The arrival of a new front will mark the weather this Friday in much of the country, with overcast skies, widespread rain and intense wind in the north of the peninsula. Galicia will be the most affected community, where showers accompanied by storms and possible hail are expected, locally strong in the west and with significant accumulations.
“We have a weekend ahead of us that will show us the two faces of autumn,” says Rubén del Campo, Aemet spokesperson. The front will move eastward throughout Saturday, leaving rainfall in large areas of the country before giving way to a more stable Sunday, with cold dawns, frost in the northern interior and extensive fog banks.
Rainfall will spread across much of the Peninsula, although it will be less frequent and weaker in the extreme southeast. Significant accumulations could also be recorded in the eastern Cantabrian Sea and in northern mountain areas, where rain could be persistent. Throughout the day, isolated storms could form in the interior and some instability could remain in the northeast of Catalonia. In the Canary Islands, there will be cloudy intervals with the possibility of rain in the north of the islands.
During the day, fog banks and mists will form in mountain areas in the northern half, especially at dawn and at the end of the day.
Temperatures will decrease in the north of the Southern plateau and the northeast of the peninsula, while they will remain without major changes in the north of Castilla y León and the Balearic Islands. In the rest of the country, slight increases are expected, most notable in mountain areas of the northwest and interior southeast. The minimum temperatures will decrease in general, especially in the eastern third and in the Balearic Islands. Light frosts could occur in the Pyrenees.
The wind will blow from the southwest and west in the Peninsula and the Balearic Islands, with moderate intervals and strong gusts in Galicia and the Cantabrian Sea. Very strong gusts are expected on the Galician coasts during the early morning, and also at night in sections of the Cantabrian coast. In the Gulf of Cádiz, the wind will be light from the north, turning west and increasing to moderate; In the Mediterranean area, it will blow from the west with moderate intensity. In the Canary Islands, moderate trade wind will predominate, stronger in exposed areas.
Starting on Saturday, the front will move eastwards and leave instability in the Mediterranean area and the Balearic Islands, where heavy showers accompanied by storms and significant accumulations are expected, especially in the north of the islands. In the rest of the country, the skies will continue to be cloudy, but with a tendency to become clear in the afternoon in large areas of the center and south. The rains will be weaker in the west and are not expected in the interior of the plateaus. Snow will appear in the Pyrenees from 1,600-2,000 meters.
Maximum temperatures will drop in the north and east, and rise slightly in the rest, while minimum temperatures will tend to decrease in the northwest quadrant. The wind will turn to the north, with moderate or strong gales and winds in the northeast and the Balearic Islands, and very strong gusts in mountain areas and in the north of the Balearic archipelago. In the Canary Islands, the moderate trade wind will continue, with gusts of strong wind at some times of the day.
Sunday will show “the other side of autumn,” as Del Campo summarizes. It will be a generally stable day, although with some residual showers in the Balearic Islands in the early hours and the possible arrival of a new one off Galicia in the afternoon. Clear skies will predominate in much of the country, but this stable environment will favor the formation of fog banks in the interior and a sharp drop in night temperatures.
