Planning Outlook
West to southwesterly winds prevail during the week ahead as areas of low pressure move toward northwest Scotland whilst ridges of higher pressure occasionally nudge across southern Britain. Sustained gales over the mountains, only brief lulls. Temperatures will fluctuate above and below freezing on higher Scottish mountains, with periods of thaw and refreezing. England and Wales generally above freezing to tops with a substantial thaw of most upland snow. Frequent rainfall, often heavy over western mountains, at times showery with hail, some snow on Scottish Munros. The final days of February favour colder northwesterly air and a drop of freezing level.
