A heat dome in France next week: will Brittany be affected?  – Brittany

After a certain respite at the end of the week, the high temperatures will be back in France next week. With a big difference compared to last week: they should be a little less bearable. The person responsible: a major anticyclone which will remain in France.

Its presence “will cause a flow from the southern sector from (this) Sunday, thus bringing up subtropical air over the country”, explains, on its site, La Chaîne Météo. “At the same time, a few thunderstorms will break out in a scattered way, making this heat heavy and humid, especially during the nights. From this Sunday, the maximum will oscillate between 25 and 30 ° C. With peaks at 37 ° C, felt, in the Landes.

Up to 40°C felt

Monday should be a little more breathable, before the installation of a real “heat dome” in France. This expression is used when the atmospheric situation is blocked by an anticyclone, leaving the warm air to stagnate on territories, such as a dome.

Tuesday, Wednesday and Thursday are shaping up to be “hot days”. “Up to 33°C in the South-West and between 25° and 30° locally going towards the North-East”, predicts La Chaîne Météo. That is five to ten degrees higher than normal for the season. Hot and sultry days in the city: “Due to the humidity, the feeling will be very heavy. It will approach 40°C in the Southwest. Thunderstorms cannot be ruled out. The nights will also be comparable to those of summer: the mercury should rise to 18-19°C in large cities.

“We could approach some heat records”

“In this context, we could approach some heat records for the month of May, especially in the Midi-Pyrénées region and towards the central regions (Bourges, Saint-Étienne, etc.), anticipate the meteorologists.

Hot weather, but not scorching: this threshold is established when the temperature exceeds 25.3°C for at least three consecutive days. While over the period, the national average temperature will remain around 22°C. Which, however, is not nothing, given the ongoing droughts.

Breathable in Brittany

If it will be very hot in the south of France, Brittany should be, to a lesser extent, affected by these high temperatures. Between 19°C and 25°C are expected in the region in the afternoon: cooler near the coast, warmer inland. Morbihan, Ille-et-Vilaine and the east of Côtes-d’Armor are the areas that will experience the highest values. Note that the mercury could reach 27 ° C in places in the territory of Brittany, Tuesday and Wednesday, according to the latest forecasts.
