Outlook for Wednesday to Friday:
Wednesday, a frosty start then dry, but a risk of rain in north later. Thursday and Friday will also be mild but more unsettled with spells of wind and rain.
Day 6 to 15
The weekend will be unsettled with sunshine and showers for most, although some longer spells of rain are possible, with perhaps some hill snow in the north. It will be windy, with coastal gales at first. Temperatures will be slightly below normal and locally rather cold, with a risk of overnight frosts, chiefly in the north. During the final week of March the UK's weather is likely to stay changeable, with showers and rain at times, interspersed by drier and brighter interludes. There remains some uncertainty in the forecast for the Easter Weekend, but we are likely to see slow moving weather systems across the UK, with wetter weather more probable in the south. and with drier, colder conditions in the north albeit with a risk of snow at times.
Day 16 to 30
There is significant uncertainty in the forecast detail during this period, but it does look as though slow moving weather systems will affect the UK. There will most probably be a balance between Atlantic frontal systems affecting the south and west at times, with perhaps colder and perhaps drier conditions in the north. However, further snow is possible at times, more especially in the colder north. It will be windy in places with below average temperatures; some overnight frosts are likely during early April. Towards the middle of the month confidence becomes very low, but some warmer days are expected and it may become drier generally.
