Recent National Weather Service and private model guidance for Houston on August 10 highlight a 30–40% chance of afternoon thunderstorms and a moderating sea breeze, which can increase cloud cover and reduce peak heating below the typical late-summer maximum near 95 °F. These conditions create the main uncertainty separating the tightly bunched 88–91 °F outcomes that together exceed 70% market-implied probability. Historical August climatology at Houston Intercontinental shows daily highs averaging 94–95 °F with modest day-to-day variability, yet convective activity and higher dew points frequently cap temperatures in the low 90s when storms develop. Traders are therefore weighting the latest forecast consensus on timing and coverage of any showers, with resolution depending on the official highest recorded temperature at the primary observing site.
