Two days of sunshine and mild weather before a cold front of polar origin arrives
The change in weather expected midweek will cause the snow level in the Pyrenees to plummet.
BarcelonaWe've started the week with some scattered, localized showers, variable skies, and northerly winds. Since Sunday afternoon, rainfall has locally accumulated to nearly 15 liters per square meter in some areas of northern Girona and the Pyrenees. Temperatures dropped and remained relatively mild, but Tuesday and Wednesday will bring back bright sunshine and absolute calm, with a clear rise in temperatures leading to much milder middays. However, the passage of a cold front late Wednesday will open the door to an influx of cold air of polar origin, which will significantly lower temperatures from then on, especially in the Pyrenees, where snow is expected below 1,000 meters. This slight retreat towards winter is typical for this time of year. As the saying goes, "March, March, kills the old woman by the fireside, and the young woman if she can," referring to the rollercoaster of temperatures during this transitional month between winter and spring. Therefore, it seems that the second part of the week could be cooler, but beyond showers in some regions, no significant rainfall is expected.
Tuesday: sun and calm
Tuesday will be very calm, with no repeat of the showers from Sunday and Monday. Radiant sunshine will prevail everywhere, with the exception of a few wisps of high, thin clouds, as well as some morning fog or low clouds. In the afternoon, some localized cloud cover may develop in the northeast interior and the eastern Pyrenees, but these will be completely harmless. It will be a pleasant day throughout, accompanied by a rise in maximum temperatures. There will be a marked temperature contrast between the morning chill and the mild midday weather. Most temperatures will range between 16°C and 21°C during the middle of the day.
New weather change midweek
Wednesday will be calm across most regions. Sunshine will prevail and temperatures will rise even further. A warm midday is expected, with many highs between 17°C and 23°C, locally higher in the Ebro, Priorat, and Poniente areas. However, a cold front will approach, bringing showers back to the northern slopes of the Pyrenees from the afternoon or evening onwards. The snow level will start at 1,600 meters, but will drop sharply by nightfall. This will be the prelude to an influx of cold air of polar origin that will cause a significant drop in temperatures across the board on Thursday, leading to a second half of the week with relatively mild temperatures. Snow is expected in the Pyrenees, especially on the northern slopes, with the snow level potentially falling as low as 800 meters. On Thursday, scattered showers are also expected in areas of Barcelona and Girona, with strong mistral and tramontana winds in the outer regions.
In short, in the coming days we will have 100% spring-like weather, with a bit of everything and a rollercoaster of temperatures, although in the medium term no general or significant episode of rain is expected.
