The weather improves this Wednesday in much of the country, after the DANA Alice will leave intense rains mainly in areas of the Mediterranean. However, some instability will still persist in parts of the eastern peninsula and the Balearic Islands, due to a mass of cold air at altitude that will gradually weaken. Besides, weather models already anticipate an important change: The polar jet will be activated in the coming days and will make way for a succession of Atlantic storms that will affect a good part of the country.
Weather warnings for today
According to the prediction of the State Meteorological Agency (AEMET), There is a yellow warning for heavy rain and storms until 11:00 a.m. in Menorca and the north and northeast of Mallorca.. In the afternoon, Starting at 4:00 p.m., the warning is activated in the pre-Pyrenees of Barcelona and in the Girona Pyrenees.. Also in Galicia we will have to be careful. In Lugo, both in the center and in A Mariña, there is a yellow warning due to dense fog that could prevent visibility beyond 200 meters.
During the day, evolution clouds will form in scattered areas of the interior of the peninsula. Locally strong showers accompanied by isolated storms are expected in the east of the eastern Pyrenees and less intense rains in the eastern interior of the peninsula, especially in mountain areas. In the rest of the country, more stable weather will prevail, with sunny skies and some low clouds in the north of Galicia and the Cantabrian coast. In the southwest, medium and high cloudiness will increase throughout the day.
In the Canary Islands, abundant cloudiness is expected, especially of medium and high type, with a low probability of rain on the islands with greater relief. Temperatures will hardly change. The highest maximums will be recorded in Badajoz and Seville (32 ºC), and Córdoba (31 ºC), while they will be milder in cities such as Huesca (21 ºC) and Albacete (22 ºC).
Stable weather until Sunday
The weather will remain stable on Thursday and will continue on Friday, although showers are not ruled out in some provinces in the Mediterranean area and in mountainous areas of the interior of the peninsula. These precipitations could be locally strong, especially at high points in the center, east and south.
Temperatures will drop slightly, although it will still be hot for this time in the west of the peninsula. In cities like Badajoz, Córdoba or Seville it will exceed 30 degrees, while in the south of Galicia it will reach close values. In the center of the peninsula, Madrid will reach 25ºC and in Salamanca or Zamora it will reach 27ºC.
On Saturday stable weather will predominate, although A front that will approach from the northwest could leave weak rains in parts of Galicia, without ruling out some rainfall in Asturias, the Cantabrian Mountains and the Catalan coast.. Fog banks will also form in the interior, mainly in the northern and eastern thirds. Temperatures will rise noticeably this Saturday in the Cantabrian Sea due to the arrival there of southerly winds. In Bilbao it will be around 30 degrees, just like in Badajoz, Ourense or Seville.
Looking ahead to Sunday, the front that entered the northwest of the peninsula on Saturday will advance towards the east, leaving rain in Galicia and the Cantabrian communities, without ruling out that this rainfall will spread to other areas. The sky will remain cloudy in the north of the Mediterranean area, with some rain again in coastal areas of Catalonia.
The polar jet will take off
For his part, meteorologist Samuel Biener (Meteored) advances that The European model predicts that the polar jet will pick up steam in the coming days, which will mark a radical change in the meteorological situation in Spain. This strengthening will bring with it the arrival of storms and Atlantic fronts that will affect a good part of the country.
Galicia will be, once again, the community most affected by the rains starting on Sunday. The succession of several fronts over the next week could leave accumulated more than 100 liters per square meter in western areas. Furthermore, if the current scenario continues, it is not ruled out that rainfall will be locally intense and even accompanied by storms.
The rains will also extend, although with less intensity, to other regions of the northern peninsula such as Castilla y León, Asturias, Cantabria, Basque Country, Navarra and La Rioja. In these territories, occasionally intense showers could be recorded, but with less significant accumulations than in Galicia.
However, Bieneer indicates that uncertainty remains high regarding the impact of this new Atlantic circulation in the center and south of the country. Some models suggest that the fronts will be able to maintain their activity upon reaching these areas, while others suggest that an anticyclonic ridge could slow their advance.
