The Met Office has issue a yellow weather warning for snow and ice across the East of England today and overnight.
Showers of sleet and snow are said to be likely at times today and overnight into tomorrow, when they will also affect some southeastern parts of England, although showers should generally be a mix of sleet and hail near the coasts.
Up to 2cm of snow is likely in places at low levels, while between 2-5cm is expected over hills.
Motorists are being warned of potentially difficult driving conditions, with ice creating an additional hazard overnight, particularly after any showers.
This warning will last until midday tomorrow, with a further warning southwards across some central and eastern parts of England, mainly from late evening tonight.
The Met Office says: “The colder airmass already established across Scotland and the north of England will continue south to affect most other parts by Sunday evening.
“Showers will feed in on the north to northeasterly winds, particularly affecting the more northern and eastern parts of Scotland, along with northern England during Sunday daytime, but progressing further south into the north and east Midlands along with parts of east and southeast England during Sunday evening and overnight into Monday.
“Not everywhere will see the snow showers, but some may become aligned in bands from time to time, leading to the risk of some moderate accumulations of snow, most likely over northern Scotland and northeast England.
“Ice will also be a hazard on untreated surfaces, particularly between showers overnight, with those areas just inland from the coasts of eastern and southeast England at particular risk as the showers will fall as a wintry mix.”
