Recent National Weather Service forecasts and supporting model guidance position mostly sunny conditions with a high near 98°F for Houston on August 25, driven by persistent mid-level ridging that has sustained triple-digit heat indices and limited cloud cover or moisture. Southwest flow and mixing of drier air aloft support peak readings in the upper 90s to low 100s, consistent with recent observed highs of 99–101°F and climatological August extremes above 100°F. Low precipitation chances (under 10%) and ongoing Heat Advisory reinforce the outlook, though afternoon model updates or minor steering changes could shift the precise maximum within the 96–99°F range that currently dominates trader-implied probabilities.
