Forecast consensus from NWS and models places the overnight low for Los Angeles on August 27 in the mid-70s, with trader odds clustered tightly across the 72–77°F bins due to modest uncertainty in cloud cover and marine layer depth. Persistent onshore flow and elevated humidity limit nocturnal radiative cooling, while variable low-level stratus and light winds could trim or add a degree or two depending on timing of clearing. Historical August averages near 65°F at coastal stations underscore how the current warm pattern elevates baselines, yet short-term model spread in boundary-layer moisture keeps the 74–75°F and 76–77°F outcomes competitive. Updated runs overnight will likely refine these probabilities ahead of resolution.
