Forecast models from the National Weather Service and private sources project a Thursday high in the mid-to-upper 90s for Houston, with 30% afternoon thunderstorm chances introducing uncertainty around peak readings. Abundant Gulf moisture keeps dew points near 70°F, sustaining high heat indices near 105°F even if daytime maxima moderate slightly from the prior 100–101°F days, while southwest winds and partial cloud cover limit further intensification. The closely matched 94–95°F and 96–97°F market shares reflect this narrow expected range and potential for brief convective cooling versus clearer-sky warming, consistent with late-summer climatology where isolated storms often cap temperatures before they reach triple digits. Updated model runs and radar trends ahead of the 27th will refine the most likely maximum.
