Several factors can shift odds on this market. Updated seasonal climate models and long-range forecasts issued by NOAA or other meteorological bodies may signal cooler or warmer May conditions. Major weather pattern shifts—such as a late-spring cold front or Arctic air intrusion—would trigger immediate repricing. Historical May temperature data and anomalies in Chicago's climate record inform baseline expectations. As May 2026 approaches, medium-range forecasts (10–14 days out) become more precise, allowing traders to refine their bets. Any unusual atmospheric circulation patterns or El Niño/La Niña updates could also influence trader positioning.
