**Persistent cloud cover and scattered thunderstorms are suppressing daytime heating in Houston, driving market-implied odds toward the 82–87°F range for the July 15 high.** Recent model consensus from sources such as the National Weather Service and commercial outlets shows widespread morning to afternoon convection on July 14–15, with 50–70% storm probabilities that limit solar insolation and produce highs several degrees below the 1991–2020 normal of 94°F. This pattern follows several days of unsettled conditions tied to elevated moisture and weak steering flow, which have already delivered highs in the low-to-mid 80s on July 13–14. Key differentiating variables among the tightly bunched leading bins (84–85°F at 31%, 86–87°F at 25%, 82–83°F at 21%) include the exact timing and coverage of storms, boundary-layer mixing, and any late-day clearing that could allow brief additional warming. Higher bins above 88°F carry lower probability because sustained sunshine or a stronger ridge would be required, while sub-82°F outcomes remain unlikely absent an unusually robust outflow or marine influence. Updated short-range model runs and radar trends through the afternoon of July 14 remain the primary near-term catalysts for any further shifts in trader positioning.
