National Thermal Indicator
(Chart)
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.

Update – 22 January 2026 | 11:00
An atmospheric system in motion
An exceptionally deep storm depression — with a central pressure of around 958 hPa — will approach the western English Channel on Friday. Acting as a powerful driver of large-scale circulation, it will propel its active frontal systems towards France, the British Isles and the Iberian Peninsula.
Our regions will remain largely on the fringe of this system, with rainfall reaching us only in a much weakened form and without any pronounced impact.
Over the weekend, this depression will gradually fill while lingering to the west of the British Isles, with pressure rising towards 986 hPa.
At the same time, another low-pressure system will move eastwards into the Mediterranean.
This configuration will cause a shift in airflow over our areas from south-easterly to easterly, allowing increasingly continental air to move in, turning distinctly cooler to fairly cold at the start of next week.
However, this wintery interlude may prove short-lived. From around midday on Tuesday, a new depression — estimated at 983 hPa — will approach Brittany. The accompanying rain bands will cross the Benelux region, followed by the arrival of milder maritime air, leading to a gradual rise in temperatures.
Looking ahead to the end of the month and early February
Further ahead, model guidance continues to suggest a broad low-pressure zone extending from the Atlantic into France. This pattern would place our regions most often under a south-easterly flow, with a possible temporary shift to easterlies, bringing cooler to fairly cold conditions once again.
A return to milder weather, associated with a south to south-easterly flow, could occur around 3 February, though this scenario still requires confirmation. In the meantime, minimum temperatures across inland areas may frequently fall to between 0 and –4 °C, a reminder that winter still retains the ability to make its presence felt.

Expected weather evolution
Analysis based on the BMCB multimodel
(operational models and ICON – AIFS – ECMWF ensembles)
A gradual transition toward more contrasted weather conditions
📅 Saturday, 24 January
In an atmosphere still mild for the time of year, the day will be calm. Bright spells will gradually become more widespread, bringing a largely pleasant day with little or no precipitation.
📅 Sunday, 25 January
Temperatures will turn slightly cooler without becoming truly cold. Sunshine will remain present, though cloud cover will increase during the afternoon, especially over the southern Ardennes. Overnight, mist and fog patches will form across inland areas.
📅 Monday, 26 January
A fairly cold day, locally marked by low cloud and stubborn fog in low-lying areas. Brighter spells will nevertheless develop during the day, particularly across the Ardennes and more generally over Wallonia.
📅 Tuesday, 27 January
A marked change in conditions. Cloud cover will thicken rapidly, bringing precipitation that may initially fall as sleet in inland areas. Winds will strengthen, with south-easterly to easterly gusts reaching 40–60 km/h.
📅 Wednesday, 28 January
Milder air will return, accompanied by showers. It will remain windy, with gusts from the south to south-east reaching 50–70 km/h.
Likely trend
📅 Thursday, 29 January
Seasonal conditions prevail. Occasional sleet or snow showers are possible in the High Ardennes, while rain dominates in the lowlands.
📅 Friday, 30 January
Precipitation becomes more frequent. The High Ardennes may experience more sustained periods of snow or sleet, while rain remains prevalent across the plains.
📅 Saturday, 31 January
A distinctly winter-flavoured pattern, with snow at higher elevations and rain or sleet elsewhere.
📅 Sunday, 1 February
A cooler atmosphere settles in. Snow remains possible over the High Ardennes, while lower elevations mainly see rain or sleet.
📅 Monday, 2 February
Conditions stay cool and unsettled, with regular precipitation: snow at altitude, rain or sleet in the lowlands.
📅 Tuesday, 3 February
Seasonal weather continues under often cloudy skies, with a similar precipitation regime.
Summary
Overall, the period is characterised by an alternation between calm intervals and more active disturbances, with a constant balance between relative mildness and winter chill. Snow will remain largely confined to higher ground, though it may temporarily reach lower levels during transitional phases.

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 15-1-26
Period from 30 January to 8 February: fairly cold conditions persisting under a changeable sky
At this range, the most credible scenario remains that of changeable and often fairly cold weather, with no clear signal for a sustained blocked pattern. While a cold spell is likely, its duration and intensity remain uncertain at this stage.
Cold conditions could linger, particularly if high-pressure systems shift northwards towards northern Europe. However, this remains a secondary scenario for now. Overall, a seasonably cool pattern is expected, occasionally accentuated by persistent cloud cover, but without notable extremes.
Temperatures: slightly below average (≈ –1.5 °C)
Precipitation: generally close to average (–10 to +10%)
Week from 9 to 15 February: ongoing uncertainty, slow warming trend emerging
For this period, the forecast signal remains fragile and of limited reliability. A gradual retreat of the anticyclonic block would favour a more mobile weather pattern, alternating between quieter intervals and renewed unsettled spells, within an environment becoming progressively milder and more humid.
The warming trend would develop gradually, in successive stages, associated with passing rain systems, without any abrupt regime change.
Temperatures: close to average (–1 to +1 °C)
Precipitation: near average, occasionally slightly below average (–15 to 0%), depending on the persistence of high-pressure influence

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.
