Chertsey (Surrey) weather

Headline:

Low cloud spreading inland in the east. Clearer further west.

This Evening and Tonight:

Variable cloud this evening with the best of any cloud breaks in the west of the region. Low cloud is expected to roll inland from the east, giving some misty conditions. Probably staying dry. Light winds. Minimum temperature 7 °C.

Thursday:

Cloudy and dull start, mainly across eastern areas. Cloud thinning and breaking to give an afternoon of mostly bright spells. A fine evening, before low cloud spreads inland again overnight. Maximum temperature 17 °C.

Outlook for Friday to Sunday:

Cool and cloudy start Friday, then fine but with increasingly hazy sunshine. Variable cloud Saturday and Sunday with largely fine and dry conditions expected. Temperatures above average or warm.

Most likely starting off widely fine with sunny spells, following the clearance of early morning mist and fog. This most likely in the south, whilst in the north there's a greater chance of more cloud which may take some time to clear. There's a small chance that fine and very warm weather could extend right across the country over the following days, but it's more likely that cloud/rain in the northwest will sink southeast introducing more changeable and cooler conditions for a time mid-week. It then becomes roughly equal chances that we see a resumption of mainly fine and dry conditions versus a continuation of more changeable weather with a mixture of rain and drier interludes.

Forecast confidence is lower than average for this range, although fairly typical for late Spring. A typical mixture of drier and settled periods, and periods of wetter and more unsettled conditions, is on balance slightly more likely than predominantly unsettled or predominantly settled. Temperatures are likely to be around average overall, with a slightly increased chance of warm or hot spells. Any such spells could be accompanied by locally heavy showers and thunderstorms.
