How windy? (On the summits)
South-easterly 15 to 25mph, but perhaps lifting to 30mph east Wales and into mid Wales.
Effect of the wind on you?
Increasingly blustery across hills in east Wales down to mid Wales. Otherwise, mostly small.
How Wet?
Mostly dry, risk showery bursts later.
Any spots of rain, or snow flurries tops, from dawn fading, to leave dry conditions mostly. Later, most likely after dusk, risk showery rain moving in from the south.
Cloud on the hills?
Extensive, lowest east Wales.
Extensive low cloud across the hills, widely to mid slopes across east Wales, but more generally around 800-1000m toward the west coast.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Very little if any sun. General haze, best visibility near west coast.
How Cold? (at 900m)
1C, lifting to plus 3C
Freezing Level
1000m, but soon above highest summits.
Planning Outlook
Cold east or southeasterly winds prevail, but less cold widely over the weekend as freezing level lifts somewhat from the south, rising just above freezing point in Scotland toward 1000m. Colder air then likely returns from east next week. Further snowfalls mostly over eastern hills in Scotland, occasionally hills in England & Wales, mixed with rain here. Indications of less precipitation and lower wind speeds for periods during next week. Highest cloud breaks west & northwest Scotland, where terrain will be very dry toward west coast.
