Planning Outlook
A slow-moving weather pattern onward into early next week with chilly air in place across the British Isles, mountains staying near to freezing point in Scotland, typically just above freezing to high tops in England and Wales for a few days. Some weak fronts try to push in from the west bringing occasional rain and hill snow, amounts generally small. High pressure around Scandinavia is likely to dominate the patterns into the later stages of January, with colder air trying to push in from the east, much mountain terrain will be frozen. Occasional snow likely, generally driest in the northwest.
