Divergent global forecast model ensembles drive the closely matched market-implied probabilities for Shanghai's highest temperature on April 4, with GFS and ECMWF means near 18-20°C but spreads exceeding 8°C across members, accommodating the top outcomes of 24°C or higher (27%), 14°C or below (25%), and 20°C (23%). Recent late-March warm spells in northern China signal potential southerly flow and clear skies pushing highs above 20°C, while persistent risks of cold frontal passages from Siberia—common in early spring baroclinic zones—could suppress temperatures below 15°C under cloudy, showery conditions. Shanghai's April climatology averages 18°C highs with high daily variability from East Asian jet stream influences. Traders await China Meteorological Administration updates and fresh 00Z model runs for resolution clarity.
