Headline for Yorkshire Dales and North Pennines

Local gusty winds. Warm and humid. Chance isolated thunderstorms.

How windy? (On the summits)

Northeasterly mostly between 15 and 25mph although locally 30, or northern Pennines 35mph, the strongest wind not necessarily on higher slopes.

Effect of the wind on you?

Mostly fairly small. However, buffeting, sometimes sudden, some higher ridges, through cols and passes and in places on lower slopes.

How Wet?

Little or no rain

Largely or completely dry although pockets of fine drizzle where in cloud in morning.

Cloud on the hills?

Extensive, before clearing many tops

Banks of fog valleys and lower slopes up after dawn. Above more western dales, the cloud will fragment to small amounts by mid morning, but above eastern dales may well remain most or all day, particularly N Pennines - may well clear North Yorkshire.

Chance of cloud free summits?

30%

Sunshine and air clarity?

Ranging from dull and misty most of day N Pennines, and in morning Yorkshire Dales to be increasingly sunny elsewhere, although still hazy .

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.

Planning Outlook

Remaining warm and humid. However, thundery rain will become mostly confined to Wales, whilst the Scottish Highlands are extensively dry. Overall extensive sunshine, although banks of very low cloud, mainly more eastern mountains, including those in east Wales. A change to wetter and gradually less warm conditions across Britain is likely early next week.
