An incoming early-September Pacific storm system is the dominant driver suppressing Seattle's September 2 high temperature, with National Weather Service and private-model consensus pointing to widespread cloud cover, periods of rain, and south winds limiting daytime heating. This setup favors a daily maximum in the mid- to upper 60s—well below the 1991–2020 climatological average of 73.9 °F—while reducing the likelihood of readings near or above 70 °F. Recent model runs and updated zone forecasts issued September 1 reinforce this cooler, breezy regime, aligning with the market's heaviest weighting on the 64–69 °F bins. Traders are effectively pricing the high probability of marine-layer influence and reduced insolation rather than any return to late-summer warmth.

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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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.
