Heat ends, but storms arrive

by

The heat is being the undisputed protagonist of this week at the weather. However The warm episode He has his days (or his hours) counted in much of the Peninsula: as of today the extreme heat will live with rains and storms: some communities will have to alert for very different phenomena. Variopintos phenomena. Meteorologists foresee that the warm episode that affects the peninsula will fade in the next few days and that at the beginning of next week the instability will be the dominant tonic. The transition will not be simple: during the next few days some areas will see the arrival of rainfall and storms while others Taguada vs. dorsal. Let’s put some context to understand what is happening at the atmospheric level. A few days ago we saw an arrival of an Atlantic anticyclone and an associated dorsal. The dorsal are areas of high pressures that extend from a high pressures center lengthening the scope of anticyclonic time. The stability associated with high pressures, along with other factorscontributed to a high insolation that warmed the air of the peninsula until it brought us to the current situation. However meteorologists They announce now that a trough display in the next few days the dorsal. That is, from a situation we move on to the opposite, with a region of low pressures associated with a storm changing the meteorological panorama. A heat pause. And how this translates: then that instability will take possession of peninsular meteorology. Some areas will begin to see storms today, but it will be from Sunday, with the arrival of the dorsal, which these are generalized. Heat warnings and storm warnings. The peculiar transition between two weeks marked by opposite phenomena will leave A singular notice map of the State Meteorology Agency (Aemet), a map in which yellow and orange warnings coexist due to maximum and storm temperatures (and also yellow notices for rains). In this sense, today it will be the most unique: 14 autonomous communities (all peninsular except Murcia) will see active notices throughout the day. Of these highlight orange notices due to temperatures of up to 40º Celsius in the Sevillian countryside; and orange warnings for storms inside the Cantabrian cornice, from the Asturian southwestern to the inner Bizkaia. In unknown terrain. Spring is a transit station where changes in the atmospheric situation are not entirely strange. However, we can talk about an anomalous season in terms of meteorology: from a drought we spend some of the months with more rainfall than we have record. Now we return to one more panorama in the tonic of recent years: with a summer that is advanced leaving us extreme heat during the last week of May. To know what will happen during the real summer we will still have to wait a few weeks. In Xataka | The reservoirs are almost 22% above the average of the last decade.

The persistence of the blockade in the middle of May brings us storms and a lot of uncertainty

by

In recent days, a Dana has been affecting a good part of the peninsular territory. And, even if it seems, the news is not that it will continue with us “favoring the development of intense and organized storms.” Will do it (As of Tuesday, “Depression will tend again to descend on latitude in an erratic and retrograde movement, approaching our geography”); But that begins to be the least. The most thing is that, for the umpteenth time, A persistent blocking pattern It continues to hinder the zonal circulation. A puzzle called “Spring of 2025”. As Sergio Escama explains in detailcurrent instability is due to three weather pieces: The anticyclone of the Azores that, despite being placed in its usual place, continues to have a strange elongation to the north (a kind of slide) that allows the arrival of Atlantic storms to the Peninsula. A dorsal that from Central Europe attracts the entire continent and arrives at the British Isles A continuous transfer of low pressures that passes between the two anticyclones and reaches our latitudes. Time-out! However, the next two days will be more stable and temperatures will tend to rise. Of course, the minimums will continue lower than normal and should not surprise us if we find frost in mid -May. But in a matter of days, the situation will become complicated again. Because, as I said, the Dana that now seems to get away will start going down back to us And, predictably, it will form a system with another that ascends from southern Africa. That is, between the Tuesday and Thursday a significant increase in stormy activity is expected. In fact, due to uncertainties associated with this type of phenomena, agencies are preparing: storms can be strong and t could affect any point in the country. Of course, the center, the north and some parts of the west of the peninsular territory They will take the worst part. What can we expect? In addition to low temperatures, What we are going to see They are storms (some very intense) that will cause rays, storms and hail. But that is in the short term, in the long term no one is very clear about what will happen. We are in a year in which many areas have seen rains as they did not see since the beginning of the records. March, as we know, has been One of the rainiest since 1961. The interesting thing is that May will also be above the average and nobody knows how all this will affect summer. So we enjoy it and cross our fingers so that this is not an anecdote, but a change of trend. Image | Tropical tidbits In Xataka | Spain has received more rain than ever this spring. And yet it is unable to get rid of the ghost of the drought

