GENERAL SITUATION AND SYNOPSIS 06:00 UTC
Pressure is low and complex across the North Sea and southern Scandinavia. A strengthening NW’ly airflow over the Northern Isles will veer N’ly then NE’ly during the next 24 hours as low pressure moves further east and pressure builds from the northwest.
A NE’ly airflow will ease on Wednesday and Thursday as a weak anticyclone develops over the Norwegian Sea. An E’ly airflow is expected to freshen on Friday as the high drifts north and a depression tracks east across southern England.
With pressure forecast to be high to the northwest, a fresh NE’ly airflow is likely during the weekend over northeast Scotland, this easing early next week as a ridge moves east over the Northern Isles. By midweek present predictions suggest a strengthening S’ly airflow developing ahead of fronts driven east by Atlantic low pressure.
