Recent National Weather Service and model guidance for September 6 highlight a marine-influenced air mass with increasing clouds, a 40-50% chance of showers or thunderstorms, and light onshore flow that limits nocturnal radiative cooling. Overnight lows are projected mainly in the upper 60s to low 70s, consistent with recent climatology near 64°F but moderated by elevated humidity and reduced clear-sky heat loss. These conditions create tight differentiation among 68–73°F bins, as small shifts in cloud timing, precipitation coverage, or boundary-layer mixing can alter the minimum by a few degrees. Trader sentiment remains dispersed because ensemble spreads show comparable support for mid- to upper-60s versus low-70s outcomes, with lower probabilities assigned to extremes outside historical September ranges. Updated model runs tonight will likely refine the overnight temperature trajectory before resolution.
