Uncertain and changeable weather, with new showers

BarcelonaThe weather situation is uncertain, with some cold air aloft and a cold air pocket (DANA) over the Gulf of Cádiz. All of this makes the environment unsafe. Although the most severe instability is far from our territory, here in Catalonia we will continue to have the possibility of further showers.

The models indicate precipitation throughout the day, especially in the morning in the south of the territory. In these early hours of the day, small amounts of about 1.4 l/m were accumulated.² in Mas de Barberans and 0.3 l/m² in Aldover. Temperatures will rebound on Tuesday, but will drop later in the week and become somewhat cooler across the country.

Yesterday's storms were notable in La Garrotxa and Ripollès, often accompanied by hail and lightning (you'll find the most significant cumulative records at the end of this report).

Monday: Rainy morning in the south and new, heavier downpours in the afternoon in the north.

We'll start the week with a cloudy morning, with bands of stratified clouds moving in from the south and west. Light drizzle or showers will fall in the south during the morning, moving toward the pre-coastal area. Rain will also eventually fall in the West. However, only a few thin clouds will appear in central Catalonia and the Pyrenees, leaving no precipitation. This precipitation will be accompanied by mud due to an outbreak of dust from North Africa. This is a bad day for hanging clothes or parking your car on the street.

The temperature will cool slightly in the West, falling below 32°C. Elsewhere, it will hover between 28°C and 31°C. The muggy atmosphere will persist on the coast. In the Pyrenees, temperatures will rise to 28°C in the valleys, but will drop during periods of showers, and the atmosphere will cool down where it rains.

During the afternoon, the southern drizzle will disappear, and dark clouds will appear in the north of the country. Showers will fall in the Pyrenees, the Pre-Pyrenees, the northeast inland, and Els Ports. Locally, showers may be intense and accompanied by thunderstorms.

From midweek: more instability and new storms

Midweek, we'll be watching for the arrival of a trough associated with an Atlantic low, bringing cold air aloft and once again triggering atmospheric instability. Showers and thunderstorms are expected, locally of some intensity. In fact, the weather models indicate widespread precipitation across the west, the Pyrenees, and central Catalonia, with some downpours along the coast between Wednesday and Thursday, as well as in the pre-coastal area. Temperatures will drop starting Wednesday, with a generally cooler atmosphere. We'll be monitoring this.

• Olot: 9.5 l/m²
• Nuria: 8 l/m²
