**Forecast models and official guidance point to a maximum temperature in Shanghai today centered on 31–32°C amid widespread cloud cover, showers, and southeasterly flow.** Multiple weather services converge on daytime highs of 31–33°C, with rain and thunderstorms expected to limit solar heating and keep readings from climbing higher. High humidity (often 80–90%) and modest wind speeds further moderate peak values, consistent with late-August climatology in the region where monsoon moisture and subtropical influences frequently cap temperatures below clear-sky potential. **This scientific setup explains the market’s strong tilt toward 31°C (57.5% implied probability), followed by 32°C (20%) and 30°C (16.5%).** Traders appear to weigh the consensus forecast range against resolution criteria that record the single highest official reading, incorporating uncertainty from timing of heaviest rain and any brief clearing that could allow a brief spike to 32°C or a cooler outcome near 30°C. Updated model runs and real-time observations through the morning will be the next key inputs likely to refine these probabilities before resolution.
