General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 12-11-25 10h
Very mild southerly air continues to move northwards across France, the Alps, and Germany, while on Thursday, a weak band of rain will affect the northwestern half of Belgium and the Netherlands.
On Friday, this disturbance will shift northward as a warm front, becoming more active over England and the Netherlands, while a cold front advances eastward across France.
This front will reach our regions on Saturday, though much weakened.
During the weekend, an Atlantic depression (990–997 hPa) linked to these systems will move to the west of the Bay of Biscay, then toward the Pyrenees.
This will temporarily bring a cooler, continental air flow, dry and relatively stable.
At the same time, a cool polar air stream will establish itself over the North Sea, and early next week, it will begin to influence our weather, bringing increasing instability and a few showers.

Weather Outlook for 3-4 weeks
Update 7-11-25
Weather Outlook: Milder and Drier Toward the End of November
Period: November 22–30 – Turning Drier but Still Mild
Current model guidance suggests cloudy but mild conditions continuing across most areas, with temperatures above seasonal averages.
Later in the period, a high-pressure ridge developing to the south could bring drier weather across the region.
Week of December 1–7 – Cooling Trend Ahead?
Forecast confidence remains low for early December.
Some scenarios maintain mild and mostly dry conditions, while others hint at colder air moving in later in the week.
➡️ Further updates will refine this outlook.

Weather Outlook for 3 months
Update 11-11-25
Winter Outlook 2025–2026: mostly mild with variable conditions
🌡 Temperatures: around or slightly above normal (+0.5 °C), with a wide spread among models, meaning no dominant scenario can be confirmed.
🌧 Precipitation: near seasonal averages, with a possible surplus in eastern and mountainous areas.
🌬 General context: alternating between calm, high-pressure periods and unsettled spells, with no lasting cold outbreaks.
🔹 Summary December 2025 – February 2026:
Winter is expected to be slightly milder than average, with a mean thermal anomaly of +0.5 to +1.0 °C.
Rainfall totals should remain close to normal — slightly below average in December, above in January, balancing over the season.
A dominant westerly oceanic flow and frequent anticyclonic influence will limit major cold waves.
Under La Niña influence, circulation contrasts could intensify — bringing mild and wet conditions to western Europe, with brief but sharper cold spells in February.
