Skywatch: Severe storm warning today and tomorrow

BarcelonaThese past few days have already seen showers and thunderstorms in some parts of the country, and the unsettled weather will clearly worsen between today and tomorrow. A pocket of cold air will cross us at altitude, colliding directly with the summer heat we have at the surface and the humidity of the Mediterranean, causing a sharp increase in instability. This morning, scattered, minor showers may occur, especially in parts of the coast and the southern pre-coast. However, from the afternoon and into the evening, showers and thunderstorms may occur irregularly in many regions, especially in the center and north. Saturday will be the most complicated day, with a series of showers and thunderstorms that will primarily affect the south and inland parts of the country. In all cases, the storms could be strong and accompanied by violent meteorological phenomena, such as downpours, hail, and strong winds. Civil Protection has already activated the Inuncat plan alert.

More than 20 l/m² can accumulate in just half an hour. Meteocat has also issued alerts for heavy rain across much of the country between Thursday and Saturday, while the State Meteorological Agency (Aemet) has issued a special warning for the passage of this DANA, which will primarily affect the northern half of the peninsula, with heavy showers in this area.

Friday: busy weather

Cloudy patches will be present throughout the morning. Cloud cover will again be abundant along the southern coast and pre-coast in the morning, with scattered showers or light rain. Showers and heavy thunderstorms will begin moving south from the Pyrenees and Pre-Pyrenees starting around midday and continuing into the afternoon.

Until the evening and early night, the storms will affect many parts of the center and north of the country irregularly. Some showers may even reach the coastline starting in the evening. In the late afternoon and midnight, they will be concentrated between the West and Terres de l'Ebre regions. The storms will be accompanied locally by downpours, hail, hail, and strong winds.

All with temperatures that will generally remain unchanged, both day and night. Maximum temperatures will only drop slightly in the western part of the country and the Pyrenees. Another day of relatively warm weather, with highs of 26 to 32°C and muggy conditions on the coast. The night will be mild, with tropical lows on the coast and in parts of the pre-coastal, southern, and western parts. Cooler in the north.

Strong storms to start the weekend

Saturday will be the busiest day, as the cold air pocket will hit us hard. Showers and thunderstorms are expected throughout the day in practically every part of Catalonia and Castellón. It won't rain all day everywhere, but thunderstorms and thunderstorms will appear, often heavy and with the risk of hail, hail, or strong winds.

According to the current maps, the worst affected areas would be the south and west of the country during the early morning and early morning, but storms will reach all parts of the country throughout the day. All this with temperatures set to drop thanks to this rain and cloud cover. The heat is very much in check.

Sunday will be calmer and warmer.

Starting Sunday, the cold air jam will dissipate, and sunshine and calm will clearly gain ground. Only a few afternoon showers will remain in some mountain areas, especially in the Pyrenees and Pre-Pyrenees. Temperatures will rise again, and next week the heat will be much more pronounced. However, no major heat waves are in sight.

Summary of the recent downpours

A wave of thunderstorms hit early Thursday morning, affecting much of the Tarragona region and the southern tip of Ponent. The night was marked by lightning and thunder, with some local rainfall. The most notable rainfall was nearly 40 l/m² in Horta de Sant Joan (Terra Alta), 20 l/m² in Buda Island (Montsià), and 13 l/m² in Els Ports (Baix Ebre). This rain also reached the fire zone in Baix Ebre, aiding firefighting efforts. During the afternoon, downpours affected local areas of the Pyrenees, Pre-Pyrenees, and nearby areas of northern inland, with a notable rainfall of 8 l/m² in Castellar de n'Hug (Berguedà).

Furthermore, there was abundant cloud cover throughout Wednesday in the center and especially in the south of the country, where a few showers fell.
