Weather: End of DECEMBER and NEW YEAR, can the ‘RUSSIAN-SIBERIAN BEAR’ arrive, risk of SNOW to the PLAINS? The hypothesis
End of December: possible Russian cold snapImportant confirmations of the main meteorological models in sight for the last part of December arrive. In fact, the hypothesis of the irruption of one is corroborated russian icy air mass with Consequences directed as a wholeItaly. So let’s find out what to expect, tracing a general trend for the end of 2020, until New Year.
In the coming weeks, the Russian sector and part of the Scandinavian Peninsula will suffer a marked cooling with values of several degrees below zero. The map below clearly shows anegative anomaly in the temperature range, a clear sign that the infamous is forming “Russian-Siberian Anticyclone“, Or”Russian bear“as meteorology enthusiasts kindly call it. It is essentially ahigh thermal pressure, which is formed by the accumulation of cold air in the lower layers as a result of the strong and prolonged dispersion of the heat accumulated during the day during the cold season. L ‘hypothesis, confirmed for the moment by the US GFS model, is that part of this powerful icy bubble may slide first into Eastern Europe and then into Italy, giving way to a‘frost wave pretty intense between the end of 2020 and the new year.
CONSEQUENCES – If this trend is confirmed, it cannot be ruled out that a cyclonic vortex continually fueled by these cold Arctic forays, with the consequence of bringing back the snow to very low altitudes (locally on the plains) especially in the North Central.
Obviously, given the temporal distance, we invite caution, since the configuration could undergo important changes. But the plant seems to be there.
