Recent National Weather Service forecasts and ensemble model runs position 88–91°F as the leading outcomes for Houston’s August 10 high, reflecting expected afternoon sea-breeze convergence and scattered thunderstorms that typically cap temperatures below seasonal peaks near 95°F. Persistent upper-level ridging supports warmth, yet increasing low-level moisture and 30–40% storm chances favor modest cooling relative to drier analogs. Historical August climatology shows similar setups yielding highs in the upper 80s to low 90s when convection develops by midday. Traders are monitoring the 12Z model suite and NWS Houston updates for any shift in steering flow or instability that could allow clearer skies and a push toward 92°F or higher.
