Planning Outlook

A mixed southwesterly weather pattern prevails. Often windy, especially Scotland. Fronts coming in from the Atlantic bringing periods of rain most frequently in west and northwest Scotland. Small amounts of rain reaching eastern Scotland, more often dry. Patchier and less frequent rain for western England and Wales - higher pressure building for periods to give drier and warmer weather here. Low cloud often shrouding western tops, sometimes to lower elevations near coasts, higher cloud bases eastwards with better breaks.
