@acsimpson: More likely the EEN editorial office hasn't been able to afford a new wall calendar since 2021.
This beast has been forecast for the last three weeks but has yet to materialize
It's related to a Sudden Stratocaster Warming event which is, apparently, currently in progress:
Note, however, that less sensationalist reporting carries a good many caveats:
The consequences of this warming will spread slowly into the troposphere and can, over time, disrupt the jet stream that influences our weather on the surface. A weakened jet stream can help in the development of large “blocking” areas of high pressure. Should high pressure build across Scandinavia, it can feed very cold polar air from the east into western Europe and towards the UK. However, it is important to note that not all SSW events are the same, and not all will lead to cold conditions in Europe. The eventual effects of such SSW events are not usually experienced until two to three weeks after they begin.
