How windy? (On the summits)
Southerly, strengthening rapidly overnight up to dawn, 45 to 60mph all day, gusts reaching up to 70mph high tops.
Effect of the wind on you?
Difficult walking conditions on higher terrain, powerful gusts knocking you off your feet, including downslope gusts on northern aspects. Marked wind chill despite mild air.
How Wet?
Rain and drizzle, heavier later
Several hours of constant rain from dawn, heavy west and south. This fading to patchy light rain and drizzle, but later likely prolonged heavier rain setting in again from the west, ongoing into evening.
Cloud on the hills?
Extensive, lowest south
Blanket low cloud across the hills, from lower slopes up in southern areas. Highest bases to 500-600m eastern mid Wales, a few odd higher breaks possible though ragged patches will cling to lower slopes.

Sunshine and air clarity?
Overcast and murky. Very poor visibility though occasional improvements during rain breaks towards mid-Wales.

How windy? (On the summits)
Southwesterly 25-30mph. Trending lighter as afternoon goes and may become variable in a lull - detail uncertain.
Effect of the wind on you?
Strenuous walking on exposed high terrain for several hours, then a trend towards fairly small effects.
How Wet?
Drizzly rain, easing
Drizzly rain, primarily over high tops and south/western aspects, this tending to ease as the day goes. Rain may be heavier and widespread near dawn.
Cloud on the hills?
Extensive, improving, best mid-Wales
Fairly extensive at daybreak. Bases soon begin lifting to near or above 600m on northern and eastern slopes, some local breaks to tops may form on the Black Mountains. Fog likely remains extensive on high southern and western slopes.
Chance of cloud free summits?
30%
Sunshine and air clarity?
The day starts overcast with mostly poor visibility. Bright or sunny breaks will occur mid-Wales with improving visibility here.
How Cold? (at 750m)
9C. Feeling just above freezing in strongest winds early in the day.
Freezing Level
Above the summits.
Planning Outlook
Periods of heavy rain for many over several day; further flooding for Wales, the Lakes and southwest Scotland. Cooler than recently in Scotland with freezing levels lowering to most high terrain, snow showers falling on high terrain from the north; remaining generally mild England and Wales by day and night. Later in the week and into the weekend, high pressure draws colder air into Scotland and progressively further south into England and Wales over the weekend. Strong easterlies are likely over England and Wales and conditions will be largely dry with some clear hills and sunny bursts; overnight frosts likely widespread in Scotland. The weather regime the following week is uncertain but first indications suggest more unsettled weather.
