A mixed day on Foel Goch: summit wind broadly 15-30 mph, with gusts 35-45 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 600-1100 m) - clear summits. Cloud will be lowest on the W slopes, down to about 500-800 m; the E side should be clearer, lifting to around 700-1000 m. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. 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.
