**Cloud cover, persistent rain, and southerly flow from an approaching upper-level low are the main drivers keeping Seattle's September 13 high temperature centered in the low-to-mid 60s.** Official and model guidance from NWS, local forecasters, and ensembles consistently show widespread morning rain tapering to scattered showers or drizzle by afternoon, with highs near 64–67°F—well below the 71°F climatological average. The tight 64–65°F (31%) versus 62–63°F (30%) split in market-implied odds reflects uncertainty in the precise timing of heaviest precipitation and any late-day clearing that could allow modest warming. Stronger southerly winds and high humidity further limit daytime heating, while historical analogs for similar late-summer systems support suppression into the mid-60s rather than the upper 60s or low 70s. Traders are effectively betting on the consensus forecast envelope while acknowledging small upside risks if rain ends earlier than expected.

The resolution source for this market will be information from NOAA, specifically the highest 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.
