National Thermal Indicator
(Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – Tuesday 28 January 2026 | 9:00
Belgium’s national thermal index is expected to decline markedly over the next 48 hours, falling towards a value close to –1. This downturn will be reflected in daytime temperatures generally ranging between 1 and 8°C, while night-time minima are forecast to vary between –3 and +4°C, signalling a noticeably cooler spell across the country.
Thereafter, the thermal index is projected to fluctuate upwards again, settling within a range of +1 to +5. In practical terms, this would translate into maximum temperatures of 7 to 13°C on the mildest days, and 4 to 10°C during less favourable periods.
From 6 February onwards, a renewed cooling trend is anticipated. The thermal index could slip back to values between 0 and –2. Daytime temperatures would initially range from 2 to 8°C, before gradually easing down to 0 to 6°C, while night-time temperatures may fall to between –4 and +3°C.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps
UPDATE – Wednesday 28 January 2026 | 11am
Relatively cool and humid air will continue to linger over the country this Thursday, ahead of the approach of an Atlantic depression estimated at around 981 hPa, expected to reach south-west England on Friday. The associated rain bands will move into our regions later on Friday. They will be accompanied by a marked advection of very mild air, heralding a noticeably more settled and milder weekend across the entire country.
At the start of next week, another depression (with central pressure between 984 and 985 hPa) will move northwards close to the western European coasts. This pattern will keep our regions under the influence of a mild southerly flow for much of the week, generally with limited disturbance.
Only towards the end of next week and during the following weekend could a change in regime occur. A further, more vigorous Atlantic depression (971 to 980 hPa) will move from the Portuguese coast towards the Bay of Biscay and then south-west France. This could promote the establishment of a continental flow gradually veering east to north-east, bringing cooler air back over the country.

Outlook anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Update – 28 Jan 26 | 4 pm
A cooler spell becomes possible around February 10th, but not before, according to the GEFS and ECMWF ensembles.
Until then, conditions are expected to remain occasionally unsettled, but generally mild to very mild.
For the first half of February, two scenarios are emerging:
- a chaotic wintry setup (rain, snow and thawing phases),
- or a well-structured and more pronounced winter spell.
The strengthening of the Greenland high, now supported by GEFS, adds credibility to the colder scenario, although caution remains warranted.
In any case, this would represent the last winter opportunity before mid-month, short-lived, followed by a return to near-average conditions around the 20th, and then drier and markedly milder weather heading into March.

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.
