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 13 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Latest GFS and ECMWF ensemble forecasts show Seattle-Tacoma International Airport (SeaTac, KSEA) highs clustering around 55-57°F on April 13, anchoring trader sentiment with 54-55°F at 34% implied probability and 56-57°F close behind at 28%, amid model spread of 2-3°F. This tight contest reflects uncertainty in marine layer persistence and low stratocumulus clouds, which NOAA forecasters note could cap peaks at 54-55°F if onshore flow strengthens, versus quicker afternoon clearing pushing toward 56-57°F in drier runs. Following a season-first 70°F peak on April 6 amid a brief upper-ridge amplification, cooler northwest flow now dominates under ENSO-neutral conditions, aligning with spring outlooks for above-normal temperatures but tempered by coastal moderation. New 00Z/12Z model cycles and NWS updates will sharpen resolution criteria before Sunday's observations.
