Trader consensus overwhelmingly favors a Seattle high of 56-57°F on March 20 (99.2% implied probability), driven by the latest ensemble forecasts from NOAA's GFS and ECMWF models, which converge on mild, stable conditions under persistent marine layer influence and weak high-pressure ridging. Historical March data supports this, with Seattle's average highs around 55°F and recent observations showing consistent 50s amid Pacific Northwest's typical spring variability. Verified Seattle NWS point forecasts align precisely, projecting 56°F peaks with low wind and partial cloud cover minimizing diurnal swings. Realistic challenges include an abrupt atmospheric river surge or downslope warming from easterlies, though current upper-air patterns make such shifts unlikely below 1% odds.

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.
