Summary for all mountain areas

Southwest winds; gale force across Lakes/N Pennines/S Uplands and storm force over the Highlands. Extensive low cloud across the hills with patches of drizzle ahead of a cold front that will push southeast through the day bringing a period of heavier rain to all hills. Colder air into Scotland later with snow showers in west.

Headline for Peak District and Yorkshire Dales

Extensive hill fog, local breaks south/east. A little drizzle, steadier rain later.

How windy? (On the summits)

Southwesterly, 25 to 35mph; strongest across the Yorkshire Dales where perhaps locally 40mph for a time.

Effect of wind on you?

Generally arduous conditions, locally very gusty through passes and cols. Significant wind chill.

How Wet? (Precipitation and its impact)

Risk rain becoming heavy Yorks Dales

Patches of drizzle, mostly across the western Yorks Dales. Elsewhere, only rare spots of drizzle. Later in the afternoon, steadier rain will develop across all areas as a cold front moves down from the northwest.

Cloud on the hills?

Most persistent western Yorks Dales

Extensive hill fog across the hills above 400-600m, lowest bases western Yorks Dales. Some local breaks developing for a time across Peak District and perhaps the eastern Dales, before cold front arrives.

Chance of cloud free summits?

40%

Sunshine?
Air clarity (below cloud)

Glimpses of sun mostly eastern valleys. Visibility locally good for a time, but often murky on western hills, particularly in drizzle.

Temperature (at 600m)

And in the valleys

Reaching 11 to 15C, warmest eastern valleys. If rain develops from northwest, dropping several degrees.
