Latest GFS and ECMWF forecast ensembles project Seattle's highest temperature on April 4 clustering around 58-63°F—slightly above the early-April climatological normal of 57°F at Sea-Tac Airport—driving trader consensus across those closely matched outcomes at nearly 80% implied probability combined. This positioning stems from NOAA's March spring outlook favoring above-normal temperatures and below-normal precipitation for western Washington, as fading La Niña transitions to ENSO-neutral conditions allow a strengthening upper-level ridge over the Pacific Northwest to promote downslope warming. Key differentiators include variability in Puget Sound marine stratus persistence, which could suppress peaks by 3-5°F if low clouds linger, versus clearer skies enabling diurnal mixing to 62°F+. New 00z and 12z model runs, plus NWS Seattle forecast discussions, will clarify amid inherent 5-day forecast uncertainty.

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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
