Summary for all mountain areas
Brisk westerly winds will give considerable chill factor over high terrain - air temperature near freezing on higher Scottish tops. Showery conditions - the most frequent precipitation in northwest Scotland in morning, falling as snow on Munros, also hail to lower levels. Showers become more scattered during afternoon.
Headline for Brecon Beacons
Breezy on tops; a few brief showers, mostly west in morning.
How windy? (On the summits)

Scattered showery rain, mostly western Cambrians in the morning, risk brief locally heavier bursts with hail. Brief showers passing eastward afternoon, but many places often dry, especially in south.
Cloud on the hills?
Lifting mostly above tops
Patchy cloud mostly western areas in the morning, likely to come and go on highest tops, briefly to 600m in west at first, and grazing tops elsewhere briefly around showers, but much cloud lifting from tops.
Chance of cloud free summits?
60% rising to 90%
Sunshine and air clarity?
Brief bursts of sun, some sun more often toward coast later in day. Visibility often excellent, briefly reduced locally during showers.

Little if any
Most cloud above the hills all day, rare patches may graze high tops.
Chance of cloud free summits?
90%

1C rising to 4C afternoon. Where exposed to wind, feeling like -5C early in day, later -2C.

Planning Outlook
High pressure expands over the British Isles on Sunday to bring a quieter day with lighter winds and only isolated showers. A scattering of showers on Monday as a cool east-northeasterly wind develops, but plenty of dry weather too. High pressure stays nearby to the north of Britain through the week ahead giving a run of dry days with sunshine typically best in the west, but many mountains often free of low cloud. A cool easterly wind is likely to prevail for England and Wales, strongest toward the south, whilst Scotland has often lighter winds. Some overnight frosts. Daytime temperatures near average, typically a few degrees above freezing on high tops through midweek.
