Further snow to come. Staying windy and bitterly cold.
Further snow through the morning, locally heavy and persistent, especially towards the south. Snow showers will gradually ease through the day but remaining largely cloudy, windy and bitterly cold, with a significant wind chill. Maximum Temperature 1C.
Snow showers continuing to ease overnight and will become more isolated. Winds will be lighter, although it will remain breezy. Very cold again, with the risk of widespread ice. Minimum Temperature -4C.
After a very cold start, many will have a dry and fine day with sunny spells. Remaining breezy but with lighter winds than on Sunday. Temperatures recovering closer to average. Maximum Temperature 6C.
Outlook for Tuesday to Thursday:
After a frosty start, dry and fine on Tuesday with lighter winds. Turning more unsettled thereafter with spells of rain and strengthening winds, although with temperatures recovering closer to average.
Day 6 to 15
After a clear frosty start across southern areas on Thursday, a band of cloud and rain will spread across all parts, followed by blustery showers, these heaviest in the northwest. Showers will die out on Friday as thicker cloud and rain spreads in from the west, becoming windy. While daytime temperatures will recover to around normal, for a time we may still see overnight frosts. By the weekend it will turn unsettled and rather cold across most parts with some prolonged outbreaks of rain, particularly in western areas. Low pressure is expected to be close to the UK by the start of Easter week, with a mixture of showers, more prolonged spells of rain and some snow likely in the north.
Day 16 to 30
There is significant uncertainty in the forecast throughout this period, but a blocked or slowly changing weather pattern is probable. There will most likely be a balance between Atlantic frontal systems affecting the south and west at times with colder air associated with high pressure out to the northeast. Mixed conditions are likely with wetter than average weather expected across the south, while staying drier and perhaps colder to the north. Further snow is possible, especially in the north. Windy conditions likely at times. Temperatures will likely be below average with further night frosts, and any milder interludes will probably be only brief.
