**Strong forecast consensus points to a 50-51°F overnight minimum in Seattle on September 20.** National Weather Service and model guidance project clear to mostly clear skies after daytime highs in the upper 60s to low 70s, with light northerly winds allowing radiational cooling to produce lows in the lower to mid-50s. This aligns closely with the 93% market-implied probability for 50-51°F. Historical September averages near 51°F provide additional context, while the absence of marine layer intrusion or cloud cover tonight reduces downside risk. Minor shifts in dew points or localized fog could still nudge readings into the upper 40s, though current observations and short-term guidance make that scenario less likely.

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.
