Temperatures drop on Friday, especially in the Adriatic and the south

VERY LOW TEMPERATURES UNTIL THURSDAY, THEN SIGNIFICANT DROP IN THERMAL TEMPERATURES – Until Thursday, Italy will be affected by a mid-southwest flow characterized by decidedly warm air masses of direct subtropical extraction. Therefore, we will have to face temperatures much higher than the averages of the season, especially with regard to the maximums: in fact, in sunny areas it can easily reach 18-20°C, but with peaks of more than 23-24°C. C in the South and in the Major Islands. Definitely mild climate (relative to the current period) even at altitude, both in the Alps and the Apennines, where temperatures are above average, sometimes between 8 and 10 °C, as highlighted on the map below , which shows the thermal anomalies at about 1500 m altitude. the sea level .

Thermal anomalies around 1,500 m altitude during these hours

It is evident that at night the thermal inversions and nocturnal radiation will continue to favor a fairly cold climate, especially in the narrowest valleys and in the absence of wind with clear skies, but during the day the climate will continue to have a practically spring-like flavor (except in areas local). exceptions).

THERMAL DOWN FRIDAY 17 – The passage of a cold front linked to an outbreak of arctic air, whose main objective will be Central-Eastern Europe, will also favor a reduction in temperatures in Italy. The drop in temperatures will be more decisive in the Adriatic area and in the south, where even between 6 and 8°C could be lost. Compared to these days, if not 8-10°C on the Adriatic slope of the Apennines (where there may also be some snowfall at medium altitudes). Precisely in these sectors the thermal values should also fall a few degrees below the average, all accompanied by sometimes sustained/strong winds coming from the northern quadrants. The thermal decrease, however, is less noticeable, although expected, in the northwest and on the Tyrrhenian slope. (except for Sicily, which is more exposed to flows from the North).

Thermal anomalies are expected on Friday at about 1,500 m altitude

IT WILL LAST A SHORT TIME, NEW THERMAL RISE DURING THE WEEKEND – After a physiologically cool Saturday morning, it is most likely that the northerly flow will be progressively replaced by new very mild air masses of subtropical extraction with the consequent general increase in temperature to above-average values. Updates will follow.
