Planning Outlook
A switch to east-southeasterly winds by Sunday into early next week, some residual rain and high-level snow, but a drier and colder theme develops into the Christmas period and perhaps into the New Year, as high pressure builds to the north and northeast. An extensive cloud sheet will likely come in from the North Sea over many days with light snow showers or flurries likely, rain to lower slopes, but many areas dry. Best breaks in the west.
