A complete change is taking place in the skies of France. Despite above normal temperatures these days, the weather will change dramatically next week and turn into winter. There are two elements that characterize it: a drop in temperature and the possibility of snowfall.
The thermometer drop will begin at the weekend. This will accelerate over the next week. The reason lies in the complete reversal of the origin of air masses in France. The Sahara-origin current currently hitting France will be replaced by a dominant current originating from the Arctic.
The result of this situation is a decrease in the maximum temperature of 10°C to 15°C in the afternoon. Frosts, so far rare on the plains, will be frequent. This map from Météo France on the afternoon of Friday 21 November speaks for itself. Except near the Mediterranean and at Finistère, the meter will only display one number, often less than 5.
Although the reliability of these estimates remains to be refined, the trend is clear and increasingly confirmed. The country will then experience temperatures lower than normal seasonal temperatures, namely around 5°C to 7°C. The values will be winter in nature and will barely reach January values. The contrast will look amazing when compared to the current mild situation.
Almost widespread frost
At nightfall and dawn, thermometers will struggle to stay positive in urban areas, as shown by this comparison map between this Friday and next Friday, produced by The Weather Channel. Outside the city, frost will be almost widespread.

“On the other hand, the late November cold record should not be broken because this situation is quite classic of this season,” explains the Météo-villes website. “Let’s also note that these currents are maritime polar currents and not continental currents… Which makes a big difference! Because the influence of the sea weakens the cold temperatures,” wrote the special media.
This cooling should also be accompanied by snowfall in the mountains. Snowflakes may fall to the lowlands or even to the plains in the eastern part of the country. The odds are likely increasing, but there is still too much uncertainty to be certain.

After all, people living in cities or plains were not expected to be able to build snowmen. The ground won’t be cold enough to hold the snow. And the number may be too low.
After this period, the first trend is that temperatures remain low in the season, but will increase slightly. The end of the month can be very wet.
