Planning Outlook

Notably chilly across the hills for this time of year during the week ahead as air from the north-northwest prevails. Frequently near or below freezing over Scottish Munros, and at times dropping to freezing on high tops in England and Wales. Wind speed will vary, but increasing at times to gale force on hills, giving significant chill factor. Broadly showery, heavy bursts with hail and thunder in places, also often falling as snow on higher mountains, at least in Scotland, intermittently elsewhere. Some more persistent precipitation especially northwest Scotland. Also some drier windows - varying locally day-to-day - away from showers cloud will lift above hills and visibility will be very good.
