Current ensemble forecasts from agencies like the China Meteorological Administration show a dominant subtropical high-pressure ridge over eastern China, suppressing cloud cover and limiting nocturnal cooling, which supports market-implied odds favoring a Shanghai minimum of 32°C or higher. Historical July baselines for the city average around 26–28°C overnight lows, but recent model runs highlight above-normal 850 hPa temperatures and weak southerly flow that reduce radiative heat loss. Key upcoming updates from 48–72 hour model cycles could shift probabilities if a frontal passage or increased moisture arrives earlier than projected. Trader consensus reflects this short-term stability while acknowledging typical forecast uncertainty ranges of 1–2°C near the event.
