Forecasts from multiple meteorological sources indicate clear skies and light northeasterly winds over Jinan on September 5, supporting radiative cooling overnight with minimum temperatures most likely between 17–20°C. This range aligns with early-autumn climatology for the region, where daytime highs near 31–32°C give way to rapid nocturnal drops under high-pressure dominance and low humidity. Model agreement is high on the absence of significant cloud cover or frontal activity that could retain heat, though small variations in wind speed or boundary-layer mixing could shift the exact low by 1–2°C. Trader sentiment remains balanced between sub-13°C and 22°C+ outcomes because resolution hinges on the precise official minimum recorded by local stations, with final data releases expected shortly after the 24-hour period closes.
