Highest temperature in Chongqing on September 10?

What this question means

Seven values carry real weight here, which is unusual for a one-day forecast. Chongqing on 10 September peaks at just 31% for 30°C, with 31°C at 23%, 29°C at 17%, 28°C at 11%, 32°C at 8%, 27°C at 6% and 26°C at 5%.

That spread across seven degrees puts it closer to the Tokyo question on this board than to the near-spikes of Singapore or Tel Aviv.

Chongqing sits inland in a river basin ringed by hills, a setting known for persistent cloud and fog. Conditions like that make the daily maximum unusually sensitive to whether the cloud breaks, and a forecast cannot easily resolve that in advance — which is exactly what a flat distribution across adjacent degrees looks like.

Worth repeating: flatness here is honesty, not laziness. A crowd spreading probability over seven degrees is correctly reporting that it cannot narrow further.
