Weather: Heatwave and Thunderstorms this Weekend

According to the Weather Channel, the weekend will be marked by an intense heatwave, the mercury may exceed 36 ° C from south-west to east-central and 33 ° C in Paris. Severe thunderstorms are expected to erupt in the west.

It will be very hot this weekend. According to the Weather Channel , in the morning the minimum will be between 17 and 23 ° C. In the afternoon, the maximum will range from 30 ° C near the ocean to 36 ° C from south-west to east-central and 33 ° C in Paris. The feeling will be heavier because of the humidity and lack of wind: the north-east wind that was present all week will not be there.


As for the sky, Saturday the sun will shine in an overwhelming atmosphere because of the heat in the afternoon, especially in the south. During the afternoon and in the evening, thunderstorms will break out on the Atlantic arc and go up from the southwest to Normandy. They will be violent. On Sunday, the weather will remain stormy in the northwest and near the Atlantic in a heavy atmosphere. The sky will be veiled from the Pyrenees to the coasts of the Channel. East of the Rhone and Saone, it is a sun of lead which is still awaited with some storms in mountain at the end of the day.
The Weather Channel * recalls that a heat wave is defined by a period of very hot weather (with temperatures generally 5 ° C above average, for at least 3 days and 3 nights in a row). These summers have been characterized by scorching episodes sometimes marked and durable, especially in 2015. Last year, France had already experienced a strong heat wave in June.

First heatwave in France

According to the seasonal forecasts, the coming summer looks rather standard, namely in the seasonal norms, but with a strong shade between the month of July, rather nice and hot, and the month of August, more gloomy and more humid. In this context, the potential risk of heatwave is more focused on July, while the month of August would be less exposed. But this risk seems rather low because the global temperatures expected in July should be only 0.5 ° C to 1 ° C above average.

Another parameter limits the risk of heat wave: soil moisture. Studies have shown that very wet soils, resulting from a rainy spring as was the case this year, limit the rise in maximum temperatures as well as the duration of heatwaves. We should be this summer in this configuration rather reassuring about it.
