**Current forecasts from NOAA, NWS, and major models converge on a low of 52–54°F for Seattle on September 20, driven by clear to partly cloudy skies, light northerly winds, and dry onshore flow that limits radiative cooling overnight.** This places the market-implied leader (52–53°F at 33.5%) in line with observed trends, as dew points near 52°F and minimal cloud cover support efficient but not extreme nighttime temperature drops typical for late September. The tight clustering with 50–51°F (26.5%) and 45°F or below (32.5%) reflects residual uncertainty in exact minimum timing and microclimate variations at official stations, while higher ranges like 54–55°F (21.5%) remain viable if afternoon warmth lingers longer. No incoming fronts or model divergences are altering this stable pattern, with resolution hinging on the official overnight reading from Sea-Tac or equivalent sites.

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.
