The The weather will continue to be rainy and windy this Thursday and Friday, because of the remains of the Denise storm that affect Spain. The weekend would bring a anticyclonic environment with great thermal amplitude, according to the State Meteorological Agency (AEMET), and mild days with cold nights typical of the arrival of meteorological winter. The radical change, however, could come soon after with a change of regime and the cold air intake from the north.
The fronts associated with the carousel of Atlantic storms will continue their transit from west to east, explains Rubén del Campo, AEMET spokesman. It will rain throughout the Peninsula except in the south of the Mediterranean area and the Balearic Islands. Rainfall will be abundant in Galicia, western Castilla y León and a good part of Extremadura, with strong winds, and will be in the form of snow in the Pyrenees from 1,800 meters. Temperatures drop in the north.
The fronts will recede across the Mediterranean on Friday, explains Del Campo, and will leave stormy showers in their wake in the Balearic Islands and the eastern half of the Peninsula. Galicia, Cantabria and the Pyrenees will have strong northwesterly winds and more cloudy and rainy skies. However, the instability will clear up as the day progresses.
Two troughs are sighted 〰️
☝️ The first one is already entering escorted by a front that leaves rainfall in the northwest of the peninsula.
✌️ And there will be a second one on Monday, which will bring another batch of ☔

Saturday and Sunday are expected little cloudy skies though although the Sunday a new front will arrive that will leave rain. There will be fog in the interior, especially in the northern plateau, where the atmosphere will be cold throughout the day. night temperatures they will go down “clearly” on Saturday and there will be frosts in mountain areas. It will also freeze in plateau areas and in the moors in the center of the northern half, while the daytime temperatures will generally rise less in the Mediterranean.
Del Campo anticipates that the minimum will be around zero degrees Celsius in Soria and the maximum 15 (ºC), while in the Mediterranean, the Bay of Biscay and the Guadalquivir valley a “mild” environment is expected for the season that will not exceed 20ºC. On Sunday the maximum and minimum temperatures will rise and frost will reduce its extent. Once again, temperatures will exceed 20ºC in the same areas as the day before. In much of the interior of the northern half, the maximum will be around 10 or 15ºC and in the interior of the southern half they will be higher, between 15 and 20ºC.
In the Canary Islands, Del Campo warns of compact clouds and light rain in the north of the most mountainous islands this Thursday. As of Friday the skies will be clear except for some cloudy intervals in the north of the archipelago. The temperatures will rise gradually and from Tuesday or Wednesday the trade winds will intensify.
The anticyclone will be upon us this weekend. With clearer skies and less wind, the rains will be scarce and there will be frosts in inland areas, which in the middle of next week (with still uncertainty) could spread due to the arrival of colder air. pic.twitter.com/2cDQa56Ps5

Possible winter radical change
Regarding next week, the spokesman acknowledges that there are “quite diverse” scenarios. The most probable suggests that the rains will be restricted to the northern third of the peninsula and the Balearic Islands. The temperatures will drop on Monday and Tuesday, and could continue to drop slightly. There will be night frosts in the mountain areas, on the plateau and in the páramos of the center and the northern half.
“The atmospheric pattern that we have had these days of flow from the west, with passage of storms and Atlantic fronts passing into the Mediterranean, could change, at the end of November and beginning of December, and give way to a completely different one with northwesterly and northerly wind inputs due to an Atlantic blockade pattern to the west of the Peninsula”, explains the meteorologist Francisco Martín León of Meteored and the RAM.
“The corridor of squalls across the Peninsula from west to east (with humid and soft air) could give rise to the reorientation of said corridor in the meridional flow from north to south (cold) towards the Iberian peninsula. In this way, there could be a drop in temperatures with snow in northern areas, if the flow has a maritime route, “explains Martín. “There are certain probabilities that a north entrance is brewing with the change of the month and the entrance of the meteorological winter”.
