Several factors could shift market odds for DC's June 11 high temperature. Seasonal climate patterns and long-range forecasts released by NOAA or other meteorological agencies may indicate warmer or cooler conditions ahead. Major weather systems—such as heat domes, cold fronts, or tropical systems—tracked weeks in advance can influence trader expectations. Urban heat island effects, air quality alerts, or unusual atmospheric circulation patterns may also affect pricing. As June 11 approaches, medium-range forecasts become more precise, typically causing sharper price movements. Real-time weather data and any anomalies in spring or early-summer conditions will drive continuous repricing on Kalshi.
