Summary for all mountain areas
The Pennines and east Scotland begin with weak sun through high cloud and largely dry. Western areas start cloudier with patchy rain, then Storm Boelo draws a swathe of heavy rain and severe gales eastward across all areas, a period of storm-force wind for many summits. Steams in spate, localised flooding.
Headline for Brecon Beacons
Heavy rain and severe gales soon arrive
How windy? (On the summits)
South-southwesterly 25-30mph at first, rising rapidly to reach at least 60mph over tops afternoon, and likely a swathe of speeds to 70mph+ for a time; marked increase with height.
Effect of the wind on you?
Deteriorating soon to arduous walking, increasingly difficult mobility on higher terrain, risk of a period of more severe conditions. Significant wind chill.
How Wet?
Heavy rain soon sets in
Some patchy rain just around dawn, driest east Wales, then rain soon moves in from west, setting in increasingly heavy during morning and continuing until evening, risk of torrential falls south and west areas. Showery into night. Very wet underfoot, streams in spate.
Cloud on the hills?
Soon lowering to become extensive
Initially most cloud above the hills in east, odd patches at varied heights. Soon cloud will lower onto hills, forming to lower elevations many south and western slopes; some higher breaks remain eastern mid-Wales, but likely extensive here too when rain becomes heavier.
Chance of cloud free summits?
60% at first east, soon 10%
Sunshine and air clarity?
High cloud at dawn soon thickens to overcast skies. Good visibility at first mainly eastern areas, becoming hazier, then poor as rain sets in.
How Cold? (at 750m)
4C from dawn, soon rising, reaching 9C, up to 11C for a few afternoon hours, then cooling again evening into night. Always feeling below freezing in the wind, as cold as -5C.
Freezing Level
Above the summits.

How windy? (On the summits)
Southwesterly 50-60mph, powerful gusts over tops. Just at dawn, direction more southerly with lower speed.
Effect of the wind on you?
Challenging conditions all day, maintaining balance a near-constant effort and feeling chilly despite mild temperature.

Rain and drizzle
Several hours of rain from dawn, some heavy falls, mostly on southern slopes. Rain will ease with some lingering drizzle on high terrain, a few spots of rain returning from time to time.
Cloud on the hills?
Extensive
Blanket cloud over the mountains, to low slopes in many places, to valley level south of high terrain. A few breaks approach 500-600m north of high terrain as rain eases.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Overcast, largely dull on high terrain, poor visibility. A few bright glimpses may form afternoon towards mid-Wales, but a building haze too.
How Cold? (at 750m)
Starting around 7C, sharply rising to 11 or 12C. Feeling below 0C in direct wind.
Freezing Level
Above the summits.
Planning Outlook
Stormy conditions widely across the mountains this weekend, peak wind speeds into Sunday over Scottish mountains with gusts 100mph on higher tops. Showery conditions for Sunday, turning back to snow on higher terrain in Scotland. Very wet ground conditions, beware flooding of many streams and rivers making some routes impassable. A relative lull by early Monday in Scotland, but the next weather system soon sweeps in from the southwest with more heavy rain and extensive mountain gales, continuing into Tuesday. Mild south-southwesterlies mid-late week; smaller amounts of rain, some drier windows toward east and south. Generally staying windy, particularly in Scotland. Some chance of a mid-late week ridge of high pressure in England and Wales, but unlikely to persist.
