Overview
- Operational forecasts and the DWD ten-day outlook show temperatures rising from about July 8–10 with many regions reaching 27–35°C and some model runs peaking near 38°C.
- The European ECMWF model projects a blocking 'Omega' high that would sustain widespread hot, dry conditions into mid‑July and raise the chance of tropical nights in the south.
- The U.S. GFS model offers a contrasting scenario that keeps the atmosphere more disturbed and suggests earlier thunderstorms and localized heavy rain could interrupt the heat.
- Researchers warn that soils are already very dry so short, heavy storms would not refill groundwater or reservoirs and returning heat would heighten drought stress for farms, forests and water supplies.
- Forecast confidence falls after about July 14, leaving the length and intensity of any prolonged heat uncertain and making water managers and farmers face elevated risk depending on which pattern wins out.
