Seattle's marine climate and persistent cloud cover from morning showers on August 29 are keeping the overnight minimum tightly contested between the 54-55°F and 56-57°F bins that together command nearly 80% of market-implied probability. Light southerly winds, elevated humidity near 80%, and reduced radiative cooling under overcast skies limit how far temperatures can fall below the seasonal average low of about 56°F, while any breaks in cloud or lighter precipitation could allow brief dips toward 52-53°F. Official National Weather Service guidance shows lows stabilizing in the mid-50s with minimal model spread, underscoring why traders see the two central ranges as the most probable outcomes given current steering patterns and the moderating effect of onshore flow.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
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.
