Summary for all mountain areas

Windy most mountain areas, although a gradual drop across hills in N England and S Scotland. Snow showers, to lower slopes across Scottish Highlands, elsewhere, rain on and off, but snow higher slopes. Borders and perhaps west to Galloway dry.

Headline for Snowdonia National Park

Upland gales. Snow, most persistent afternoon.

How windy? (On the summits)

Westerly, 40 to 50mph, there may be a slight lull early afternoon, then strengthening to 50-60mph toward dusk.

Effect of wind on you?

Widespread considerable buffeting; at times mobility difficult on higher areas. Severe wind chill.

How Wet?

Snow intermittently

Pulses of snow, or below 500m rain, through the day. Generally changing from showers to more constant precipitation in afternoon, when particularly western mountains the snow may set in for 2 to 4 hours giving whiteout.

Cloud on the hills?

Soon becoming extensive

Some higher areas may intermittently clear early morning, although shafts of cloud to 600m during precipitation. Gradually, higher areas extensively shrouded as cloud envelops the region, lowering to lower slopes near coast.

Chance of cloud free summits?

20% morning; less than 10% afternoon.

Sunshine and air clarity?

Sunshine unlikely. The air very clear, but becoming increasingly hazy, and visibility appalling where in cloud and also snow.

How Cold? (at 900m)

-3C rising slowly toward 0C late afternoon from southwest; feeling as cold as minus 19 Celsius where exposed to strongest wind.

Freezing Level

650m; lifting toward 1000m toward dusk.

Planning Outlook

All mountain areas of Britain from Thursday 2nd April 2015

On Thursday the strongest winds will ease markedly, particularly for Scotland where it will be mainly dry. Precipitation will still come and go for Wales. By Good Friday, areas of early rain and snow will slowly break up for many areas. Easter weekend will bring much quieter weather, with light winds and dry conditions; some uncertainty by Monday as weak fronts approach western Scotland. Although the freezing level will rise above most summits, the Scottish Highlands in particular will broadly remain in 'winter' condition through the weekend, with at least part frozen terrain and recent snow on higher areas, which will melt only slowly.
