Latest NOAA forecast models, including GFS and ECMWF ensembles, drive trader consensus toward a highest temperature in San Francisco on March 28 clustering in the 66-73°F range, with 68-69°F edging out at 22.5% implied probability due to persistent high pressure aloft favoring mild advection of warmer air from inland valleys. Differentiating factors include variable marine layer persistence—potentially capping peaks at 66-67°F via coastal stratus clouds versus brief diurnal clearing allowing 70-73°F spikes—as seen in recent 00Z runs showing a 2-3°F spread in probabilistic outputs. Historical March data at SFO station averages 63°F highs, but current ridging exceeds norms by 4-5°F, heightening uncertainty ahead of afternoon soundings.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the San Francisco International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ca/san-francisco/KSFO.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
