Met Office Chief Meteorologist, Paul Gundersen, said: “A deep area of low pressure is bringing heavy rain to Wales, Northern Ireland and western Scotland today as well as strong winds to the far north of Scotland at first. Elsewhere, low cloud and muggy conditions dominate the south.
“Sunny spells are expected in the southeast and north tomorrow, but rain continues to affect the northwest, with 50–80mm of rain possible in Cumbria within 24 hours.
“The southeast will see a brief spell of very warm, muggy weather over the coming days as warm air is pulled in from the south. Highs of 24°C are expected today and of 26–27°C tomorrow. This is unusually warm for the second half of September but not exceptional.”

Weekend Weather
As we head through Saturday and into Sunday a new low-pressure system moves in from the southwest bringing heavy rain, strong winds and a risk of thunderstorms, which will gradually ease through Sunday as the weather becomes more showery but fairly cool. Yellow National Severe Weather Warnings hve been issued for parts of northern England, southern Scotland, western Wales and Northern Ireland.
Met Office Deputy Chief Meteorologist, Tom Crabtree, said: “Through this period 20-40 mm of rain is expected to fall widely, with some locations perhaps seeing 60-100 mm, with much of this total falling in just a few hours. From mid-Saturday onwards, increasingly strong gusty winds and perhaps some thunder will also accompany the rainfall, further increasing the risk of disruption.
“Strong winds are also likely in southwest England, western Wales and later parts of the northeast. These may potentially exceed 55 miles per hour, however, the exact location and timing remain uncertain at this time. We’re closely monitoring developments and may issue more warnings as the situation evolves. It’s important to stay up to date with our forecasts over the coming days.”
As the low-pressure system pulls away to Scandinavia late on Sunday a cooler air mass will spill in from the north, replacing the recent warmth and there is a chance of snow over the very highest mountain peaks by the end of the weekend.
Looking further ahead
High pressure is expected to build, bringing a brief spell of more settled weather.
