Forecast models for Jinan on September 14 point to clear skies and light variable winds overnight, favoring strong radiative cooling that typically sets the daily minimum just before sunrise. Current guidance from multiple sources indicates a low in the 16–19°C range under dry conditions with dew points dropping into the mid-teens, consistent with early-autumn climatology for the region where September averages hover near 17°C. The near-even market split between 22°C-or-higher and 12°C-or-below thresholds, alongside elevated probabilities clustered around 14–15°C, reflects lingering uncertainty across ensemble runs regarding exact timing and intensity of nocturnal cooling versus any residual daytime heat retention. Fresh model updates expected overnight will likely tighten the range ahead of resolution.
