UK Outlook for Monday 28 Jul 2014 to Wednesday 6 Aug 2014:

Largely fine and dry weather is expected across most parts of the UK initially, although there is a low risk of heavy thundery showers affecting the southeast, while in the north an area of rain is expected to move eastwards through Monday. It will remain warm or very warm for many, and perhaps locally hot in places, 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 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 extending further towards the south.

UK Outlook for Thursday 7 Aug 2014 to Thursday 21 Aug 2014:

The recent generally settled conditions over southern areas are expected to persist into the first part of this period. Towards the north, rather more unsettled, with more in the way of cloud and sporadic outbreaks of rain likely. Temperatures should remain above average for southeastern parts initially, but later in the period, a change towards more unsettled conditions overall is looking likely with a higher risk of rain or showers, although there will also be some drier, brighter interludes.
