Weekend: South Dry With Warm Sunshine, North Cooler & Windy With Rain At Times
There will be a north-south divide across the British Isles this weekend. High pressure will ensure a dry and sunny weekend across the south, turning warmer by day too, with temperatures reaching 25C across SE England on Sunday. A deep area of low pressure passing to the north of Scotland will bring cloud and rain to Scotland and N. Ireland today, it will be very windy in the far northwest too. A cold front associated with low pressure to the north slowly slips south towards central areas on Sunday, bringing cloud and rain to N. Ireland and northern England, while turning cooler and brighter across Scotland.
For now, much of Britain has started the weekend on a dry, bright or sunny note, but it’s also chilly inland, with some spots falling as low as 3-4C overnight. However, from the central belt of Scotland across to N. Ireland northwards it’s a cloudier and windier picture, with outbreaks of rain across much of northern Scotland, heavy locally across higher ground. NW Scotland is also experiencing gales, with gusts of 45-60mph.
A deep area of low pressure moving east between Scotland and Iceland will bring tightly packed isobars across the far north today, so northern and western Scotland along with Northern Ireland will see gales. Also, a frontal system associated with low pressure passing to the north will slide southeast across northern Scotland and towards N. Ireland through the day, bringing cloudy skies and rain across northern and western Scotland through much of the day, rain persistent and heavy over western slopes. The rain spreading towards the central belt of Scotland and N. Ireland by early evening.
South of central Scotland and N. Ireland, it will be a mostly dry and sunny day, prolonged sunshine across England and Wales. Temperatures in the sunshine reaching 21-23C, far north of England northwards reaching 15-19C.
Into Saturday night, it will remain very windy across Scotland and N. Ireland, with gusts of 40-50mph, across the Northern Isles we could see gusts of 60-70mph. Outbreaks of rain will spread southeastwards across all of Scotland, N. Ireland and eventually arriving across northern England through the night but rain turning lighter, clearer but very windy conditions following across northern Scotland. To the south dry and mainly clear skies. Temperatures falling to 9-11C where skies clear, but where it’s cloudy 11-14C.
A band of cloud with patchy and mainly light rain will lie across southern Scotland, northern England, N. Ireland and perhaps north Wales to start Sunday. This is an east-west cold front stretching west across Ireland and out into the Atlantic, the front will be slow-moving and wriggle around, with pulses of more persistent and heavier rain spreading from the west across N. Ireland, southern Scotland and northern England into the afternoon. Cooler, fresher and brighter to the north of the central belt of Scotland, dry to the south of the band of rain across south Wales, Midlands, southern England and East Anglia, best of the sunshine towards the southeast, cloudier towards the west. Temperatures in the afternoon reaching 25C in London, 22C in Norwich, 21C in Manchester and Cardiff. But to the north of the cold front lying across northern England, cooler and fresher, with temperatures reaching 14-17C.
A weakening cold front will continue to slide south on Monday, clearing southern areas by the afternoon after perhaps a cloudy start, but nothing more than patchy drizzle before it clears. Sunnier but cooler fresher conditions across northern and central areas in the morning spreading down across all parts into the afternoon with a northwesterly breeze, temperatures reaching 19-21C in the south, 15-18C in the north.
High pressure will build in from the west from Tuesday and sit across the UK for much of the week before retreating east by the weekend. So for most it will be a dry and fine week with sunshine by day. Some chilly nights at first with light winds, clear skies and longer nights, but turning a little warmer towards the end of the week, as high pressure shifts easts and a milder southerly flow picks up.
