Tight clustering of market-implied odds around 48-53°F for Seattle's March 25 high temperature stems from ensemble forecasts in GFS, ECMWF, and NOAA HRRR models converging on 49-52°F peaks, reflecting uncertainty in low-level onshore flow and persistent marine stratus over Puget Sound. The 50-51°F bin (28.5%) leads narrowly due to 00Z runs emphasizing cloud-induced suppression of diurnal heating, edging out 48-49°F (26.5%) amid potential boundary layer mixing and 52-53°F (26.0%) if subtle upper-ridge amplification allows midday clearing. Historical March 25 averages near 54°F are tempered by current cool northeast Pacific air mass; traders eye afternoon model updates for resolution-defining tweaks.

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.
