Low cloud and visibility

Extensive cloud likely obscuring hills above 400m in the north and some low-level fog possible in the south overnight and early morning. Cloud lifting and clearing largely above hills during the afternoon but deteriorating again into the evening with bases expected to lower onto mid and high slopes (above 400m or so). Outside of low cloud and fog, visibilities mostly hazy or very hazy in the early morning, then hazy or good through the afternoon. Probably hazy or very hazy into the evening.
