Current official forecasts from sources including the China Meteorological Administration and international models indicate a daily maximum of 23°C in Shanghai on May 24 under persistent cloud cover, scattered thunderstorms, and limited solar heating, aligning with the market's near-100% implied probability for that exact outcome. These conditions stem from a moist, stable airmass suppressing typical May warming, where climatological highs average 24–25°C. Trader consensus reflects the strong agreement across updated model runs on this threshold, with minimal upside risk from rapid clearing or reduced precipitation. A late-day break in clouds or stronger insolation could still push readings to 24°C or higher before resolution.
