The air mass origin in the arctic that accompanies the second perturbation of January was tol spread rapidly over the territory, followed, starting from this evening, from the nucleus more sharply that will affect our regions not only during the day ofEpiphany, but also for most of the weekend, loosening the grip on Sunday. The winds the stormy northern will continue – as alleged by the meteorologists of the Weather.en – to convey cold air to our regions, especially towards those of the east are less protected from the alpine arc. It will be the air source is dry, which then will be enriched with moisture, passing over the Adriatic sea, the Ionian sea and the southern Tyrrhenian sea, creating the conditions for snowfall to quote unusually low even on Sicily. The peak of the cold is expected for the day of Saturday; in the following days, the bite of the frost will go down slowly. In Lombardy, as well as in the upper Piedmont and south Tyrol, some bows are currently carried by the wind that blows stormy in the Alps where it is snowing significantly. The snow at this time, in fact, are of interest to the ridges of the sectors most northern of the Alps and the gusts recorded have even reached peaks of 150 km/h in some alpine valleys. The snow flow is a phenomenon that could also occur in the tyrrhenian regions below the wind, the Apennines to the effect of the stormy current from the north that is investing Italy.
Saturday, January 7, in the first part of the day is still possible snowfalls intermittent up to the level of the sea in Abruzzo, Molise, Puglia, Basilicata, high ionic coast of Calabria, and between southern Calabria and north of Sicily. The tendency to the exhaustion of phenomena in the second part of the day, from Abruzzo, Molise and northern Puglia. In the night the snow could still affect only the southern Puglia. In the rest of the Country time quite sunny with increasing cloudiness in the morning on Liguria, the Tuscan coast and Sardinia. The northerly winds will begin to subside will, however, still moderate the strong on the middle Adriatic, to the South and on Sicily. The icy cold climate with frosts, intense and diffuse in the night and in the morning to the Centronord and locally, even in the South, and maximum, in the sunny areas, a little above zero. Between Friday and Saturday will be likely to days in ice (days in which the temperature in the afternoon does not exc eed the zero) in the areas affected by heavy snowfall including areas affected by the earthquake. The strong winds of the northern, with gusts up to 80-100 km/h, it will begin to subside in the North on the day of the Epiphany, and in the Center-South between Saturday and Sunday. The sensation of cold will be accentuated by strong winds due to the effect of wind chill (the wind chill), that is, the phenomenon by which, in the presence of wind, the sensation of the temperature perceived by the body turns out to be lower than the actual temperature of the air. The value of the wind chill is calculated knowing the values of the air temperature and the intensity of the wind. On Sunday you will burn off further inflow of cold air with the last of the phenomena of isolated, possible only in Apulia and in the north of Sicily, with the limit of the snowfalls on the rise. A tendency to an increase of cloudiness low but without precipitation in the medium Tyrrhenian sea and Sardinia. The rain larger unable to resist, to the North. At night and early in the morning, the intense cold, a little bit everywhere. Maximum rise slightly.
The civil Protection has already called on citizens to prepare themselves, by restricting their movements, especially in those regions where snow is uncommon.
