowstorms in different regions of the U.S., ranked this blizzard as a Category 5, or extreme, event — one of only 26 storms so classified since 1900. Arkansas bore the brunt of the storm, with Mount Vernon accumulating 30 inches of snow and six other communities getting at least two feet. The state capital, Little Rock, got off comparatively lightly with 11.6 inches of snow and 1.5 inches of sleet.

> Population affected: 23.6 million
> Notable snowfall: 12.9 inches (Dayton, Ohio)

The Ohio Valley and Great Lakes region endured one its worst winter storms in late January of 1978. In addition to massive snow totals, the storm whipped up near-hurricane strength winds, earning the event its “White Hurricane” moniker. Ohio bore the brunt of the bad weather, with 51 people dying in that state. But across the area businesses, schools, and transportation were closed for days.
