Planning Outlook
High pressure will dominate the weather pattern through into the start of November bringing settled conditions. Broadly dry for a week or so, but some areas of misty dampness and regular fog on low ground, whilst many hills would be in the clear above an inversion, particularly in Scotland next week. Overnight frost in glens will be common, plus some frost pockets for sheltered high terrain, whilst many summits will stay often just above freezing point. Light winds for several days into next week for Scotland, but stronger easterlies are likely for England and particularly Wales which would push cloud banks higher up here during the week ahead.
