The coolest and rainy time of the usual that has reigned throughout May is over. During the, with progressively higher temperatures in the Peninsula and Balearic Islands, which will lead to the first warm episode of the year, with temperatures above normal for this time of the year. The cause of this change of time, in which it warns of the situation, is “in the presence of a powerful anticyclone centered on azores and extends to the entire peninsula and the Balearic Islands, giving rise to great stability, virtually clear skies and a high insolation.”
The next few days the increase in temperatures “will be quite widespread and progressive”, so that the 36 ° -38 ° in the Guadalquivir Valley and the 35 ° in the Guadiana will be reached during this Monday and Tuesday.
But the worst will come from Wednesday, when a mass of warm and dry air will join this native heat. Thus, that is likely that the presence of an isolated depression in high levels of the atmosphere (Dana) between the Canary Islands and the Gulf of Cádiz “Induces a wind of southern component that drags a mass of warm, dry and with suspension dust”, of African origin. This mass will first reach Andalusia and Mar de Alborán and then to the peninsular center.
As a consequence, there will be “an additional increase in temperatures, with values of summer and, therefore, clearly higher than usual at this time.” The most affected areas, according to the AEMET note, will be the southwest peninsular quadrant, the Central and the Ebro Valley. The attempts will probably be on Thursday and Friday, with maximum temperatures around 35 ° on the North Plateau, 37 ° in the valleys of the Ebro and the Tagus, 39 ° in the Low Guadiana and 40 ° -42 ° in the Guadalquivir.
And it will heat the day, but also at night. The minimums will also rise, but more slowly and less intense. On Thursday and Friday there will be tropical nights, that is, above 20 °, only in areas of the southwest quadrant; And on Saturday, it will occur in large areas of the southern half, the peninsular and Ebro center.
The north of Galicia and Cantabrian area will be outside this episode due to the fresh flow of the north. The Canary Islands will not be affected due to the persistence of the Alisios. Inside Mallorca, the 30th will be exceeded from Friday.
“The uncertainty of the situation increases facing the weekend, so it is difficult to specify the end of this episode,” confesses the aemet. It is likely that from Saturday, instability will increase, which could lead to an increase in cloudiness and some storm, which, together with the possible calima, would cause the beginning of a decrease in temperatures.
