The march of the storm Filomena, which has left unprecedented snowfall in the center of the peninsula in the last hours, does not mean that the situation will calm down. In the next few hours it is expected that the storm will move towards the Mediterranean and will be noticed until noon on Sunday in Aragon – where the red alert remains active for heavy snowfalls -, the interior of Castellón and the coastline that runs from Girona to the north of Alicante, where strong winds are expected.

However, Filomena is going to be replaced by a cold wave that will lead to a “sharp drop” in temperatures starting Monday, with lows below 10 degrees below zero in mountain areas and flat areas that have suffered snowfall in recent hours , affecting points where this circumstance is very rare. The communities where this cold wave will be most noticeable will again be Madrid, Castilla y León and Castilla-La Mancha, although the south of Ourense or areas of Aragon will also be affected.
In some areas “the maximums will also remain very short”, with difficulty exceeding zero degrees and even falling below that record, according to the latest data provided by the State Meteorological Agency, Aemet, which indicates that the intense cold will spread at least until Thursday.
Aemet explains that from the early hours of Sunday to Monday, “a marked decrease in night temperatures” will begin, which will continue the following night, with strong frosts in large areas of the interior and minimum temperatures, which will be less than 10 degrees negative in mountain areas and flat areas with snowy surfaces, “affecting points where this circumstance is very rare.”
The phenomenon is explained because the march of the storm Filomena will favor the entry through the west of the country of an Atlantic anticyclone that will stabilize the situation, in addition to promoting a marked decrease in night temperatures, with widespread frosts in the central zone and inland areas of the eastern half, which is where the most important snowfalls are being recorded.
As of Wednesday, a notable rise in temperatures will begin, especially at night, especially in mountain areas, although the frosts will still be very important in flat areas of the center, both early Wednesday and Thursday.
The Aemet indicates that, although between the early hours of Thursday to next Friday, it is probable that the frosts will continue in the interior of the peninsula, these will be “less severe”, ending the episode of the cold wave.
