National Thermal Indicator
(Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 7 January 2026 | 10 AM
The national thermal index is currently on an upward trend, signalling a brief spell of milder conditions in the heart of winter. This rise is expected to reach its peak on Friday 9 January, with values close to +2. As a result, daytime temperatures will climb to between 3 and 9°C, while night-time minima will range from -2 to +4°C.
However, this mild interlude will be short-lived. Over the weekend, a sharp drop in temperatures is forecast, leading to a pronounced cold peak on Sunday, when the national thermal index is expected to fall to -6 to -7. Under these distinctly wintry conditions, minimum temperatures will drop to between -3 and -9°C across the country, while maximum temperatures will struggle to rise above +1°C, and may remain as low as -5°C in the most exposed areas.
During the following week, a gradual easing of temperatures is anticipated. The thermal index will rise again and then fluctuate between 0 and +4, reflecting an alternation between milder days, with daytime temperatures of 4 to 10°C, and cooler periods, when maximum temperatures will range from 1 to 7°C.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update – 7 January 2026 | 2 PM
An active low-pressure system, with a central pressure of 985 hPa around midday on Thursday, will approach the southwest of Wales before deepening significantly, reaching close to 976 hPa as it moves towards the southern North Sea and the northern Benelux region.
This dynamic system will trigger a highly unsettled weather episode across our regions, bringing strong winds, a temporary rise in temperatures, widespread and at times heavy rainfall, and, temporarily, the persistence of snowfall above 500 metres on Thursday.
In its wake, on Friday and especially Saturday, a cold air intrusion originating from southern Scandinavia will spread across the country. This will be accompanied by the return of numerous snow and sleet showers. In the Ardennes, snowfall could become very heavy, with an expected snow cover of 30 to 50 cm on higher ground and 15 to 30 cm in the valleys by the start of the weekend.
On Sunday, a ridge of high pressure, peaking between 1022 and 1023 hPa, will extend from Scandinavia across Germany into our regions. This pattern will promote a gradual stabilisation of the cold air mass, now firmly established over the country.
Looking ahead to next week, forecast models suggest a renewed period of pronounced low-pressure activity over the nearby Atlantic, later shifting towards the British Isles and western France. This evolution will gradually establish a southerly flow over France and the Benelux, advecting milder air, at times slightly unsettled, from Spain and the western Mediterranean basin.

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.

( charts )
Update 4 January 2026 – 5 PM
According to the latest ensemble forecasts, the second half of January, as well as the early part of the third ten-day period, is expected to remain under the influence of persistently mild and frequently unsettled conditions.
Our regions would continue to be affected by southerly to south-westerly airflows, circulating along the south-eastern flank of an extensive low-pressure system stretching from the Atlantic across the British Isles and into the North Sea. This classic ocean-driven pattern typically brings widespread cloud cover, recurrent spells of rain, and temperatures remaining above seasonal norms.
Towards the end of January, and during the first ten days of February, the scenarios nevertheless suggest a gradual shift in the weather pattern. Our areas may increasingly come under the influence of drier, less mild and potentially colder continental air masses.
Such a transition would be favoured by the expansion of a high-pressure system from Russia towards Scandinavia, whose influence could extend westwards into our regions, paving the way for more stable, yet distinctly cooler and more wintry conditions.

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.
