Will the “snowdrops” continue for the December bridge? This is expected
In the last hours the snowfalls are being very significant in the eastern sector of the Cantabrian Mountains, the Basque Mountains and in the Pyrenees, where the north flow associated with a maritime arctic air mass favors the retention of rainfall in these sectors, as we anticipated in Meteored. In those sectors that are better exposed to the nortadas, the depths of snow already exceed one meter. Without a doubt, great news for ski resorts.
In the coming days we will have to be very aware of the risk of avalanches and the flooding of the rivers due to the thaw. This year winter has come early, with a succession of polar or arctic air outbreaks in the final stretch of November. Will this situation continue in the beginning of December? There is very little left for the Immaculate Bridge, and many people are watching the evolution of the meteorological situation.
Just before, thermal ups and downs and the passing of fronts
According to the forecasts of our confidence model, the HRES-IFS of the ECMWF, everything indicates that The anticyclone of the Azores will largely determine the time we will have in the medium and long term in Spain, taking charge of “directing” air masses of different nature, depending on their position.
Ski season: December bridge with open seasons?
For now, It seems that in the next few days the zonal circulation will return in high latitudes, with some small ripples which can be translated into a drop-off in the surroundings of the Iberian Peninsula between Tuesday and Wednesday. The temperatures will go up, but they will collapse again between Wednesday and Friday, with the arrival of a new outbreak of polar air, with rains and snowfalls that will again be important in the northern half.
The bridge will start with an anticyclone and could end with instability
As of Friday, the anticyclone of the Azores will gradually approachAlthough between Saturday and Sunday a fairly active frontal system will probably leave rainfall in the northern half and in quite a few areas of the center, while it will reach the Mediterranean very weakened.
For the day of the Constitution and Monday 7, the anticyclone will get closer to the Peninsula, and with this the rainfall would tend to retreat in the northern half and in the Balearic Islands. However, on the day of the Immaculate Conception, another front could arrive and a new thermal decline. Everything indicates that it will be a real headache to pack for the bridge, since a little of everything is expected, especially in the center, the Balearic Islands and in the northern half.
All in all, it looks cold and very humid in the north
According to the ECMWF, for the days of the bridge, rainfall is expected much higher than usual for the dates on the Cantabrian slope, especially in the eastern sector. It raises a similar scenery in the Pyrenees, especially on the north face, while in the north half and in the Iberian System the normal climatological values will be around. In the rest of the Peninsula and in both archipelagos, less precipitation is expected compared to the average, although in the Balearic Islands the uncertainty is greater. A lot of wind is also expected on the Cantabrian coast, mountain areas in the north, northeast of Catalonia and in the Balearic archipelago.
When it comes to temperatures, values of 1 to 3 ºC lower than normal on the Galician coastline could be registered for the bridge, while in the Balearic Islands, the Canary Islands, the Cantabrian coast, the Strait and the Gulf of Cádiz, they could be up to 1 ° C below normal. In the rest, no significant anomalies are observed.
Tendency towards stability in the Canary Islands
In the Canary Islands the situation will gradually tend to stabilize, after a few last days in which the storms and snowfalls on Mount Teide are being the protagonists of the meteorological situation. For the holidays they will probably have a more stable environment, with trade winds and somewhat higher temperatures. There could be some rains on the islands of greater relief.
