General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update – 24/11/2025, 11:00
A 990 hPa depression currently driving the humid, unstable yet slightly milder weather is centred over the North Sea at midday. On Tuesday it will move toward northern Italy and Croatia (≈ 999 hPa).
Until then, it maintains a fresh and unstable northerly flow over the country. On Wednesday, a stabilising ridge will extend over France, the Benelux and Germany.
On Thursday, a deep low of around 956 hPa will develop south of Iceland, bringing an increasingly mild southerly airflow by the end of the week along with rain-bearing disturbances.
Early in the weekend, a secondary 994 hPa low will affect southern England before moving on Sunday towards the Netherlands, weakening to around 1004 hPa. It will still produce rain or showers in a cooler maritime air mass.
Next week, further Atlantic depressions west of Europe will re-establish a mild to very mild southerly flow across western Europe with frequent rainy spells.

National Thermal Indicator (Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update: 24/11/2025 – 10 a.m.
The thermal indicator will remain negative until 27 November, fluctuating between 0 and –2°, with daytime highs between 2 and 9°. After that, it turns positive and varies between 0 and +5°. Across Belgium, this means daytime temperatures of 4 to 11° on the cooler days and 6 to 13° on the milder ones.

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 26-11-25
December 2025: a rather mild start to winter, no clear precipitation signal
Temperatures: positive anomaly of +0.5°C to +1.0°C. Few lasting cold spells; alternating polar incursions and milder phases, similar to November. High confidence in above-average temperatures.
Precipitation: near normal, locally slightly below average in the north and east. Low confidence.
General pattern: prevailing west–southwest flow, alternating unsettled periods and calmer phases. Limited lowland snow, but regular snowfall at higher elevations.
January 2026: more contrast, unsettled and generally mild
Temperatures: continued thermal surplus (+0.5°C to +1.0°C). Some short-lived wintry episodes possible due to continental cooling. Probability of mild conditions dominating: > 60%.
Precipitation: slight excess (+5% to +20%) in western, southern and upland areas; elsewhere near normal. Medium confidence.
General pattern: renewed active Atlantic flow with successive disturbances, risk of windstorms and notable snowfall in mid-mountains. In lowlands, snow remains scarce and brief.
February 2026: more variable, closer to seasonal norms
Temperatures: near normal to slightly above (0 to +0.5°C), with large scenario spread and potential for brief cold spells. Low confidence.
Precipitation: around normal, possibly slightly wetter in the east and uplands. Low confidence.
General pattern: alternating high-pressure phases and unsettled returns. Colder outbreaks linked to a weakened polar vortex remain possible, particularly late in the month.
Winter 2025–2026: summary
A slightly milder-than-average winter with a mean anomaly of +0.5°C to +1.0°C. Precipitation near seasonal norms overall — drier in December, wetter in January.
Dominant scenario: frequent Atlantic influence, regular disturbances, cold spells generally short-lived. La Niña and a potentially weakened polar vortex may still promote sharper wintry episodes, especially in January, without altering the overall mild signal.
