A mixed day on Ben Donich: summit wind broadly 15-35 mph, with gusts 40-50 mph early in the morning (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 600-1100 m - the top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon. Cloud will be lowest on the NW slopes, down to about 700-1000 m; the SE side should be clearer, lifting to around 900-1200 m. Little or no rain expected. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up.
