Trader consensus on Polymarket tilts toward mid-70s highs for San Francisco on March 27, with 72-73°F (19.5%) edging 74-75°F (18%), driven by NOAA's GFS and ECMWF ensembles forecasting 72-76°F amid a building high-pressure ridge over California. This setup promises sunny skies and light onshore winds allowing marine layer burnoff by midday, boosting temps above the March average of 63°F. Differentiating factors include model spread on stratocumulus persistence—earlier clearing favors 74-77°F (34% combined), while stubborn fog caps at 70-73°F—and subtle jet stream shifts, per latest 00Z runs. Historical precedents show similar ridges yielding 72-75°F ~40% of Marches since 1990, underscoring tight odds amid 2-3°F forecast uncertainty.
