Traders solidly favor 56-57°F as Seattle's highest temperature on March 18, mirroring the National Weather Service's latest forecast of 55-57°F under persistent marine layer clouds and light onshore flow typical for Pacific Northwest spring. This positioning draws from verified model ensembles like GFS and ECMWF, which converge on mid-50s highs after recent cool snaps, consistent with Seattle's March climatology averaging 55°F since 1991. Historical data shows rare March spikes above 60°F tied to strong ridging, but current upper-air patterns lack such signals. A realistic challenge would require an abrupt high-pressure build or downslope winds accelerating warming, though probabilities remain under 1% per probabilistic outlooks.

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.
