After a snowy episode, a significant mild spell will be felt this weekend throughout France.
This Thursday, November 21, snow invaded France with the Caetano depression, just after the return of the cold. A beautiful white coat is still visible this Friday morning. Temperatures remain low, with negative temperatures reaching -3 degrees at daybreak. In the northeastern quarter, they are 3 to 4 degrees below seasonal norms. Beautiful clearings are expected during the day and will gradually widen over a large part of the territory.
For this weekend, big change in perspective. “A strong mild spell will occur,” announces The Weather Channel. From southern Aquitaine to the Alps, an improvement will be widely perceptible with mild weather and clearings. Conversely, in the northwest third, the sky will remain gray with wind and rain. However, temperatures will start to rise. The cold will still persist in the east. We expect between 1 and 12 degrees in the morning and between 3 and 17 degrees in the afternoon.
On Sunday, the mildness will go up another notch. 6 to 17 degrees are expected in the morning and 8 to 22°C in the afternoon. 20 degrees exceeded, The Weather Channel evokes “a little air of spring” to come, only a few days after the snow has fallen. In 48 hours, France will experience a spectacular jump in temperatures. While it is 5 degrees this Friday in Paris, 16 degrees are forecast for Sunday. While it is currently 2 degrees in Troyes, 15 degrees are announced 48 hours later and the 8 degrees in Toulouse this afternoon will become 17 on Sunday. An increase in temperatures of more than 10 degrees in the space of two days will therefore affect several locations.
This sudden change can be explained by the Icelandic Depression. When a current of cold air is present in this area at very high altitude, as it descends, it heats up and dries out, causing milder weather in the area. It will therefore chase away the polar air this weekend.
This trend will be confirmed at the start of next week, according to Météo-France. “Temperatures, well above seasonal norms at the start of the week, particularly in the southwest, should return to values close to average from the middle of the week,” specifies the specialized site.
