New Year’s Eve with even warmer afternoons but slightly colder nights

The thermometer continues to set very high values ​​for the time. Today the average of the lows has continued to rise compared to the last days and has already been 6.4 degrees above the reference value of the last twelve years. Despite this, the day has started with a couple of degrees less than yesterday in some capitals of the Pyrenees and Central Catalonia such as Vic, Solsona or Tremp. Among the highest minimums today are the 16 degrees of the Ebro Observatory, Vinyols i els Arcs and Vendrell. Minimum temperatures above 15 degrees are rare in December.

Daily minimum temperature anomaly in Catalonia.

At noon today, it will once again exceed 20 degrees in different parts of the coast and pre-coast. Today’s highs will be similar to yesterday’s, but we should expect a significant rise in the thermometer in the Pyrenees and in some parts of the Empordà. The wind will decrease as the hours go by, after tonight it has still blown with gusts of 78 km / h in Font-rubí, 75 in Pontons and 65 in Tibidabo. Today there will still be a lot of clouds on the northern slope of the Pyrenees, but in general only a few bands of thin clouds will circulate.

Warmer air will continue to come in the next few days and the anticyclone will arrive. This sum of factors will cause the temperature to drop in medium and high altitudes in the Pyrenees, and in general in high points, but, on the other hand, the nights will tend to be a little colder overall, and especially in inland valleys. It will increase the difference between the morning temperature and the noon temperature. Highs will continue to exceed 20 degrees in some places. Tomorrow the temperature will skyrocket, especially in the counties of Girona, where some thermometers will drop to 25 degrees.

Expected difference between today's maximum temperature and Friday's.

The sun will clearly predominate during the second part of the week, but it must be borne in mind that the fog will become more and more prominent in the West and in other inland depths. Looking ahead to the weekend, it could start to be quite persistent, and this will certainly cause the atmosphere to cool down in the West and on the central plateau, despite the strong influx of warm air at altitude. The wind will disappear, also from the counties where it is usually more common.

In the long run today the chances of some rain have increased around the night from Tuesday to next Wednesday. It’s not a clear situation yet, but it will have to be followed. The temperature will tend to drop slowly during the first days of the year. We are likely to arrive in Reis with a more normal feeling for the time, but there are no clear indications that the cold could be intense until at least January 10th.

Chance as a percentage that on Wednesday it will rain at some point in the day.

The driest year in almost 200 years in Barcelona

This 2021 has been so dry in Barcelona that to find a year in which rainfall has been scarcer it is necessary to go beyond the data of the historic Fabra Observatory. Interestingly, the driest year in the centennial history of this observatory is recent. Until now, the record was set in 2015, when only 346 l / m² fell, but in 2021 the rainfall in Barcelona has remained at only 328 l / m².

The work of recovering Meteocat archives means that data on the city’s temperature and precipitation have been available since the end of the 18th century, which shows that in 1835 294 l / m² fell in Barcelona. . This is the last precedent of a drier year than in 2021. It has not rained so little in Barcelona in 186 years. The situation of extreme drought of the last twelve months not only affects the central coast, but also points of the Vallès and to a lesser extent the Alt Empordà. In Badalona this year only 314 l / m² have fallen, in Parets del Vallès 274, in Castelló d’Empúries 312 and in Viladrau 499.
