UK Outlook for Wednesday 7 Mar 2018 to Friday 16 Mar 2018:
Further rain, sleet and snow are expected at times on Wednesday and Thursday. Northern parts are likely to see the snow, whereas rain or sleet are more likely further south. Some central and eastern parts may stay dry. It will remain very cold in the north though with brisk winds. In the south, it will be less cold, but cloud, mist and fog are likely, which may be slow to clear during the day. In subsequent days, it is likely to stay cold in the north, but temperatures may return nearer normal in the south, but still below average. Rain and strong winds are likely across the UK, perhaps turning to snow across central and northern parts. The best chance of drier weather will be in the far northwest.
UK Outlook for Friday 16 Mar 2018 to Friday 30 Mar 2018:
The predominately easterly wind is likely to persist for a while across the north with colder than average weather here, but it may be a little milder at times in the south and southwest of the UK. There will continue to be a risk of snow across some central and northern areas, but in the far north and northwest it is likely to be drier. Night frost and ice will continue to occur at times. Later in March it may turn more unsettled and lh milder as westerly or southwesterly winds return. The timing of more Spring-like weather remains uncertain.
