Recent National Weather Service and private model guidance points to a mild overnight period for Seattle on August 30, with the lowest temperature most likely falling in the lower-to-mid 50s. Light winds, partial clearing after daytime highs near 66 °F, and modest dew points should permit efficient radiational cooling under partly cloudy skies, consistent with the climatological average low of 55.5 °F. Traders appear to weigh small differences in forecast cloud cover and boundary-layer mixing that could shift the minimum by a degree or two, keeping the 52–55 °F bins tightly matched near 36–37 % implied probability. Updated model runs and evening observations will refine the exact minimum before resolution.

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.
