Low temperatures and fog will have a yellow warning for Aragon, Castilla y León, Castilla-La Mancha, Catalonia, Galicia, Madrid, Navarra, the Basque Country and La Rioja on the morning of the last Sunday of the year.
According to the forecasts of the State Meteorological Agency (Aemet), in some cases the warnings will be given due to both minimum temperatures and fog, specifically in Aragón, Castilla y León, Castilla-La Mancha and Catalunya. For their part, Galicia, Navarra, the Basque Country and La Rioja will only be warned due to fog, while Madrid will be warned due to low temperatures.
The agency explains that this low morning cloudiness will leave mists and fogs in large areas that will generally tend to lift but which are expected to be denser and more persistent on the Northern plateau, Ebre valley, depressions in the northeast, interior of Galicia and points in the Southern plateau. They could be locally frigid.
The minimums in León and Palencia
Beyond the morning with clouds, the Aemet indicates that on Sunday there will be an anticyclonic situation with a predominance of slightly cloudy or clear skies and an absence of precipitation.
Regarding temperatures, the provinces with the lowest minimums will be León and Palencia, both with minus three degrees. These are followed, with minimums of minus two degrees, by Ávila, Burgos, Salamanca, Segovia, Toledo and Zamora. With this panorama, frosts will continue to affect large areas of the interior of the northern half of the peninsula, the southern plateau and the southeastern mountains, without ruling out locally in Mallorca, moderate in large areas of the interior, and could reach severe temperatures in areas of the Iberian Peninsula and the Pyrenees. .
León, one of the provinces with the coldest temperatures.
In the Canary Islands there will be stable weather, with a predominance of slightly cloudy skies and the possibility of some weak and scattered precipitation in the north of the islands with greater relief. Light haze is expected, with higher concentrations in the eastern islands. For its part, maximum temperatures will not experience major changes in general, with decreases in the Cantabrian Sea, the eastern Canary Islands and areas of the Northern plateau.
Light winds from the west will predominate in the northern half of the Mediterranean area, and from the east or calm winds in the rest. Moderates are expected in the Canary Islands and coastlines of the extreme northwest and south of the peninsula, with possible intervals of strong easterly weather in the Strait and Alborán.
Fog on New Year’s Eve
Between Tuesday, December 31 (New Year’s Eve) and Thursday, January 2, instability is expected to increase in the southeast of the peninsula and the Balearic Islands, where showers could occur that could occasionally be accompanied by storms and be locally strong on the coasts. from the southeast. In the rest of the peninsula, during New Year’s Eve the fog will continue persistently in the areas of previous days, although it will decrease in extent and persistence. Temperatures will barely change and frost will become widespread in the northern half. In the Canary Islands, stability will continue with the haze in remission.
The uncertainty in the forecast increases from Friday, January 3, until Sunday, the 5th. However, it is most likely that the anticyclone will move towards eastern Europe, which would allow the arrival of frontal systems from the Atlantic.
These Atlantic fronts would leave widespread rains in Galicia and the Cantabrian Sea, without ruling out their advance towards the rest of the peninsula and the Balearic Islands. And it could snow in mountainous areas of the northern half.
Minimum temperatures will tend to rise, so the frosts will be less intense and extensive. The Canary Islands could continue with dry weather and temperatures with few changes, although an increase in instability is not ruled out on the first weekend of January 2025.
