Trader consensus in the Seattle lowest-temperature market centers on the low-to-mid 50s°F, with 52–55°F bins capturing nearly 70% of implied probability. National Weather Service and NOAA model guidance for September 6 show mostly clear to partly cloudy skies under weak high pressure, promoting overnight radiative cooling after daytime highs near 70–74°F. Light northerly winds and dew points in the low 50s support minimum readings around 52°F at Sea-Tac, consistent with recent climatology and the past several nights’ observed lows. Ensemble spread and local urban-heat effects introduce modest uncertainty between the 50–51°F and 54–55°F outcomes, while the next model update cycle later today offers the primary near-term catalyst for any shift in positioning.

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.
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.
