Planning Outlook

A settled week ahead as high pressure resides toward the north. Easterly winds will prevail, strongest for Wales and the southern Pennines. Largely dry weather, whilst variable cloud will be drawn in from the North Sea, at times some light showers in eastern areas. Best chance for inversion conditions will be on higher tops in Scotland, emerging above cloud at times. Sunshine typically best toward western coasts. Temperatures mostly above freezing on high terrain, but some frost overnight in glens and some upland hollows; then cooler toward the weekend on tops. Quiet weather also likely as next weekend begins, perhaps further ahead, though a mixed Atlantic influence may return to Scotland.
