Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 8 Jul 2015 to Friday 17 Jul 2015:

Bright and breezy on Wednesday with a mixture of showers and sunny spells for many places. However, it is likely to be cloudier in the north with some longer spells of rain developing here. Less windy on Thursday with the showers becoming restricted to northern parts, with mostly dry conditions and some periods of sunshine developing elsewhere. After this, a fairly quiet period of weather leading into next weekend and the following week, with mostly dry conditions across southern parts but perhaps some rain at times in the north. Temperatures during this period will tend to drop a little below normal to start with, this feeling much cooler than of late for many places, before slowly rising later, especially in the southeast.

UK Outlook for Saturday 18 Jul 2015 to Saturday 1 Aug 2015:

Many southern and central parts of the UK are likely to be mostly dry, often with fine, warm conditions. Towards the north and northwest there will be some cloudier conditions with rain at times, although even here some good periods of dry weather are expected. Temperatures are likely to be around average in the north, but in the south there may be spells of very warm weather for the time of year. These hot conditions bring a low risk of occasional thundery outbreaks, mainly for the southeast.
