General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 21-10-25 12h
The oceanic flow, still relatively mild but unstable over our regions, will temporarily stabilise on Wednesday before the arrival of a deepening low-pressure system estimated at 992 hPa by midday, forming west of Brittany.
This depression will intensify rapidly as it moves towards the English Channel and the southern North Sea, reaching a minimum pressure of 969 hPa by Thursday midday.
This system will bring a severe southwesterly to northwesterly storm over the Channel and southern North Sea, with gusts of 85–115 km/h inland and up to 125 km/h along the coast.
Heavy rainfall (30–60 L/m²) will accompany this depression. As its centre moves towards Scandinavia on Friday and through the weekend (975–980 hPa), it will draw in increasingly cold and unstable polar air, bringing frequent showers, mainly across the north and east of the country.
Further active rain systems are expected early next week.

Weather Evolution Summary
based on the BMCB Multimodel (ICOND2 – AROMEHD – ALADIN – ICON – AIFS – ECMWF)
Stormy winds expected on Thursday!
🌡️ Noticeable temperature drop by the weekend...
The still relatively mild oceanic air will temporarily stabilise on Wednesday before the arrival of an active low-pressure system west of Brittany.
The weather will remain mostly dry, except for a few light morning showers, especially over Flanders. The mostly cloudy sky will become more variable in the afternoon with some sunny intervals.
Maximum temperatures will range from 10–12°C in the Ardennes to 13–16°C elsewhere.
During the evening and following night, cloud cover will increase from the French border, with rain developing after midnight and a strengthening south to southwesterly wind gusting 45–65 km/h.
🌪️ Thursday: storm over Belgium
The depression will deepen rapidly towards the English Channel and the southern North Sea. The southwesterly wind will strengthen through the morning, reaching 75–95 km/h around midday across the country.
Frequent and locally heavy or thundery showers are expected.
During the afternoon, the strongest gusts will occur — first from the southwest, later turning west to northwest — reaching 95–115 km/h inland and up to 125 km/h along the coast.
➡️ Wind damage is likely!
Temperatures will start around 11–16°C and drop gradually through the afternoon to 5°C in the High Fens and about 12°C in Flanders.
By evening and overnight, the westerly to northwesterly wind will gradually ease (45–65 km/h), and showers will become fewer.
🌥️ Friday: cooler and calmer
As the storm centre moves over Denmark, colder air will flow around its western flank.
Daytime highs will reach 4–7°C in the Ardennes and 8–11°C elsewhere.
The sky will remain changeable, with sunny intervals and scattered clouds, a few morning showers, then drier and brighter in the afternoon. Another round of showers is expected in the evening and overnight.
❄️ Weekend: polar air returns
The depression will linger over southern and central Scandinavia, driving cold polar air over the North Sea region.
The weather will alternate between sunny spells and showers, sometimes with hail or sleet.
The first snowflakes could appear over the Ardennes heights, where maxima will be around 2°C.
Elsewhere, afternoon temperatures will range between 5 and 9°C.
🌧️ Early next week: unsettled and cool
New Atlantic disturbances will move in from the north, bringing wet and cool weather.
Highs will generally range from 5 to 12°C, and lows between 2 and 8°C.
No real mild spell is expected in the short term.

METEOCONSULT
BENELUX:
Update 16-10-25
Weather outlook:
Period 1–9 November: seasonal, calmer weather
Current signals point to generally seasonal conditions, with alternating clouds, sunny intervals, and occasional light rain.
Temperatures will fluctuate with the passage of weather systems and changing wind directions, shifting from northwest to southwest, bringing slight mildness at times and cooler spells at others.
🇬🇧 Week 10–16 November: limited forecast reliability
At present, the models remain highly divergent.
Scenarios range from a continued wet, unsettled southwest flow to a gradual return to calmer, anticyclonic conditions.
This evolution will largely determine the temperature trends.
Overall, November could end up close to seasonal averages, without pronounced warm or cold periods.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Update 24-9-25
October: a seasonal month, but generally dry
- Temperatures: values close to the norm, under moderate high-pressure influence, without notable extremes. The prevailing north-easterly flow may bring the first frosts, sometimes earlier than usual.
- Precipitation: estimated deficit of around –10/–20 %.
- Context: dominant high-pressure regime at higher latitudes will limit disturbances. Clear nights may lead to local frost.
🍂 November: mild and relatively dry
- Temperatures: anomaly of +0.5 to +1 °C above average, pointing to a generally mild autumn. However, fog, low clouds and inversions could keep some valleys and lowlands under persistent cold.
- Precipitation: slight deficit expected (–10 %), with a possible return of a wetter oceanic flow by the end of the month.
- Context: high pressure still dominant but gradually losing influence, opening the way for a moderately unsettled regime in the west. The rainfall deficit is likely to persist.
❄️ December: mild and wetter
- Temperatures: anomaly of around +1 °C, confirming a mild start to winter.
- Precipitation: return of disturbances with a slight surplus (~ +10 %).
