Will the highest temperature in Seoul be 19°C or higher on April 3?

Analysis

Market consensus at 11.5% probability appears well-calibrated given forecast convergence. ECMWF/GFS ensembles project 16-19°C spread with most guidance clustering around 17-18°C due to partly cloudy skies and light winds limiting solar heating. Key factors supporting NO: - KMA short-range forecasts anchor near 17°C vs earlier 20-21°C projections - Variable low-level clouds will cap diurnal heating - Historical April climatology averages 16-18°C - Resolution at Incheon airport may run slightly cooler than Seoul city center - High trading volume ($9K+ daily) suggests informed market pricing While 19°C remains within ensemble spread, probability appears fairly priced at ~12%. Weather forecasting accuracy 1-day out is high, limiting upside surprise potential. Market's heavy weighting toward 16-18°C range (79% combined) reflects meteorological consensus.
