Ensemble weather models from NOAA and ECMWF drive trader consensus toward a Beijing high of 21-22°C on March 28, with implied probabilities tightly clustered as forecasts show low-confidence spread amid variable spring synoptics. Recent runs indicate a dominant ridge amplifying southerly flows and mild advection, pushing above the 14°C March climatological average influenced by urban heat island effects, though a trailing cold front risks clipping peaks to 19-20°C. Differentiators include cloud cover from upstream moisture and jet stream waviness; traders weigh 24% odds on 21°C against 21% for 22°C per latest 00Z updates, awaiting afternoon CMA guidance for resolution criteria met by official Capital Airport observations.
