Overview
- Late September brought an unusual warm spell with locally near 30°C temperatures caused by a strong blocking high over Eastern Europe that funneled warm southern air into Germany.
- The cold front tied to a North Atlantic low is crossing the country on Thursday and will push the cooler air in from west to east with showers and isolated thunderstorms.
- The Deutscher Wetterdienst has warned of locally intense rainfall rates of about 20 liters per square meter in one hour, multi-hour totals around 20–35 l/m², and gusty winds with isolated stronger gusts.
- Precipitation will be highly uneven, with western and northwestern regions receiving most rain while many eastern areas stay largely dry, so much of the rainfall will run off or evaporate and will not cure the drought or restore low river levels such as on the Rhine.
- Forecasters expect high pressure to rebuild for a largely sunny and mild 'golden October' weekend, but medium-range model runs show a growing, uncertain risk of a much colder intrusion around October 10–15 that could drop temperatures sharply and bring first snow to high elevations.
