Uk Snow Weather Maps Show Arctic Air Bringing Midweek Chill
uk snow weather maps point to a colder spell from mid-week as Arctic air moves south across the UK, with showers expected on most days and snow possible on Scottish mountains later in the week. Temperatures are set to stay below average for early May after a weekend that still produced 22.9C at Wiggonholt in West Sussex.
Saturday split the country sharply, with maximum temperatures staying in single figures across northeast England and southeast Scotland. By Wednesday, colder Arctic air is expected to reach all parts of the UK, bringing heavier showers, hail and thunder as the pattern turns unsettled.
Sunday To Tuesday Shift
Sunday was expected to turn cooler across southern England, East Anglia, the south Midlands and south Wales under a brisk northeasterly breeze and cloud. A weak cold front was due to clear south across the area, with some light rain grazing the far southeast in the morning. Northern Scotland was expected to turn wet and windy, while southern Scotland, Northern Ireland, north Wales, northern England and the north Midlands were set for a fine, dry and sunny day.
Temperatures on Sunday were expected to reach 11-14C in the north and 13-16C in the south. Overnight, a band of cloud and showery rain was due to move south across Scotland into northern England, and clearer skies were expected to bring patchy frost by dawn in Scotland.
Monday was set to bring another band of cloud and showery rain along a weakening cold front across England and Wales, reaching southern England early afternoon. Drier conditions with sunny spells were expected from the north elsewhere, with the odd light shower possible there. Temperatures were expected to reach 11-14C at best generally, and perhaps 15-16C in the southwest.
Greenland Low Across Scotland
On Tuesday, a further weakening cold front was expected to move southeast across the UK, reaching the southeast early evening. Most places were set to see only patchy rain, but blustery showers were expected in the northwest.
That pattern changes Tuesday night, when an area of low pressure originating from Greenland was expected to drop southeast across Scotland and then move on over the North Sea. It was expected to pull weather fronts down across the UK before colder Arctic air spread south on Wednesday.
Arctic Air And Frost Risk
From mid-week, showers were expected to become heavier as the Arctic air arrives, with hail and thunder developing on Wednesday as sunny spells warm the surface. Later in the week, the risk widens to widespread frost at night as skies clear, particularly after the colder air settles in.
For readers in Scotland, the most direct effect is the snow risk on mountains later in the week. For much of the UK, the change is to a colder-than-average early May spell with repeated showers, lower daytime temperatures and sharper night-time drops once skies clear.
