BarcelonaThe heat and stuffiness have once again been very intense for the umpteenth consecutive day and, in fact, have intensified, with maximums that have once again stood today between 36 and 40 ºC in the interior. Around 40 ºC were reached, especially in Ponent and the southern interior, but also in some parts of the Central Catalonia or the northeastern interior, with unbridled heat. The 40.6 ºC reached in Cardona, in Bages, stand out.

This Wednesday the thermometers will recede, although with values that will continue clearly above average. But pay attention, because on Thursday there will be another peak of extreme heat in the interior of the country. Meteocat has activated alerts for intense heat in many regions for Thursday.

However, on Friday the mercury will start to drop, and this thermal descent will be accentuated between the weekend and the beginning of next week. Therefore, we are on the verge of some days with more normalized temperatures, more bearable heat, and more pleasant nights overall. Before, however, we will have to pay the torrid toll of Thursday.

Wednesday: temperatures drop

Tonight will again be warm and restless in several regions, especially along the coast, pre-coast, south, and west. The mercury may drop slightly, but tropical lows will repeat and be quite widespread, while there will again be torrid lows in coastal areas and in the south of the country. Meteocat maintains the alert for nocturnal heat in several regions.

The highs will decrease generally, with many values from 32 to 37 ºC and marked stuffiness on the coast. 40 ºC will not be reached in Ponent and the Ebro valley. All this with a Sun that will once again combine at times with some bands of high and medium clouds and dust in suspension. Afternoon cloudbursts will grow in the Pyrenees that will hardly leave rain, while in the afternoon new showers are not ruled out in the Terres de l’Ebre.

Scorching picture before the 'refreshment'

Thursday will see a surge in intense heat as we continue under the effects of the North African warm bubble. This rise will be pronounced inland, especially in Ponent and the Ebro valley, where maximum temperatures will be recorded between 41 and 44 ºC, with a torrid and suffocating atmosphere. On the coast, there will be few changes, with marked mugginess.

All of this will be the grand finale before the expected drop in thermometers. This descent will begin on Friday, but we will not notice it more generally until the weekend and the beginning of next week. A big cool-down is not coming, but the heat will be much more bearable, and we will also sleep better at night. Apart from some showers, no significant rain situation is in sight.
