Summary for all mountain areas

Another fine and dry day across many areas with extensive haze sunshine through a canopy of high level cloud. However, a front will introduce fresher, cloudier conditions with some drizzly rain to the W/NW Highlands with very low cloud increasingly enveloping western hills. Risk of drizzly rain more widely later.

Headline for The Northwest Highlands

Patchy drizzly rain/low cloud edging inland. Often clear in the east.

How windy? (On the Munros)

Southwesterly 20-30mph, strongest in the morning when locally 35mph in west. Easing to 10-15mph in south late on.

Effect of wind on you?

May impede walking at times across higher areas with marked wind chill.

How Wet? (Precipitation and its impact)

Patchy drizzly rain edging inland

Patches of rain and drizzle will edge in from the west through the day; mainly confined to western coastal hills at first, but becoming somewhat more extensive in the afternoon.

Cloud on the hills?

Low cloud slowly edging inland.

Western hills: Low cloud edging inland to envelop hills in fog above 400-700m; but down to 200-400m across western coastal hills. Elsewhere: Often clear, threat of some patchy low cloud for a time in rain.

Chance of cloud free Munros?

30% in the west, 80% in the east.

Air clarity (below cloud)

Some weak sun in the east through dense high level cloud at first. Otherwise overcast. Becoming murky in the west, especially toward the coast. Visibility mostly good in east, but slight haze.

How Cold? (at 900m)

7 to 9C, but lowering to 4 or 5C toward west coast through day.

Planning Outlook

All mountain areas of Britain from Sunday 21st April 2019

SE winds return for the start of next week bringing largely dry, warm and fairly sunny conditions to many once again; most widely in the northwest where it will become very warm in the glens/valleys. However, increasingly through the week the atmosphere will become more unstable bringing an increasing risk of heavy showers. Initially these will be mainly confined to Wales, but from midweek increasingly these heavy, locally thundery, showers will spread north N England and Scotland introducing fresher conditions. By next weekend, a cooler, cyclonic southwesterly pattern is likely to become established. The ground remains very dry underfoot - beware of grass fires.
