Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 27 Jun 2017 to Thursday 6 Jul 2017:

Changeable weather is likely to continue at the start of this period with rain on Tuesday clearing to sunshine and showers on Wednesday. These are likely to be heaviest in the north and northeast, where it may be windy at times, with the best of any drier spells likely in the south and southwest. The rest of this period will remain unsettled with further bouts of showery rain, perhaps heavy and thundery at times, interspersed with brief drier and brighter spells, these most likely in the east. It will often be windy, especially in the north and west where there is a risk of local gales at times. Temperatures will be near normal or rather cool, especially compared to recently, although it may be warmer at times in the southeast.

UK Outlook for Friday 7 Jul 2017 to Friday 21 Jul 2017:

The changeable weather is likely to continue at first, bringing further showers or longer spells of rain with only brief bright or sunny spells in between. However, drier and warmer spells are likely to become more prevalent during the second week of July and these may perhaps become more widespread as we head into the second half of the month. This will bring more in the way of sunshine and higher temperatures, with perhaps some very warm spells possible. However, an increase in temperatures also poses the threat of some thundery showers.
