Planning Outlook

High pressure centred over Scotland will dominate the weather until later this week. Winds gradually ease over England and Wales, whilst almost calm across much of Scotland. It will be extensively dry. Frost in valleys and glens most night, plus areas of low-level fog. Higher terrain substantially frozen, although air temperature will be several degrees above freezing above an inversion. Toward next weekend, as the high weakens and moves south, rain bearing fronts and stronger winds will increasingly affect at least northern Britain. Temperatures likely to fluctuate with some periods of thaw, but possibly still often sub-zero at least on Scottish mountains during mid-December.
