Planning Outlook
Cold east or southeasterly winds prevail, but less cold widely over the weekend as freezing level lifts somewhat from the south, rising just above freezing point in Scotland toward 1000m. Colder air then likely returns from east next week. Further snowfalls mostly over eastern hills in Scotland, occasionally hills in England & Wales, mixed with rain here. Indications of less precipitation and lower wind speeds for periods during next week. Highest cloud breaks west & northwest Scotland, where terrain will be very dry toward west coast.
