Seattle's weather on April 20 will be tracked through the National Weather Service's official high temperature reading for the day. The prediction market is asking whether Seattle's daily high temperature will fall within the narrow 44-45°F band—a specific and measurable outcome that depends on real-world meteorological conditions. With current odds at 0%, the market assigns zero probability to this outcome, suggesting traders believe Seattle's temperature will either exceed 45°F or fall below 44°F on April 20. This tight price band reflects the weather's inherent unpredictability and the difficulty in pinpointing exact temperature ranges one day in advance. The market closes at midnight UTC on April 20, giving traders less than 24 hours to assess updated weather forecasts from multiple sources and adjust their positions accordingly. Historical April temperatures in Seattle typically range from 45-60°F, so the 44-45°F band represents cooler conditions than the seasonal average, making it a less common outcome. The current 0% odds indicate strong market consensus that this specific narrow range won't materialize, though weather predictions can still surprise. Trading volume of $3,640 and total liquidity of $32,646 show active participation from experienced traders in this daily temperature prediction market.
