Portugal will experience a “relief” from high temperatures: will it last long?
ONE heat wave who liked us for more than a week was to leave data and images for posterity: some have been exceeded thermal records located in certain locations in the northern interior of the country, such as Lousã and Pinhão, and, at the same time, Portugal found himself suffocated by a devastating wave of wildfires that razed thousands of hectares in recent days. Not to mention the Survival judged by scorched heat.
pressure to our country at altitude
However, the beginning of this week was organized with a few changes. The isolated depression at altitude positioned over and that in recent days the crested anticyclone has been sustaining, and consequently the transport of very hot air to the Peninsula, will approach mainland Portugal in the next few hours.
Thanks to fresher air coming from the Atlantic, temperatures have dropped considerably across the country today, with this decline being much more evident in the districts of Viana do Castelo, Braga, Porto, Aveiro, Coimbra, Leiria and Lisbon, in other words, mainly on the North Coast and Centre. They also dropped in the interior of the country, but they have something high in Trás-os-Montes, especially in the interior of Baixo Alentejo. This Monday the wind blew predominantly from the West, sometimes from the Southwestand occasionally with moderate to strong gusts.
ONE maximum period foreseen for today in a district capital of the Continent was 34 ºC for the city of Bragança, followed closely by Alentejo towns such as Beja and Évora. In addition, there are also conditions for the occurrence of light showers scattered across the Upper and Lower Minho early Monday night.
Tomorrow the weather will cool down again, covering more areas
For Tuesday it is expected that the small depression continues to progress, positioning itself between Galicia and Brittanyblowing very hot air towards the UK and other European countries. The temperature of temperatures will cover more areas, noting this cooling of the country in the North and Center of descentand the wind will blow from North/Northwest.
Thus, the maximum temperature will be below 30ºC in most of the district capitals, except for those contained by Beira Baixa, Alentejo and Algarve, which will overcome a minimum barrier of 30 ºCclimatologically normal for these regions in summer.
The night will be more bearable throughout the country as the minimum will no longer reach thermal values in the order of 20 ºC. It should be noted that, again, there will be a possibility of weak and scattered showersunevenly distributed throughout the western coastal strip, between the districts of Viana do Castelo and Leiria. It will last from midnight until almost noon.
The anticyclonic ridge will intensify during the second half of the week
Wednesday will be a transition day as the crest should strengthen again over the entire Iberian Peninsula.. In this way, temperatures will rise again, preventing maximum values of 39°C/40°C to the Center and South of the country (Castelo Branco, Portalegre, Évora and Beja). In the rest of the country time will determine, but rarely will districts with highs above the aforementioned 35 as well. The sky will be clear or slightly cloudy in east to east of mainland Portugal.
For Thursday, medium and high clouds are expected, although the dominant panorama of sky is clear. And then, yes, again the thermometer will indicate maximum temperatures close to or equal to 40 °C in the same areas, significantly, than the day before. It will be a hot day in the country, but we are not hot considering the summer.
Despite all the hot days with thermal values persist, despite all the care remains persistent, as well as the risk of forest fire persists, as well as the risk of forest fire.
Thus, all care must be taken, not only due to the fire risk that intense heat poses to human and animal health, but also to the danger of forest fire. It should also be noted that on this day dust from the Sahara will arrive in the country via the Algarve. They will expand to the north, covering the Alentejo Coast, Baixo Alentejo, Central Alentejo and parts of Alto Alentejo during the remaining hours of Thursday, Friday and Saturday.
And from Friday onwards, what will happen?
There is certainty of certainty for us at the moment between Friday and Sunday temperatures will again register high abnormal valuesespecially in the districts of Santarém and Castelo Branco and throughout the Alentejo region, It is predicted that the maximum that we can reach or ºC the 40. Also don’t forget the Nordeste Transmontano (Bragança) with thermal values very close to the aforementioned areas.
The prospects are not, for now, the best, given that this situation could extend until the beginning of next week. Despite the familiar warmth that he once lived in the country, he is no longer with us.
So for the second half of this week the “weather ingredients” responsible for the continental state will be the influence of the weather in mainland Portugal anticyclonic crestwhich favor the air subsidence, which heats up quite noticeably during the process. To this must be added stability and high insolation, typical of the summer season. In short, as much Portugal, like Spain, its own warmth in these conditions of stability.
