Traders see 24–25°C as the most likely peak temperature in Zhengzhou today because persistent cloud cover and widespread showers or thunderstorms are limiting daytime heating. Multiple forecast models show highs in the 23–25°C range under overcast skies with light easterly or southeasterly winds and high humidity, consistent with the seasonal climatology for late September. The tight clustering of probabilities around 24–26°C reflects uncertainty in the exact timing and intensity of precipitation, which can suppress the daily maximum by 1–3°C depending on when the heaviest rain arrives relative to peak insolation. Newer model runs and real-time observations will clarify whether any brief clearing allows a brief spike toward 26°C or keeps readings capped near 24°C.
