This Monday will be a day of transition for the peninsula and the Balearic Islands between anticyclonic weather and a situation of greater instability that will affect the northern half of the peninsula and the archipelago, where cloud cover will increase from northwest to southeast.
According to Aemet, cloudiness will increase from northwest to southeast in the northern half and in the Balearic Islands, with precipitation in the Cantabrian area, upper Ebro, northern Iberian and Pyrenees. Scattered rains are not ruled out in other areas of Galicia, this part of the Central system and the rest of the Iberian system.

According to Aemet's forecast, during the week of November 20 to 26, an Atlantic circulation will enter with colder air, which will leave large amounts of rain in the northern third and the Balearic Islands, although they will be less likely in the Iberian and Central systems and without ruling them out. in areas of both plateaus and in the southeastern mountains. In the mountains they will be in the form of snow.
