    At the time of writing, Saturday night is becoming very windy and wet in southern England and Wales due to a storm named Angus. Does it mean that the weather will calm down later? Yes, but only after another storm on Sunday night and Monday morning.

    Tonight, the weather will turn wet and windy and heavy rain will spread across England and Wales with hill snow in places and gale force winds will develop over southern areas. It will be cold for Scotland and Northern Ireland with showers in the west and lows of minus 5 Celsius. 

    On Sunday, there will be a wet and windy start for Wales, central and eastern England with outbreaks of heavy rain or hill snow in the north. Strong to gale force winds will affect southern and eastern England, especially in the morning. This rain and hill-snow will clear gradually north-east to leave sunny spells in the west. Scotland will stay manly dry with bright spells in places. It will be cold but largely fine in Northern Ireland.

    On Monday, another deep low pressure will move in from the south-west. It will be rather wet again with heavy rain and snow on high ground for England and Wales as well as strong winds across western parts. This rain will gradually move northwards during the day. It will stay dry for most areas but rain may edge into eastern parts of Northern Ireland and southern Scotland later. There will be patchy rain on Tuesday for many but it will be drier for north-west Scotland and south-east England. It will remain quite breezy or even windy, especially across coastal areas.

    On Wednesday, a cut-off low will develop over the Iberian Peninsula and the jet stream will move towards the north of the UK. High pressure is likely to develop in the Atlantic and drift over Scotland. From this position, it will block a low pressure over the Bay of Biscay that will tend to track northwards. This will bring a frontal system over south-west Britain. Meanwhile, dry conditions are expected for much of the rest of the country.

    This high pressure will remain quite slowly moving until Sunday at least, giving fairly dry conditions for much of the country with some sunshine at times.  A brisk easterly airflow will develop in southern England. On the whole, it will be a quieter end of the week. So for some, a calm will actually follow the storm(s).
