Planning Outlook
A humid southwesterly wind during midweek produces extensive low cloud across west and northwest Scotland with some drizzly rain. Drier with sun and broken cloud in eastern Scotland, improving in southern areas. 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 and more sunshine extending into Scotland with time. A fine and very warm weekend in prospect, low risk of thundery showers forming toward the west. Cooler with a greater risk of showers early next week.
