Sub-tropical Moisture Plume Extends From Central Atlantic to Scotland

With a large vortex of low pressure dominating the North Atlantic and a huge high over Europe, Ireland and the Northern UK finds itself beneath a long fetched plume of moisture associated with a stalled frontal boundary which extends from the heart of the central Atlantic, all the way to Scotland. Incredibly, according to satellite imagery the cloud band is seen to extend some 4,000 miles from the UK all the way across the Atlantic to the Caribbean.

The fact this is stalled and the moisture extends, unbroken from the subtropics, means a lot of steady and persistent rainfall for Ireland, Northern Ireland and western Scotland over the next two days so be prepared for potential flooding. This has been highlighted since back last week given the setup and likelihood of the UK being trapped between weather systems.

Luckily for much of England it should be mainly dry with a mix of sun and cloud.

Across Ireland, NW Northern Ireland and western Scotland, winds will be strong and it is here, nearest the front, temperatures will be very mild even at night with lows merely falling to between 10-13C, by day, we could see 15C, keep in mind the source region of this flow.
