Fan Fawr weather forecast.

A mixed day on Fan Fawr: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 800-1600 m) - clear summits. Cloud will be lowest on the NW slopes, down to about 800-1100 m; the SE side should be clearer, lifting to around 900-1200 m. Little or no rain expected. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.
