Northeasterly mostly between 15 and 25mph although locally near and west of major ridges and cols 30mph, the strongest wind not necessarily on higher slopes.
Mostly fairly small.
Little or no rain
Largely or completely dry although risk that remnants of thunderstorms may give a few bursts of rain here and there and possibly still isolated thunder.
Extensive, before clearing many tops
Fog will shroud the hills most of morning from lowest slopes up eastern dales and above 400 to 550m above western dales. However, the base will lift and into the afternoon, most, perhaps all summits will clear.
30%
Ranging from dull and misty eastern hills, at least in morning to increasingly sunny with good visibility although a haze.
13C.
19 to perhaps 23C in western dales in the afternoon.

East or northeasterly 15 to locally 30mph - strongest winds may extend to some lower slopes.
Fairly small - although sudden buffeting in gusts some lower slopes.
Little or no rain
Threat of pockets of rain, locally heavy still drifting about and of well scattered thunderstorms in the afternoon.
Extensive - may persist all day
Blanket fog coming in off the North Sea may well shroud the hills from lower slopes up, particularly morning, although highest tops may be above the cloud. The fog patchy or by late morning perhaps clearing altogether western dales.
20%
Dull and misty, although cloud may break to give patchwork of sunshine western dales. Hazy.
12C.
16C eastern dales to 20 to 22C west in afternoon.
Remaining warm and particularly England and Wales 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.
