A major change in conditions compared to the previous day with a mixture of heavy rain and strong winds, although perhaps turning more showery later. Temperature 17-18°C Wind strong - gale south becoming west-southwest during the afternoon




Low pressure over S UK with warmer air moving away eastwards and colder air moving down from the north

THURSDAY

Further rain at times due to a strong low pressure system moving across southern england, although the exact track is rather uncertain, so we have very low confidence in how much rain will fall. Temperature 15-17°C Wind fresh to strong west or west to southwest




Colder air covers the whole country by Friday

FRIDAY

Turning much colder and fresher and we see strong northerly winds pushing down across the country and over the island. Morning rain should give way to brighter conditions with occasional sunny spells during the afternoon. Temperature 12-13°C Wind fresh to strong north 19-38mph



There are a few hints that the storm system on thursday/friday could give much stronger winds than currently predicted, so we will update you in the coming days.
