Cold Front Pushing All the Air Back Down in the Caribbean

The weather over the next week looks rather quiet, often fair but sometimes grey and cloudy. It will be predominantly dry and begin to feel colder. As there is a shift back to opening windows, attempting to sit outside or just waiting in the queue for a booster jab, it will be more about how the weather feels, in the coming days.

The high builds in from the south, pushing away the lingering weather fronts which have brought a lot of rain to NW Scotland. Today a cold front pushes down from the north, becomes stationary and is then shoved northwards early Thursday as the flow shifts. A warm front by then with some milder air for the northwest of the UK.  By the weekend, as the high nudges northwards, southeast Britain will begin to catch a cooler flow off the continent, which could turn colder by the middle of next week.

This high pressure becomes a block against any other weather system. It gets comfortable, has an initial wriggle about in its atmospheric armchair and then stays put, like a slightly inebriated relative in front of the Christmas telly. It forces the Jetstream away, to the north here and the usual incoming low pressures are steered to Iceland and Scandinavia. It is known as an Omega block because of its shape. Omega being the last letter of the Greek alphabet and one we don't want to be hearing about in any other circumstances.

At times the cloud will lower and be thick enough to bring dampness, even drizzle, that misty drizzle that can creep up over 15 minutes to soak you. Coastal areas look more likely.

Fog

Another issue for how the day will feel will be fog. Where this form and lingers the day will be grey and cold. It will rely on clearing skies so more many parts the murkiness will be different, not dangerous and on the deck. Just gloomy low cloud. There will be breaks in the cloud tonight for north Wales, through the Midlands to Norfolk, into northern England, southern Scotland and Northern Ireland. So, fog could appear here. More chance for Thursday morning of any fog lingering. Lighter winds, slightly colder.

Rain

The ongoing warm conveyor of rain into NW Scotland will fade by Friday. It waves about a bit as the front moves south then north, allowing more cloud and patchy rain over Northern Ireland, Cumbria and southwest Scotland today. Then through Wednesday night, the rain moves northwards over west coast Scotland. Otherwise, it looks dry.

Weekend plans

It won't be windy for most of the UK although more of a mild westerly wind for the Northern Isles and at times a noticeable breeze from the east for English Channel coasts. There looks to be more chance of fog and frost particularly for northern Britain by the weekend. Fine for a walk, ride or run but take your gloves and woolly hat.
