Summary for all mountain areas
Many mountains dry; warm sunshine in the west. Low risk of isolated thundery showers forming. Greater threat of thunderstorms mid & south Wales. Fog persists in eastern Scotland and England from low levels upward; just some highest tops above this layer.
Headline for Yorkshire Dales and North Pennines
Fog slow to clear eastern Pennines. Locally gusty wind.
How windy? (On the summits)
East or northeasterly 15 to locally 30mph - strongest winds may extend to some lower slopes.
Effect of the wind on you?
Fairly small - although sudden buffeting in gusts some lower slopes.
How Wet?
Little or no rain
Patches fine drizzle mainly morning N Pennines.
Cloud on the hills?
Extensive fog, most persistent east, clearing west.
Blanket fog from the North Sea continues to shroud many hills from lower slopes up, particularly morning and in east, although highest tops may be just above the cloud. Likely to persist most or all day in eastern areas, thinning only slowly, but further west the fog patchy or by late morning onward clearing altogether.
Chance of cloud free summits?
20% rising to 70% western Dales.
Sunshine and air clarity?
Dull and misty, although cloud may break to give patchwork of sunshine western dales. Hazy.
How Cold? (at 700m)
As high as 16C westernmost Dales if cloud thins, but only 11C where in persistent fog eastern N Pennines.
And in the valleys
15 to 17C where low cloud persists eastern dales, up to 20 to 22C western Dales in afternoon.

How windy? (On the summits)
Easterly; speeds varied, typically 20mph or less, but risk of local gusts to 30mph.
Effect of the wind on you?
Generally small, albeit locally gusty both higher and lower slopes (particularly passes and cols and west of higher tops N Pennines).
How Wet?
Rain very unlikely
Cloud on the hills?
May persist, particularly toward east
Confidence low in the extent that a blanket of very low cloud coming in off N Sea will break. It could persist most or all day above 300m eastern dales and 450m west, although it may break up from west during the day.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Hazy sunshine may come through at times, most likely western dales. Misty or foggy widely lower slopes at first. This thinning or clearing but remaining hazy.
How Cold? (at 700m)
16C, although 13C where in cloud.
And in the valleys
18 to 23C in afternoon, lowest where dull eastern dales.

How windy? (On the summits)
East or northeasterly, 15 to 20mph, but locally may be gusty to 30mph near/west of major ridges and summits.
Effect of the wind on you?
Fairly small, but local gusty conditions possible, in places to low levels.
How Wet?
Rain unlikely
Small risk of rain encroaching from the south late in the day.
Cloud on the hills?
Clearing most areas
Fog covering many eastern Pennine areas in the morning, where may be slow to thin. Otherwise, early patches of low cloud soon breaking up, soonest western Dales.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Patches of sun, breaking through mostly in west. Misty or hazy some areas in morning, visibility improving, may become excellent.
How Cold? (at 700m)
9C where in cloud, otherwise lifting to 13C, or locally warmer toward western dales.
And in the valleys
12C or locally below from dawn, rising to 17 to 20C by afternoon.
Planning Outlook
Remaining warm and humid through the weekend, particularly in western regions, whilst eastern areas are cooler under North Sea air, which brings a risk of lingering fog banks. The Scottish Highlands stay extensively dry. Thundery rain mostly confined to Wales, although rain may expand back northwards into the Pennines by Sunday. Into next week, light winds and areas of slow-moving showers at first, then a gradual change is likely as windier conditions move in from the Atlantic, with belts of rain or showers.
