**Persistent high pressure and abundant sunshine are positioning Houston for another hot day on August 22, with National Weather Service and private forecast models converging on a maximum near 100–102 °F at official stations.** Light southwesterly winds, dew points in the low-to-mid 70s, and minimal cloud cover through midday support strong surface heating, while a modest afternoon thunderstorm risk (20 % chance) could briefly cap peaks depending on timing and coverage. Recent model runs show little day-to-day change from the current heat wave, with historical August maxima in the upper 90s to low 100s providing climatological context. The market’s emphasis on the 98–101 °F range reflects trader assessment of these variables and the narrow window for resolution tomorrow, with any earlier or stronger convection representing the main downside risk to higher outcomes.
