Outlook for the UK over the next 6-30 days

UK Outlook for Friday 24 Feb 2017 to Sunday 5 Mar 2017:

Plenty of dry and sunny weather is expected on Friday, with one or two showers, but it will feel cold. Wind and rain is then likely to spread in from the west later and last through Saturday but it will be accompanied by milder air. Changeable and mild weather is likely to continue through the rest of that weekend and into the following week, with wet and windy conditions affecting the north and west of the UK the most. The south and east should see the best of any drier and brighter weather. However, there will generally be brighter, cooler, more showery days in-between weather systems. This changeable pattern is currently expected to continue as we head into March.

UK Outlook for Monday 6 Mar 2017 to Monday 20 Mar 2017:

For March there is a fair amount of uncertainty, but the weather is most likely to be unsettled at first. There will be spells of wet and windy weather, interspersed with brighter and showery conditions with some snow possible across the north of the UK. There will, 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 a little above normal for the time of year but there remains a small chance of seeing a more prolonged cold spell, which is most probable later in the period.
