A fair amount of uncertainty at the start of this period as milder and more generally unsettled conditions towards the south and west try and extend further north and east. It is likely that northern and perhaps some eastern areas will start off cold with further overnight frosts and wintry showers in places. Indeed, northern Scotland may remain on the cold side, at least for the first few days of this period. Elsewhere, milder, or at least less cold weather than the preceding days, with areas of rain and stronger winds, this erratically spreading further north and east with time. Moving towards mid December and more generally unsettled and milder conditions look most probable with any colder interludes likely to be short-lived.

Conditions are most likely to be changeable through this period. Wetter and windier than average conditions are slightly more likely than normal, especially in the west and northwest. Temperatures are most likely to be near or above average overall, although this doesn't rule out some spells of cold weather and associated wintry hazards, though the chances of any prolonged spells of cold weather are low.
