Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 28 Feb 2017 to Thursday 9 Mar 2017:

A fairly unsettled picture is likely at first, as further weather systems affect the UK from the Atlantic. Sunshine and showers are likely for many areas at first. Further frontal zones then bringing cloudier, wetter weather, particularly in the north west; with some snow over northern hills. Feeling colder than of late, especially further north, with temperatures closer to average in the south. The changeable Atlantic influence could remain in place through early March, with stronger winds and rain more likely in north and western areas; drier and brighter further south and east, but temperatures returning to around normal. There is a smaller probability of more settled conditions developing on the continent, which could bring a greater risk of overnight fog and frost particularly for eastern UK.

UK Outlook for Friday 10 Mar 2017 to Friday 24 Mar 2017:

For the rest of March signals are weak and confidence is low. There could be spells of wet and windy weather, interspersed with brighter and showery conditions with some snow possible across the north of the UK. There could, however, also be some drier and brighter spells, particularly in the south and east where we may see some local frost and fog at times overnight. Temperatures are expected to be around average for the time of year but there remains a small chance of seeing a more prolonged cold spell, if settled conditions were to develop more widely. This is more likely later in the period.
