Molina de Aragón (Guadalajara) exceeds -25ºC at dawn, and 10ºC reaches some districts of Madrid.
The center of the Iberian Peninsula has experienced its coldest morning in the last 20 years, with Molina de Aragón (Guadalajara) reaching -25.2ºC at 8:30 a.m., and Teruel and Calamocha reaching -21ºC at the same time. Daroca and Alhama de Aragón (Zaragoza) have reached -18.5ºC and -17.8ºC, respectively, and points in Ávila, Cuenca and Segovia have exceeded -16ºC. At the La Vasequilla station (Checa, Guadalajara), located in a valley and which usually marks the minimum in the center of the peninsula, temperatures reached -33.6ºC first thing in the morning. In Madrid, Ciudad Universitaria has exceeded -10ºC while Alto de los Leones was at -7.4ºC.
The copious rainfall that has accompanied the Filomena storm and that has caused a historic snowfall in Madrid, of more than 30 hours and with an accumulation of 50 centimeters of snow in some neighbourhoods, has given way to a winter anticyclone. The skies will remain clear and windless throughout the week, except for points in the Bay of Biscay and the Pyrenees. A situation that, although it has helped to reduce the accumulated volume, combines the factors that will cause a cold wave destined to go down in history.
Rubén del Campo, spokesman for the State Meteorological Agency (Aemet), thus explains the mechanisms behind the phenomenon: the cooling of the ground is “accurate” in winter due to the scarcity of hours of sunshine, especially when there is no precipitation. If it is also covered with an abundant snow cover, “barely absorbs the sun’s heat, but reflects it by night cooling”. It is then that we can expect “extremely low” minimum temperatures in areas of valleys or valleys of the land.
Thus, the first blow of the cold wave has occurred in the central area of the Peninsula where there is snow on the ground, with temperatures that have reached -18ºC in Morón de Almazán or Burgo de Osma, both in Soria. -17ºC were also reached in Molina de Aragón while in provincial capitals, in Toledo and Soria the minimum dropped to -8ºC. The ice has appeared in Cuenca and Guadalajara, with a minimum of -7ºC. The center of Madrid, in the Parque del Retiro, reached -3ºC, but the Barajas airport dropped to -8ºC.
The thermal ascent will begin on Wednesday, progressively recovering the maximum conventional values, although the minimum will remain very low until Friday. Frosts and minimum temperatures below normal will continue in large areas of the interior, especially in the two plateaus and the moors of the central zone, since -5ºC is still expected. The highest daytime temperatures will be found in the Mediterranean coast, where they can be around 15ºC.
“The temperatures of these days could break the minimum records. The temperatures are well below normal at this time of year and yes, we know that January is a cold month, the coldest of the year in our country, but this situation is unusual“, points out Mar Gómez, Ph.D. in Physics and head of the meteorology area of eltiempo.es. Albacete, Cuenca, Toledo, Teruel, Ávila, Guadalajara, Madrid, Soria and Segovia would form the ‘top 10’ of the coldest, with Palencia and Valladolid tied for tenth place.
Madrid, colder than the Sierra
The Community of Madrid maintains the orange alert for minimum temperatures of -12ºC in the Sierra of Madrid, but also in the metropolitan area, which can reach -10ºC, although the sensation of cold in the streets of the capital will not be so much. However, it is the west, the south and Las Vegas where the bloodiest will intensify. In the area of the Tagus plain, temperatures below -12 degrees can be reached.
On Wednesday, however, the Sierra is free of cold alerts: the temperatures will be lower in the metropolitan area itself and the Henares corridor, -7 degrees or yellow warning; and even more so in the west, south and vegas, with -8ºC and an orange alert.
La Mancha: attention to the south and east
Castilla-La Mancha continues with an orange and yellow level in all its provinces due to very low values, which in points of Parameras de Molina (Guadalajara) will drop up to 16 degrees below zero. The main notices in red and withup to -14ºC, they are concentrated in La Mancha in Albacete and Cuenca, and the Sierra de Guadalajara. For Wednesday, these areas would go to the yellow level with minimums not exceeding -9ºC.
Lion: freezing fog
The east of Castilla y León and mountain areas will suffer the worst part, to which is added a fog alert that can favor the formation of ice sheets. The Soria plateau is in red warning for -16ºC, and in orange for -10ºC the plateaus and systems of Burgos, Ávila and Segovia. All the rest of the Community is on yellow notice due to thermometers that can mark up to 6 and even 8 degrees below zero.
Aragon: collapse in Teruel
Red level warnings remain active for minimum temperatures that can reach -15 degrees Celsius in the Sierra Ibérica of Zaragoza and in the areas of Albarracín and Jiloca, in the province of Teruel. They also consist of a orange warning for up to -13 degrees below zero in Gúdar and Maestrazgo, and another yellow for l-4ºC in the province of Huesca, Cinco Villas and Bajo Aragón.
The rest, from orange to yellow
Catalonia continues with an orange notice in multiple points of the Pyrenees by minimum values that will drop to 10 degrees below zero. In the provinces of Almería, Granada and Jaén (Andalusia), Cáceres (Extremadura), Lugo and Ourense (Galicia), Castellón and Valencia (Valencian Community), the Region of Murcia, the Foral Community of Navarra and La Rioja there is a yellow alert (risk). for minimum between 4 and 6 degrees below zero.
