Recent short-range ensemble forecasts from the Korea Meteorological Administration indicate Seoul's overnight low on June 16 will likely settle near 19–20°C, reflecting mild southwesterly flow, moderate humidity, and variable cloud cover that limits radiative cooling. Model consensus shows tight spread within this band, consistent with early-summer climatology where average June minima hover around 18–20°C. The near-even split between the two leading outcomes captures residual uncertainty in final wind speeds and timing of any clearing, with updated KMA runs and station observations expected to sharpen probabilities before the midnight close. Historical analogs confirm such narrow ranges often resolve within 1°C of ensemble means.
