We're taking advantage of the calm weather these days: a significant change in the weather is possible at the end of the week.

BarcelonaWe continue to experience very calm weather, with no precipitation anywhere and temperatures that have risen further in the last few hours, especially in the northeast, where they reached 18°C today. However, the sun is still being dimmed by bands of thin, high clouds, while low clouds were present today in many coastal and pre-coastal areas, particularly in the morning. A similar situation is expected on Wednesday, with similar temperatures and a mild and pleasant midday, even with values above average for this time of year. Only in the afternoon will a weakening front arrive in the Western Pyrenees, bringing some changes to this area. Minor variations in an otherwise calm context, as we await the end of the week, which could bring a significant change in the weather, including more rain, snow in the Pyrenees, and colder temperatures.

Wednesday: calm and gentle midday

The weather will remain very calm this Wednesday, with high, thin clouds continuing to drift across the sky and soften the sun. Low clouds and morning fog will also return to inland plains and parts of the coast and pre-coastal areas, although they will be less widespread than on Tuesday. Between the afternoon and evening, the passage of a very weak front that will brush the western Pyrenees and Pre-Pyrenees will bring increased cloud cover to this area and the northern part of Poniente. But beyond a few showers, no precipitation is expected.

Temperatures will be similar to yesterday's or slightly higher, although they will drop slightly in the Lleida region. Many highs will reach 15 to 20 °C, especially along the coast and pre-coastal areas. However, highs will be lower in inland areas in the north and in the Pyrenees and Pre-Pyrenees. Very moderate cold is expected early in the morning.

Subject to change at the end of the week

Thursday will be another very calm day, with generally sunny skies and mild temperatures at midday, but the thermometers will begin to drop slightly. The first changes will arrive on Friday, with the passage of a front that will increase cloud cover, and the first scattered, light showers will fall. The instability will intensify throughout the weekend. Cold air of polar origin will move in aloft, and a low-pressure system will form over our Mediterranean region. All of this will lead to increased precipitation. Current weather maps indicate that from Sunday onwards we will see another surge, with yet another heavy snowfall in the Pyrenees and rain across much of the country. It's raining on already saturated ground, and therefore, if these forecasts are confirmed, we will have to see if any reservoirs need to release water to accommodate the new precipitation, as the inland basins are already at 86% capacity after the abundant rains during the Christmas holidays. The situation remains uncertain and we will need to confirm it. Temperatures will drop, bringing colder, more wintry weather. These values will be more typical for this time of year.
