Low-pressure is expected to be centred just east of Scotland on Wednesday. This is going to be bringing an unsettled day to all areas, bringing cloudy skies and outbreaks of rain for many, particularly across Scotland and northern England. After a mainly dry and bright start across central and southern England and Wales, rain and showers will spread in. Some regions will see thundery showers with the risk of hail and local torrential downpours. As is the nature of showers one or two places may escape them. Highs at 16 to 22C, warmest in the east. A moderate to fresh westerly wind in the south.
Showers across many regions of England and Wales will fizzle out overnight, however with winds being west to north-westerly showers are expected to continue along northern and western coasts. Ireland and Northern Ireland as well as northern and western Scotland will continue to see showers, these at times merging into longer spells of rain. Lows at 8 to 13C.
The rather brisk wind flow tending to turn more to the west or north west through Thursday. A front will sink southwards bringing some showery outbreaks of rain across Ireland and southern Scotland and eventually to northern England. A chance of a few thundery showers across England and Wales but mainly dry here with some sunny spells as well. More rain moving in to northern and central parts of Scotland later. Highs at 15 in the far north, 22C in the south.
Thundery showers and some rain may affect central and southern parts of England and Wales on Friday as a developing system tracks east through the Channel. Some clouds and spots of rain across Ireland and Northern Ireland as well as northern England. Probably brighter across central and northern parts of Scotland with some sunny spells. Highs at 15C in northern Scotland, 22C in southern England.
