Summary for all mountain areas
A cold front will move southeastwards brining a few hours of precipitation - although still some uncertainty in its exact shape and position. Snow and hail showers will affect W Scotland whilst most other areas will have a few hours of rain, in places finishing as snow, as the temperature drops.
Headline for Brecon Beacons
Rain for a few hours. Intermittently windy.
How windy? (On the summits)
Changing through day: Initially southerly 40mph, then a lull before westerly 30mph afternoon.

Rain and snow for a few hours
Two to four hours of precipitation morning and middle of day, turning to snow highest tops before clearing around mid afternoon from west.
Cloud on the hills?
Blanket of low cloud probable; cloud base may rise or have risen from west
Cloud may well fill in or have filled in across the hills in rain. There may be improvement from the west but this very uncertain.

50%

Planning Outlook
Mostly cloudy with precipitation from time to time over the next few days - although total rainfall is now expected to be fairly small on most mountains, particularly N Scotland. Temperature wise, it is highly likely to remain colder than recent January's with the snow pack across the Scottish Highlands being enhanced by further snowfall, whilst further south snow accumulates on higher areas, and occasional falls reaching lower slopes.
