Bitterly cold and windy with further snow showers.
Outbreaks of snow affecting many areas will turn mostly light and showery. Turning dry in many places with some brightness by the afternoon but remaining generally cloudy. Windy with significant wind-chill, as temperatures struggle to exceed freezing across many areas. Maximum Temperature 2C.
Light snow showers affecting some parts will die out with clear spells becoming more widespread as cloud breaks develop. Penetrating frost with bitterly cold winds remaining brisk. Minimum Temperature -4C.
A little less cold on Monday with sunny spells and winds slowly decreasing. Thaw of lying snow. Northeasterly winds continuing to make it feel colder than normal. Maximum Temperature 4C.
Outlook for Tuesday to Thursday:
Turning increasingly mild by day with local mist Tuesday night. Some bright or clear spells, with Thursday turning cloudier with freshening winds probably bringing rain and drizzle later.
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.
