Issued at: 0500 on Fri 25 Jul 2014

UK forecast for the next 5 days

Largely fine, dry and staying very warm.

Today:

Any early mist and fog will burn back to the northeast coastline, leaving a fine, dry and warm day across much of the country. However locally heavy afternoon showers are likely in the southeast, perhaps with thunder.

Tonight:

Mostly dry and clear at first, however cloud will gradually spread into the far northwest bringing outbreaks of rain. Low cloud and mist will also return to some eastern parts.

Saturday:

Fine, dry and warm for most, especially central England.However cloud and rain will continue to move into northwestern parts, whilst the odd shower is also likely elsewhere.

Outlook for Sunday to Tuesday:

Cooler and cloudier Sunday with showery outbreaks of rain spreading south. Breezier. Mostly dry Monday and Tuesday in the south, with variable cloud and sunny spells. Northern parts staying unsettled.

Issued at: 0500 on Fri 25 Jul 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 29 Jul 2014 to Thursday 7 Aug 2014:

The largely fine and dry weather is expected to continue across most parts of the UK initially, although in the north an area of weakening and fragmenting rain is expected to move slowly southeastwards through Tuesday. It will remain warm or very warm for many, although sea breezes should keep some coastal parts a little fresher. During next week, lengthy periods of fine, dry and warm weather are likely, mainly over southern and southwestern areas, but occasional rain and brisk winds often affecting northern parts with temperatures here returning closer to average. The last part of this period should be similar, although there are indications that the more unsettled weather in the north may extend further towards the south.

UK Outlook for Friday 8 Aug 2014 to Friday 22 Aug 2014:

The generally unsettled conditions look set to continue through the start of this period with more in the way of cloud and sporadic outbreaks of rain in the north, while the best of the drier, brighter spells will be in the south and east. Temperatures should remain above average for southeastern parts initially, but returning to near normal later. A return to more settled conditions in the south is looking likely towards the end of the period.
