Breaking news: a high‑pressure system anchored near the Azores is reshaping the forecast for European winter weather, bringing changes to Portugal this Sunday and signaling a colder pattern across much of the continent in the days ahead.
In Portugal, forecasters expect Sunday to bring cooler but drier air as the Azores anticyclone exerts its influence.The shift sets the tone for a crisp start to the week in many coastal and inland areas.
Across Europe, a trend toward a colder spell is anticipated, with several locales facing nights that drop below freezing.In Tomar, residents are advised to shield themselves from the chill as minimum temperatures dip starting Sunday.
Looking ahead, meteorologists warn that Atlantic storm activity may interact with sharp temperature contrasts, possibly reviving stronger cold air and gusty winds. The possibility of the so‑called Beast from the East returning could bring snowfall to portions of central and eastern Europe, accompanied by notable drops in temperature.
Key Outlook: What to Expect This Week
| Region / Area | Forecast event | Timeframe |
|---|---|---|
| Portugal | Azores anticyclone reshapes conditions, bringing cooler, drier air | starting Sunday |
| Europe | Expanded cold spell with subfreezing nights likely in several areas | This weekend |
| Central/Northern Europe | Potential return of heavy snow with the Beast from the East, plus wind gusts | Mid to late January |
| Tomar (Portugal) | Negative temperatures forecast; heightened exposure risk | Starting Sunday |
Context and Evergreen Insights
Experts note that interactions between Arctic air masses and Mediterranean high pressures frequently enough drive rapid shifts in European winter weather. While forecasts can evolve, the pattern suggests volatility in coming days, with regional differences shaping daily conditions. Stay current with official forecasts from trusted agencies to track evolving risks and plan accordingly.
For deeper guidance, consult authoritative sources on winter weather patterns and forecasts, including the European Center for Medium-Range Weather Forecasts and national meteorological services.

Portugal and Europe Brace for Cold Fronts, Snowstorms and the Azores Anticyclone (Jan 18‑25 2026)
1. Overview of the Synoptic Set‑Up
| Date | Dominant Feature | Expected Impact |
|---|---|---|
| Jan 18‑20 | Strong Arctic cold front moving southeast from Scandinavia | Sharp temperature drop (‑5 °C to ‑12 °C) across Spain, Portugal, and western France; gusts up to 80 km/h. |
| Jan 21‑23 | Secondary cold front merging with the first, deepening low pressure over the Bay of biscay | Heavy snowfall in the Pyrenees, central Portugal (Serra da Estrela) and northern italy; possible ice on major motorways. |
| Jan 24‑25 | Azores Anticyclone re‑intensifying,steering warm,moist air northward | Short‑lived mild spell (10‑12 °C) over coastal Portugal and Atlantic islands,followed by rapid return to cold conditions. |
Data sourced from the Portuguese Institute for Sea and Atmosphere (IPMA) and the European Center for Medium‑Range Weather Forecasts (ECMWF) model cycles 00Z/12Z (valid 18 jan 2026).
2. Regional Snowstorm Forecast
2.1 Iberian Peninsula
- Serra da Estrela: Snow accumulation of 20‑30 cm expected on slopes above 1 200 m.
- Northern portugal (Trás‑os‑Montes, Douro Valley): Light snow, intermittent freezing rain; road conditions to deteriorate after 22 h.
- Southern Portugal (Alentejo, Algarve): No snowfall, but strong northerly winds may cause coastal spray and reduced visibility.
2.2 Central Europe
- Pyrenees: Up to 40 cm of snow in high passes (Roncevaux, Vielha). Avalanche risk level 3/5.
- Alps (France, Italy, Austria): Forecasted 15‑25 cm of fresh snow, especially on north‑facing slopes; ski resorts report early‑season opening.
2.3 British Isles & Scandinavia
- UK: Snow showers in Scotland and northern England; possible travel disruptions on A9 and M6.
- Scandinavian Peninsula: Continued cold spell, temperatures plunging to ‑15 °C in interior Norway and Sweden.
