The next change of weather will arrive at the doors of May Day
A pocket of cold air will approach, which will increase instability by mid-week
BarcelonaWe have started a new week in the same way we finished the weekend. Therefore, sun and calm have dominated in most regions, with intense heat for the season that has left maximums around 30 ºC in Ponent and in the south. But afternoon showers and storms have repeated in the Pyrenees, Pre-Pyrenees, northern Catalonia Central, and northeastern interior, with some downpours and hailstorms that have left very local records of up to 60 l/m² in Montesquiu (Osona), 43 in Olot (Garrotxa), 41 in Pantà de Sau (Osona) or 35 in the Santuari de Queralt (Berguedà). And in the coming days some changes will arrive. On Tuesday, showers will lose extent and will concentrate more towards the Pyrenees and Pre-Pyrenees, but clouds and suspended dust will increase in the south. And between Thursday and Friday, instability will increase due to the arrival of a small pocket of cold air, coinciding with the start of the long May Day weekend.
Tuesday: more dust in suspension
On Tuesday there will be some changes in the weather. Sun and calm will dominate in the morning, with some low clouds or morning fogs in inland plains and hollows and on coastal stretches, especially from the Ebro. The novelty will be that in the afternoon, cloud intervals and dust in suspension will increase in the south of the country. On the other hand, afternoon showers will be less extensive and intense than on Monday, and will be concentrated in the Pyrenees and Pre-Pyrenees. Some will also reach the south of the Valencian Country accompanied by mud.
Regarding temperatures, minimums will drop a bit overall, and maximums will also recede a few degrees. Even so, thermometers will remain high for the dates, with warm weather in the middle of the day. Many maximums will range between 23 ºC and 28 ºC, locally higher in the west and south.
More showers in sight
On Wednesday, the situation will be similar to Tuesday's, with variable skies clouded by the presence of suspended dust and bands of clouds. Showers will repeat in parts of the Pyrenees and Pre-Pyrenees, but some may now reach the south of the territory, always accompanied by mud.
Between Thursday and Friday, maps indicate that a small pocket of cold air would detach from central Europe and affect part of the Iberian Peninsula, including Catalonia. Therefore, instability will increase coinciding with the start of the long May Day weekend, but it is not clear what its scope will be in our country.
Different meteorological models indicate that most showers and storms will be concentrated in the northern half of the country, and will also reach the coast, locally with some downpours. But it could also rain in other areas of the territory. A situation that is still uncertain and that we will have to specify and follow very closely, as depending on the final position of this pocket of cold air, we will have more or less instability.
