A cold and clear night ahead as showers ease. This will allow temperatures to drop and a frost to develop.
As an area of rain hits the colder air during the early part of Monday morning it will readily turn to snow.
Significant accumulations are expected by dawn over higher ground, but snow could fall to lower levels for a time before turning back to rain.
This could lead to travel disruption, especially for the Monday rush hour.
Here are the latest warnings. For all updates visit the Met Office Warnings Page.
SNOW: 3am until 10pm Monday - SW Scotland and The Borders
Snow is expected to spread northeastwards into Scotland early on Monday, perhaps even falling to low levels during the morning rush hour across and to the south of the Central Belt of Scotland, before spreading northwards into the rest of the warning area.
Across the south of the warning area, snow may turn to rain during the afternoon, but further north, and especially on higher routes above 200m, significant accumulations of snow may occur during the afternoon and evening. Here, 2 to 5 cm snow is likely above 100 to 200m whilst above 300m 10 to 20 cm snow may build up.
RAIN & SNOW: 2am until 3pm Monday - Cumbria and the North East
The bulk of accumulations will be above 200m where 2-5 cm is likely in many areas whilst above 300 to 400m 5-10 cm is expected.
At lower levels accumulations will be smaller, patchier and shorter-lived and it may be that little, if any, snow falls in some eastern coastal areas. A brief spell of freezing rain is possible as snow begins to turn to rain, leading to icy stretches.
Meanwhile, given saturated ground and recent flooding, the combination of snow melt and rain may also bring about some disruption.
Across northern England, snow will turn to rain from the south and west through the course of the morning.
