Recent precipitation and persistent cloud cover across Shandong have moderated overnight radiative cooling in Jinan, keeping minimum temperatures near 20–22°C on August 30. Northeast winds of 2–4 m/s and high humidity limit further drops, while model runs diverge on clearing timing that could allow 18°C or lower versus sustained 22°C-plus readings. Official agency guidance from recent days shows lows stabilizing around 21–23°C amid the post-rain transition, with traders assigning roughly equal implied probabilities across the 16–22°C range reflecting genuine forecast spread and limited historical precedent for sharp late-August dips below 18°C in the region.
