Planning Outlook
Thawing develops during Sunday, snow turning to rain, rising just above freezing toward highest tops in Scotland, whilst in England and Wales a more rapid and substantial thaw - beware unstable snowpack conditions, then becoming very wet underfoot where melting occurs. A complex and unsettled outlook next week, generally less cold than recently, but still often below freezing over Scottish mountains above 800-1000m, and at least intermittently below freezing over tops in England and Wales. A mix of snow and rain will fall, often snow on Scottish tops with fresh accumulations. Some showery days with hail. Wind will vary in speed and direction day-to-day, some lulls, but risk gales at times on hills.
