National Thermal Indicator
(Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 9 January 2026 | 10 AM
A sharp winter plunge is expected over the next 48 hours, with the national thermal index dropping rapidly to a notably low minimum around –5, signalling a marked cold outbreak across the country.
Daytime temperatures will struggle to rise above –3 to +3°C, while night-time minima will generally range between –3 and –9°C.
Conditions will be considerably harsher in the valleys south of the Sambre–Meuse line, where during the night from Saturday to Sunday, temperatures may fall to –10 to –15°C, and very locally even to –16 to –19°C — exceptionally low values.
This icy interlude will be followed by an equally striking rebound in temperatures. During the first half of next week, the national thermal index is expected to climb rapidly to +5 to +6, bringing daytime temperatures of 6 to 12°C and a return to much milder, Atlantic-influenced conditions.
For the remainder of the week and into the following week, the index is likely to fluctuate between +1 and +4, resulting in maximum temperatures generally ranging from 3 to 11°C, within a more temperate and less contrasting weather pattern.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update – 9 January 2026 | 12 PM
The 977 hPa low-pressure system currently moving eastward across the Benelux will be followed by a gradual influx of colder air. This cooler air mass will remain slightly unstable on Saturday, bringing a mix of cloud, brief clear spells, and locally changeable conditions.
By Sunday, the weather pattern will shift noticeably. The cold air will become fully stabilised and drier as a strong 1027 hPa anticyclone establishes itself over Germany, leading to calmer and more settled conditions.
On Monday, this high-pressure system will drift towards southeastern Europe, temporarily allowing a rain-and-snow disturbance to cross our regions. This system will quickly clear, making way for a markedly milder and more humid air mass advancing from the south-west of France.
As next week progresses, low-pressure activity will remain focused over the near Atlantic and the British Isles. Consequently, our weather will be governed by a southerly to south-westerly flow, occasionally unsettled but persistently mild to very mild for the time of year.

Summary of the expected weather evolution
based on the BMCB multimodel
(operational models and ensembles ICON – AIFS – ECMWF)
📅 Friday, 9 January
Rainfall (24 h): 20–55 l/m²
Temperatures: minima -2 to +4 °C | maxima 3 to 9 °C
A highly unsettled and wintry day lies ahead. Conditions will be cool and windy, with strong gusts of 70 to 90 km/h from the west to northwest.
Skies remain fully overcast, bringing heavy showers of rain or graupel. Marked falls of graupel or wet snow are expected across the Campine region and south of the Sambre–Meuse line, while snow becomes widespread above 300–400 metres.
Overnight, the atmosphere remains unstable, with further sometimes heavy showers of sleet or snow across all regions.
📅 Saturday, 10 January
Rainfall (24 h): 4–30 l/m²
Temperatures: minima -6 to 0 °C | maxima -3 to +3 °C
The cold air tightens its grip. Snowfall will gradually ease over western and central areas, but light snow showers may persist around Liège and east of the Meuse.
During the night, conditions turn increasingly dry, with wide clear spells and moderate to locally severe frost, particularly across the eastern half of the country.
📅 Sunday, 11 January
Rainfall (24 h): 0–2 l/m²
Temperatures: minima -9 to -3 °C, locally -10 to -18 °C south of the Sambre–Meuse line | maxima -5 to +1 °C
A very cold day, still fairly windy with gusts of 50–70 km/h from the south to southeast.
The morning will be bright and sunny, before cloud increases later in the day from the southwest.
Overnight, a new precipitation system arrives, with snow turning to rain, while snow persists across the Campine and the Ardennes.
📅 Monday, 12 January
A cool and gloomy day, dominated by persistent rain.
📅 Tuesday, 13 January
A shift towards notably mild conditions for the season, accompanied by rainy weather.
🔎 Likely outlook
From 14 to 21 January, weather conditions are expected to be largely seasonal, often dry or with only light precipitation, locally sleet or snow over the Ardennes.
Around Wednesday, 21 January, a renewed period of more widespread and moderate precipitation is likely, with milder air returning.

Forecast anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Update – 10 January 2026
The latest analyses based on ECMWF ensemble guidance, focusing on mid-tropospheric anomaly patterns, outline a markedly contrasted synoptic setup across Europe towards the end of January.
A broad anticyclonic system is expected to establish itself over northern Europe, while a low-pressure zone extends across the Mediterranean Basin and the Maghreb.
Between these two dominant systems, a colder continental airflow from the north-east to east is likely to take hold across our regions, reinforcing a distinctly wintry atmosphere.
Looking ahead to the second ten-day period of February, the anticyclone is forecast to shift southwards, stretching from northern France towards central Europe. This evolution would favour a calm, dry and stable weather regime, with markedly reduced frontal activity.

Weather Outlook for 3-4 weeks
Update 31-12-25
Weather Trends – Mid to Late January
15 to 25 January: mild and unsettled conditions
This period is expected to be influenced by a west to south-westerly airflow, remaining fairly unsettled. Between 19 and 25 January, a succession of Atlantic low-pressure systems could affect the region, bringing recurrent spells of rain, interspersed with temporary quieter intervals.
Within this pattern, temperatures are likely to rise slightly above seasonal averages, though without any pronounced anomalies. Overall, this would result in a generally mild and humid winter regime, driven by Atlantic influences.
26 January to 1 February: potentially calmer and more seasonal
At this range, forecast confidence remains low, and these trends should therefore be interpreted with caution.
Based on the current ensemble mean of the models, a gradual easing of conditions cannot be ruled out. Weather patterns could then move closer to seasonal norms, with temperatures near average and a changeable sky, but without any significant disturbances.
Such a configuration would be conducive to the formation of fog and low cloud, particularly across low-lying areas and valleys, due to stable conditions in the lower atmospheric layers.

Weather Outlook for 3 months
Update 13-12-25 – 3:00 PM
January 2026: a wintry spell before milder conditions return
January 2026 is expected to open with a distinctly wintry phase, followed by a clear and lasting return to milder conditions during the second half of the month.
The nationwide temperature anomaly is estimated at +0.7°C, pointing to an overall mild month despite a cold start.
Early January could bring low temperatures and a risk of snowfall reaching lowland areas.
From mid-January onwards, Atlantic influences are likely to dominate, bringing temperatures well above seasonal averages.
In terms of precipitation, a slight surplus (+5%) is anticipated. Weather systems would be fairly frequent at the beginning of the month under a northerly flow, before shifting to a westerly to south-westerly Atlantic regime from mid-month.
As a result, January could become the wettest month of the 2025-2026 winter.
February 2026: slightly drier and still mild
February is expected to remain generally mild, with a temperature surplus close to +1°C.
Weather conditions are likely to be contrasting, with cold mornings followed by milder and often sunny afternoons, as high-pressure systems settle more frequently over the region.
Precipitation totals would be slightly below average (-10%), with less active weather systems due to the influence of persistent high pressure over continental Europe.
March 2026: finally a seasonal month?
March could finally deliver near-average seasonal conditions.
Temperatures are expected to fluctuate around climatological norms, with alternating cooler periods and milder, more unsettled phases, typical of early spring.
Precipitation should be close to average overall, though locally below normal, under the possible influence of high-pressure systems over northern Europe.
