After the snow comes the heat: from when and where

After the snow of Valentine’s Day, the heat arrives, with February April, the month of February that disguises itself from April with an anticipation of spring from North to South. A real turnaround is expected with temperature differences typical of the continental areas of central-eastern Europe. In the Po valley between Thursday and Friday, maximums will return to 15 ° C, with peaks in the north-west of 20-22 ° C; in the center-south peaks of 20 ° C, also between Tuscany and Lazio and up to the capital. It is likely that due to global warming, the temperature in Milan or Turin was unable to drop to 0 ° C during the heaviest rainfall: we had snow mixed with rain, sleet, very weak damp flakes but the rooting was almost nil . Without global warming (in Italy we are around + 1.5 ° C compared to the pre-industrial era, official ISPRA data) we would have had 10/15 cm of snow in the city. In short, in 1880 Garibaldi visiting Milan would have found streets covered by a soft white mantle, with the same perturbation. temperatures that will bring an anomaly of 10 ° C to 850 hPa, at about 1500 meters: this anomaly will quickly melt some snow on the mountains, but the ski slopes will be perfect for weeks after the 50 cm of fresh snow fallen in the last 2 days. The melted snow will still be manna from heaven for the northern water tables, severely thirsty after the drought of the winter of 2021-2022. only in the next few hours in the extreme South with heavy showers: for the rest, high pressure will return, dominant, protagonist over most of Western Europe and February will begin, a long period with temperatures more typical of April than of the month current.
