In many regions of Spain, the last week of the year will bring a big time change important. The stable anticyclonic climate that has graced us during the Christmas holidays will give way to a period of instability as new Atlantic fronts, nourished by a river of subtropical atmosphere, make their presence known.
In this article we are going to tell you how the great change in weather that is coming to us at the end of the year will affect Spain.
big time change
Initial rainfall will appear on Wednesday in Galicia and will intensify as more active fronts enter the scene. As we approach the New Year's Eve weekend, Uncertainty is growing, but it looks like we will also experience a surge of frozen polar air. Despite the presence of morning and afternoon fog, the sky will remain partly cloudy or clear throughout the day on December 26.
According to the State Meteorological Agency (Aemet), the forecast for the coming days indicates that fog and frost will be predominant in the northern Plateau and interior regions of the Peninsula. This will especially affect Aragon, Castilla y León, Castilla-La Mancha, Catalonia and Extremadura, where there is a yellow warning for minimum temperatures of up to -6º. In addition, Galicia will experience intervals of strong winds on its coasts.
Fog will persist locally in areas such as Ávila, Burgos, León, Palencia, Salamanca, Segovia, Soria, Valladolid, Zamora, Huesca, Badajoz, Cáceres, Madrid and Lleida. Limited visibility of only 200 meters can be expected in the western part of the southern plateau and areas of the Ebro basin, including Badajoz and Cáceres. In addition, the provinces of Teruel, Zaragoza, Cantabria, Orense, Segovia, Soria, Palencia, León, Burgos, Valencia and Zamora will be at risk due to minimum temperatures that will reach -6º.
Frosts for the end of the year
These extremely low temperatures will cause frost in much of the interior of the peninsula. Cloud cover is expected to increase in Galicia as an Atlantic front approaches, making precipitation possible in the western part of the region towards the end of the day. There is also a chance of some rainfall in the eastern part, although this cannot be completely ruled out. The Canary Islands may experience intervals of cloudiness, especially on the islands with greater relief, There is a possibility of slight haze affecting the entire archipelago.
Maximum temperatures will decrease in the northern quadrant of the peninsula and southwest, while the rest of the areas will see few changes. Minimum temperatures, on the contrary, will rise in the northwest of Galicia. Wednesday will start with fog and frost in the interior. As the front associated with the Atlantic storm advances, the rains will reach the northwest of the peninsula, with persistent rainfall in the west and weaker rainfall in Asturias and Castilla y León towards the end of the day.
The presence of a subtropical atmospheric river originating in the Atlantic will enhance these precipitation events, similar to the phenomena observed in situations of air massesThe rest of the country will experience stable weather conditions with predominantly high cloud cover.
On Tuesday, the cities of Zamora and Valladolid could experience highs of between 2 and 3°C. However, on Wednesday, these temperatures could soar to ten degrees. Furthermore, persistent fog could dissipate, allowing for higher highs in certain areas of the Ebro Basin, especially around Lleida. Along the Mediterranean coast, Temperatures will be around 18 and 20º during midday.
As we approach Thursday, the front will lose strength as it moves inland, causing precipitation in Galicia, Asturias and Castilla y León. A slight increase in temperatures is expected, which will cause localized and less intense frosts compared to previous days.
The upward trend in temperatures will continue on Friday, especially at night. Light frosts may occur in certain areas of the northern plateau and central region. Throughout the Mediterranean, daytime temperatures will decrease. Precipitation is expected in Galicia, Asturias and Castilla y León, with the possibility of precipitation in the extreme north. Snowfall is expected in the Pyrenees and the Cantabrian Mountains at altitudes above 2.600 meters.
Great change in weather due to an outbreak of polar air
Looking ahead to next weekend, the forecast suggests the arrival of an outbreak of polar air that will bring colder temperatures and snow. On Saturday a new front will cause rain and snow in the Cantabrian Communities, the Alto Ebro and the Pyrenees. Temperatures will drop in most areas, except in the east of the peninsula, the Balearic Islands and the Canary Islands. For New Year's Eve, rain is expected in the Eastern Cantabrian Sea and snowfall in the Pyrenees, which will gradually decrease in the morning. The atmosphere will be even colder than Saturday, causing a general drop in temperatures.
According to the AEMET, uncertainty will increase significantly on New Year's Day, Monday, January 1. Two different scenarios are foreseen. The first scenario implies a predominantly stable anticyclonic climate with minimal rainfall. The second scenario assumes the potential arrival of a new frontal system to the northwest of the peninsula, which could advance inland throughout the day bringing rain, especially to the western regions and Cantabrian communities. Additionally, temperatures are expected to increase significantly due to light winds blowing from the west and southwest.
Although it may not seem like good news regarding the good weather, it is necessary for Spain to receive water in order to sustain the drought we are experiencing. Above all, The part of Andalusia is in a more serious drought situation. These precipitations and low temperatures are necessary to alleviate the effects of global warming on a more local scale.
