However, with squalls, conditions can vary greatly and it is common to see “changes from clear skies to heavy snow within just a few kilometres.”

Meteorologists are warning motorists of the potential for near-zero visibility at times as well as for snow-covered and icy roads.

In London, the forecast is calling for a high of -9 C on Monday with an overnight low of -15 C. Snowfall of 10 to 20 centimetres is expected overnight with another two centimetres forecast for Tuesday morning, which is expected to have a high of -6 C accompanied by scattered flurries.
