L’high pressure in the Azores is becoming more and more prevalent throughout theWestern Europe and theNorthern Europewhere weather conditions are favoring rather stable. This pattern will tend to strengthen further in the coming days thanks to the acceleration of the jet stream close to Greenland and the Arctic Ocean, which will inevitably bend the anticyclone towards the Scandinaviaenveloping a good part of theCentral Western Europe.
It will be precisely the expansion ofhigh pressure towards Northern Europe to allow the arrival of one cold wave on Central-Southern Italy during this weekend and the start of next week. The only one semblance of winter in fact it will be found in the South and above middle-lower Adriaticwhere the snow will arrive at hilly altitudes, especially during Sunday and in the first part of Monday.
Moving further afield Nordwinter will be anything but present, except during the night hours, when the mercury column will slip below zero favoring frost e frosts. The days, however, will be much longer ESTABLISH and also warmerwith temperatures that could on several occasions exceed 10 °C during this weekend and the first half of next week. Subsequently, as the mid-Januarytemperatures could soar further across the country Central-Northeven reaching i 15-16 °C in central hours.
It will be exactly theanticyclone the great protagonist of second ten days of January throughout central-northern Italy and much of central-western Europe. In short, winter is giving itself a break prolonged pause not only on the northern regions, but also on the rest of the Old Continent.
Something will change in third ten days of January? The latest updates do not indicate any particular winter shocks even at this stage. It seems, in fact, that high pressure will continue to dominate the Mediterraneankeeping both disturbances and waves of frost dall’Est Europa.
As can be seen from the average of the scenarios of the American model GFShigh pressure will persistently invade the Mediterraneanpreventing the advance of very coldwhich will remain confined to theEast Europa and, at most, in Scandinavia. The presence of one jet stream too strong over the North Atlantic, linked to a short recompaction of the polar vortexwill be instrumental in keeping the frost away from Italy.
