With no rain in sight, the anticyclone “commands” in Portugal: until when?
In the last few hours there is an outbreak that predominate in the anticyclonic environment in a large part of the country. In Madeira, the sky has darkened and there are some light showers in several parts of the Island. Even in the south of mainland Portugal, but in an extremely residual and incredibly dispersed way, some drizzles fell in the Algarve region. This meteorological instability arose thanks to a cold air bag at altitude which will increase in the coming days in the Autonomous Region of Madeiraand also in the Canaries (Spain).
a referral cold air bag is reflected to the surface in the form of showers in Madeira, which will dissipate over the weekend. In fact, in about 72 hours, this Archipelago could add up to at least 16 liters per square meter. Not being anything significant, at least it contrasts with the severe drought in which mainland Portugal is plunging meteorological.
In this sense, the scarce which appeared in a very residual way in the south of the Continent (Baixo Alentejo and Algarve) both on Monday (24) and today (26), Will download again in the next few days. Until Sunday, as temperatures registering oscillations without Continent. In addition to the sunny, dry and cold environment, the Tagus to the South like suspended dust of the Sahara Desert can become the hue of the sky minimized whitish.
At the end of the week the showers will even dissipate from Madeira and the smaller ones will follow us at least the first days of February.
As for the Azoresan archipelago that registers a very variable time, there will be some showers and strong wind until Sundaybut nothing extraordinary.
An anticyclonic blockade that seems unbreakable, until when?
On the other hand, absolutely anticyclonic weather and stability will continue to be the protagonists in mainland Portugal.. Most likely this situation will drag on until the early days of at least according to our trust model (ECMWF).
Definitely, The anticyclonic blockade will persist for a while longer, controlling the sun shining in a large part of the country. YOU fogs will appear, sometimes persistently, in the inland valleys – Nordeste Transmontano and Beira Alta – as well as the morning frosts which in some cities, as a result of negative minimums, will be intense in cities such as Vila Real, Bragança, Guarda and Covilhã.
This is the “perfect cocktail” for triggering situations problems such as the aforementioned meteorological droughtterrible for the agricultural activity or for the prevention of forest firesor even The risk from natural phenomena such as thermal inversion.
