Trader consensus on Polymarket prices a 40.5% implied probability for a 68-69°F high in Los Angeles on May 2, driven by the National Weather Service's latest forecast guidance indicating a persistent marine layer of stratus clouds along the coast, fueled by cool Pacific sea surface temperatures around 60°F and moderate onshore flow. This low-level inversion, observed at 1400-4000 feet deep overnight, suppresses daytime heating and limits burn-off, positioning 66-67°F (28.5%) as the next likely outcome amid model consensus from NOAA's GFS and ECMWF runs showing highs in the upper 60s. Recent developments include yesterday's return of widespread coastal fog after a brief clearing, aligning with typical "May Gray" patterns that historically shave 5-10°F off climo averages near 72°F at LAX. New 12Z model updates and evening NWS discussions could refine clearing timing, introducing uncertainty for 70°F+ scenarios.