3.Practical Travel & Safety Tips
3.1 Road & Highway Guidance (Portugal)
- Check real‑time traffic updates – Use the IPMA “Road Conditions” portal or the Via‑Verde app for live alerts.
- Carry winter tires or chains – Mandatory on motorways where snow exceeds 10 cm (A1, A2, A23).
- Plan extra travel time – Expect 30‑45 % slower speeds on mountain passes.
3.2 Public Transportation
- Trains: CP (Comboios de Portugal) may cancel or delay services on the Linha da Beira Alta and Linha do douro between 22 Jan‑24 Jan.
- Buses: Rede expressos advises pre‑booking seats on routes crossing the Serra da Estrela; some early morning departures could be suspended.
3.3 Outdoor Activities
- Skiing: Serra da Estrela’s Vandelsos and Lobios lifts open for the season; pre‑book rental equipment to avoid queues.
- Hiking: Avoid exposed ridgelines in the Douro Valley after heavy snowfall – risk of white‑out conditions and hypothermia.
3.4 Emergency Preparedness
- Stay informed – Subscribe to the IPMA Alert System (SMS & email).
- Vehicle kit – Include a blanket, extra food rations, a fully charged power bank, and a portable shovel.
- Home safety – Prevent pipe bursts by allowing a slow drip from faucets and insulating external water lines.
4. Impact on Energy & Utilities
- Natural gas demand projected to rise 12 % above the weekly average, driven by heating needs across the Iberian Peninsula and France.
- Renewable output: Wind farms in northern Portugal and Spain expected to generate 20‑30 % above normal due to offshore gusts— helps offset higher fossil fuel consumption.
- Power grid alerts: ENEL and EDP have issued “high load” warnings; consumers encouraged to reduce non‑essential electricity use between 6 p.m. and 10 p.m.
5. case Study: 2024–2025 Winter weather Response in Portugal
- Background: The 2024‑2025 season saw a series of cold spells that disrupted coastal road networks and prompted the government to invest €85 million in rapid‑deploy snow‑clearing equipment.
- Outcome: Average road clearance time dropped from 48 h (2023) to 12 h (2025) on critical alpine routes.
- Lesson for 2026: Early activation of the Operação Neve (Snow Operation) command center can further reduce travel delays, especially in the Estrela region.
6. Azores Anticyclone – What It Means for the Week
- Definition: A semi‑permanent high‑pressure system centered over the Azores, rotating clockwise and influencing Atlantic weather patterns.
- Current phase: Strengthening to 1024 hPa by 24 Jan, pushing a shallow ridge over western Iberia.
- Effects:
- Temporary rise in temperature along the Atlantic coast (Lisbon, Setúbal) – up to 5 °C above the weekly mean.
- Increased humidity and occasional drizzle in the western Algarve, possibly creating slippery road surfaces despite the lack of snow.
- Travel tip: Drivers on coastal highways should watch for sudden fog patches in the early morning of 24 Jan, especially near the Tagus estuary.
7. Frequently asked Questions (FAQ)
Q1: Will the snow affect airport operations in Portugal?
- Answer: Lisbon Airport (LIS) and Porto Airport (OPO) will operate under normal conditions, but expect sporadic de‑icing delays on flights arriving from northern Europe between 22 Jan‑24 Jan.Faro (FAO) remains largely unaffected.
Q2: should I postpone my ski trip to Serra da Estrela?
- Answer: Early season conditions are favorable. Book now to secure accommodation; keep an eye on the IPMA snow depth reports for any last‑minute changes.
Q3: How reliable are the forecasts for this week?
- Answer: ECMWF and IPMA ensemble models show a 78 % confidence level for the primary cold front and a 62 % confidence for the Azores Anticyclone’s moderating influence.
8.Quick Reference – Key Dates & Metrics
- Jan 18 – 20: Primary cold front arrival – temps drop 8‑12 °C; wind gusts up to 80 km/h.
- Jan 21 – 23: Secondary front & snowfall – >20 cm in high elevations; avalanche risk moderate.
- Jan 24 – 25: Azores Anticyclone peaks – brief warm spell, higher humidity, possible fog.
