Atlantic storm remaining cool weather, rain and thunderstorms to Portugal
Over the past weekend, the depression located west of mainland Portugal and which affected the Azores and Madeira Archipelagos, rising an increasing part. This means that we are exposed to a flow of southwest wind at altitude with enormous divergence at high levels of the atmosphere and, therefore, favorable to development (risky) for areas of convection where other factors and development must be considered for areas of convection.. This special-in the mountain areas of NorteCentro especially of the country.
The one-week cold training in isolated Portugal, with the implementation front, will take place, the one-week implementation in mainland Portugal, etc.
On the other hand, it will completely close off its circulation, creating an isolated insulation system. On the surface, a cold country with some united fronts during the week, with no effect. With this meteorological panorama it will be important in the regions, and quite significant, especially in the Center. The South was also conditioned, albeit to a lesser extent. It should be noted that this weather state has the potential to last all week.
During these first days of the week, the fronts will touch land in mainland Portugal firstand also in Galicia (Spain), generating a very dense cloud cover and heavy rain. Until the end of Wednesday, it is expected that the areas with the largest accumulated district will be the districts of Braga, Porto, Aveiro and Coimbraespecially for Baixo Minho.
In a much more irregular way, it is also the occurrence of rain more intermittent and dispersion, recommended from thunderstormsnorth of Mondego, mainly inland and particularly in the areas around the mountains (as they belong to the districts of Aveiro, Viseu, Vila Real, Bragança). They will be less likely the further south. A big part of the decision – will fall between Tuesday (May 31) and Wednesday (June 1)and the probability of occurrence of thunderstorms will also be greater on these same days, in the aforementioned areas.
Mainland Portugal cooler than usual for the time of year
The position of the depression to the west of ours is stimulating the entrance of wind from the South quadrant, with a particular tendency towards the Southwest. The crossing sent by wind from the Atlantic, as well as the thick cloud coverare currently contributing to the notorious and widespread air temperature in mainland Portugalgiving rise to a slight negative thermal anomaly (weekly thermal values a little lower than normal for the time of year) which will last for most of the week.
For example, for Thursday, June 2after two stormy and rainy days (Tuesday 31 May and Wednesday 1 June), A maximum temperature of 21 ºC is expected in Porto, Lisbon and Viseu. It will not reach 20 ºC, in Faro 23 ºC, and in Coimbra and Santarém à Guarda there are no ºC. In Beja it will reach 26 ºC.
Azores and Madeira will also be conditioned by the so-called nalantic depression for almost the entire week, expecting good periods of rain, with wind, sometimes strong, and gusts of a maximum of 80 km/h on the Azorean islands. The tendency will be, in both Autonomous Regions, for the gradual lessening of instability at a daily pace, with room for cloudy periods. Until Friday, the maximum temperature will be 21ºC in Ponta Delgada and 22ºC in Funchal.
And on the weekend?
This weather situation could last at least until Saturdayalthough with a increased uncertainty in forecast. The most progressive is the isolated low in altitude, reflecting in a stabilization of the weather in our country.
Therefore, the province in mainland Portugal is expected to decrease considerably from Thursday, as well as the presence of clouds. It is expected that the temperatures continues relatively below averagewith southwest wind until Saturday. From Sunday, there is a potential change in the wind flowwith the same being able to eventually blow from the quadrant North.
