Latest National Weather Service forecasts and model ensembles from NOAA position a high of 76-77°F as the trader consensus at 52.5% implied probability for San Francisco on March 27, driven by a persistent upper-level ridge of high pressure over California fostering clear skies, light winds, and above-normal temperatures. This setup follows a week of warming trends, with recent soundings showing minimal marine layer influence and strong subsidence inhibiting cloud formation. Ensemble guidance from GFS and ECMWF models converges on mid-to-upper 70s peaks, though slight disagreements exist on peak intensity, reflected in 25.5% odds for 74-75°F and 22.6% for 78-79°F. Updated 12z model runs expected later today could refine these probabilities amid inherent forecast uncertainty from coastal influences.

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.
