General Weather Evolution for the Next 6 Days

Europe: Analysis & Forecast maps (6 days)

Update 2-10-25 at 12 AM – Evolution of the Weather Pattern

Atmospheric evolution

A storm depression, originating from the remnants of Hurricane Humberto, is currently deepening in the middle of the ocean.

On Friday, it will move east-northeast towards Scotland, with a central pressure estimated between 961–967 hPa.

The associated active rainbands will sweep across the Benelux mainly during the night from Friday to Saturday.

By Saturday afternoon, the depression — deepened to around 949 hPa — will track northeastwards towards the Shetlands and the Norwegian Sea. It will establish a strong oceanic westerly to northwesterly flow across Western Europe, bringing fairly cool but overall only slightly unstable air over our country.

At the start of next week, a strong anticyclone (1029–1030 hPa) will shift from the nearby Atlantic towards central France and southern Germany.

This will lead to a gradual stabilisation of the oceanic air mass, which will also turn milder from Tuesday onwards, fed from the Bay of Biscay and southwestern France.

By midweek, a weak cold front is expected to cross our regions, setting up a more unstable and unsettled westerly oceanic regime across much of Western Europe, with temperatures close to seasonal norms.

METEOCONSULT

BENELUX:

Update 2-10-25

Weather outlook:

October 17–26: return of disturbances

The end of October is expected to remain relatively unchanged. Atlantic disturbances could once again approach our regions, bringing wetter and occasionally unsettled conditions.

Week of October 27–November 2: seasonal weather

As we head into Halloween and the start of November, no clear scenario emerges. The weather may stay rather mixed, with humidity and occasional showers, in line with the season.
Regarding temperatures, the outlook remains uncertain, though overall mildness may have the upper hand.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Update 24-9-25

October: a seasonal month, but generally dry

Temperatures: values close to the norm, under moderate high-pressure influence, without notable extremes. The prevailing north-easterly flow may bring the first frosts, sometimes earlier than usual.
Precipitation: estimated deficit of around –10/–20 %.
Context: dominant high-pressure regime at higher latitudes will limit disturbances. Clear nights may lead to local frost.

🍂 November: mild and relatively dry

Temperatures: anomaly of +0.5 to +1 °C above average, pointing to a generally mild autumn. However, fog, low clouds and inversions could keep some valleys and lowlands under persistent cold.
Precipitation: slight deficit expected (–10 %), with a possible return of a wetter oceanic flow by the end of the month.
Context: high pressure still dominant but gradually losing influence, opening the way for a moderately unsettled regime in the west. The rainfall deficit is likely to persist.

❄️ December: mild and wetter
