Recent forecasts from multiple models indicate a mild overnight period into September 19 with minimum temperatures likely settling between 10–12 °C under partly cloudy skies, light southwesterly winds, and high pressure maintaining stable conditions. This setup favors radiative cooling limited by cloud cover and dew points near 9–11 °C, keeping the daily low well above seasonal extremes but below the long-term average high of 19.2 °C. Trader sentiment splits between sub-7 °C and 16 °C-plus outcomes because small differences in boundary-layer mixing, exact cloud timing, or model bias in the final 24 hours can shift the recorded minimum by several degrees; updated runs from agencies like the German Weather Service will clarify whether clearer skies allow deeper cooling or if increasing moisture prevents it. Historical analogs show September 19 lows averaging 9.7 °C, underscoring how current mild advection keeps probabilities balanced near the middle bins.
