A cold snap is on the way for the UK as high pressure over Scandinavia strengthens, creating a blocked weather pattern that will bring chilly easterly winds. This type of weather setup means conditions will stay largely the same for an extended period, with colder and drier air moving in.
While easterly winds in winter can sometimes bring extreme cold and heavy snow, like the Beast from the East in 2018, that’s not the case this time. The air over the Baltic States and Russia, where this cold is coming from, is actually 5°C to 10°C warmer than usual for this time of year. Plus, the wind isn’t coming directly from the east, which takes some of the edge off the cold.
