A ridge of high pressure will give a fine day and soon little wind across most mountain areas. However, low cloud and occasional rain (snow higher areas) will persist much of Wales all day, and edge northeast into coastal Scotland through the evening.

Headline for Snowdonia National Park

Extensive low cloud: may lift for a few hours. A little rain.

West to northwesterly, post dawn up to 35mph mid-Wales, but soon easing from the north to typically 15mph.

Effect of wind on you?

Soon small

How Wet?

Patchy rain; perhaps snow higher tops

Rain and drizzle on and off (post dawn risk snow higher tops Snowdon range), mainly coastal mountains, but total rainfall small. It may be dry for several hours morning and middle of day Snowdon range and eastern areas elsewhere.

Cloud on the hills?

Extensive

Generally extensive low cloud base 300-500m western mountains and 500-700m well inland. But for several hours in morning and middle of day, the cloud may lift to or possibly temporairly above higher tops Snowdon range and eastern areas.

Chance of cloud free summits?

20%

Sunshine and air clarity?

Sunshine unlikely. Visibility mainly good at lower levels, but extensive fog on higher areas.

How Cold? (at 900m)

Planning Outlook

All mountain areas of Britain from Friday 3rd April 2015

A transition of weather pattern to high pressure will mean substantial fine weather with light wind throughout Easter Week. It will become warm. However, in the shorter term, low cloud on Friday will slowly lift, and overall a lot of cloud over the weekend. Snow will melt slowly by day, often refreezing overnight (particularly next week).
