    Outlook for the UK over the next 6-30 days

    UK Outlook for Thursday 27 Feb 2020 to Saturday 7 Mar 2020:

    Unsettled and often windy conditions are expected to continue with areas of rain moving east across the UK, interspersed with brighter, showery interludes. Rain is likely to be heaviest across western and northwestern areas, especially over the hills, with the best of any more prolonged drier interludes in the south and east. There is an increased chance of deep low pressure systems affecting somewhere in the UK, causing large amounts of rainfall and very strong winds. Temperatures are likely to frequently oscillate between rather cold and rather mild, with large diurnal variations. During any colder interludes, there is likely to be some snow on the high ground of the north. The weather may become more settled in the southeast at the very end of this period, though remaining unsettled elsewhere.

    UK Outlook for Sunday 8 Mar 2020 to Sunday 22 Mar 2020:

    A continuation of the unsettled weather is expected at first, with spells of rain and strong winds broken by brighter, but showery conditions. The heaviest rain and strongest winds are expected in the northwest, with drier conditions expected in southern and eastern parts. It appears likely that conditions will turn generally more settled by the middle of March, with more prolonged dry spells possible, especially in the south. Any further spells of wet and windy weather most likely in the north. Temperatures mostly above average, but there will be large diurnal variations should more settled conditions take control, with frosts becoming likely.
