During Tuesday night a frontal band of heavier rain arrives from the west over Ireland. So, Wednesday will start wet and windy for Northern Ireland with fresh to strong southerly winds for coastal western Britain and through the Irish Sea during the morning. This will stir the gloomy murky on the deck at least. This waving frontal band is forecast to move across Northern Ireland and then Britain during the second half of Wednesday as an active cold front. Ahead of this there will be another quiet start again with mist and fog, light winds but some brightness over SE Britain and a cooler start for the E. The progress of this heavy rain has lower confidence for timing and positioning, but it looks to move over western Britain by Wednesday evening with heavy downpours, strong gusty winds and brings the risk of surface water flooding. There are a lot of fallen leaves about.
Colder, fresher clear air spreads across the UK from the Atlantic following the passage of the front with a brief ridge of high pressure. So, Thursday see a fine, sunny start after some blustery wet weather during the night.
However another low pressure will be getting closer from the Atlantic, this lurks south of Iceland but NW of the UK and will bring further wet and windy weather in from the west as a waving front also introduces rain from the south.
