Planning Outlook
As a series of deep Atlantic lows pass north of or across Britain, rainfall be become high particularly on western mountains together with frequent upland gales and low cloud. In Scotland, temperatures on the Munros will sometimes be below freezing point, but fresh snow transient, whereas elsewhere, snow rare, if any.
