The Aemet warns of the radical change in weather that arrives in Spain after the storm Bert: this is how the “omega blockade” affects

This has been warned by the State Meteorological Agency (Aemet), which already anticipates a week marked by the “atmospheric stability”the “absence of significant rains” and weak frosts that will be restricted to the northern interior of the peninsula. Starting this Wednesday, November 27, temperatures in our country “will rise for the rest of the week with highs above normal», as explained by the organization.

Following what Aemet indicates, it seems that an anticyclone will gain ground at least until the weekend, leaving behind the rainfall and low temperatures of these weeks. During this week, Spain is expected to be “predictably affected by an atmospheric pattern known as omega lock», as eltiempo.es also anticipates.

An omega blockade over Spain will bring a change in weather

Starting this Wednesday the 27th, temperatures maximums will rise again in many parts of the country for the anticyclone installed during the last few hours. During these days, and at least until the weekend, the thermometers will be “above usual” in almost the entire country, being high for the time of year in which we find ourselves.

During this week, we will have “great stability” in almost the entire Peninsula, which will in turn bring «predominance of sun and absence of rain». For its part, as Aemet has warned through its daily forecasts, in the next few hours the weak frosts They will be limited to flat areas of the interior-northern peninsula.

This situation will, in turn, favor the morning fog formation in areas of Galicia, in the valleys of the Tagus, Guadiana, Guadalquivir and in the southeastern interior. It is expected that these fogs can be dense and persistentalthough they could rise over time.

According to eltiempo.esto this situation will also be added a omega lockthat is, an atmospheric pattern can cause long periods of stability or instability and which occurs when a high pressure area is trapped between two low pressure areas. This will cause air circulation to block the normal movement of weather systems, moving away the fronts of Spain for a few days.

In the event that this blocking situation finally occurs, a week will be confirmed where stability be the absolute protagonist. However, it is expected that it will not be very durable and that extends only until Sundaywhen this anticyclone and the ridge will end up moving towards the east.

When does the winter cold return to Spain?

While waiting for the month of December to arrive definitively, it seems that for the moment the meteorological winter It is still far from our country. At least until Saturday, the dry and sunny weather continue to predominate in almost the entire Peninsula, with temperatures that will remain around 15 or 20 degrees at many points.

Looking ahead to the weekend, not many changes are expected, since the frosts that occur will be weak in almost the entire country, even in high mountain areas. It is expected that on Sunday, December 1, a drop in temperatureswhich will continue similar without rain or storms in sight.

Regarding what will happen in the coming weeks, it seems that the meteorological models indicate that the temperatures will continue higher than usual throughout Spain. According to Meteored, it is possible that “until the second week of December” “above average temperatures” are recorded in our country.
