Recent National Weather Service and ensemble model guidance indicates a stable high-pressure pattern with northeast winds and clear skies over Houston, supporting overnight lows near 70°F for October 9. This reflects typical early-October radiative cooling under dry conditions, with minimal cold-air advection. Market-implied odds favor the 70–71°F bin as the most probable outcome while assigning nearly equal weight to 82°F or higher, highlighting trader uncertainty around the precise minimum amid model spread on boundary-layer mixing and dewpoint trends. Historical climatology places the average low near 66°F, so the current warm bias stems from the absence of frontal passages. Updated short-range model runs and local observations over the next 48 hours will likely tighten the range ahead of resolution.
