What the phrase means
A blizzard of the month is not an official classification but a descriptive label sometimes used by forecasters, journalists, and weather communicators to highlight a notable winter storm in a given month. The phrase borrows from standard blizzard criteria—sustained winds or frequent gusts of 35 mph (56 km/h) or more, and considerable falling and/or blowing snow that reduces visibility to a quarter mile (400 m) or less for at least three hours—while emphasizing the event’s timing within a calendar or financial month. It is typically employed to distinguish a particularly severe storm from routine winter weather and to underscore its potential impacts on transportation, power, and daily life.
Official blizzard criteria and how they apply
The National Weather Service (NWS) and equivalent meteorological agencies use consistent, evidence-based thresholds to define a blizzard, regardless of the month. These criteria focus on wind and visibility and do not include temperature, which is often misunderstood. Understanding these standards helps clarify when the phrase blizzard of the month is appropriate and when it may be more figurative or promotional language.
Core elements of a blizzard
- Sustained winds or frequent gusts of 35 mph (56 km/h) or greater.
- Ongoing snow, either falling or blowing, that keeps visibility at or below a quarter mile (400 m).
- These conditions must persist for at least three consecutive hours.
Temperature is not part of the official definition, although dangerously low wind chills often accompany blizzards. The phrase blizzard of the month is generally reserved for events that meet these standards while standing out within a monthly timeline, whether due to intensity, duration, or impacts.
How the term is used by forecasters and communicators
Meteorologists typically avoid informal superlatives in official products, but communicators, media outlets, and local forecasters sometimes use expressions like blizzard of the month to signal a high-impact event within a specific period. This framing can help audiences compare storms within a seasonal or monthly context and understand relative significance. It is most often employed when a storm is historic for a particular month rather than for an entire season.
When the label is applied
- A storm that sets or approaches records for intensity or impact in a given month.
- An event with exceptional travel disruptions, power outages, or safety concerns during a specific timeframe.
- A high-profile case that underscores the need for preparedness and timely warnings.
Because the phrase is not a technical classification, its use can vary. Responsible communicators clarify the actual conditions—wind, visibility, duration—and avoid relying solely on the catchy label.
Impacts and what to expect during a blizzard
Whether labeled a blizzard of the month or simply a major winter storm, storms that meet blizzard criteria can create severe and widespread effects. Visibility near zero, difficult or impossible travel, and extended power outages are common. Transportation networks, including highways, public transit, and air service, may shut down or operate at reduced capacity for hours or days. It is crucial to follow official guidance, avoid unnecessary travel, and be prepared to stay indoors for an extended period if conditions deteriorate.
Preparedness and safety basics
- Maintain a winter emergency kit with water, nonperishable food, medications, flashlights, batteries, and a charged communication device.
- Keep vehicle fuel tanks near full and avoid travel during the height of the storm.
- Stay informed via reliable sources such as the National Weather Service, local emergency management, and trusted media outlets.
- Check on neighbors, especially older adults and those with access or functional needs, provided it can be done safely.
A brief history of blizzard terminology and notable examples
The use of the month-based framing likely emerged from public and media shorthand for powerful winter storms that occur outside the traditional peak season. While historic blizzards are often referenced by year or region, recent decades have seen increased attention to high-impact winter storms in less typical months. This trend reflects both better detection and communication and growing public interest in extreme weather events. The following table summarizes notable U.S. events frequently discussed in conversations about strong monthly storms, though many additional regional events meet similar criteria.
Notable U.S. blizzards in non-peak months (illustrative examples)
| Date or Period | Event | Why It Matters |
|---|---|---|
| March 1993 | Storm of the Century (March 1993) | Massive nor’easter that affected the entire Eastern U.S. with blizzard conditions in many areas, heavy coastal flooding, and significant snowfall well outside the traditional season. |
| April 2019 | Colorado Plains blizzard (April 2019) | A powerful spring blizzard in northeastern Colorado with near-zero visibility and heavy snowdrifts that closed highways and stranded vehicles, illustrating that severe blizzard conditions can occur well after winter’s official end. |
| November 2022 | Great Lakes late-season blizzard (November 2022) | A rapidly intensifying cyclone produced blizzard conditions along Lake Erie and southern Lake Huron in mid-November, an uncommon but increasingly observed setup tied to lake-effect and cyclonic dynamics. |
| January 2022 | Western U.S. atmospheric river–blizzard complex (January 2022, Sierra Nevada) | Heavy snowfall combined with hurricane-force winds created blizzard conditions in the mountains, highlighting the intersection of atmospheric rivers and winter storm dynamics outside the heart of winter. |
Events like these demonstrate that blizzard conditions can occur across a broader window than the core winter months and that preparedness, warnings, and impacts matter more than the calendar label.
Common misconceptions and clarifying points
Because the phrase blizzard of the month is informal, it can encourage exaggerated interpretations. Below are common misunderstandings paired with clarified, evidence-based points.
Myth versus fact
| Myth | Fact | Source Type |
|---|---|---|
| Blizzard implies a specific temperature, such as below zero. | Temperature is not part of the official blizzard definition; wind and visibility are the defining factors. | National Weather Service |
| Any heavy snowstorm can be called a blizzard. | Heavy snow alone does not produce a blizzard; sustained winds or frequent gusts of 35 mph (56 km/h) and reduced visibility of a quarter mile or less for at least three hours are required. | National Weather Service |
| Blizzards only happen in deep winter. | Blizzard conditions can occur when temperature contrasts and dynamics align, such as during spring nor’easters or intense lake-effect events. | Meteorological agency statements and case studies |
Understanding the actual criteria helps the public make better decisions and reduces confusion when media or social posts use dramatic labels without explaining the underlying conditions.
Conclusion
The term blizzard of the month is a useful, though informal, way to highlight a high-impact winter storm in a specific calendar month. It draws attention to serious hazards—low visibility, strong winds, and travel disruption—without changing the scientific criteria that define a blizzard. By focusing on verified conditions and preparedness, communicators and the public can use such labels responsibly while maintaining clarity about what the storm truly entails and how to stay safe.
