General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 22-11-25 11h
An oceanic low-pressure system, deepening to 986–987 hPa, will reach the northern British Isles around midday on Sunday before moving into the North Sea. The associated rainbands will sweep across the Benelux region on Sunday, followed on Monday by unstable and seasonably cool air.
As this depression, near 998 hPa, extends from Central Europe towards northern Italy, our region will remain under a fresh and unstable northerly flow. A gradual stabilisation of the air mass is expected by mid-next week.
From Thursday onward, the circulation will shift to a southwesterly flow, bringing new rainy disturbances. Milder air will then move in progressively, lasting at least through the weekend and into the start of the following week.

(These forecasts are generally updated daily)
Update: 22-11-25, 12h
The national thermal index is set to rise gradually, fluctuating between –3 and 0°C from 23 to 27 November.
Daytime temperatures will initially range from –2 to +6°C, then increase to 4 to 11°C, with some nighttime frost still possible, especially south of the Sambre–Meuse axis from 25 to 27 November.
After 27 November, daytime highs will generally vary between 5 and 11°C on the cooler days and 8 to 14°C on the milder ones.
Night frost will fade progressively across the Ardennes.

BENELUX:
Weather Outlook for 3-4 weeks
Update 21-11-25
Period 6–14 December: pronounced mildness, frequent fog, and very calm conditions
For the second third of December, signals remain clearly mild across Western Europe. The Atlantic disturbance flow should mainly affect the Mediterranean and northern Maghreb.
Across the Benelux and France, a dry, high-pressure-dominated pattern prevails, with a high-pressure core positioned over Germany.
No organised winter outbreak is expected: temperatures will stay well above average, with mild but fog-prone mornings, followed by pleasant and brighter afternoons once the fog lifts.
Week 15–21 December: calm and dry weather with falling temperatures
A powerful Scandinavian high may take control, bringing continental influence across much of the region.
Within this north-easterly flow, temperatures may drop from Germany, with the intensity and dryness of the cooling depending on the strength of the continental air mass.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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.
