Latest ensemble forecasts from NOAA's Global Forecast System and European Centre models point to a Seattle high of 50-51°F on March 25 as the leading outcome at 42.5% implied probability, driven by persistent cool marine air from the Pacific and a stalled upper-level trough over the Northwest suppressing temperatures. Trader sentiment reflects NWS Seattle/Tacoma point forecasts hovering near 50°F amid cloudy skies and light precipitation risks, aligning with March climatology where daily highs average 55°F but frequently dip into the upper 40s during La Niña-influenced springs. Recent 12-18 hour model updates show minimal warm-up potential, tightening odds around 48-53°F bins while extremes fade due to stable boundary layer conditions.

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.
