Sunday
Mainly dry conditions should prevail across most areas through the course of Sunday, but especially across many northern and western areas of the UK where bright or sunny spells are forecast. Locally heavy showers or thunderstorms may develop across southern counties of England during the afternoon. Warm or very warm. Highs 16C to 24C.
Sunday Night
Localised heavy and perhaps thundery showers across more southern counties of England fading away and then many areas having a dry night on Sunday night with clear spells and variable cloud. Some local mist and fog patches possible, especially where any daytime showers have been. Cool north, mild south. Lows 7C to 14C.
Monday
Into Monday and further sunshine and scattered showers are possible. Again some southern areas of England could be primary risk, but perhaps also across parts of Scotland and N England by this point as well. In-between still plenty of dry weather with sunny spells but turning cooler and fresher from the north. Highs 15C to 21C.
Tuesday
The risk of showers is forecast to continue, again especially across England and Wales. However, there is some forecast evidence to suggest that more of an Atlantic influence to the weather may well begin to develop and this could lead to a greater risk of rain or showers arriving from the west in association with low pressure systems moving into the UK off the N Atlantic to bring about, potentially, a more protracted period of unsettled weather. Near average temperatures but turning cooler. Highs, 13C to 20C.
