Official National Weather Service forecasts and model consensus point to a high in the mid-to-upper 90s for Houston on August 28 under mostly sunny skies with only a 20% afternoon thunderstorm chance. Light easterly winds, strong late-summer insolation, and subsidence beneath subtropical high pressure favor efficient daytime heating, while modest dew points near 70–75°F limit evaporative cooling. The narrow spread between 96–97°F (47.5%) and 94–95°F (41%) reflects uncertainty in exact peak timing, any brief convective cloud cover, or minor model temperature biases that could trim or add a degree or two before the daily maximum is recorded. Afternoon observations and updated short-range guidance will clarify the outcome.
