Planning Outlook
High pressure drifts slowly east, whilst low pressure over the Atlantic encroaches nearer in the early part of the new week. Southeasterly winds increasing Sunday-Monday, soonest for western regions, becoming much windier by Monday in west, then more widely with time. Areas of rain and showery bursts increasingly widespread as the week progresses as low pressure then rotates slowly over Britain - day-to-day detail becomes very uncertain. Warmer and more humid for a time, then cooler later in week.
