Recent National Weather Service and model consensus forecasts for Seattle on September 6 point to mostly sunny skies with northerly winds and a daytime high near 70°F, aligning closely with the seasonal average of 72.8°F. This drives the market's concentration on 70–73°F outcomes, as current conditions show stable high pressure without incoming fronts or marine layer intrusions that could suppress temperatures. Recent days have featured highs in the upper 60s to low 70s under similar patterns, reinforcing trader confidence in near-normal readings. Minor model spread allows limited probability for 74–75°F if afternoon heating exceeds expectations, while cooler scenarios remain unlikely absent unexpected cloud cover or stronger onshore flow. Updated NWS guidance and real-time observations tomorrow morning represent the key near-term data points.

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.
