Recent forecasts from multiple models indicate overnight lows in Jinan around 17–20°C under partly cloudy skies and light southerly winds, supporting the tight market split between 15°C and 12°C-or-below outcomes. Radiative cooling under clearer patches could drive the daily minimum lower than daytime readings near 29–30°C, while increased cloud cover or mixing from 5–9 mph winds would limit drops. Humidity near 50% and dew points in the mid-teens further moderate surface cooling rates. With the calendar day still underway, updated evening observations from local stations will determine whether the minimum settles near 15°C or dips to 12°C or below amid typical September variability in the North China Plain.
