Thursday
A day of mostly dry conditions and sunny spells, however, the north of Scotland (and particularly northwest) will see thicker cloud cover and some patchy rain for a time. A similar pattern will occur in northwest Ireland. Over England and Wales, northwestern coastal areas will be more often cloudy, fair weather cloud building across England. One or two showers cannot be ruled out in central and east England. Highest temperatures approach 30C on the southern England/Wales border, 25C Ireland and east Scotland, 17 to 20C west Scotland.

Thursday Night
Skies over eastern parts of Scotland and Ireland will clear into nighttime, and more widely clear across England and Wales; the southeast of England may hold on to some more cloud. Northwestern Ireland and Scotland will stay cloudier with light spots of rain. In the later overnight hours, a few more steady patches of rain will reach northwestern areas as well, but remaining light in nature. Scotland becomes quite breezy as well, notably along the west coast. Lows at 10 to 12C north and western areas, to 14 to 16C in the south and east of England.

Friday
Cloudier start across the far south of England and in the north of Scotland, while elsewhere sees sunny spells. A few spots of rain expected across north and west Scotland and northwest Ireland. Dry elsewhere. Later in the day, spots of rain will turn into more persistent rain across northern parts of Scotland, with patches spreading further across Scotland and into Ireland as evening turns to night. Cloud becomes fairly extensive across northern areas too. Highs at 14C to 19C across Scotland, 18 to 24C across northern England and Wales, approaching 30C in southern England.

Saturday
On Saturday, an Atlantic front will sweep south and east through the country. Patchy rain in the morning across most of Ireland and Scotland, some heavier persistent falls in coastal areas. Patchy rain and cloud will sweep into Wales and England as well, most rain again in northwestern areas; becoming windy as well. Southeast England stays driest with some sunny spells. With time, some sunny spells may break out in Scotland and Ireland as well, but always with a risk of rain returning. Highs of 17 to 20C Scotland, to 28C southeast England.
