    UK forecast for the next 5 days

    Heavy, thundery showers in south easing. Many places dry overnight.

    This Evening and Tonight:

    Heavy, thundery showers across southern England easing this evening. Overnight, many parts dry, but cloud will gradually spread into the far northwest bringing outbreaks of rain. Low cloud, mist and hill fog will also return across central and eastern parts.

    Saturday:

    Fine, dry and warm for most, locally hot in southeast England. However cloud and rain will continue to move into northwestern parts, whilst the odd heavy shower is likely elsewhere.

    Cooler, cloudier and breezier Sunday with showery rain spreading southeastwards. Sunshine and showers Monday, a risk of thunder in the south. Tuesday, rain in the northwest, dry and bright elsewhere.

    Outlook for the UK over the next 6-30 days

    UK Outlook for Wednesday 30 Jul 2014 to Friday 8 Aug 2014:

    Many parts will be dry and fine to start this period, although rain or showers look likely to affect the north where it will be cloudier and breezier, with isolated showers in the south. Temperatures should vary from around average in the north to above average in the south, where it may be locally very warm. The start of August looks likely to bring a transition towards less settled conditions, with rain or showers in the north becoming more widespread. However, it will remain on the warm side, especially across the south where the best of any drier, brighter weather is most probable. The weather looks broadly similar for the following week, although there are indications that drier, sunnier periods in the south may become more prevalent.

    UK Outlook for Saturday 9 Aug 2014 to Saturday 23 Aug 2014:

    There is greater than average uncertainty concerning the weather through this period. Currently, generally unsettled conditions are likely to continue through the start of this period in the north with cloudy spells and sporadic outbreaks of rain, while the best of the drier, brighter conditions will be in the south and east. Temperatures should remain above average for southeastern parts, but near normal elsewhere.
