GENERAL SITUATION AND SYNOPSIS 06:00 UTC
A flat ridge of high pressure extends northwards across the UK. Pressure is low to the north with a cool, strong and showery W’ly airflow over the Northern Isles. Though this should ease later today as a small low tracks east across mainland Scotland it will strengthen again later tonight as the low moves away.
A strong W’ly airflow on Tuesday will veer NW’ly as low pressure to the north transfers towards Scandinavia. This will then ease through Thursday as a ridge of high pressure edges in from the west.
Though an Atlantic front is forecast to move east towards the British Isles later on Friday this may well weaken as it comes up against high pressure. Current predictions suggest high pressure could persist over next weekend and in to the start of the following week.
