Recent showers and an incoming marine layer are the main drivers keeping trader odds clustered across the 52–59°F bins for Los Angeles’ October 12 low. Official National Weather Service guidance projects partly cloudy conditions after morning rain, with lows in the lower to mid-50s as southwest flow and lingering moisture limit overnight radiative cooling. Model spread in clearing timing and marine push strength creates the tight probabilities between adjacent bins, while historical October averages near 60–61°F explain why higher outcomes carry residual weight. Updated NWS briefings and evening model runs will refine the exact minimum before resolution.
