The overnight low temperature in Philadelphia on June 3, 2026, will be recorded by the National Weather Service.
Major weather pattern shifts, seasonal climate anomalies, and updated atmospheric forecasts from the National Weather Service will drive price movement. Cold fronts, high-pressure systems, or unusual jet-stream positioning in early June 2026 could significantly alter trader expectations. Additionally, historical temperature data releases, long-range model consensus changes, and any unusual solar or oceanic activity affecting North American weather patterns may shift the implied probability of each temperature range on Kalshi as the event date approaches.
