The rise in temperatures is not expected until the weekend, so the snow cover and ice will persist for several more days.
On the third morning of the historic cold wave suffered by the center and the northern half of the peninsula, Castilla-La Mancha and Aragón lead the ranking of the coldest night, where the towns of Molina de Aragón (Guadalajara) and Calamocha (Teruel) have recorded the lowest temperature in the network of stations of the State Meteorological Agency (Aemet), with 19.9 and 18 degrees below zero, respectively.Behind them are the Teruel towns of Santa Eulalia del Campo (-17.8 degrees), Bello (-17.3 degrees) and Teruel-capital (-15.4 degrees), where the thermometers give no respite in this episode of extraordinarily low temperatures, which affects almost the entire country, except the Canary Islands.In other points of the peninsular interior, Daroca (Zaragoza), Arganda del Rey (Madrid), Fuente del Sol (Valladolid), Alcázar del Rey (Cuenca) and Aranda de Duero (Burgos) the values have oscillated between 14.9 degrees below zero and 13.7 degrees below zero.In general, these records are slightly less cold than those reached in the early hours of Monday to Tuesday, the coldest of this episode, when night temperatures plummeted to 25 degrees below zero in Bello (Teruel) and Molina de Aragón (Guadalajara) giving rise to values never seen since 1963.This slight rise in nighttime values has also been noted at the Calamocha station (Teruel), which has the official historical record of cold in Spain (on December 17, 1963 it dropped to 30 degrees below zero), in which this morning the thermometers have registered three degrees more than yesterday.The Community of Madrid, one of the most affected by this first cold wave of the year, has thrown in the early hours of this Wednesday a minimum of 6.9 degrees below zero at the Retiro Park station, record less cold than yesterday, when 7.3 degrees below zero were reached, data only comparable to another similar one recorded in 1981.
When does the cold subside?
For this Wednesday, the Aemet foresees that the temperatures will increase in the interior of the peninsula, while the minimum will do so in a “pronounced” way in central and eastern areas, although they will remain abnormally low for the time in Madrid and Castilla-La Mancha.
Specifically, the agency has activated red level warnings in Guadalajara, Teruel and Zaragoza and orange (important risk) in Soria, Albacete, Cuenca, Toledo and Madrid; and yellow warnings (risk) in Cádiz, Córdoba, Granada, Huelva, Seville, Huesca, Cantabria, Ávila, Burgos, León, Palencia, Salamanca, Segovia, Valladolid, Zamora, Ciudad Real, Barcelona, Lleida, Cáceres, Badajoz, Lugo, Ourense, Pontevedra, Murcia, La Rioja and Valencia.
“It is difficult to anticipate the melting of snow, because it depends on the accumulated thickness, the temperatures and the work of the cleaning teams. However, there are models that do allow an approximate estimate of the retreat”, explains Samuel Biener, meteorologist at Metored. “On Wednesday, as soon as the sun rises, temperatures will rise faster than these past days and the melting will be noticeable outside of the mountain systems.”
However, the expert warns: “The snow cover will continue to be extensive at night, although much thinner, in the interior of the Community of Valencia, Catalonia, low-lying areas of Madrid and Castilla y León. In much of Albacete it will be less than 5 centimeters thick”.
After the cold morning of Thursday, explains Biener, “the day will return the decreasing trend to thickness and that same day, late in the afternoon, the accumulated ones seem to be testimonials in the interior of Catalonia, the Ebro valley, almost the entire Community of Madrid and in the southern interior of the province of Valencia”.
On Friday the decline will continue and eventually “on Saturday a large part of the Community of Madrid, interior of the Valencian Community and Catalonia -except for the highest reliefs-, as well as the low areas of Castilla-La Mancha, will be free of snow”.
“On Sunday, it will only remain in ‘usual’ sites of the Iberian System, Central, Cantabrian Mountains, Pyrenees and Sierra Nevada. On Monday, predictably, normality will already be established in almost the entire Peninsula., concludes the meteorologist.
