Wednesday
Several fronts sweep northeast across the country, bringing a spell of rain to many places. The most persistent rain, drizzle and low cloud will be over Wales, northwest England, and later southwest Scotland and Northern Ireland. Rain later moves into north and east Scotland, with some heavier falls move across more northern areas with time. Scattered showers follow behind in England, with the driest conditions in east England with bright spells. A breeze picks up as well. Highs 16 to 18C north/northwest areas, to 20 to 24C south, warmest southeast parts of England and Ireland.

Wednesday Night
Staying rainy in the north of Scotland for a time, but the major band of rain clears north overnight, leaving behind a brisk westerly wind and patchy showers onto west coastal areas. A generally cloudy evening, the best of clear sky windows across England and east Scotland. Any showers will gradually ease in intensity with time. Lows at 12 to 14C in Scotland, to 15 to 17C in England and Wales, always mildest east areas.

Thursday
West-southwesterly breezes prevail, bringing patchy rain to some western areas though most will stay dry with sunny spells. More persistent rain reaches the west of Ireland with time and later spreading into northwest England and Scotland, setting in persistent and heavy for several hours in western areas. Quite warm in the south with highs of 23, to up to 27C in the urban southeast. Cooler north where highs approach 16 to 18C.

Friday
Rain will ease from northern and central England and Wales first thing as the cold front moves into southern England, allowing for the south to see patchy rain through the morning. This easing off into the afternoon though patchy rain still affecting southeast England later in the day. Spells of rain across north and west Scotland into the far northwest of England where it will also be windy, a risk of gales along the western Scottish coast. Otherwise dry with sunny spells. Highs at 14 to 18C in the north (mildest temperatures east), to 20 to 24C in England, again mildest in the southeast.
