**Clear skies and light northeasterly winds are supporting efficient nocturnal radiative cooling over Jinan, with forecast minimum temperatures centered near 16–18°C for September 2.** Multiple short-range models, including those from WeatherBug and WindBorne, indicate mostly clear conditions with dew points in the low-to-mid teens Celsius and winds under 5–8 mph, conditions that typically allow surface temperatures to drop close to or slightly below the seasonal average low of roughly 17–18°C. The near-even split between the 12°C-or-below and 22°C-or-higher outcomes reflects trader focus on residual model spread in cloud cover or boundary-layer moisture, which can shift the overnight minimum by 2–4°C. No significant frontal passages or precipitation are expected in the next 24–48 hours, keeping the primary uncertainty tied to the precise evolution of high pressure and radiational cooling efficiency rather than synoptic changes.
