The UK will see a return to winter this weekend, as high pressure builds to the northeast - which will pull in much colder air across the UK from eastern Europe. Rain moving in across the south on Saturday looks to turn to snow inland - more particularly over higher ground. Then a cold northeasterly breeze will set in on Sunday - bringing snow showers to eastern areas. There are uncertainties over whether this will be a short cold snap or whether the cold will hold on into next week - with a threat of more snow.
For now, it's a cold and in many places grey start to the morning, with some fog across central areas. The fog may be rather stubborn to clear across The Midlands this morning and generally sunshine will be in short supply across many areas. A weather front will move down across the northeast, bringing some patchy rain or drizzle across eastern Scotland and northeast England. Also we have another weather front moving in across the southwest, which will spread rain east across SW England, Wales and Northern Ireland. Otherwise it will be dry across The Midlands, NW England and western Scotland. A chilly day, with temperatures reaching 3-4C in the east, 5-6C in the west.
Then after a largely cloudy but chilly night, with some patchy drizzle in places, Friday will dawn rather grey across many areas. Again, sunshine will be in rather short supply through the day, with outbreaks of patchy light rain or drizzle across the north and east, with hill snow across the north. On the chilly side across northern and eastern areas, milder across the west.
Then an increasing risk of snow over the weekend in places. A low pressure system looks to move southeast across southwest Britain on Saturday, which will bring wet and windy conditions southern areas, with a risk of snow on the northern edge of the rain - particularly over higher ground. Colder and brighter elsewhere, though a risk of snow showers arriving in the northeast later in the day. Sunday looks rather cold in a bitter northeasterly wind, most places will be dry and sunny, but snow showers will affect eastern areas.
Great uncertainty as we go through next week, with the weather models disagreeing on whether to hold on to the cold air across the UK, or bring in milder conditions from the west. But another cold day on Monday with snow showers in the east, more general rain, sleet and snow spreading south across northern and central areas later in the day. Tuesday onwards, there seems to be more weight towards there being a continuation of cold and wintry conditions - especially across the north and east, though there is a chance that milder and wetter conditions will move in from the west.
