Tight odds across 14–21°C reflect model uncertainty following Beijing's recent cold snap, with snow on March 22 suppressing temperatures but potential diurnal warming driving trader splits. China Meteorological Administration and ECMWF ensemble forecasts cluster around 13–16°C highs, citing lingering northerly winds (10–15 km/h) and partial cloud cover limiting solar insolation, yet GFS variants hint at 18–20°C if skies clear faster. Historical March 23 averages (14°C) and urban heat island effects in Beijing further blur lines, as small shifts in boundary layer mixing differentiate outcomes; upcoming hourly CMA updates at 18:00 UTC could catalyze shifts. Trader consensus implies 25–27% odds for mid-teens, hedging volatility.
