UK: Atlantic low to be replaced by Scandinavia high this weekend?

A new week, same weather pattern with HP building in today providing a drier, less showery Tuesday only to get replaced by another incoming Atlantic system Wednesday. Tuesday night into Wednesday turns increasingly wet and windy, esp N/W Britain with potential S gales through the Irish Sea/North Channel along with high rain amounts for Cumbria, Dumfries and Galloway and Argyll.

Ahead of the front, it turns warmer thanks to a southerly flow of moist, continental air.

Towards the end of the week, high pressure will attempt to build over the UK thanks to a deepening low positioned over the open Atlantic. The uncertainty is incoming disturbances riding the northern flank of the building high and do they flirt or scrape the NW or pass over? With southerly winds and warmer, more humid air lifting north from the tropics, it should turn warmer.

At this moment in time and it remains a long way out still but there’s some good agreement with the models on a building Scandinavian high which shall shield the UK from the Atlantic through the upcoming weekend and on into next week but a cool, showery easterly could develop while systems to the west get held at bay.
