The storms and the cooldown will return mid-week

BarcelonaThe week has started very calmly and with a rise in heat, although without reaching the extraordinary extremes of previous days. A mid-summer atmosphere with temperatures clearly above average, which this Monday pushed the mercury up to 37 °C in Vinebre (Ribera d'Ebre) or 36 °C in parts of the northeast, such as the city of Girona. Tuesday will maintain the same trend of radiant sun and heat, even with a few degrees more in some regions. But all of this will be transitory, as on Wednesday a cold front will cross us, which will cause a round of showers and thunderstorms in several regions, and a new and clear cooling with the arrival of the north wind. A rollercoaster of thermometers that will remind us that autumn is approaching.

Tuesday: sun and summer heat

We will wake up again this Tuesday with a cool morning in general, and more mildness on the coast, where some tropical minimums will be repeated only in some areas, especially in the city of Barcelona due to the heat island effect. Sun and calm will dominate everywhere without exception throughout the day, with only some local and harmless cloudiness in the afternoon in the Pyrenees.

The maximums will remain similar or rise a little more, although in the northeast they may begin to fall. Even so, the intense and summer heat will remain, with many values from 29 to 34 °C, but between 35 and 37 °C in Ponent and the Ebro valley, without ruling out locally some higher value in these sectors.

Weather change on Wednesday

The passage of a cold front will cause a change in the weather on Wednesday. Intervals of clouds will increase throughout the day, and from mid-morning and for the rest of the day, showers and storms will become more widespread. They will mainly affect any point in the Girona and Barcelona regions, locally with strong intensity and accompanied by hail or sleet. Meteocat has already issued the first warnings in these areas for heavy rain.

It will also rain in other areas of the Pyrenees and the Pre-Pyrenees, and from the afternoon or evening onwards, showers will also reach some areas of the south of Catalonia, but above all the Valencian Community and the Balearic Islands.

A change in weather that will reactivate the north wind at both ends of the country, and that will open the doors to a new and clear cooling. Therefore, thermometers will drop again, with less warm days from then on, and very cool nights, or even cold ones in mountain areas.
