Saturday
A ridge of high pressure persists across England and Wales. Mist and murk in the morning elsewhere will break up with brighter spells developing in central and eastern areas. A cold front over Ireland and Scotland with rain for several hours will drift gradually eastwards through the day into northwest England and Wales with thickening cloud and rain developing. Another warm day with highs at 21C in sunny spells over England, 17C in the cloudier west and north.

Saturday night
A weakening front slides southeastwards over England and Wales overnight with drizzly rain over the hills, patchy drizzle extending into the Midlands, but the front fading out to little more than a zone of cloud as it drifts further into central England. Skies clearing for Scotland will allow temperatures to dip low enough for slight frost in some glens with minima of 2 to 5C. Mostly light winds. Staying mild in the south, lows 10 to 13C.

Sunday
High pressure will be situated to the southwest, whilst a weakening cold front passes southeastwards over England and Wales through the day. This will bring cloudy skies and perhaps a little light rain for a time. Brighter skies follow. Some sun ahead of this front in the south and southeast. A few showers for north and western Scotland with a brisk westerly breeze here. Southeastern areas still quite warm, up to 19C, but it feel cooler for the north and west, nearer 13C.

Monday
High pressure influences the British Isles, bringing a fair day to England, Wales and southern Ireland, variable cloud and some sunshine, best toward the south and southeast. Fronts trail across Scotland bringing outbreaks of rain and a few showers, most frequent in the north and west. Possible showers for Northern Ireland. A keen west to northwest breeze for northern and eastern regions, lighter winds toward the southwest of Britain. A cool start, highs 11 to 16C.
