While temperatures have cooled down for some time in Francethis trend should continue in the coming days, if we are to believe the forecasts of Meteo France. In fact, temperatures will drop so much by the end of the week that snowfall is expected at very low altitudes in the east of the country, from Friday November 24, 2023. “It will start Friday evening at 500-600 meters and it will drop overnight to 300-400 meters“, said forecaster Pascal de Guélis at the microphone of BFMTV. However, it also specifies that the precipitation will begin to fade during the night of Friday November 24 to Saturday November 25, 2023. This could thus prevent the snow from remaining on the ground below 500 meters above sea level. The snowfall announced by Météo France should occur over a part of France which extends from Alsace to the south of the Jura, via the Vosges.
The drop in temperatures should allow the appearance of snowfall
However, uncertainties are to be expected in the Alps during the weekend. For the moment, the data put forward by the French meteorological agency remains “still a little to confirm”, because they were recorded more than two days before the arrival of these potential snowfalls, as Pascal de Guélis pointed out. In addition, according to Météo France, snow could also fall on the territory during the night of Saturday November 25 to Sunday November 26, 2023, at conditions that temperatures are sufficiently low at that time. As a reminder, snow forms when the water vapor contained within the clouds transforms into ice crystals under the effect of negative temperatures. The crystals in question will then attach to volatile particles such as dust, sand or ash, before gathering into flakes. Snow falls when these famous flakes are heavy enough to overcome air resistance. The sky must therefore be cloudy and the mercury must indicate a figure less than or equal to 0°C for snow precipitation to occur.
