With low pressure close by, showers or longer spells of rain affecting mainly the north and west this week, where it's least needed.
Sunday saw a lot of heavy showers and thunderstorms develop across northern and eastern Britain, bringing over 12,000 lightning strikes in twelve hours. Fortunately these intense downpours missed the Whaley Bridge area of Derbyshire, but other areas saw a lot rain in a short space of time, with some places seeing over 40mm of rain in just an hour. More heavy thundery downpours are likely through this week, with low pressure in charge, with northern and western areas bearing the brunt, with over a month’s worth of rain over a few days in places perhaps leading to further flooding.
For now, a fresher start for southern areas after quite a warm and humid day yesterday. A cold front bringing the fresher air from the Atlantic has brought a band of cloud and patchy rain eastwards this morning. The cloudy skies and patchy rain is currently towards the eastern side of Britain and will gradually clear east through the morning to be replaced by drier and sunnier skies already across SW England, Wales and Northern Ireland. Scotland will remain rather cloudy this morning, with further bursts of showery rain.
Through the afternoon, much of England and Wales will be dry and bright with spells of sunshine, just a few mainly light showers passing through fairly quickly on a brisk southwesterly breeze. Across Scotland, Northern Ireland and far NW of England we will see more in the way of showers – which will be heavy too, with a risk of thunder. There will be some sunny spells between the showers.
A fresher day for all, temperatures reaching 21-25C across England and Wales, 17-21C across Scotland and Northern Ireland.
Further showers, locally heavy, will spread northeast across Ireland, N. Ireland, north Wales, NW England and western Scotland. Also outbreaks of rain affecting the Northern Isles. Elsewhere, mostly dry with clear spells, perhaps a few light showers across the west. Temperatures falling to around 12-15C.
Low pressure will be close by on Tuesday, drifting east across northern Britain, which will drive showers, heavy with thunder in places, northeast across Britain. Showers will be heaviest and most frequent across northern and western areas, fewer across southern and eastern England – where there will be more in the way of sunshine. But it will be breezy across the south, lighter winds across Scotland. Showers will be slow-moving across northern areas, so exacerbating the risk of flooding from more intense downpours. Temperatures reaching 18-20C across the northern half of Britain, 20-23C across the southern half.
Low pressure across the north will gradually move out into the North Sea on Wednesday, but close enough to bring another day of showers across Scotland, N. Ireland and northern England, locally heavy with hail and thunder. Fewer showers further south, any showers mostly likely in the morning, the afternoon mostly dry and sunny. Temperatures reaching 16-19C across the north, 20-23C in the south.
Thursday looking to stay mostly dry and sunny through much of the day, though cloud will build to bring a few showers across Scotland and NE England. Later in the day though, a fairly deep area of low pressure for early August will spin northeast towards Ireland. Some uncertainty over timing and track of this low, but it looks to spread outbreaks of heavy and thundery rain north and east across Britain Thursday night and Friday morning, while bringing increasingly windy conditions to the south and west, with gales around coasts.
Outbreaks of heavy and thundery rain clearing northern and eastern areas Friday morning, followed by fresher, brighter but windy conditions from the southwest, with showers developing – heavy and thundery in the north and west. Gales around southern and western coasts.
