MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 22 January 2026 | 9 a.m.
A distinctly colder phase is emerging on the horizon.
Temperatures will decline over the coming days, with the national thermal index expected to reach –3 to –4 by Monday, 26 January.
In this context, daytime maxima will range between –3 and +3°C, while night-time minima will fall between +2 and –4°C, reflecting a clearly cool to fairly cold regime, conducive to the development of frost.
However, this episode is not expected to persist.
In the days that follow, the thermal index will gradually recover towards near-neutral values, alternating with slightly milder phases ranging from +1 to +3. During the cooler spells, maximum temperatures will remain limited to 0–6°C, while milder periods may see the mercury rise to 4–10°C, depending on elevation.
In summary, the end of the month is set to be shaped by a succession of cool to fairly cold pulses interspersed with temporary milder intervals, resulting in a fluctuating winter pattern, free of prolonged extremes but marked by pronounced thermal contrasts.

General Weather Evolution for the Next Days

Update – 23 January 2026 | 11 a.m.
An atmospheric mechanism in full transition
The atmospheric circulation is entering a clearly defined transitional phase. On Saturday, a broad low-pressure system, with central pressures ranging from 974 to 994 hPa, will stretch from the southwest of the British Isles down to southern France. By Sunday, this structure will extend from Brittany towards the northern Adriatic, triggering a gradual shift in airflow over our regions — initially from the southeast, then turning easterly.
This change in circulation will pave the way for the arrival of continental air, which will establish itself from Sunday onwards. Gradually cooling, this air mass could become markedly cold by early next week, significantly altering the overall weather pattern.
On Tuesday, a new depression, estimated at around 972 hPa, will move into the entrance of the English Channel. Its associated rain bands will affect our regions during the course of the day. By Wednesday, these fronts will move eastwards, briefly allowing milder oceanic air to return.
However, this respite will be short-lived. On Thursday, a new and deep low-pressure system is expected to approach, with its core potentially dropping to around 962 hPa over the Channel. This system will bring another unsettled episode, with locally heavy precipitation.
Looking towards the end of the month and early February
The end of January is likely to remain dominated by the near-permanent presence of an active low-pressure zone over the nearby Atlantic and the English Channel. Under the influence of a frequently unstable or disturbed southerly flow, conditions will remain often wet, with temperatures generally on the mild side for the season.
Between 1 and 6 February, little change is expected in this overall pattern. Wet and unsettled conditions are likely to persist, with temperatures close to seasonal averages. Towards the end of the period, a more noticeable cooling trend could emerge, signalling the onset of another shift in the atmospheric regime.

Weather evolution according to the BMCB multimodel
(Operational models and ensembles ICON – AIFS – ECMWF)
Late January is set to unfold under a highly changeable weather pattern, alternating between wintery coolness, unsettled spells and milder phases, with a marked contrast between the lowlands and the Ardennes uplands.
Sunday 25 January
Seasonal conditions will prevail, with a mix of cloud and occasional brighter spells. During the night, a few light showers and some sleet above 500 metres may occur, followed by clearer intervals and the formation of local fog patches.
Monday 26 January
A rather cold atmosphere will dominate, with increasingly widespread sunny intervals. Overnight, cloud will gradually increase again, bringing some light rain to the western half of the country.
Tuesday 27 January
The disturbance becomes more pronounced: skies turn overcast, rainfall may at times be persistent, and windy conditions develop. South-easterly gusts could reach 60 to 80 km/h. During the night, broad clear spells will move in from the west.
Wednesday 28 January
Milder air will take hold under a variable sky with sunny intervals. Southerly winds remain noticeable, with gusts of 50 to 70 km/h.
Thursday 29 January
Further rain will spread in from the west, in an atmosphere that stays mild and fairly windy under a southerly flow.
Likely trend
The following period will remain under a persistently unsettled regime, with a succession of frontal systems and a continued contrast between lowland areas and higher terrain.
From Friday 30 January to Friday 6 February
Conditions will be broadly seasonal to occasionally mild in the lowlands, while the High Ardennes retain a distinctly more wintry character, with recurring episodes of snow or sleet. Precipitation will be frequent and at times significant, falling mainly as rain at lower elevations.
Overall, the transition from January into February looks set to be unstable, wet and highly contrasted, with winter firmly established over higher ground and a more oceanic influence prevailing in the lowlands.

Outlook anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Update – 23 January 2026
Around the transition from the first to the second ten-day period of February, the atmospheric pattern is expected to remain dominated by a broad low-pressure system, with its disturbed axis stretching from the Atlantic across northern France into Central Europe. Our regions would lie along its northern flank, temporarily exposed to a continental north-easterly to easterly flow, bringing cooler air and a more distinctly wintry character.
Towards the end of the second ten-day period and during the third, a gradual change in the weather regime is likely to emerge. The retreat of the low-pressure system towards the nearby Atlantic, combined with the strengthening of a large anticyclonic area over the central and eastern Mediterranean and Eastern Europe, would promote the northward advection of significantly milder but still fairly unsettled air from France into our areas.
This milder trend is expected to persist into early March. Reduced low-pressure activity over the Atlantic and the continued dominance of high pressure across the Mediterranean would then favour a more stable atmospheric setup, characterised by milder temperatures and a noticeably less wintry and less humid feel.

Weather Outlook for 3-4 weeks
Update 23-1-26
Period from 7 to 15 February: a possible return to seasonal conditions
As the Atlantic storm track gradually slows, weather conditions may begin to settle. Fewer disturbances would affect the region, allowing for more frequent and sometimes prolonged sunny intervals.
A strengthening influence of high pressure over northeastern Europe would favour more stable and drier conditions, with temperatures returning closer to seasonal norms. A calm, seasonably cool winter pattern may take hold.
Week from 16 to 22 February: a more wintry atmosphere returning?
These longer-range signals should be interpreted with caution, yet they hint at a potential re-establishment of more distinctly wintry conditions. Dry cold air could once again dominate, often accompanied by typical low-level phenomena such as persistent fog, extensive low cloud cover and pronounced temperature inversions.
A subdued but tangible winter atmosphere could then settle across the region.

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.
