National Weather Service forecasts indicate a high near 56°F in Seattle on April 18 under mostly sunny skies, driving the market-implied 99.1% probability for 50°F or higher as trader consensus reflects this strong model agreement from GFS and ECMWF ensembles. This positioning stems from a recent transition out of a stormy, cool onshore flow pattern that suppressed temperatures earlier in the week, now giving way to a building high-pressure ridge fostering typical mid-April mildness—where climatological highs average 58°F and rarely fall below 50°F based on 30-year normals. Realistic challenges include unexpected marine stratus deck development overnight into Saturday, potentially capping highs in the upper 40s via adiabatic cooling, or an abrupt shift in steering winds; watch NWS updates Friday for refined guidance.

This market will resolve to the temperature range that contains the highest temperature recorded at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 18 Apr '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Seattle-Tacoma International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/wa/seatac/KSEA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
