Awaiting strong storms in many regions until dawn
Once the front passes, more calm is expected on Friday and a more marked freshening
BarcelonaThe change in weather that arrived this Thursday is leaving showers and strong storms in many regions. The downpour started around midday, mainly in the Pyrenees, and has been gaining ground. It is expected that until dawn, thunderstorms and showers will sweep across a large part of the country, also reaching the coast. In fact, in the last hours of the day, they will concentrate especially on the coast, pre-coast, and the northeast, where some downpours will occur. Where it has rained the most so far is in the Pyrenees and eastern Pre-Pyrenees, with very significant accumulations that have caused several incidents. Outstanding are the 84 l/m² in Sant Joan de les Abadesses (Ripollès), the 70 in the Santuari de Queralt (Berguedà), and the 67 in Montesquiu (Osona).
As has been happening in recent hours, some downpours may occur, locally accompanied by hail, sleet, or strong winds. The most affected areas will continue to be the eastern Pyrenees and pre-Pyrenees and the northeast. Meteocat maintains many counties on alert for heavy downpours that could leave more than 20 or 40 l/m² in just half an hour, and even 60 l/m² in three hours – a new Meteocat alert that debuts in this episode – in Ripollès, Osona, Lluçanès, Garrotxa, and Berguedà. The Inuncat plan remains activated in alert phase.
The precipitation will be moving offshore during the early morning, although until early morning there may be remnants of showers or drizzles on the northeast coast and in Tarragona. The north wind will blow strongly at the extremities, especially in Alt Empordà, and on Friday calm will dominate, with sun that will be gaining ground. Once the active front that is crossing us passes, the refreshment will be noticeable everywhere. The mercury will start rising again from the weekend, but for the moment without any heatwave in the medium term, and with great tranquility.
Friday: calmer and cooler
After the squall and storm front, calm will dominate this Friday. In the morning there will still be many cloud intervals on the coast, pre-coast and northeast, but the sun will gain ground from the west, extending to many places as the hours pass. During the night, early morning and morning, the tramuntana wind will blow strongly in Empordà, especially in Alt Empordà, where Meteocat has activated an alert for gusts exceeding 108 km/h. There will also be mistral in Ebre.
In the afternoon, cloud remnants will remain in the northeast and Ebre, with only a risk of some weak and scattered showers between the interior of the Girona counties and the north of Barcelona counties. Independently, instability will increase in the Valencian Country, with a risk of some weak and local showers.
All in all with a clear generalized refreshment. Colder mornings, and in the middle of the day the heat will be kept in check, with values quite normalized for the season. Many maximums of only 23 to 28°C are expected, locally higher in the Ebro Valley and Ponent. On the other hand, they will be shorter in mountain areas, with quite cool temperatures all day long.
Calm and warmer weekend
The first weekend of June presents itself as very calm and generally quite sunny. Saturday will have more remnants of cloud intervals than Sunday, and in the afternoons, clouds will grow in the Pyrenees which, at most, will leave some insignificant shower in this sector.
Temperatures will be climbing positions after the cooling down on Friday, both day and night. However, at night and in the early morning, coolness will still dominate, and during the day the heat will intensify, but it will be bearable and far from extremes in general. Many highs of 26 to 32 °C are expected, lower in mountain areas. Next week the heat will intensify.
