How windy? (On the summits)

East to southeasterly 20 to 30mph, gusty in places around higher tops, locally to some lower slopes in west.

Effect of the wind on you?

Varied, blustery on tops, affecting comfortable walking in exposure at times; considerable wind chill.

Rain and some hill snow

Risk of fairly persistent rain, falling as sleet or snow on higher terrain mostly above 600-700m. Smaller amounts westward.

Cloud on the hills?

Fairly extensive

Covering most higher terrain, above 500-600m, possibly lower some southeastern slopes. Higher bases toward western Cambrians.

Chance of cloud free summits?

20%

Sunshine and air clarity?

Largely overcast, dull, locally brighter toward west Wales. Hazy, poor visibility in rain/snow.

How Cold? (at 750m)

Around 0C. Wind chill feeling like -5 to -8C.

Freezing Level

Close to freezing above 500-600m, particularly eastern areas, but just above freezing on upper slopes further west.

Planning Outlook

Southeast then easterly winds will prevail during the week ahead, strong to gale force over many hills for sustained periods. From Monday into Tuesday onward, colder air temperature and lower freezing level again, leaving mountain terrain widely frozen from mid-elevations upward, or to lower slopes in eastern Scotland. Further snow will affect eastern mountains, with additional accumulations and drifting. Some periods of hill snow for England and Wales into midweek. Cold easterly patterns are expected to continue onward into mid February, though higher pressure to the north may see reduced precipitation amounts, always driest with highest cloud in west.
