Planning Outlook

Pressure builds across Britain to start the week, leaving just isolated showers. During Tuesday, a front moves into western Scotland - the legacy of this likely to bring a dull, damp day on Wednesday for some. Uncertainty later in the week: high pressure toward north/east, whilst areas of showers may move around slowly. Temperatures recovering gradually. Please be aware of currently different restrictions regarding Covid-19 across Scotland, England & Wales. Refer to local guidance or instructions from the National Parks and outdoor bodies, and please respect local communities in areas which are gradually reopening.
