Planning Outlook

A ridge of high pressure produces a better day on Tuesday. Midweek onward, southwesterly winds will bring further rain from time to time, lowest cloud over western mountains. Temperatures near or a little lower than normal on the hills. Pressure tending to build from the south toward next weekend bringing drier and warmer conditions more widely. Southwest breezes toward northwest Scotland may continue to bring frequent cloud and a little rain at times here.
