Patches of cloud above 800-1000m in morning, but breaks forming to many higher slopes through middle of day. Locally around showers, patches will form below 700m.

Varied conditions beyond midweek as complex lows pivot eastwards across Britain. Most rain may well be focused across England, Wales & southern Scotland, with only well scattered showers for much of the Scottish Highlands - excellent visibility and good cloud breaks. Some marked lulls in wind, but for periods up to gale force - northerly by Friday. Generally chilly up to Saturday with higher mountains near or just below freezing point, and overnight frost in some valleys. Over the weekend, westerly winds are expected to return, with rain, low cloud and less cold temperatures.
