**Forecast models from sources like the China Meteorological Administration and international services indicate Jinan’s overnight low on September 9 will likely settle between 13–16 °C, with the tightest clustering around 14–16 °C.** This range stems from partly cloudy to overcast skies, light northeasterly winds, and dry air that limit radiational cooling while preventing significant warming. Minor differences in model timing of cloud breaks and boundary-layer mixing produce the near-even market-implied odds between 15 °C and 16–17 °C outcomes. Historical September averages for the region hover near 18 °C lows, so current cooler, drier conditions under high pressure represent a modest departure that keeps probabilities concentrated in the mid-teens rather than pushing toward higher or much lower thresholds. Updated model runs and official station observations through the night will determine final resolution.
