Outlook for the UK over the next 6-30 days

UK Outlook for Friday 30 Jun 2017 to Sunday 9 Jul 2017:

Friday is likely to become breezy and showery across the country. Saturday could well be drier for a time before further rain moves in during the evening or overnight. Sunday and the following week will stay changeable with showers or longer spells of rain. There will also be some drier and brighter spells, which will be most likely in the south and east. In the northwest, showers are likely to be heavier, perhaps bringing a risk of thunder at times. It will sometimes be windy, especially in the north and west where there will be a risk of local gales at times. Temperatures are expected to stay near the seasonal average throughout, or be rather cool.

Updated at: 1326 on Sun 25 Jun 2017

UK Outlook for Monday 10 Jul 2017 to Monday 24 Jul 2017:

The changeable weather is likely to continue in the north 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 in the south and these may spread further north as we head into the second half of the month. These would bring more in the way of sunshine and higher temperatures, and there could be some very warm spells. However, an increase in temperatures would pose the threat of some thundery showers.
