Aggressive analysis indicates a firm NO. While Seoul's 30-year climatological T_min for May 5th averages 10.8°C, pointing to a 'yes' under normal conditions, current long-range model consensus dictates a significant positive deviation. The ECMWF and GFS 00z/12z ensemble means project a robust +4.5°C to +5.0°C 850 hPa temperature anomaly across the Korean Peninsula, driven by persistent warm air advection. A strengthening subtropical ridge at 500 hPa will block any northerly cold air intrusions. Furthermore, boundary layer modeling predicts sustained mid-level cloud cover with >70% probability, severely mitigating nocturnal radiational cooling. The ECMWF ENS T_min probability distribution shows the median solution at 16.2°C, with less than a 20% chance of dipping below 15°C. Sentiment: KMA's extended outlook also highlights above-average thermal profiles. 90% NO — invalid if 850 hPa anomaly drops below +2.0°C by D+3 runs.
