Low pressure affects the northern part of Britain through Tuesday. A cold front passes southeastwards early in the day, giving heavy rain for a time in England and Wales. It will be a chilly day with heavy showers spreading from the northwest behind the cold front. A few brighter spells, the best of these in the northeast. Snow over high ground in the north and west and a risk of hail and thunder. High temperatures at 5 to 11C.
Showers easing for most through the evening and overnight into Wednesday though they will likely persist over the north of Scotland and for western and eastern coastal areas, particularly those exposed to the brisk northerly wind. Clear spells will develop elsewhere and this is where we are mostly likely to see a frost develop. Some icy patches are possible too on untreated surfaces. Overnight lows widely falling to -2 to 2C.
A chilly northerly wind and an area of low pressure over the North Sea will bring clusters of showers, most frequently for northern Scotland, with snow over the hills. Wintry showers will also affect eastern coasts of England. Bands of showers also making their way into western Wales and southwest England. Hail and thunder possible at times. Some good sunny spells will develop for central areas. High temperatures at 5 to 9C.
A very complex set up on Thursday with low pressure over the North Sea which will possibly track westward over Scotland through the day. Through the morning this will bring showers to northern parts of the country which will fall as snow over higher ground in Scotland, the north of England and Wales. Through the afternoon showers will spread into Ireland and southern parts of England too. A breezy day for the northern half of Scotland. High temperatures at 6 to 10C.
