Isle of Portland (Dorset) weather

Headline:

Any morning mist patches soon clearing, then it will be a bright day with plenty of sunny spells. Perhaps an isolated afternoon light shower is possible. Feeling warmer than of late, with light winds. Maximum temperature 23 °C.

Tonight:

Plenty of sunny spells ahead of dusk, then the cloud thickening from the west overnight. Perhaps a little light rain or drizzle developing towards the far west by dawn. Minimum temperature 9 °C.

Thursday:

A mostly dry day, with the best of the sunshine in the east. Generally cloudier in the west, with some coastal fog and drizzle possible later in the day. Warm. Maximum temperature 25 °C.

Outlook for Friday to Sunday:

A cloudy start Friday, then becoming warm with sunny spells. An increasing risk of heavy showers on Saturday, becoming rather humid. Drier Sunday and feeling cooler.

Early in this period, low pressure is likely to exist to the northwest or north of the UK, allowing areas of cloud and rain to spread across the UK from the west, though some more settled interludes are also likely, especially in the southeast. Breezy at times, with temperatures mainly near or below normal. Remaining changeable thereafter as weather systems to move across the country from the west, with northern and western areas typically wettest and a greater chance of dry conditions prevailing in the southeast. There is, however, a smaller chance for either unsettled weather to be more widely prevalent, or for a more quiescent period to develop across the south, especially later. Overall, temperatures will likely be near normal, but may feel cool in the west at times.

Through this period, there remains a slightly increased chance of more settled spells of weather developing at times, particularly in the south. However, there is still a substantial chance of other weather types too, with more changeable periods also likely. Through the period as a whole, drier than average conditions are more likely than wetter than average. Warmer than average conditions are also weakly favoured overall, with a slightly enhanced likelihood of short-lived hot spells.
