General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 19-11-25 11h
A low-pressure system, fluctuating between 999 and 1006 hPa, will stretch this Thursday from the southern Baltic Sea across the North Sea and down to the northern Adriatic. Along its western flank, it will direct a rather cold and unstable polar air mass towards our regions.
On Friday and Saturday, a high-pressure ridge will move from west to east over Western Europe. It will stabilise the cold air, resulting in mostly clear skies and consequently cold nights and chilly mornings.
This weekend, a new Atlantic depression (993–983 hPa) will reach the northern British Isles. Its associated front will move across the Benelux, bringing rain or snow depending on the region.
Early next week, this system will be followed by an unstable or disturbed oceanic flow, less cold yet still cool for the season. Low-pressure centres between 982 and 997 hPa near our area will generate wet snow or snow over the Ardennes highlands, but mainly rain in the lowlands.

National Thermal Indicator (Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update: 19-11-25, 12h
The national thermal indicator, after a brief pause in its decline, will drop again in the coming days. It is expected to reach its minimum of around –7 on 22 November, with minimum temperatures generally between –2 and –8 °C, and even colder in the Ardennes valleys (–9 to –13 °C). Maximum temperatures will range between –1 and +5 °C.
Afterwards, the indicator will gradually rise again, turning positive around 29 November. Early December should bring values between +1 and +4, corresponding to daytime temperatures of 5 to 12 °C.

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.
