General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update: 30/11/2025 – 12:00
Cooler air continues to move into the region, following the cold front that crossed the country during the night.
Tomorrow, Monday, new rain-bearing disturbances will reach Brittany, the English Channel and the western part of the country. They will then cross Belgium in a much weakened state, before yielding to a rather mild southerly flow. This warmer air will be brought in by a large low-pressure system of 964 to 976 hPa, moving early in the week from south of Iceland to west of Scotland.
By mid-week, additional Atlantic depressions are expected. One of them, deepened to 993 hPa, will move on Thursday from the Bay of Biscay towards the western Mediterranean. This shift will place our regions under the influence of an anticyclonic ridge of around 1018 hPa on Friday, stretching from Brittany to the Netherlands.

(These forecasts are generally updated daily)
Update – 30 November 2025, 11 a.m.
Over the next 24 hours, the national thermal index is expected to be around –1. It will then rise slightly, fluctuating between 0 and +5 during the first two weeks of December.
As a result, daytime temperatures should range from 3 to 10°C on the cooler days, and between 6 and 13°C on the milder days, with some regional variations.

Weather Outlook for 3-4 weeks
Update 28-11-25
Period 13–21 December: potential cooling
Following a brief cold spell expected between 15 and 18 December, a rather chilly week may develop, with occasional snow showers. Several aspects still require refinement: the intensity of the cooling, the lowering of the rain–snow limit, and the actual duration of this colder phase, which currently does not appear long-lasting.
Week of 22–28 December (Christmas Week)
No strong trend emerges for Christmas week. Current model guidance leans towards changeable and at times unsettled weather, with temperatures close to seasonal norms. A colder pattern cannot be ruled out if a blocking configuration were to form between Greenland and Scandinavia, but this remains a minority scenario.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Weather Outlook for 3 months
Update 26-11-25
December 2025: a rather mild start to winter, no clear precipitation signal
Temperatures: positive anomaly of +0.5°C to +1.0°C. Few lasting cold spells; alternating polar incursions and milder phases, similar to November. High confidence in above-average temperatures.
Precipitation: near normal, locally slightly below average in the north and east. Low confidence.
General pattern: prevailing west–southwest flow, alternating unsettled periods and calmer phases. Limited lowland snow, but regular snowfall at higher elevations.
January 2026: more contrast, unsettled and generally mild
Temperatures: continued thermal surplus (+0.5°C to +1.0°C). Some short-lived wintry episodes possible due to continental cooling. Probability of mild conditions dominating: > 60%.
Precipitation: slight excess (+5% to +20%) in western, southern and upland areas; elsewhere near normal. Medium confidence.
General pattern: renewed active Atlantic flow with successive disturbances, risk of windstorms and notable snowfall in mid-mountains. In lowlands, snow remains scarce and brief.
February 2026: more variable, closer to seasonal norms
Temperatures: near normal to slightly above (0 to +0.5°C), with large scenario spread and potential for brief cold spells. Low confidence.
Precipitation: around normal, possibly slightly wetter in the east and uplands. Low confidence.
General pattern: alternating high-pressure phases and unsettled returns. Colder outbreaks linked to a weakened polar vortex remain possible, particularly late in the month.
Winter 2025–2026: summary
A slightly milder-than-average winter with a mean anomaly of +0.5°C to +1.0°C. Precipitation near seasonal norms overall — drier in December, wetter in January.
Dominant scenario: frequent Atlantic influence, regular disturbances, cold spells generally short-lived. La Niña and a potentially weakened polar vortex may still promote sharper wintry episodes, especially in January, without altering the overall mild signal.
