snøbyge

A snøbyge, a Norwegian term, refers to a localized and often brief snowfall. It is characterized by its sudden onset and temporary nature, distinguishing it from prolonged snow events. These snow showers can occur when unstable air masses move over a colder surface, leading to convection and the formation of cumulonimbus or cumulus clouds that produce precipitation.

The intensity of a snøbyge can vary, ranging from light flurries to moderate snowfall, and they are typically accompanied by gusty winds. Visibility can be significantly reduced during a snøbyge, creating hazardous driving conditions. These events are common in mountainous regions and coastal areas, particularly during colder months.

While a snøbyge is a type of snowfall, its defining characteristic is its localized and intermittent nature. It can pass over an area quickly, leaving behind a temporary blanket of snow that may melt soon after the shower ends. Unlike a steady snowfall that covers a wide area for an extended period, a snøbyge is more like a passing squall of snow. The term emphasizes the sudden, almost impulsive, nature of the snow event.
