How windy? (On the Munros)

West-southwesterly, often 30mph, to 35mph southern Munros, and tending to strengthen widely, to 40mph Arran and southern Loch Lomond NP in gusts, more sustained during afternoon.

Effect of the wind on you?

How Wet?

Drizzly rain becomes steady rain for several hours

Rain drifts from the west much of the day, generally light in nature early in the day with dry windows inland, but also often drizzly on the high tops in cloud.

Planning Outlook

Southwesterly winds will bring rain to most places early this week, some more prolonged heavier falls for western Scotland into Tuesday, accompanied by gales over high terrain, severe on Scottish tops, but rather humid for all, warm for England and Wales. Cooler air toward northwest Scotland moves across all of Scotland by Wednesday. Showery rain through mid-late week, some heavy and possibly thundery bursts, mainly Scotland. Likely drier for Wales and southern Pennines. Remaining very uncertain detail toward next weekend and early the following week, but indications favour a broad zone of low pressure bringing areas of rain and heavy showers through early August.
