Snow for day after Boxing Day?

The models are showing another knife-edge situation for snow – similar to the ‘rain turning to snow’ event earlier this month. But there are a number of factors working against it this time round, at least for most of us who live between sea level and 30 metres.

The highest resolution model AROME shows snowfall rate but I would expect that only high ground (100m +) will see any accumulation

The low level supply of air off the continent is much milder this time round. Hamburg and northern Germany on the 9th was some 5C colder than currently.

The air pressure, crucial to bringing that snow line down lower, is forecast to be around 10mb higher this time.

And even if we see settling the soil temps, after the recent mild spell, are still 5C – 10C down to 10cm… Screen Shot 2017-12-26 at 11.46.19
