Description

This event tracks the highest temperature recorded at Chicago Midway Airport in Illinois on July 16, 2026. The resolution uses the official National Weather Service Climatological Report (Daily) as the authoritative source, which may differ from preliminary reports or third-party weather services due to rounding and measurement methodology variations.

Kalshi

Resolution is determined by the highest temperature recorded at Chicago Midway, IL on July 16, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature reading is divided into six distinct ranges, each corresponding to a specific outcome. Temperatures below 92° resolve to one outcome, temperatures from 92-93° to another, 94-95° to a third, 96-97° to a fourth, 98-99° to a fifth, and temperatures 100° or above to a sixth outcome. The NWS Climatological Report (Daily) serves as the official and final reference for temperature determination. Traders should note that preliminary NWS data and measurements from alternative sources like AccuWeather or Google Weather may differ due to underlying rounding and conversion nuances, and should exercise caution when interpreting such preliminary information.
