Planning Outlook for all mountain areas from Thursday, 23rd May, 2013
Cold over the coming week. There will be freeze thaw cycles on higher Scottish summits, and on higher tops further south, temperatures often only a couple of degrees above freezing point. Total precipitation will be small, but there will be snow showers (often rain or hail on summits from S Scotland southwards), and occasionally, particularly in western Scotland, fronts may edge in bringing several hours of rain and low cloud. Generally summits will often be cloud free, and the visibility excellent.
