**Persistent heatwave conditions driven by a strong high-pressure ridge are elevating overnight minimum temperatures across Los Angeles, positioning 86°F or higher as the leading market outcome.** Clear skies and low humidity are reducing radiative cooling rates overnight, with National Weather Service and ensemble forecasts showing Tuesday's low in the mid-60s to mid-70s range rather than typical early-October values near 61°F. Southwest winds and continued daytime highs above 100°F further limit temperature drops, keeping the implied probability of sub-80°F readings lower. Updated model runs through October 5 show minimal day-to-day cooling before any frontal passage, aligning trader consensus with skin-in-the-game assessment of these stable atmospheric conditions.
