**Latest numerical weather prediction models, including GFS outputs, indicate a daily maximum near 24°C for Shanghai on October 15 under southeasterly flow and increasing cloud cover that limits afternoon heating.** This setup aligns with mid-October climatology, where average highs hover around 23°C, and supports the market's leading 49.5% implied probability for 24°C, followed by 23°C at 28.5%. Minor model spread on exact peak timing or localized urban effects keeps 25°C viable at 16.5%, while colder or warmer outliers remain low-probability given stable pressure patterns and minimal precipitation risk. Official station readings from the China Meteorological Administration will finalize resolution.
