Rain reaching western areas later on Sunday is likely to turn to snow across parts of Scotland and northern England and give a period of snow lasting some 3-6 hours in places before easing from the west across southern Scotland and northern England during the early hours of Monday. The snow may then persist across parts of northeast Scotland well into Monday. Across the Yellow area locally 1-3 cm of snow is likely to accumulate at lower levels, but with up to 5 cm above around 100-150 m and locally 5-10 cm above 200 m over Scotland, mainly to the north of the Central Belt. There is a risk of over 15 cm falling over the Grampians and Highlands.
The public should be aware of the risk of disruption to transport
A frontal system will move eastwards into the UK later on Sunday and then slowly northeast across Scotland on Monday. As this frontal system meets very cold air already over many parts of the UK, the rain is expected to turn to snow across northern and some eastern areas. The extent to which rain turns to snow is very dependent on its timing and intensity hence the situation remains finely balanced. However, at present it looks as if the greatest risk of significant snow is over the northern half of the Yellow area. Although there is reasonable confidence that the snow will clear much of southern Scotland by Monday’s peak period, there is considerable uncertainty regarding how long the snow will persist across NE Scotland. The situation will be monitored so please watch for possible updates to this warning.
