**Clear skies and light northerly winds are supporting a typical early-fall overnight low near 52–54°F in Seattle on September 17, 2026, aligning with the market’s leading 54–55°F outcome at 53% implied probability.** National Weather Service and model guidance show radiational cooling under high pressure with minimal cloud cover and dew points in the low 50s, producing minimum temperatures consistent with the September climatological average of ~53°F at Sea-Tac. Recent observations (lows of 52–54°F on the prior two nights) and current model runs reinforce this range, while the 26% probability assigned to 45°F or below reflects the low historical likelihood of strong cold-air advection this early in the season. Higher bins (64°F+) capture residual uncertainty around measurement timing or localized urban heat effects but remain secondary given the consensus forecast. Updated NWS briefings and any overnight model revisions will be the key near-term drivers for traders.

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.
