Seattle's weather on April 19 will be tracked to determine if the day's highest temperature falls within the 48-49°F range. This prediction market captures traders' expectations for this specific temperature band during spring. In mid-April, Seattle typically experiences mild spring conditions with high temperatures ranging from the mid-50s to low-60s Fahrenheit, making a high of 48-49°F relatively cool and seasonally unusual. The current market price at 0% YES odds suggests traders assess this outcome as extremely unlikely based on historical temperature patterns and weather forecasts approaching April 19. This narrow two-degree temperature band requires precision—the market resolves YES only if the recorded highest temperature at Seattle-Tacoma International Airport falls between 48-49°F inclusive on that date. Given typical spring conditions in the Pacific Northwest, traders are pricing in temperatures notably warmer than this specific range. The market reflects real-time consensus as April 19 approaches, with sufficient liquidity allowing traders to adjust positions based on updated weather forecasts, seasonal patterns, and changing atmospheric conditions in the region.
