A major weather episode promises to be in southern Europe. As of Monday, a heat dome will wrap Spain to head quickly to France. Even if it is short -lived, this heat wave looks really strong with very high temperatures. We worry about it because it could well break records and upset the daily life of the inhabitants.
The weather atmosphere in Spain
In Spain, we are witnessing the arrival of a dome of heat which invades the Iberian Peninsula. This phenomenon is driven by a anticyclonic backbone which increases temperatures spectacularly. The forecasts announce that the thermometer will regularly display between 40 and 42 ° C in several regions. Around the cities of Cordoba and Seville, it is even provided that temperatures reach 45 ° C. The most impacted regions will be Andalusia and Estremadure, where heat is likely to pose serious problems for residents and local infrastructure.
What awaits France
The heat will not stop at the Spanish borders and should touch the south of France from Thursday, August 8, carried by a persistent flow coming from the southwest. The temperature peak is planned for the following Friday, with values that can oscillate between 38 and 40 ° C in areas like the Aquitaine basin and the Toulouse Midi. Several departments could be placed under heat wave. In addition, the nights will remain hot, with record night temperatures, which may disturb the sleep of a lot of people.
The heat will not be satisfied with the south, it should gradually win the north over the days. Thus, over the week, she will also reach central regions, as well as Hauts-de-France towards the weekend. We could see temperatures of the order of 30 to 33 ° C in Île-de-France and in the Loire Valley, increasing the risk of a real heat wave if this heat persists three days in a row without the nights allowing to refresh themselves sufficiently.
Details on the climate and future forecasts
This episode stands out for its high intensity in the southwest of France, partly because of an omega blockage. According to the weather channel, the maximums could exceed the seasonal averages from 8 to 10 ° C, with a suffocating feeling in the agglomerations. In addition, Météo France recalls that, even if the month of August promises to be hot, we cannot take everything at the foot of the letter.
The anticyclone of Azores plays a decisive role by bringing a temperature increase in the South throughout the week. As of Monday, we are waiting for temperatures between 30 and 35 ° C in the south, while the North will experience some cloudy passages bringing a relative respite.
The coming days
The weather forecasts a gradual rise in temperatures all week, with risk of violent thunderstorms at the end of the period. On Tuesday, a last disruption will quickly cross the north, before a marked warming settled on Wednesday, with a blazing sun and temperatures up to 35 ° C in the southwest. From Thursday, there is a good chance that we are witnessing a sustainable heat wave, likely to reach scorching thresholds in several French regions.
