Portishead (North Somerset) weather

Headline:

Mostly fine at first. Wet and windy later this week.

This Evening and Tonight:

It will be dry through the evening and overnight. It looks fairly cloudy at times, though it will turn chilly under the clearer slots with the odd fog patch forming, particularly across parts of Somerset, Dorset and Wiltshire. Minimum temperature 8 °C.

Wednesday:

A fine day is expected on Wednesday, with bright or sunny spells developing after a chilly and locally rather murky start to the morning. A warm feel in light winds. Maximum temperature 18 °C.

Outlook for Thursday to Saturday:

Thursday will be mostly dry, though rather cloudy and breezy. Wet and windy overnight, then unsettled on Friday and Saturday with rain at times, and some strong winds.

A deep low will probably be clearing to the east or northeast of the UK at the start of this period, leaving the UK in a broadly westerly pattern for the following few days. Within this we are likely to see further spells of rain and strong winds at times, these more likely affecting northern and northwestern areas, but all parts of the UK could see some rain from time to time. Towards mid-month, there is a signal, albeit a weak one, for pressure to build in the vicinity of the UK, with a better chance of more areas seeing some longer drier interludes. On the whole temperatures look to be fairly close to average, though some chilly nights are to be expected at times.

The latter half of October will probably see a transition to more widely unsettled conditions once more. Whether this takes the form of successive depressions steaming in from the Atlantic or a rather slower evolving weather pattern remains to be seen, but there is a greater chance of more places seeing more frequent spells of rain and possibly strong winds. Temperatures probably remaining close to average overall, but with a reduced incidence of chilly nights compared to earlier in the month.
