With two days left until the official arrival of astronomical autumn, we still have to talk about temperatures more typical of summer than of these dates. Minimum temperatures have recorded the typical drop in recent days due to the shortening of daily daylight hours, with a significantly cooler environment at night and in the early morning, especially inland and in the Pyrenees. Maximum temperatures, on the other hand, continue to rise. Yesterday they climbed back above 33 ºC in the interior of the Ebro and in the Priorat. And this Monday there will be a heat peak, with many maximums of 30 to 35 ºC throughout the country. Although the mercury will fall back a little on Tuesday, temperatures will remain above average throughout the week, along with anticyclonic calm.

Yesterday, remnants of instability were still seen in some sectors of the territory. In the morning, some downpours falling over the sea brushed the coast of Barcelona and left some local showers and, even, some isolated flooding in the seaside neighborhoods of the Catalan capital itself, where in a few minutes more than 10 or 15 l/m² accumulated. They were very local and anecdotal phenomena that ended up clearing away completely.

The weather has clearly improved over these last few hours, leaving behind Wednesday's heavy storms and downpours. However, instability has persisted, with frequent cloud intervals and remains of some scattered, local, and weak showers in parts of the coast and pre-coast –especially in Barcelona– and in the northeast. It is not completely clear yet, and this situation will repeat today, without ruling out some very local morning downpour by the sea, as has already happened this morning in the seaside neighborhoods of the city of Barcelona, where localized flooding has occurred. In some neighborhoods, locally, more than 10 or 15 l/m² have been exceeded in a few minutes due to these showers over the sea that occasionally brush the coast. All this with heat that will remain very much in check and cool nights. Over the weekend, the sun and calm will finally prevail completely.

The episode of showers and heavy storms in the last few hours has left authentic torrential downpours and records that, locally, have brushed or exceeded 100 l/m², most of them falling in a short time. The thunderstorms affected the northeast in particular during the afternoon, with some downpours accompanied by hail or stones, as was the case in the city of Girona itself. 50 l/m² were reached or exceeded in some cases. But the main event arrived in the evening and at night, when the showers and storms gained strength and extent on the coast and pre-coast of Barcelona and nearby areas, such as Central Catalonia, as well as in the Valencian Community and the Balearic Islands. In regions such as Barcelonès, Vallès Occidental, Baix Llobregat, Garraf, and Alt and Baix Penedès, the rain was falling for hours, with moments of torrential intensity and many lightning bolts and thunder. All this caused floods and many incidents, such as the closure of the Ronda de Dalt in Barcelona and the death of a man dragged by a stream in Garraf. In addition, in the Valencia area, the rain has also caused havoc (you will find all the data and images of the episode at the end of this information).

The sun, the calm, and the intense heat of the last few days are numbered, as this Wednesday a cold front will cross us, causing a notable change in the weather. It will be mainly from the afternoon until the night when downpours and storms will gain extent, especially in the Girona and Barcelona regions, in the Pyrenees and the Pre-Pyrenees. They may discharge with strong intensity and leave some heavy downpours. The north wind will strengthen at the ends and throughout the day temperatures will go down. We are at the gates of a new and clear cooling that in the coming days will bring back the air of the beginning of autumn.

We are leaving behind a very stable weekend, with the sun in almost absolute control and temperatures that have risen progressively, both at dawn and during the central hours of the day, with controlled but more intense heat than in previous days. In fact, yesterday temperatures already brushed 35 °C in Ponent and inside the Ebro valley. A situation that will be repeated at the beginning of this week. Between today and tomorrow there will be a transient peak of heat, with maximums between 34 °C and 37 °C in the warmest areas of the interior. But all of this will be short-lived, as from Wednesday a new change in the weather will arrive that will bring more showers and a new clear drop in thermometers.

The weather remained very stable this Saturday, with some intervals of harmless clouds and a practically absolute dominance of the sun. The temperature rose even more, both at dawn and during the central hours of the day, with controlled but more intense heat than in previous days. In fact, it already brushed 33 °C in the West and in the interior of the Ebro valley, a situation that will be repeated this Sunday, which has begun with generally warm temperatures.

We have left behind a very peaceful and radiant National Day of Catalonia and we are entering a weekend that will continue to be marked by fresh mornings, mild midday temperatures, and sun, although with some nuances in the form of intervals of clouds. At the beginning of next week, we will have a transitory warm peak, but subsequently, we will experience a new drop in temperatures and a possible new episode of showers.

