Ensemble forecasts from NOAA's Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF) form the primary driver of trader sentiment, projecting highs clustering in the mid-to-upper 70s°F at San Francisco International Airport (KSFO)—the market's resolution station—on April 4. This positioning stems from a persistent upper-level ridge lingering after the Bay Area's record-shattering warmest March on record, suppressing marine stratus and promoting diurnal heating despite Pacific sea surface temperatures near seasonal norms. Trader consensus implies a 55.5% probability for 78°F or higher, buoyed by hotter ensemble outliers, while 21.5% backs 76-77°F amid uncertainties like delayed stratus burn-off or sea breeze moderation. National Weather Service updates and fresh model runs expected within 24 hours may refine these odds as short-range guidance sharpens.
