Overview
- American and Canadian model runs depict a northwesterly flow delivering polar air and multiple snow fronts around January 1–6, while ECMWF guidance at times favors a much drier start to the month.
- Under the snowier scenarios, lowlands could see measurable snow and the Alps and central uplands could accumulate roughly 20–40 centimeters, though forecasters caution small Atlantic lows could shift outcomes.
- The German weather service reports the 24–26 December period was the coldest since 2010 and continues to warn of widespread ice hazards after freezing drizzle and overfreezing rain led to numerous traffic accidents.
- Near‑term forecasts keep only intermittent snow in higher terrain with temperatures oscillating around freezing before any sustained pattern change develops.
- A separate winter storm in the U.S. Northeast dropped about 10–13 centimeters in New York City and up to roughly 23–28 centimeters nearby, triggering emergencies in New York and New Jersey and large flight disruptions at JFK, LaGuardia and Newark, according to authorities and FlightAware.
