December's temperature will be around or below average for much of the time with just short milder intervals. Mid month seems like it will have the coldest spell before it turns mild again in time for Christmas.
Week 1 cooler than normal some wintry showers but no prolonged cold.
Week 2 Quite windy and wet before winds turn East later in the period.
Week 3 Very cold and frosty possibly some light snow.
Week 4 Mild and Unsettled for the Christmas period
