Weather: All DECEMBER at risk of FROST and SNOW! The trend from IMMACULATE to CHRISTMAS inclusive is CLAMOROUS
Latest news for DecemberDecember, confirmed the start with the risk of frost and snow at least until the Immaculate Conception. This is the most interesting news concerning thebeginning of next month which could reserve decidedly winter weather conditions, with snowfalls at very low altitudes. But the surprises don’t end there, on the contrary: the trend for the following weeks for a Christmas is nothing short of sensational: one is coming big news.
The general winter, therefore, knocks on the doors of Italy and already in the course of early December will have its effects felt in many regions, with a lot of cold e temperatures down to below climatic averages.
To better understand the expected evolution we must, as usual, take a look at the picture European where it is clear that from the start of next month the rise in high pressure towards Greenland and Iceland will provoke a response serious breakthrough of arctic air about Europe and our country. Here then is that in the course of next week i snowflakes they could go down at very low altitude especially in the Central South. Much will depend on the intensity of the precipitation and the position in which the minimum depression will form.
And that’s not all. Just in conjunction with the fasta ofImmaculate, from 7 December onwards, Italy could be hit by awave of frost of yesteryear with the possible return of the name up to plains in the North and at very low altitudes in the Center South. In fact, at first temperatures should drop further due to the arrival of icy currents from Russia (-15 ° C at 850 hPa, about 1500 meters above sea level), then the entrance of a fast disruption from the West it could trigger snowfall in the plain.
The trend for the following weeks, up to Christmas is quite interesting and sees aalternation between anticyclonic phases and abrupt polar blitz with the return of bad weather a bit like what happened in this one “strange“ Autumn. The reason is to be found in massive meridian exchanges: i.e. on the one hand we will have the rise of the high pressure of the Azores towards Greenland (from South to North), on the other hand an area of low pressure linked to the Polar Vortex in extension towards Europe (from North to South) .
Italy would therefore find itself right in the middle of battlefield, with short dry and sunny breaks interrupted by rather cold and unstable air masses downhill from North Pole and from Russia, with temperatures below the climatic averages. Precipitation could be frequent, with the risk of snowfall up to very low altitudes.
In short, it is not excluded that what already happened in 2020 may be repeated, with two whitewashed also on the plains in December.
We will keep you posted.
