Official measurements from National Weather Service stations in Seattle recorded a daily maximum of 70-71°F on September 20, driving the market's decisive 100% consensus on that bin. Late-summer marine air influence and typical Pacific Northwest cloud patterns kept temperatures near the long-term September average of roughly 70°F, with no heat-wave signals in regional model guidance. Post-event verification by NOAA eliminates most forecast uncertainty, though minor revisions could theoretically arise from station selection criteria or data-quality flags. Traders priced in this outcome rapidly once preliminary observations aligned with climatological expectations.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksea
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
