UK Outlook for Thursday 29 Mar 2018 to Saturday 7 Apr 2018:
Thursday looks to be cold across the UK, with a few wintry showers possible in the north. Later on Thursday and into Good Friday, southern parts of the UK will probably see outbreaks of rain whereas further north this could bring a risk of sleet or snow at times. For the rest of the Easter weekend, it's still too early to forecast in much detail, but it looks to be unsettled with a mix of sunny spells, showers, longer spells of rain and some snow, mainly in the north. The driest and brightest conditions will be in the northwest. Frost overnight but perhaps milder in the south at times. Further ahead, the weather may become more settled, with brief interludes of wintry showers, and rather cold, with frost at night.
UK Outlook for Sunday 8 Apr 2018 to Sunday 22 Apr 2018:
Colder than average conditions are likely to prevail overall through the middle part of April, with frost likely overnight. In the north the weather looks to be fairly settled although there will be a few wintry showers. Further south, there may be more in the way of wet and windy weather at times, and showers, perhaps wintry. Later in the month, it is possible that we could start to see some warmer weather, with less cold nights, and it may become drier generally.
