West to southwesterlies, often gale force over the mountains in the second half of this week. Heavy rain most prolonged in the west where increasingly wet underfoot, streams rising to be in spate. Low cloud often covering the hills. Temperatures varying, some notably cooler days for Scotland, at times more humid air mainly toward the south.
