What is needed for snow?

In the UK conditions are often marginal for snow, so a number of factors need to align. Just being cold isn't always enough!

For snow to fall and settle you generally need three key ingredients:

1. Cold Air Aloft: The air high up in the atmosphere must be cold enough. Temperatures there need to be at or below freezing (0°C). If it's warmer aloft precipitation will fall as rain even if it's freezing at the ground. A cold air mass is most likely when winds blow from a northerly or easterly direction.

2. Cold Air at the Surface: Temperatures at ground level generally need to be 2°C or lower. However, it can sometimes snow at higher temperatures, particularly if the air is very dry.

3. Enough Moisture: A cold snap on its own isn't enough; there must be moisture in the air to form clouds and precipitation. This is why a cold northerly wind often brings dry weather to southern Britain, while snow showers develop in the north and near coasts where the wind picks up moisture.

This combination is why snow in the UK is most common in the north and over higher ground where these conditions are met more often.
