Awaiting the sky in various counties this long weekend

BarcelonaWe are on the eve of a long May Day weekend that is typically spring-like, with instability and a lot of variability. Therefore, the saying will be fulfilled: in May, every day a shower. The influence of a small cold air pocket will facilitate the growth of powerful clouds that will leave storms and irregular showers in various regions, especially in the northern half of the country. Where they fall, some local downpours may occur, occasionally accompanied by hail or sleet. In fact, this Wednesday we have already had the first scattered showers or mud drizzles, with a variable sky or hazy due to the passage of cloud bands and the presence of suspended dust. Temperatures have remained and will remain high for the dates, although they will tend to drop over the weekend.

Thursday: more storms

The sky will remain changing and variable due to the presence of suspended dust and the passage of cloud bands on the last day of April. Already in the morning, drizzles or some weak and scattered showers may fall, especially in the interior, on the southern face of the Pyrenees and the Pre-Pyrenees. Little for now, waiting for the clouds to grow with enthusiasm and, by the afternoon, leave irregular showers and thunderstorms in the Pyrenees, Pre-Pyrenees, Central Catalonia, the Ports area, and in parts of the pre-coastal region.

Locally there will be downpours of water that may be accompanied by hailstorms or some hail. Meteocat has activated the alert for intense rain that could leave more than 20 l/m² in just half an hour in several counties.

In the rest of the country, variability will continue, with less risk of showers, especially on the coast, although some may fall at the end of the day on the Costa Brava and in Ponent. All this with temperatures that will rise slightly, both minimums and maximums, with cool or mild mornings, and warm afternoons. Many maximums will range between 23 and 28 °C, but where it rains, it will cool down suddenly. In addition, the water will be accompanied by mud.

Each day a ray

Friday –a holiday, May 1st– instability will persist, with new showers and thunderstorms mainly affecting the Pyrenees and western pre-Pyrenees, but also other mountain areas and the western half of the country. Over the weekend, uncertainty is at its peak. Depending on the final position of the cold air pocket and the more or less active arrival of a front, precipitation distribution will vary from one place to another.

With current maps, it could rain in many regions on Saturday. A front of showers and thunderstorms would arrive from the west, mainly affecting the regions of Lleida, Tarragona, Pyrenees, and pre-Pyrenees, leaving most of the regions of Barcelona and Girona somewhat on the sidelines. And on Sunday, it wouldn't clear up, with new scattered showers. A situation we will have to follow closely, as many people have plans to take advantage of the three-day holiday. Temperatures would drop.
