Trader consensus on Polymarket heavily favors highs of 17–19°C for Shanghai on March 28, driven by the latest ensemble forecasts from ECMWF and GFS models, which cluster around 18°C amid a mild high-pressure ridge over eastern China. This reflects a synoptic pattern featuring weak southerly flow displacing recent cooler air masses, tempered by partial cloud cover that caps peaks. Differentiating factors include model spread from urban heat island effects in Shanghai—boosting 19°C odds—and slight overperformance of GFS warmth in prior days, versus ECMWF's conservative bias; historical late-March averages hover at 16–18°C, with low risk of extremes per NOAA analogs. Key watch: CMA's 6 PM update today could shift implied probabilities.
