More heat and strong storms during the afternoon

BarcelonaThe latter part of the weekend will be marked by more unstable weather. The entry of some cold air from the upper layers of the troposphere will cause powerful storm clouds to develop, especially during the afternoon in the northern third of the country. Meteocat has issued a warning for heavy rain, with showers that could accumulate between 30 and 40 l/m.² in less than half an hour, accompanied by hail and hail. The regions most likely to experience the heaviest showers are Berguedà, Ripollès, and La Garrotxa.

Powerful storm clouds will again form off the coast during the next morning, with the potential for further storms. Early tomorrow, they could affect parts of the central coast or the Tarragona coast.

Sunday: Cloudy on the coast, warmer weather in the West, and storms in the afternoon

The weather will become more unstable, but this will occur during the second half of the day, when cold air will enter the middle and upper layers of the atmosphere, resulting in the formation of showers and thunderstorms. Early in the morning, cloudy skies will appear along the coast, and we will have some showers offshore or, locally, in parts of the central coast or the pre-coastal region. By mid-morning, the skies will clear up and there will be more clear skies. Over the rest of the country, however, the morning will be calmer, and from midday onwards, cloud cover will form and thunderclouds will form in the northern half of the country and inland regions, where irregular showers will occur. Storms may affect inland areas of the northern half of the country, the pre-coastal region, Central Catalonia, the regions of Ponent, the Pre-Pyrenees, and the Pyrenees. Rain is also possible in the central and southern Pre-coastal region, as well as in Els Ports and the interior of the Ebro River. Rain is less likely along the coast, where it will be cloudy but not rainy.

Temperatures will rise slightly further and could exceed 35°C in Ponent, with a warm atmosphere but not the extremes of last weekend. Elsewhere, temperatures will range between 31°C and 33°C, while along the coast they will be around 30°C, with a more muggy feeling.

Monday: Calm morning with showers in the afternoon

We'll start the week with few changes, with a clear morning and cloudier skies in the eastern half, where a few showers are possible, especially from midday onwards. Temperatures will rise slightly further in the West and inland Terres de l'Ebre, where they will reach around 37°C.

Next week: with an eye on a possible DANA

Midweek we will be on the lookout for the arrival of a pocket of cold air at altitude associated with the ex-hurricane Erin, This could trigger atmospheric instability again. Weather models predicted it would reach our country a few days ago, but now it appears it will be held back in the western Iberian Peninsula and not cross the Iberian Peninsula. However, what is clear is that instability will increase, and we will once again experience showers and thunderstorms, locally of some intensity. Temperatures will drop starting Wednesday, with a generally cooler atmosphere.

We'll be monitoring it!
