**Official National Weather Service forecasts and supporting model guidance position the highest temperature in Seattle on August 28 in the low 70s.** Persistent morning low clouds are expected to give way to gradual clearing and partly to mostly sunny skies by afternoon under light and variable winds, limiting daytime heating in the region's typical late-summer marine air mass. Current observations on August 27 show highs near 72°F with similar steering patterns, supporting the market's leading 72-73°F bin at 50.5% implied probability and the combined 70-73°F range exceeding 75%. Minor model spread and timing of any late-day marine push create the secondary weighting toward 70-71°F, while upper-70s outcomes remain low-probability given the absence of strong offshore flow or subsidence. Updated NWS guidance and afternoon model runs will provide the next key data points before market resolution.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
