Christmas Eve and Christmas, dense fogs and mild temperatures of up to 19 degrees

Stable weather and mild temperatures, up to 19 degrees in Levante and Andalusia, will be the protagonists of the Christmas holidays in almost all the country, except in areas of the interior of the peninsula, where the persistent and intense fog banks will leave colder values .

The presence of a "powerful and persistent anticyclone" on the Peninsula is responsible for this atmospheric stability, according to the State Agency of Meteorology (Aemet), which warns of the formation of large and dense banks of mists, more persistent in the depressions of the rivers, especially in the Duero and the Ebro.

The fog is a very common phenomenon of winter, in a situation of high pressures, because the cold air is confined in the valleys and in the lower areas, where there is more humidity and leads to the formation of large banks of fog.

These fogs occur more easily in river valleys for two reasons: on the one hand, the cold air coming from the slopes that close them usually descend to the heavier and is accumulated in them; and on the other hand, there is sufficient humidity, coming from the rivers that cross them, so that the fog forms.

Regarding temperatures, Monday, Christmas Eve, the values, in general, will be higher than usual, except in areas where fog banks persist, on the Cantabrian coast and in the Pyrenees and, by the otherwise, they will rise in the peninsular center and southeast, high Ebro and in the Cantabrian mountain range.

By provincial capitals, Almeria, Barcelona, ​​Cádiz, Gerona, Granada, Córdoba, Huelva, Malaga and Seville will reach very mild highs between 19 and 20 degrees, while in A Coruña, Alicante, Bilbao and Pontevedra the thermometer will remain at 18 degrees.

In cities of the interior such as Madrid and Guadalajara, temperatures will be at 14 and 16 degrees respectively, and, as a curious fact, no provincial capital, except for Palencia, will be below 8 degrees in daytime tomorrow.

At night, the coldest minimum will be recorded in the provinces of Castilla y León and Teruel with temperatures between 0 and 2 degrees positive, while the warmest night will be recorded on the shores of the Mediterranean, where Barcelona and Almeria will stay in 11 degrees Celsius.

For Christmas Day, the situation will not change and it is expected a little cloudy sky or with high clouds and mists and fogs in both plateaus, in the depressions of the peninsular northeast and in points of the Strait, although, in general, they will be less extensive than in past days.

During that day, the maximum will fall in the Cantabrian coast and in much of the peninsular east and will rise in both plateaus and in the depressions of Aragon and Catalonia, except in the fog zones.

In the Canary Islands, the position of the anticyclone will continue causing a southeasterly wind with strong gusts, causing an increase in temperatures and the formation of hail, although on the 25th an Atlantic front could affect the westernmost islands, with the possibility of some rains on the island of La Palma.

As of Thursday 27, it is likely that an Atlantic front affects Galicia and then the rest of the peninsular north end with rain.

In the rest of the Peninsula and the Balearic Islands the stable atmosphere will continue to predominate, with fogs in interior areas and temperatures with a downward trend; in the Canary Islands it is most likely that the trade winds prevail with a stable atmosphere.

During the last weekend of the year, and even with much uncertainty, the weather will remain stable in much of the country, although some scenarios mark the "possibility of weak precipitation" in points of the eastern Cantabrian coast of the southeast peninsula, Andalusia, Ceuta , Melilla and the Balearic Islands and with values ​​that will begin to descend.
