hoochymamgu - long range forecast from the metoffice mentions the possibility of cold so you might be in luck!....
Wednesday 27th November - Friday 6th December
Wednesday looks set to be a continuation of the wet theme, though rain may become lighter and push away to the southeast of the UK later. Temperatures around average in the south, but beginning to turn colder in the North. Next weekend looks likely to be rather unsettled, with some sunny spells and showers, which could often be wintry, even to low ground in the north. Cold or rather cold in the north, with widespread frost and ice likely, but perhaps mild for a time in the far south and southwest. The following week looks set to remain cold for many, as the potential for wintry showers in the north continues and may spread to higher ground in the south. The best chance of dry weather in the south/southeast.
Saturday 7th - Saturday 21st December
The period is likely begin on the cold side for most regions, with snow showers at times in the north, and perhaps over high ground in the south. Widespread frosts and ice are likely to continue to be a hazard. There is likely to be change around mid-month to milder conditions, although the timing is very uncertain. This change will likely bring milder and wetter conditions across most parts of the UK, allowing temperatures to recover to around average, or perhaps slightly above. The wettest conditions are likely to be in the north and west, with an increased likelihood of drier spells in the south and south east. Colder interludes are still possible, mainly in the north.
