The beginning of the week will be marked by a "sharp" drop in temperatures due to the emergence of an arctic air mass, which will leave winter and frosty temperatures in much of the country, according to the State Meteorological Agency (Aemet) in a statement. informative note.
For this Monday, daytime temperatures are expected to plummet in much of the interior of the northern half, with this decline being especially pronounced in Aragon, eastern Castilla y León, northern Madrid and Castilla-La Mancha and northwest Catalonia.
In Barcelona, for example, they will not exceed 16 degrees. It will be even colder in Palencia, Oviedo, Santander, Segovia or Soria, where the thermometer will not rise above 14 degrees. Weak frosts will be recorded in mountain areas of the northern peninsula, more intense in the Pyrenees and without ruling out that they will extend to areas of the mountainous environments and northern plateau.
Furthermore, a trough is expected to approach the Mediterranean area with a tendency towards instability in the eastern Peninsula and the Balearic Islands.
According to the agency, cloudy skies are expected in the northeast of the peninsula and in the Balearic archipelago, with rainfall that will extend to the rest of the Levantine area and southeastern third of the peninsula, and may be accompanied by storms, especially during the afternoon. The rains may be locally heavy in eastern Catalonia, where the yellow warning has been activated.
Tuesday will be the "peak day of this episode" with minimum temperatures that are likely to be significantly low for the time of year, Aemet points out in its statement. During this day, the decreases in maximum temperatures would continue and the frosts will extend to large areas of Castilla y León, the north and east of Castilla-La Mancha, the south of Aragon, as well as the Pyrenees, where they may be strong locally.
Starting in the second half of Tuesday, the Atlantic anticyclone is expected to move towards the southwest, so it is likely that the emergence of very cold northern air will cease and therefore this episode will end, with a general rise of temperatures starting Wednesday, the agency concludes.
