Trader consensus favors 18°C at 28% implied probability, edging out 19°C at 25.5%, driven by the latest ECMWF and GFS ensemble forecasts pinning Shanghai's March 22 high near 18.2°C amid a mild southerly flow. Differentiating factors include subtle model divergences: ECMWF leans warmer with stronger solar insolation under partly cloudy skies, while GFS incorporates a lingering weak cold front capping peaks at 17-18°C. Shanghai's urban heat island effect adds ~1-2°C above rural baselines, against a March climatology averaging 13-15°C highs. Uncertainty stems from timing of any afternoon convection, with final CMA guidance due midday March 21 expected to sharpen odds before diurnal max observations from official stations resolve the market.
