General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
A 985 hPa low-pressure system positioned north of Ireland this Sunday midday is moving towards the North Sea. At the same time, another low of 1005 hPa over the central Atlantic will deepen during the next 24 hours to around 990 hPa, heading towards the English Channel and the Benelux.
The associated rain bands will sweep across our regions, followed on Monday and Tuesday by moist and unstable maritime air, bringing showers.
On Wednesday, a ridge of high pressure will briefly stabilise conditions before new disturbances arrive on Thursday, linked to a powerful storm system that has deepened to 956 hPa south of Iceland and will move towards the Norwegian Sea on Friday and Saturday (around 974 hPa).
This system will bring fairly mild Atlantic air, though still with unsettled periods and occasional rain.
Next week, additional Atlantic lows will move between Iceland and Norway, establishing a strong south-westerly flow over western and central Europe—generally only lightly disturbed but exceptionally mild for the season.

METEOCONSULT
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.
