On Saturday, September 5, Spain will face a day of contrasts. The heat will continue to dominate the interior, but the approach of a dana from the west will open the door to afternoon storms in the northwest. The difference between the capitals and the north coast It will be notable: Zaragoza will reach 41 degrees, while A Coruña, Oviedo and Santander will remain at 29, 29 and 26.
The maximum temperatures will reach 40 degrees in Badajoz, Lleida and Pamplona, and 39 in Córdoba. Huesca, Cuenca, Granada, Ourense, Teruel, Toledo and Valladolid will reach 38, within an interior band that will continue with very high values. The heat will concentrate in the depressions from the southwest and northeast, although it will also reach points in the archipelagos.
At night, the minimum temperatures will rise in many of the plateaus and will favor tropical nights in large areas of the Peninsula, except in the north. In the Canary Islands, the Mediterranean coast and the southern Atlantic valleys, some points could remain at 25 degrees. Night rest will be conditioned due to unusual temperatures for the time.
Northwest Instability
According to the prediction of the State Meteorological Agency (AEMET), the approach of a dana from the west will increase cloudiness and make the evolution clouds grow during the afternoon. The focus will be on Galicia, Asturias and the northwest of Castilla y León, where showers can be strong and accompanied by hail. The greatest intensity is expected in the extreme northwestalthough the rest of the Cantabrian Sea and Extremadura are not left out either.
In general, precipitation will be low. The storms may leave very strong gusts of wind, especially near the convective nuclei, and their distribution will be irregular. The prediction includes heavy showers in the extreme northwest, while in the rest the rain will be more scarce and localized. The risk will depend on the path of each storm and its development in each area.
Calima, minimums, winds
In the Balearic Islands, slightly cloudy skies will dominate, while the Canary Islands will have medium and high cloudiness and some isolated showers or storms in elevated areas. The AEMET report includes morning mists and fogs in the Strait, Alborán, the lower Ebro, Galicia and the Cantabrian Sea, as well as light haze in the west of the peninsula and the Canary Islands. Visibility will be more irregular during the first hours in those areas.
The maximums will rise in the Canary Islands, the coasts of Alborán, the north of Galicia and the extreme southwest, but they will fall in the Cantabrian Sea, the center and the southern half. The agency expects more than 35 degrees in much of the interior and locally on the islands. The persistence of tropical nights will be especially likely in the Mediterranean, the Canary Islands and the southern Atlantic valleys. The heat map will retain large regional differences.
The wind will complete the picture. The trade wind will blow in the Canary Islands with strong intervals and possible very strong gusts; The Tramuntana will affect Ampurdán and Menorca. On the northern coasts, Alborán and the Strait, the east will predominate, with strong intervals in the latter. In the rest it will be weak, with southern and eastern components, and will worsen in the afternoon in inland areas. The day will combine persistent heat and localized storms in the same territory.
