Bitterly cold with strong easterly winds; prolonged snowfall.
This Evening and Tonight:
Snow showers will continue on and off this evening, with bitterly cold winds. Through the early hours and area of more prolonged drifting snow will move into the southwest, bringing significant accumulations and potential for disruption. Minimum Temperature -3C.
Snow will fall through the morning, bringing further accumulations, especially over the Moors but also to lower levels with potential for disruption. Snow will ease later from the east. Maximum Temperature 3C.
Outlook for Monday to Wednesday:
It will be an icy start on Monday, turning drier and mainly sunny up to mid-week with lighter winds. Less cold by day, but further overnight frosts.
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.
