Trader consensus on Polymarket heavily favors a Seattle high temperature of 54-55°F (42.5% implied probability) or 56-57°F (31%), aligning closely with the National Weather Service's latest short-range forecast models projecting a peak near 55°F at Seattle-Tacoma International Airport (KSEA) under a building high-pressure ridge over Western Washington. This positioning stems from drier post-frontal conditions, northerly winds capping adiabatic heating, and partly sunny skies following recent shower activity, consistent with late-March climatological normals around 56°F amid typical marine layer influence. Model ensembles like HRRR and RAP exhibit minor spread due to diurnal timing uncertainties, with potential late-afternoon warming or persistent clouds tipping the exact bin; real-time KSEA observations will drive final shifts before end-of-day resolution per Weather Underground data.

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.
