The weather will change again starting today and throughout the weekend
In the coming days, showers will return to many places and snow to the Pyrenees, with increasingly cold weather.
BarcelonaYesterday was the calmest day of the week, with sunshine everywhere, fog, and clear skies at midday. For the first time this week, it didn't rain anywhere, after the downpours and showers of the previous days. But this calm is short-lived, as changes are expected starting today, with the return of some showers in the northeast. On Saturday, rain will spread to more areas, and temperatures will begin to drop. Locally heavy rain is possible in the Girona and Barcelona regions, so Civil Protection has activated the Inuncat flood plan. The arrival of a pocket of cold air and new storms will mean that the coming days—including Christmas week—will be marked by rain, snow, and the cold of midwinter.
Friday: first changes
Friday morning will still be very calm and sunny in many areas, although there will be morning fog and low clouds. Cloud cover will increase along the Costa Brava, bringing the first showers or light rain. During the afternoon, an approaching front will bring increased cloud cover, with overcast skies towards the northeast, where scattered showers will reappear. The snow level will be around 2,000 meters, and temperatures will be similar or slightly lower, especially the minimums, with a chilly morning and many maximums between 12 and 17 degrees Celsius.
It is possible that some of these showers could be locally intense. Therefore, the Meteorological Service of Catalonia (SMC) has issued alerts for heavy rainfall exceeding 20 l/m² in just half an hour in several districts of Girona and Barcelona, both today and on Saturday.
Busy and colder weekend
The approach of a pocket of cold air and the passage of a new front will bring more unsettled weather this weekend. While some uncertainty remains, Saturday will be generally overcast, with rain expected in the Girona and Barcelona regions, as well as in the Pre-Pyrenees. Showers are possible in other areas. Snowfall will intensify in the Eastern Pyrenees, with the snow level dropping to 1,800 meters. Temperatures will be lower.
Sunday will be colder, with generally variable skies. A more wintry atmosphere will coincide with the official arrival of the new season. Throughout the day, an approaching low-pressure system will bring moderate westerly winds and precipitation to the Pyrenees and the western Pre-Pyrenees, especially in the afternoon. The snow level may drop below 1,500 meters.
With even more uncertainty, low-pressure systems will circulate across our latitudes throughout Christmas week, as the anticyclone settles over central and northern Europe, causing instability to persist in our region. We can expect unsettled days, with a risk of further precipitation and snowfall in the Pyrenees. Temperatures will drop even further, creating a cold and wintry atmosphere, with values below average. We will have the coldest Christmas in recent years.
Depending on the final position of the low-pressure system and the cold air mass, we will have more or less precipitation, with the snow level potentially dropping below 1,000 meters. All of this will need to be monitored very closely and confirmed.
