Can You Use Clouds to Predict Snowfall Accumulation?

Reading Clouds for Snowfall Prediction

When it comes to predicting snowfall accumulation, observing clouds is an essential skill for survivalists and outdoor enthusiasts. Cumulus clouds, often referred to as “fair-weather clouds,” typically indicate stable atmospheric conditions, which are less likely to produce significant snowfall. However, if these clouds are towering and dense, they can develop into cumulonimbus clouds that can produce heavy snowfall.

Identifying Storm Indicators

Cirrus clouds, on the other hand, can be a sign of an approaching storm. These high-level clouds often indicate a change in the weather, and their presence can be a warning sign for snowfall. If cirrus clouds are seen at low levels, it can indicate a stronger storm system is approaching, increasing the likelihood of significant snowfall. A general rule of thumb is to look for cirrus clouds below 20,000 feet (6,000 meters) to predict snowfall accumulation.

Fronts and Snowfall Accumulation

Fronts, whether cold or warm, can be a significant indicator of snowfall accumulation. A cold front, for example, can bring cold air into an area, leading to snowfall. A warm front, on the other hand, can produce light to moderate snowfall. By observing the type of front and its proximity to your location, you can make a more accurate prediction of snowfall accumulation. For example, if a cold front is approaching within 12 hours, you can expect significant snowfall accumulation.
