France Braces for Potential Fifth Heatwave as Temperatures Soar

France is anticipating a new wave of intense heat starting Saturday, with meteorologists warning it could be the fifth heatwave of the summer. La Chaîne Météo forecasts that a combination of a powerful anticyclone settling over Europe and a flow of subtropical air will bring prolonged high temperatures lasting until the end of next week.

Temperatures will again exceed 30°C in many regions, with 35 to 38°C, or even more in the south.

Temperatures are expected to climb above 30°C across many regions this weekend, potentially reaching 35-38°C, and even higher in southern areas. This significant increase, often 5-10°C above seasonal norms, is attributed to the subtropical air mass being channeled into France from the Iberian Peninsula and North Africa. The intense sunshine and very dry ground conditions will further exacerbate the heat.

This type of situation durably blocks Atlantic disturbances and favors durably dry and very sunny weather.

Forecasters predict that this heat could persist for much of the following week. While localized thunderstorms might occur on Sunday, they are unlikely to disrupt the dominance of high-pressure systems. The anticipated 'omega block' weather pattern, where high-pressure systems remain stationary for days, will likely prevent Atlantic disturbances from reaching France, ensuring continued dry and sunny weather alongside the extreme heat.

This advection of hot air combined with strong sunshine and very dry soils will favor a new rapid rise in temperatures.
