Planning Outlook
Low pressure to the northwest maintains a humid southwesterly wind mid-late this week, with fronts situated near northwestern coasts - often extensive low cloud here with some drizzly rain. Drier with sun and broken cloud in east and southern Scotland. High pressure expanding over England and Wales brings more sunshine and draws in increasingly very warm air again in the later part of this week, higher temperatures extending into Scotland with time; some mist may continue to affect coasts in the west.
