This weekend, there will be a significant change in the weather in the Iberian Peninsula due to the approach of a dana, an air mass pocket in the upper layers of the atmosphere. This dana will bring widespread showers that could be strong or even very strong, accompanied by a remarkable drop in temperatures. The dana will enter through the Gulf of Cadiz, affecting the southwest region first and then extending to most of the Peninsula, except for the Ebro Valley and the Mediterranean area. The cool weather will persist throughout the following week, with temperatures going from very high to cool for June.
The abrupt change in weather will cause a sharp drop in temperatures after a period of intense heat across the country. The warm nights, with temperatures not dropping below 25°C in some areas, will be replaced by cooler conditions. Showers with thunderstorms, potentially heavy and accompanied by hail, are expected in regions like Galicia, Asturias, and Castilla y León. There are alerts for rain and storms in several regions, including Asturias, Castilla y León, Aragón, and Galicia.
On Saturday, the unstable weather will persist, with showers likely to fall almost anywhere in the Peninsula except for Catalonia, the Mediterranean coast, and the Balearic Islands. Rain will be intense in northern regions in the morning and will spread throughout the north and east in the afternoon. While some areas will continue to experience heat, notably in the northeast and the Mediterranean regions, temperatures will drop significantly in the central part of the Peninsula. A decrease of over 10°C in temperatures is expected in some areas.
Sunday will see continued instability, with showers forecasted for the northern and central regions of the Peninsula. The heaviest rain is expected in the northeast, with significant accumulations in regions like the Basque Country and Navarre. Showers may also be intense in Aragón and Catalonia. Cooler temperatures will extend to the northeast, with a significant drop in places like Pamplona and Zaragoza. The Levant region, however, may experience warmer temperatures.
The weather will remain unsettled on Monday, although the cause will shift from the dana to a cold air trough in the upper troposphere. Showers are expected in central regions of the Peninsula, from southern Castilla y León to northern Extremadura, passing through Madrid and parts of Castilla-La Mancha. Temperatures will be cooler in the Mediterranean region and Extremadura, with overall cooler conditions for the season. Showers may continue in the following days, especially in the north and central regions, but a more stable weather pattern is expected later in the week. Canarias will remain unaffected by the dana, with scattered showers and mild temperatures.
