Most frequent western tops
Covering most higher slopes from dawn, but then rising and breaking toward higher tops as rain clears. Patches likely to come and go on tops around 700-800m, most often in western areas.

Planning Outlook
Southwesterly winds brings milder conditions into this weekend - lifting above freezing to tops in England and Wales with substantial thawing, and generally higher freezing levels in Scotland; periods of thawing to Munro summits will occur but also further snowfall and refreezing on higher terrain during the day-to-day variability of precipitation and freezing levels onward into early next week. Likely colder later next week, back below freezing on higher terrain for a run of days. Often windy with periods of upland gales. Some spells of heavy rain over all western hills and low cloud frequently covering the hills.
