Forecast last updated on Tuesday 25th November 2014 at 1:04pm

Summary for all mountain areas

Light winds on the mountains. As warmer air (over colder very humid air near the ground), & over England, a front, extends north, fog will shroud most hills, in some areas from valleys up. However, these conditions will be patchy in W & N Scotland where some summits cloud free.

Headline for Snowdonia National Park

Light wind. Drizzly rain, almost blanket low cloud.

How windy? (On the summits)

Southeast or easterly, 10 to 15mph.

Intermittent rain and drizzle; will tend to clear from south through the day.

Cloud on the hills?

Extensive, very low east

Broadly, cloud shrouding the mountains across the region, on eastern areas from lower slopes upward. The base will tend to lift westwards, and here and there some higher areas may clear at least temporarily.

Chance of cloud free summits?

Almost nil most of region; 10% west

Sunshine and air clarity?

Sunshine unlikely. Very hazy or murky; areas of fog from just above valleys up.

How Cold? (at 900m)


Freezing Level

Above the summits; but risk slight frost in a few valleys after dawn.

Planning Outlook

All mountain areas of Britain from Thursday 27th November 2014

Low cloud & occasional rain into the weekend, particularly eastern hills. On higher Scottish tops, a little snow. A front is then likely to bring 'cleaner' (less murk & low cloud) air to Britain, together with rain, & then showers (mainly W Scotland). Looking well into December, inspection of charts from the main forecast centres, suggests lower summit temperatures, freezing level typically 1000m, but relatively low precipitation next week (eastern mountains most at threat). Beyond, a few forecasts indicate frequent gales and precipitation in southwesterlies, but most suggest little change in freezing level, gradual accumulation of precipitation (most eastern Scotland).
