Overview
- Temperatures are set to plunge widely below zero across plains and inland areas, with lows locally between −5°C and −10°C and a high risk of frost and icy roads.
- Northerly winds such as grecale and tramontana will strengthen, increasing the perceived cold, especially across the South.
- New Year’s Eve is forecast to be largely dry in many cities, including Rome, while some mountain areas in Lazio and Abruzzo have already seen snow.
- After New Year’s Day, precipitation is expected to focus on the Centre–South, with snow mainly on the Apennines above roughly 900–1000 meters.
- Models indicate a two‑phase pattern, pointing to milder, moister Atlantic flows from Jan. 2–3, and experts note that a developing Mediterranean low could lower the snowline if it phases with the cold air.
