General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update 21-11-25 11h
The anticyclonic ridge, fluctuating between 1026 and 1028 hPa, continues to provide stable, dry yet cold conditions across our regions. As it gradually shifts eastward, it will open the door to a rain-bearing disturbance expected to reach England and Brittany on Saturday.
This initial system will soon be joined by a second disturbance, driven by a 987 hPa depression expected over northern England on Sunday midday. It will then slide towards the Benelux countries and the southern North Sea (≈989 hPa), bringing areas of precipitation in an air mass that becomes slightly less cold, though still cool for the season.
By Tuesday, as this depression (≈1000 hPa) stretches from northern Italy to Hungary, our country will remain under an unstable and cool northerly flow from the North Sea. This pattern will persist until Wednesday, when a new anticyclonic ridge arrives, paving the way for a strengthening high-pressure system of 1029 hPa over central Europe on Thursday.
Towards the end of the week and into the following weekend, a south-westerly flow is likely to set in, alternating between mild and cooler phases, accompanied by passing frontal systems linked to oceanic depressions.

National Thermal Indicator (Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update: 21-11-25, 12h
The national thermal indicator will remain variable until 27 November, fluctuating between 0 and –6°C. Daytime temperatures will range from –1 to +6°C on the coldest days and from +1 to +8°C on moderately cold days.
Over the next 24 hours, night-time and early-morning frost will be frequent, with minimum values generally between –6 and 0°C, and locally even lower (–7 to –12°C) in the valleys of the eastern regions.
After 27 November, a gradual warming trend is expected: the thermal indicator should rise to 0 to +4°C, with daytime highs increasing from 3–10°C to 6–13°C, and night- and morning frost progressively fading.

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 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.
