Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.

Summary for all mountain areas
A blustery, gusty morning in northern England and Scotland, gales for a time in northwest Scotland, tending to ease. Patchy rain from central Scotland down the spine of the Pennines eases into drizzle over the high tops, drizzle in east Wales too with extensive hill fog in these areas. Best of breaks west Wales and NW Highlands.
Headline for Southern Uplands
Blustery, gradually easing; rain, drizzle, and hill fog
How windy? (On the summits)
Southeasterly 30-35mph from dawn with some stronger gusts over the tops of Galloway. Gradually easing to 20-25mph by dusk.
Effect of the wind on you?
Blustery and gusty winds with sudden, strong gusts over the tops early in the day. Conditions improving with time, though winds likely remain uncomfortable in exposure.

Patches of rain for most areas throughout the day. Patches will merge into broader areas of rain at times in Galloway, particularly on southern slopes and near the M74.
Cloud on the hills?
Fairly extensive
Fairly extensive banks of cloud covering the hills through the day. Lowest bases across the Cheviots up to the Pentlands and also hills nearest the Solway; best chance of breaks on slopes north of Merrick.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Overcast. Visibility perhaps good at times below the cloud, but hazy east and poor visibility in rain.
How Cold? (at 750m)
3 or 4C, highest temperatures in the east.

Planning Outlook
Cloud and patchy rain lingers for a few more days early next week, then a slow change to drier and chiller weather into the Christmas period as high pressure builds to the north. Easterly winds will be dominant, the strongest winds in England and Wales. Cloud may be fairly sheet-like in the east sometimes, though variably more extensive or broken. The coldest air will reach England and Wales on the easterly wind with freezing levels reaching as low as 400-600m in Wales, staying slightly warmer in northern Scotland with freezing levels nearer the high summits for a time under the core of high pressure.
