Planning Outlook
High pressure becomes established over Britain at the start of the new week, drifting toward Scandinavia by midweek. A weak front grazing past northwest Scotland on Tuesday brings low cloud and some possible dampness for a time here. Otherwise, very warm and particularly on western mountains often sunny. However, particularly in the mornings low cloud coming in off the North Sea will often envelop more eastern mountains from midweek. Fresh easterly breezes affecting England and Wales in the second half of the week, locally becoming very gusty. Lighter winds generally in Scotland.
