Planning Outlook
Cooling in the night to Thursday, with sleet falling on highest Scottish peaks. A trough arriving on Thursday to Scotland brings another wet day on the Highlands with upland gales. England and Wales, although very windy and gusty, should get some sun between common showers, perhaps excluding Lake District and North Pennines, where clouds and rain still dominate. Damp, but generally much drier on Friday, some rain still in West and Northwest Highlands, in Brecon Beacons, Snowdonia and Peak District. Uncertain development further on, most likely fairly cold for the season. Chance for fine conditions during the weekend but unstable air may cause locally heavy showers or thunderstorms.
