If we thought that the drop in temperatures that we experienced this weekend was going to be something lasting, the truth is that we were completely wrong, since temperatures are about to rise again in a good part of the peninsula. Something that anticipates a possible new heat wave, which would be the fourth we have experienced this summer.
The AEMET notice. Through your X account, the public body made it clear that “the heat returns very intense to most of the country, especially starting Tuesday.” He even goes further by pointing out that, with the data we have on the table, this month of July would tie as the warmest month since there are records, along with July 2022.
Now, the culprit for this increase in temperatures would be an intrusion of very warm air that would enter the Iberian Peninsula in the next few hours and that would form a true “heat dome” that would trigger the thermometers.
What is to come. To understand why temperatures are going to rise so quickly, you have to look to North Africa. The situation What meteorologists predictlike Samuel Biener in Meteored, is due to the strengthening of a subtropical anticyclonic ridge that will remain stationary over our geography.
This configuration creates this ‘heat dome’ that acts as an immense high-pressure lid that pushes hot air downward, trapping it and compressing it against the surface. The result is that the environment overheats day after day without the possibility of ventilation and, to further complicate the situation, it arrives loaded with suspended dust directly from the Sahara.
Thermal climbing. The rise in temperatures will be drastic and rapid and throughout the week, the thermometers will climb until they reach values that will exceed the usual average for this time by more than 4 ºC in areas such as the Pyrenees, the Ebro valley and the central-east of Castilla y León.
The important thing is that, starting on Wednesday, the situation increases in level, since the river depressions will stabilize in the thermal range of 40 to 42 ºC and cities such as Seville, Jaén, Badajoz and Ciudad Real will easily overcome the barrier of 40 ºC in the shade.
The critical It will arrive on Friday, and if the forecasts of the European ECMWF model do not change, the run-up to the weekend will be the most suffocating day. For example, the area around Córdoba could register peaks of up to 44ºC, while areas such as Toledo or Zaragoza will orbit around 42ºC.
On hold. Technically, the AEMET has not yet activated the official heat wave warning for this episode, since very strict criteria of intensity, territorial extension and duration must be met (a minimum of three consecutive days). However, with the model data in hand, everything indicates that we are on the verge of the fourth great wave of this season.
That is why, despite the fact that at the moment only a rise in temperatures has been reported and they have activated different yellow and orange alerts In the national territory, in the next few hours this new heat wave could end up being confirmed. And the most important thing is that temperatures are not the only thing of concern, since there is also the possibility of storms appearing that could be locally intense.
