Traders have converged on 18°C (99.5% implied probability) for Wuhan's highest temperature on March 21, propelled by consensus short-range forecasts from ECMWF, GFS, and China Meteorological Administration models, which project mild spring conditions with highs stabilizing around 18°C amid light southerly winds and partial cloud cover. Historical data shows Wuhan's March averages 16-19°C, aligning with current positioning after recent cool snaps. This near-certainty reflects low forecast uncertainty at 48-72 hours out, per ensemble spread analysis. Realistic challenges include an unanticipated warm front boosting advection or microscale urban heat effects, though diurnal maximums rarely exceed model ceilings by more than 1-2°C in stable synoptic patterns.
