Planning Outlook
A notably chilly outlook for May into the weekend and early next week, with higher Scottish mountains almost continuously below freezing point possibly onward through much of next week as northwesterly air prevails. After a warmer end to this week, higher tops in England and Wales also dropping intermittently to freezing point from the weekend onward. Wind-speed varying day-to-day, but prepare for often considerable chill-factor on all mountains. Some frost overnight into valleys when skies are clear. Broadly showery through mid-May, plus some fronts bringing persistent rain most common in northwestern Scotland, often falling as snow on mountain tops, sometimes to below 600m. Drier intervals too, some days with fewer showers and broken cloud lifting above the summits, varying locally day-to-day.
