Wild winds for the west midweek with Atlantic rain after a quiet start

High pressure has brought a steady, quiet spell of weather which continues into the start of this week. However, it will be all change mid-week as two low pressure speed in from the Atlantic and bring wet and very windy weather from the west. Even potentially stormy conditions, so some tethering and tidying might be necessary.

Today there will be a good deal of cloud over the UK with a light westerly breeze. Southern Britain has had a clearer start with a frost overnight so cold here this morning. Temperatures will reach 8 to 11C, still feeling cool under the grey skies. Southern Britain should manage more sunny spells this morning and that sunshine lasts into the afternoon for SW England and Wales, particularly in the south. There are a set of messy fronts which move mainly over Northern Ireland, Scotland and northern England but at times affecting north Wales and the Midlands, even East Anglia today with outbreaks of rain and thicker cloud.

Further bands of low cloud and rain bring a damp night to Northern Ireland and then by dawn, rain over western Scotland, NW England and Wales, away from the south. Ahead of this, there will be clear skies over SW Britain with a frost during the night and a cold start for SE Britain on Tuesday,

Again, southern England sees the best of the weather with bright or sunny spells. Northern Scotland and at times eastern England will also see the sun breaking through. Temperatures will generally be around 10C, up to 13C in London but the SW then southerly breeze will pick during the day. A sign of the first low pressure heading in from the Atlantic.

By Tuesday evening the low centre will be to the NW of Scotland with strong southerly winds and gales for coastal western Britain, around Northern Ireland and even severe gales for the Western Isles and may lead to disruption.

“Southerly gale or severe gales are expected for a few hours during Tuesday evening bringing gusts of 65 to 75 mph.” Met Office Yellow warning for wind.

The strengthening Jetstream will throw two rapidly deepening lows our way midweek

During Tuesday night the rain works its way across the UK. Blustery winds with wild conditions for the far NW but an improvement for Northern Ireland and Scotland by Wednesday morning when it will be briefly clearer and cooler and much less windy. That is bout 1. For England and Wales, the day starts off windy and wet but milder. Soon enough the frontal bands from the second low pressure arrive with more rain over western Britain and Northern Ireland. The southwesterly winds pick up again with mild air extending up through the UK midday before the cold front swings through bringing some heavy rain.

It’s all quite fast-moving and dynamic and during Wednesday night we get bout 2 of the strong winds and gales. There could again be severe gales for exposed parts and there will be high gusts inland. Overnight it will be Wales and SW England bearing the brunt of the wild winds, also through the Irish Sea and the English Channel. There will be squally showers following the fronts in colder air and with a fresh to strong westerly wind persisting on Thursday, it will feel cold. Gales again in exposure. The showers will take on a more wintry tinge through the day with snow later Thursday into the weekend for hills and mountains of Northern Ireland, northern Britain and Wales.

It really will be most different from the quiet weather we have been seeing. Bands of rain from the west with some high totals over the hills of western Britain and strengthening winds with gales, even severe gales for exposed western parts.
