Overview
- ECMWF guidance from early February shows a high frost probability from February 9, reaching up to about 95% in parts of northern Germany.
- Meteorologist Dominik Jung says a polar‑vortex split between February 11 and 14 would favor sustained cold with below‑average temperatures, widespread frost and possible snow lasting days to weeks.
- An alternative scenario projects a stabilized vortex with Atlantic lows and mild southwest flow, bringing around 8–14°C, locally up to 16°C, from roughly February 13 to 16.
- Two long‑standing Valentine’s Day proverbs conflict—one linking a cold 14 February to an early spring, the other to a prolonged winter—highlighting the month’s transitional nature.
- The Paulustag rule on February 10 associates a mild day with a windy spring, and current DWD outlooks for Saturday point to snow or sleet with 0–4°C by day and frost near –6°C at night without resolving which path wins.
