General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update: 27-11-25 – 12 PM
A deep low-pressure system of 956–964 hPa will move northeast over the next 24 hours between Iceland and Scotland, pulling a milder southwesterly flow across our regions.
A weak warm front will cross the country this Thursday, followed by a cold front tomorrow, Friday, moving through the mild oceanic air.
At the start of the weekend, a secondary low (around 1001 hPa) is expected over England. It will shift toward the eastern North Sea while deepening slightly (~995 hPa). It will maintain rainy weather over Belgium and bring a brief influx of cooler air late in the weekend and early next week.
Meanwhile, additional rain-bearing disturbances combined with mild air will reach the British Isles and western France, impacting our weather again on Tuesday and Wednesday.

National Thermal Indicator (Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update 27 November 2025 – 1 PM
The national thermal index, currently still around –2, is expected to rise gradually over the coming days. It will most often fluctuate between +1 and +4, except on 1 December, when it may briefly drop back to around 0.
These values correspond to daytime temperatures of:
- 4 to 10°C during the cooler days,
- 6 to 12°C during the milder periods.
A risk of light, localized overnight frost remains, especially south of the Sambre–Meuse axis, during the night of 30 November to 1 December.

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 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.
