How windy? (On the summits)
Southwesterly 10-20mph at dawn, strengthening to 30-35mph afternoon, sometimes 40mph high tops.
Effect of the wind on you?
Fairly small at dawn, deteriorating to strenuous walking, strongest wind challenging stability with wind chill.
How Wet?
Patchy rain, later setting in
Patchy rain drifts from the southwest from morning, plenty of dry windows, but rain increasingly frequent afternoon, probably setting in persistently for several hours, heavy falls south and west slopes.
Cloud on the hills?
Fairly extensive, some early breaks
High terrain shrouded from dawn, likely 500-600m upward; some morning periods of higher bases, any breaks to summits brief. Then more extensively shrouded afternoon from 400m up, higher bases east of Brecon.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Mostly overcast, rare glimpses of weak sun early. Very good visibility below cloud, deteriorating later in rain.
How Cold? (at 750m)
11 to 13C, mildest east. Feeling like +1 to 3C in strongest wind.
Freezing Level
Above the summits.
Planning Outlook
Through Monday, cloud will return from the southwest and bring some patchy rain with it. From Tuesday onward, a variable southwesterly will dominate through at least mid-week. Windy at times with periods of rain, drizzle and low cloud most persistent in the west; Tuesday into Wednesday is likely a wetter and unsettled period, with the unsettled weather lingering well into Wednesday in Scotland. Warmest in England and Wales, but may stay cooler in Scotland as low pressure to the northwest recycles air from the north Atlantic back onto the Munros. Pressure generally trending higher later in the week, centred southeast of England, but low pressure to the west of Ireland will prevent any extended settled periods with more windy, wet weather at times next weekend; temperatures likely become more widely warm.
