April 20 falls in spring for the Pacific Northwest, a period when Seattle typically experiences warming temperatures. The National Weather Service tracks daily temperature highs across the region, making this market directly resolvable based on published official weather data. At 43°F, the market is pricing in a scenario approximately 15–20°F below what is typical for mid-April in Seattle, where average daily highs generally range between 56–62°F depending on the specific calendar week. This threshold is notably cold for the season—Seattle rarely experiences freezing highs once spring begins in earnest. The current zero percent odds on the YES side suggests the prediction market is pricing in an extremely low probability for such a cold high temperature, a view aligned with historical patterns and current seasonal weather trends in the Pacific Northwest region. Prediction markets on weather outcomes update continuously as meteorologists release new forecast data, pressure system movements, and atmospheric conditions. Traders can adjust positions dynamically based on emerging forecast changes and precipitation likelihood. This specific market resolves automatically once the National Weather Service publishes the official daily maximum temperature recorded in Seattle on April 20, 2026, providing transparent, objective settlement.
