Change of season, but not of weather: autumn also begins with heat

At 02:05 a.m. we officially entered the astronomical autumn. We are changing seasons, but not the weather, since, although we are waking up to cool temperatures in general, today will remain warm with summery air and radiant sun in the middle of the day. An anticyclonic calm that will accompany us for a few more days, as no significant changes are seen until at least next week. Therefore, we will continue for many more days with thermometers above average. Yesterday, summer said goodbye with temperatures that again exceeded 30 °C in many regions, especially in the northeast and inland. In fact, in the interior of the Ebro, temperatures were around 35 °C for another day.

Wednesday: sun and heat

The first morning of autumn starts with a cool atmosphere in general, and a bit milder on the coast, where some slightly tropical minimums have been repeated, especially in the city of Barcelona due to the heat island effect. In the middle of the day the heat will intensify a little more again, although in the Ebro the thermometers will drop. Many maximums of 27 to 32 °C are expected, locally a little higher in the southern interior and in Ponent. A first day of autumn that will be hot again.

The sun and calm will dominate with very few nuances. Only some low clouds or morning mists may repeat in inland plains and the pre-coastal area, as well as some decorative brushstrokes of thin clouds.

Few changes until next week

The rest of the week will continue to be marked by the powerful anticyclone that embraces a large part of Europe. This will translate into days of absolute calm and radiant sun, with very few nuances. No rain is expected anywhere. Temperatures will rise further and will experience a new peak between Friday and the weekend, with summer heat and values clearly above average.

However, the maps are confirming significant changes for the coming week. The anticyclone will gradually leave and instability will increase, which could lead to several rounds of showers at any point, as well as a general cooling. There are still days to go, however, and all of this will have to be confirmed.
