GENERAL SITUATION AND SYNOPSIS 06:00 UTC 02/09/2015
With pressure high to the west and a depression over southern Scandinavia a strong N値y airflow covers northeast Scotland.
The strong, cool N値y airflow will persist through Thursday, but temporarily ease on Friday as a frontal system slips south across the Northern Isles. A ridge will approach from the west during the weekend, maintaining a fresh NW値y airflow, with a weak front slipping round the edge of the high to affect Orkney and Shetland on Sunday.
After the weekend the airflow will slacken as a ridge moves east across Scotland. Present forecasts suggest the following week may start with a moderate SW値y airflow as the ridge declines but current predictions suggest this strengthening later as Atlantic low pressure drives fronts east over Scotland.
