General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update: 2 December 2025 – 12:00
Depression activity will remain concentrated over the Atlantic, with several low-pressure centres moving from the central ocean towards the northwest of the British Isles, before tracking towards the North Sea and Scandinavia from next weekend.
This pattern will keep our region under a mild, mostly quiet southerly flow. From Saturday onward, the flow will shift more to the southwest, becoming more unsettled and windier, while introducing very mild subtropical air into our area.

National Thermal Indicator (Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update: 2 December 2025 – 11 AM
The national thermal indicator, currently between +1 and +2, is expected to rise further in the coming days. Recent outlooks point to an exceptional peak of +9 around 8 December, followed by a gradual decrease to values between +4 and +5.
In practical terms, daily highs will generally range between 5 and 12°C.
However, from 7 to 10 December, an unusually mild spell is anticipated, with temperatures reaching 9 to 16°C, far above what is typical for early December.

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.
