The way I see things developing is like this..we get the cold northerly around new years day probably lasting 2 or 3 days and with the threat of snow for some particularly in Scotland.as we approach midweek it turns milder with the high moving southeastward, a northwesterly wind.during the latter part of week we see a stronger ridge developing in the Atlantic initially pushing up to Greenland to allow another cold northerly to develop. What happens after this is crucial, we ideally want to see the high drift east then north, rather then east then south.I believe the latter will happen sadly which means the deep cold will escape us and Germany France and northern Spain may well see the bitter temperatures! So as I said where the high drifts later next week is crucial in terms of whether we see deep cold,or something just below average...I do hope I am wrong and we see the deep cold move westward towards us,we shall see. ☺
