In the first part of this period, many areas of the UK are expected to see periods of rain or showers. Some of these showers will be heavy and thundery, with the greatest chance of thunderstorms in the southeast. Along with this will be a fair amount of low cloud in the east at times, with spells of coastal fog, but also temperatures generally above average for the time of year. Overall, northwestern parts of the UK are likely to be driest and sunniest.
Through the second week, temperatures will return closer to normal, perhaps dipping back below average, but it will also tend to turn gradually drier and more settled, with changeable conditions most likely to hang on longest in the south and southeast.
