Summary for all mountain areas

Much of the Highlands sees a fine day with fairly light winds; a veil of high cloud tends to thicken, risk of some rain later. S Scotland & N England has more cloud, some rain. Heavier rain moves across Wales into Peak District, followed by showers on a strong southwesterly wind, quite humid.

Headline for Southern Uplands

Rain on and off, varied cloud, wind increasing.

How windy? (On the summits)

South-southwesterly 15-20mph, some variability, and in afternoon strengthening to southerly 25-30mph, strongest soonest in west; rising further into evening onward widely southwesterly 35-40mph.

Effect of the wind on you?

Fairly small, but comfort of walking at times affected, likely more strenuous later with buffeting gusts developing.

How Wet?

Intermittent rain, drier for a time

Areas of rain and drizzle in the morning, some steadier rain with local heavier moments. This may fade for a few hours, but risk of rain returning to more western areas, may become persistent again afternoon-evening.

Cloud on the hills?

Extensive, some variations, lowering again southwest

Blanket cloud from 500-600m up most of the day, regularly lowering around rain and widely lower when rain sets in for a few hours. Some breaks may form temporarily to higher slopes, mainly more northern areas. Dropping to lower elevations toward the Solway later.

Chance of cloud free summits?

20%

Sunshine and air clarity?

Overcast, dull on high terrain toward south and west with poor visibility all day. Some brighter skies toward the Lothians with good visibility when dry.

How Cold? (at 750m)

10C rising to 12 or 13C, staying elevated into night; becoming humid. Feeling like 2 to 4C in strongest wind.

Planning Outlook

A series of weather systems moves in from the Atlantic this week and next to bring spells of rain and showers, accompanied by frequently strong to gale force mountain winds. A window of better weather is likely this Saturday for Scotland and northern England, but further rain is expected to move into Wales, which then extends north by Saturday night and Sunday, possibly widely heavy rain and a risk of more powerful upland gales developing over Scotland into Sunday. Temperatures will vary, mildest toward the south, but some cooler air moves in from the north at times bringing higher Scottish tops close to freezing point.
