Planning Outlook

All mountain areas of Britain from Saturday 1st November 2014

Windy on Saturday with a band of rain spreading east in the afternoon. Early next week will see a progressive drop in temperature on the summits; still showers and for some, several hours of constant rain. By Tuesday, some areas dry, and on Wednesday and perhaps Thursday, extensively dry with the wind having dropping. Cold enough for valley frost, and higher Scottish summits sub-freezing. Probably milder as further constant rain followed by showers (mainly west) follows in off the Atlantic later in the week.
