An early September Pacific storm system is driving cooler-than-average conditions across western Washington, with official National Weather Service forecasts calling for widespread rain, showers, and possible thunderstorms on September 3. This setup favors onshore flow, persistent cloud cover, and limited daytime heating, producing a market-implied high most likely in the mid-60s°F. Ensemble guidance and NWS point forecasts converge on 64–67°F as the most probable range, reflecting uncertainty in exact timing of heaviest precipitation and any brief afternoon clearing that could allow modest warming. Historical September 3 highs average near 74°F, but the storm’s suppression of solar radiation and advection of cooler marine air explain the downward shift. Traders are weighting the 64–67°F bins most heavily because model spread remains modest two days out, while lower probabilities on 68°F+ or sub-62°F outcomes reflect the low likelihood of significant forecast busts before resolution.

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.
