Korea Meteorological Administration's latest short-range forecast points to a daytime high near 26°C in Seoul on May 15 under a building high-pressure ridge bringing clear skies and subsidence warming after May 13's rainfall limited highs to around 20°C. Trader consensus at 44.5% implied probability for 26°C or higher reflects this shift, tempered by ensemble spread in ECMWF and GFS models showing 24–28°C range amid typical May climatological averages of 22–23°C. Recent observational data from KMA stations confirm cooling southerly flows yielding way to drier northwesterlies, with uncertainty in peak afternoon heating. Watch for daily KMA updates and 12-hour forecast refinements through May 14, as urban heat islands could nudge outcomes higher.
