General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 15-11-25 11h
A 994 hPa depression, centred this Saturday midday west of the Bay of Biscay, will continue to fill and expand on Sunday, stretching from the Bay of Biscay toward northeast France and Poland (1004 hPa).
This evolution will place our region under a north to northeast flow, bringing progressively cooler air, while a frontal system moves across the country from north to south.
On Monday, this disturbance will be replaced by a cooler, unstable polar flow from the north to northwest, producing a few showers, with sleet possible over the higher ground of the Ardennes.
On Tuesday, a new low will develop over Scotland (1003 hPa) and move Wednesday and Thursday toward the eastern North Sea (994 hPa) and the southern Baltic (1000 hPa).
The associated front will reach our regions on Wednesday, bringing rain in lowlands, sleet above 300 m, and snow from 500–600 m.
Behind the system, cool and unstable polar air will generate further showers on Thursday — rain or graupel in the plains, sleet or snow over the Ardennes — until a mobile high-pressure ridge brings more stable weather overnight, along with widespread frost under clear skies in the eastern half of the country.

(These forecasts are generally updated daily)
Update: 15-11-25, 12h
The national thermal index will continue to drop over the coming days, turning negative from Monday, November 17.
The lowest point is expected around November 22, with values between –3 and –4, corresponding to daytime temperatures of 0 to +6°C across Belgium.
Minimum temperatures will range roughly from +4°C in the west to –2°C in the east, where frost will be more likely.
A confirmed warming trend is expected afterwards, with the thermal index likely turning positive again after November 26.

Based on the BMCB multimodel (ICON – AIFS – ECMWF, operational + ensembles)
Monday
Frequent showers from the morning across most regions except the south of Luxembourg province. Above 500–600 m, some sleet or ice pellets are expected. Brighter spells will develop during the afternoon.

BENELUX:
Weather Outlook for 3-4 weeks
Update 13-11-25
Period from November 28 to December 7: calmer and fairly mild trend
Forecast confidence for early December remains very low, as weather models are still highly divergent.
The prevailing trend points toward a strengthening anticyclonic ridge between the Atlantic and Central Europe, bringing calmer conditions.
Expect widespread grey skies, fog, and low clouds, with temperatures slightly above normal for the season.
Week of December 8–14: relative mildness, fog, and calm weather?
For the second week of December, the overall signal remains mild across Western Europe.
A disturbed westerly flow will mostly affect the British Isles and the northern parts of the continent, leaving Belgium under calmer, sometimes damp conditions, with no structured winter cold spells.
- Temperatures: slightly above average.
- Precipitation: near normal, locally a bit higher.
A possible early stratospheric warming over the Arctic could alter the large-scale circulation later in the month, keeping confidence levels low.

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.
