Fair Value Reasoning:

Although the median forecast for Incheon Airport (RKSI) remains centered at 9°C (~48°F), market dynamics in the last 24 hours indicate a shift towards the warmer side. The implied probability of '10°C' has risen significantly (from 13% to 24%), while '8°C' has receded. This suggests that as we approach T-24h, high-resolution short-range models may be indicating a slightly delayed cold front passage or increased solar insolation, raising the likelihood of hitting 50°F (10°C). While 9°C (from 48°F/8.89°C) remains the statistical favorite, '10°C' now holds higher fair value than '8°C' due to this momentum.

Rule Risk

There is a notable discrepancy between the title and the rules. The title refers to 'Seoul', but the resolution specifically designates 'Incheon Intl Airport Station' as the source. Incheon is a coastal city ~50km from downtown Seoul, and its weather often differs (typically cooler/windier). Traders checking generic 'Seoul weather' instead of 'Incheon Airport' data risk misjudgment. Additionally, resolution relies on Wunderground's specific reporting, subject to integer rounding rules.

Movers

Mar 17, 2026 - Mar 18, 2026, '10°C' surged from 13c to 24c. As the forecast window entered T-24h, new data likely suggested a weaker or delayed cold front, prompting a repricing of the warmer shoulder (10°C) with capital rotating out of 8°C. Mar 15, 2026 - Mar 17, 2026, '8°C' saw a violent V-shaped recovery (27c->10c->32c) while '12°C' crashed from 22c to 1c. This reflects the market's capitulation on early 'warm week' hopes to a confirmed cold front scenario, followed by a rational recovery from panic-selling (betting on 6°C) back to the forecast mean.
