East-southeasterly 15-20mph from dawn, rising during day to 25-30mph and increasingly gusty; stronger after dark.

Freezing Level
Above the summits. Local frost pockets in sheltered valleys around dawn.
Planning Outlook
High pressure persists into the start of the new week with light winds for much of Scotland, though an easterly wind will increase for England and Wales. The west and northwest Highlands most extensively dry with cloud breaks and sun. However, disappointing for other areas as 'gloomy' conditions predominate, with patches of light rain and extensive low cloud and fog. Into midweek, an area of low pressure will bring rain and wind in from the southwest but northern Scotland may escape most or all the rain. Late in the week, indications favour a switch to a colder northerly flow for a time in Scotland at least and brings scope for snow showers to northern mountains.
