Latest National Weather Service forecasts and GFS/ECMWF model ensembles project a high near 67-69°F at San Francisco International Airport (KSFO) on April 18, fueling trader consensus for 68°F or higher at 66% implied probability amid reduced marine stratus coverage. Strengthening upper-level ridging offshore promotes northwesterly winds eroding the coastal boundary layer by midday, enhancing insolation and boosting temperatures 2-4°F above the climatological April normal of 66°F. Recent observations show a warming trend since early April's cool, rainy pattern, with highs reaching mid-60s over the past 48 hours under drier subsidence aloft. Uncertainty persists in marine layer persistence; evening NWS forecast discussions and tomorrow's model runs could shift odds as resolution nears.
