Korean Meteorological Administration forecasts confirm a maximum temperature of 13°C in Seoul on March 27, anchoring trader consensus at a 99.9% market-implied probability for this outcome. This positioning reflects the latest model runs from KMA, ECMWF, and GFS ensembles, which show tight agreement amid cool northerly airflow, high-pressure ridging, and cloudy conditions limiting solar insolation—aligning with recent daily highs of 10-12°C. Observational data from surface stations and upper-air soundings further support subdued warming potential. While inherent forecast uncertainty persists, scenarios challenging this include sudden southerly wind shifts or prolonged clear skies boosting daytime heating by 2-3°C; however, current synoptic patterns render these low-probability. Hourly observations will refine resolution as the date unfolds.