We are in for a very pleasant, radiant National Day of Catalonia to take advantage of, with very few nuances. Temperatures will remain normalized, with plenty of morning coolness and bearable heat kept in check during the middle of the day. Therefore, and as already happened this Thursday, 30 ºC will only be reached or slightly exceeded in parts of the south and in Ponent. The weekend will be similar, with small changes on Saturday, but quite calm and sunny in general. Thermometers will rise slowly, both by day and by night, but always far from extremes. At the beginning of next week we could have a transitory warm peak, which would not last long. We have set our path towards autumn, and, except for transitory peaks, there is no sign that would make us think of a return of extreme summer heat.

Yesterday's rains are now history. From today on, the sun and calm will return to dominate, with north winds still in the extreme areas. But pay attention when you leave the house first thing in the morning, as the air is suddenly cooler everywhere, and even cold in mountain areas. A good sweater is needed to start the day in many regions, while on the coast there have been no tropical minimums recorded anywhere for the first time in a long time. And even though the maximums will rise after Wednesday's thermal drop, the heat will be kept at bay and normal for the dates throughout the week at midday. Therefore, today we are noticing the first airs of an autumn that, now yes, is already approaching. Let's take the opportunity to open windows and cool down the houses. Summer is leaving and the historic heatwaves will not be repeated.

The announced change in weather is now here, which will mark the end of this episode of intense and atypical heat that has accompanied us during the first week of September, with temperature records. The passage of a cold front will complicate the meteorological situation and will make today an unstable day, with irregular downpours and storms that may be intense and leave some torrential deluges, with a risk of local flooding and sudden rising of rivers and streams. The area most affected will be the coast and pre-coast of Barcelona. The clash between cold air at high altitude and the intense heat accumulated over so many days can leave very significant downpours, which is why a large part of the country is on alert for intense rain. In fact, between the early morning and the first hours of the morning, heavy rain has affected the Garraf, the Baix Llobregat, the Penedès, and the north of the Vallès Occidental and Oriental, with a lot of electrical activity. Even so, the precipitation has moved quickly and has not left large accumulations for the moment. For example, more than 20 l/m² have already accumulated in a short time in Cunit, in the Baix Penedès.

The atypical and historic heat that has accompanied us at the beginning of this month is numbered, with weather that will already start to change on Tuesday and a temperature that will begin its descent in some points. It will be on Wednesday when we will notice the change in weather, with intense rain, wind, rough seas, and a lower temperature everywhere, with an environment more typical of the meteorological autumn.

The nightmare of this atypical and historic heat is numbered. This Monday we will no longer reach 40 °C in the Ponent area, although it will still be very hot. The drop in the thermometer will be slight, around 3 or 4 degrees in some places, enough so that no more records are set. However, it will still be hot, with highs around 38 or 39 °C in Ponent and in the interior of the Ebro. From this Sunday it is worth highlighting new exceptional values, not at all common in the month of September, such as 42.5 °C in Vinebre and 42.3 °C in Torroja del Priorat.

The temperature rose clearly yesterday Wednesday, when it exceeded 35 °C in many inland points and new heat records were registered in a month of September, as in the case of the Fabra Observatory, where the 33.6 °C measured is the highest value since 1914. All of this is the prelude to an exceptional heatwave that will cause the temperature to be well above the climatic average, with forecasts of registering new temperature records in the coming days.

Meteorological autumn began on Tuesday with very calm weather, dominated by the presence of clouds that, from midday onwards, gained ground, although they did not leave any precipitation. The mercury relaxed a bit, with maximums of 32 ℃ or 33 ℃ where it was hottest, but from this Wednesday onwards the situation will reverse and the temperature will rise notably. We are expecting a second half of the week with thermal values well above the climatic average for early September, with no significant cooling in sight.

Mercury again exceeded 35 ℃ this Monday, as it did over the weekend, but in general the temperature remained around 29 ℃ to 33 ℃. These are typical values for the end of August that will also accompany us into early September, with heat that could intensify more from mid-week. On the horizon there is no early autumn rain storm, but also no extreme off-season heatwave.

The mercury rose above 35 ℃ again this Sunday, after a fairly cool night everywhere, although less so than Saturday. The temperature will remain with few changes this week, with controlled heat, without excesses, and the weather will also not experience significant changes. On the horizon there is no early autumn storm, but neither is there any out-of-season heatwave.

Mercury once again exceeded 35℃ this Saturday, after a quite cool early morning everywhere, even on the coast, a situation that will be repeated this Sunday. The week will end with a very calm day with no new developments, marked by a temperature that will tend to rise progressively and by a sun that, although it has already lost many minutes compared to the end of June, is still the protagonist.
