Winter is set to arrive in style on Thursday as Arctic air pushes in across the UK to bring the coldest spell of weather we’ve experienced in December since the record breaking December of 2010.
Initially a deep area of low pressure will cross over or to the north of Scotland bringing a spell of wet and windy weather across the UK but in behind we will start to pull a N’ly flow in, which will bring air down from the Arctic and along with it the risk of very cold temperatures, ice, frost and snow. This cold blast of Arctic air is shown very nicely below (blue colours).
Another way to view this cold air is via a temperature anomaly chart. Using this chart we can see that the cold pool doesn’t really shift a great deal, meaning the cold air is likely to stick around with only brief milder interludes possible, if at all.
With this cold air likely to persist then our attention turns to the risk of snow, which is likely to be a factor at some point in the next week, most likely from the latter stages of the weekend onward, with snow showers likely beforehand for north facing areas as well as eastern areas of the UK. This risk will be monitored very closely in the next day or so but scenarios like this below will be possible over the next week with a very real risk of disruption at times.
As ever we’ll keep you updated with the very latest so keep checking our pages for further updates.
