Trader consensus assigns a 99.7% implied probability to a 21°C high temperature in Shanghai today, driven by the China Meteorological Administration's (CMA) midday observational data and forecast guidance confirming mid-afternoon peaks at this level amid overcast skies, light southerly winds under 12 km/h, and a stabilizing high-pressure ridge. This positioning exceeds March climatological averages of 13–15°C highs, reflecting mild spring patterns validated by international model ensembles converging on 21–22°C maxima with low precipitation risk. While persistent cloud cover caps solar heating, realistic challenges include unexpected clearing for minor urban heat amplification toward 22°C or a late cool front dipping below; official CMA station reports finalize the daily maximum this evening.
