UK forecast for the next 5 days

This Evening and Tonight:

Heavy showers in the far southeast will slowly clear away overnight, then leaving most places dry with long clear periods. Northwestern areas will become increasingly cloudy though, with occasional rain and drizzle.

Increasingly breezy with scattered showers in northwestern parts. Elsewhere, mostly dry and bright, but turning cloudier with patchy light rain spreading southeast. Rather warm, especially in the southeast.

Issued at: 1700 on Mon 28 Jul 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 2 Aug 2014 to Monday 11 Aug 2014:

Changeable this weekend with showers and or more prolonged periods of rain affecting most areas. On Saturday, rain, occasionally heavy and perhaps thundery, will clear away eastwards, with brighter conditions but also scattered showers then following. Further showers on Sunday with a chance of more persistent rain reaching some western areas later. The unsettled theme then continues into next week, conditions perhaps turning breezier then, with a risk of gales in some exposed western parts. The unsettled theme is likely to continue until the end of the period, although there may be more in the way of drier and brighter conditions developing across the south and east later. Temperatures should be generally near normal for the time of year, although perhaps on the warm side towards the south and east.

UK Outlook for Tuesday 12 Aug 2014 to Tuesday 26 Aug 2014:

With no particularly strong signals regarding weather patterns over the UK during mid-August, conditions are more likely than not to be close to climatology. As such most regions can expect to see periods of fine weather with some sunshine interspersed by occasional spells of more changeable conditions with showers or rain. Northern parts are perhaps most likely to see the most frequent bouts of unsettled weather leaving southern parts with the most prolonged fine spells. Daytime temperatures are then likely to often be above average during fine spells.
