Trader consensus on Polymarket reflects tight uncertainty in National Weather Service forecasts for Seattle's highest temperature on March 27, with ensemble models like GFS and ECMWF projecting peaks of 54-57°F amid persistent marine layer clouds and cool northerly flow from a lingering upper-level trough over the Pacific Northwest. Recent 00Z model runs slightly favor 56-57°F (38%) over 54-55°F (34.5%) due to subtle ridging potentially thinning stratus clouds by afternoon, allowing brief solar heating, though overcast skies and Puget Sound moderation cap upside risk. Climatological March highs average 55°F, aligning with this clustering; watch tomorrow's 12Z updates for refinements as boundary layer stability evolves. Lower bins trail on historical rarity of sub-54°F late March maxima under current jet stream patterns.

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.
