How windy? (On the summits)
Easterly 35 to 50mph, powerful gusts around high tops, passes and downslope to the west; may lessen SE'ly later.
Effect of the wind on you?
Challenging conditions, difficult mobility over higher tops, buffeting gusts knocking you off balance. Severe wind chill.

Snow or sleet for several hours
Snow on and off over higher terrain, mostly sleet or rain below 500m, may be briefly lower at first. May turn wetter higher up before fading into afternoon. Local rain or sleet showers may follow.
Cloud on the hills?
Fairly extensive, highest west
Covering most hills in the morning, lowest bases in east above 400-500m, mostly 600-700m further west with some breaks. Bases tending to rise into afternoon.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Overcast and dull, or murky in morning especially in east, poor visibility across hills. May improve a little afternoon.

0 or 1C, small change with height above 700m. Wind chill feeling like -12 to -15C.
Freezing Level
Close to freezing point on higher slopes, icy surfaces above 700m.
Planning Outlook
East or southeasterly winds prevail, persistent gales later this week, severe chill factor over the mountains. Freezing levels will vary, lowering widely again below 600m during Thursday, though staying higher in Wales; then less cold widely into the weekend, rising just above freezing point in Scotland toward 1000m or briefly higher. Colder air then likely returns from east next week. Further snowfalls mostly over eastern hills in Scotland, occasionally hills in England & Wales, mixed with rain here. Indications of less precipitation and lower wind speeds for periods during next week. Highest cloud breaks generally west & northwest Scotland.
