Description

This event tracks the lowest temperature recorded in Philadelphia on a specific future date, using official government data. The outcome depends entirely on the exact temperature reading reported by the National Weather Service after the date occurs.

Kalshi

All markets resolve based solely on the official minimum temperature recorded in Philadelphia on August 4, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 61° or below, 62-63°, 64-65°, 66-67°, 68-69°, or 70° and above. The National Weather Service's report is the definitive source, and traders must use the latest version available after the date. Preliminary data from other services may differ due to rounding or conversion nuances, so only the official NWS report determines resolution. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to Yes based on where the actual temperature falls within these defined ranges.
