**Forecast models from sources including the China Meteorological Administration and international ensembles indicate overnight lows in Jinan on September 6 near 19–21°C under clear to partly cloudy skies and light northeasterly winds.** This setup limits radiational cooling, keeping the minimum well above seasonal averages for early September while steering clear of the sharp drops that would push readings toward 12°C or below. Trader consensus remains closely split because small differences in wind speed, cloud timing, or urban heat-island effects can shift the exact low by 1–2°C, directly affecting the 16–22°C outcome buckets that together capture nearly half the probability. Updated model runs and official hourly observations on the 6th will provide the decisive data for resolution.
