Trader sentiment for San Francisco's March 24 high temperature hinges on the latest NWS and ECMWF forecasts projecting a high-pressure ridge offshore, fostering subsidence warming and potential marine layer burn-off for highs near 70°F, closely splitting odds between 70-71°F (30.5%) and 74°F+ (29.0%). Differentiating factors include boundary layer mixing efficiency—stronger ridging could yield 74°F via enhanced solar insolation if coastal stratus clears early, per GFS ensemble means of 71-73°F—versus persistent Pacific inflow capping peaks at 70°F, aligning with March climatology (historical median 64°F, 75th percentile 70°F). Model spreads of 3-5°F underscore uncertainty ahead of afternoon observations at SFO.