The good news is that the storms will finally give us truce this week. The bad is that time will remain unstable

The last weeks have been marked by instability: rains (we have seen One of the most wet that remember the records), cold and storms several have been protagonists in this spring. Now, after the holiday period, experts foresee a change in the atmospheric trend. Changes, in theory. This week will be A week of changes at the atmospheric level with respect to the dominant trend during Holy Week. Of course, at ground level these changes will be noticed rather: instability and rains will continue to accompany the day -to -day life of many Spaniards, although in some areas the increase in temperatures can take the thermometers towards the 30º towards the end of the week. No storms in sight. Meteorological forecasts for the next few days foresee a change in the atmospheric pattern: the storms disappear for the peninsular geography, opening the way to the major influence of anticyclones such as the Azores. According to the forecast of the State Meteorology Agency (Aemet), this will be reflected in an increase in maximum temperatures in the southeast peninsular interior, as well as in mountainous areas of the north. However, this is only part of the story. A tape tall It will become the protagonist In these first days of the week, accompanied by a front that will bring new rains to a good part of the Peninsula. In practice. The Aemet forecastwhich throughout the day will extend to much of the northwest peninsular half, being able to reach areas of the southeast. The forecast also speaks of possible snowfall in mountains of the north end. On Tuesday, instability will increase, with “showers and storms that can be locally strong in areas of the northeast peninsular near the Mediterranean.” If Monday temperatures are experiencing a slight rise, the situation will be reversed tomorrow in some areas, with a notable decrease in the maxims in the Ebro, the east of the Northern Plateau and the Eastern Cantabrian, according to the agency’s forecasts. A more palpable change. As of Wednesday, the change in the atmospheric state could materialize in a change over time. The models foresee that this day the influence of the Azores anticyclone will stabilize the meteorology of the peninsula. The heavens, yes, will remain overcast in the north, with rainfall “weak although persistent”In the area. The showers are not ruled out in the rest of the peninsular territory either. Round of the rains? The situation is expected on Thursday but Friday could see the arrival of A new trough and, with it, the return of rainfall of greater consideration. If the forecasts are fulfilled, this phenomenon will move west throughout Friday and Saturday, leaving rains and even storms.

In the middle of a huge “train of storms”, AEMET has just pronounced the most anticipated word of winter: snow

by

The rain no respite and he’s not going to give it. Neither the rain, nor the winds, nor the snow. While the storm Herminia full of red notices the entire northwest part of the peninsula, the forecasts have us all looking at an Atlantic full of surprises. Among them, snow. What Herminia is doing. In recent days, the entire country has been revolving around Herminia. In some regions (such as Galicia) the intensity of the winds forced to divert flights and cancel trains. The worst, however, had not yet passed: this Monday will be the strongest day of the storm. 16 autonomous communities They have notices from the AEMET. Until Tuesday, Herminia will unfold a temporary more than considerable with wind, waves, rain and snow. But, as we said, Herminia is nothing more than the appetizer. According to predictive models, two new storms are going to cross the peninsula. The first will make its debut on the same Wednesday. In fact, on Tuesday a very cold air mass of polar origin will begin to enter the country. We talk about “temperatures at about 5500 meters altitude (500 hPa)”, explained Sergio Escama in Meteored. But the interesting thing is that we will notice it down here. What will we notice? The winter. Winter in its meteorologically pure state. From Wednesday the general drop in temperatures will be evident and snow will affect to the Cantabrian Mountains, the Pyrenees, the Central System, the Iberian System and other inland areas. The snow level is not clear yet, but is expected to be low. And that will be only the first of the post-Herminia storms. Because, according to AEMET modelsafter a very entertaining Wednesday-Thursday with the snow (and its problems); A busy weekend will follow. That is, the “storm train” extends as far as we can reliably see. This precision is important because, although right now there is a possibility that this second storm will be more intense than the previous ones, the time frame prevents us from being able to estimate its virulence accurately. What can we do? Luckily, The recommendations for now are the same: avoid unnecessary trips; prepare for the cold, wind and snow; and pay attention to weather and civil protection updates. We already know that this is one of the great paradoxes of snow: it is something as wonderful and fascinating as it is full of problems.
