All About Snow

Extreme Snowfall

Extreme snowfall events have set remarkable records, showcasing the power of nature. Gary Arndt highlights the record for the most snowfall in a 24-hour period, which occurred in Silver Lake, Colorado, in 1921, with an astounding 76 inches of snow 1. Similarly, the Mount Baker ski area in Washington state recorded an incredible 1140 inches of snow over the 1998-1999 season 1. These extreme cases often occur in mountainous regions or near large bodies of water, where unique weather patterns contribute to such phenomena 2.

The record for snowfall in a 24 hours period was set in Silver Lake, Colorado on April 14 and 15th, 1921. A total of 76 inches, or 6.3ft or 1.9 meters of snow fell in 24 hours.

Weather Patterns

Meteorological factors play a crucial role in creating notable snowfall records. Gary Arndt explains that orographic snow, common on the Pacific coast, occurs when warm, moist air is pushed up a mountain range, cooling and precipitating as snow 1. The lake effect, particularly pronounced around the Great Lakes, also contributes to heavy snowfall by picking up moisture from the lakes and dropping it as snow when the air cools over land 2. These geographical and weather patterns are key to understanding how such extraordinary snowfalls occur.

Warm, moist air will collide into a mountain range where it will be pushed up the side of the mountain. Once the air goes up the mountain, it faces a drop in temperature, which causes the moist air to precipitate out as snow.
