Southeast Texas Heat Persists Through Weekend Before Midweek Cool-Down
August has brought unusually hot weather to much of Southeast Texas. In Houston, the average high this month stands at about 96.7 degrees, roughly 1.5 degrees warmer than normal for this point in August. The city already logged six days with temperatures at or above 100 degrees this month, compared with just one such day through the end of July.
Sunday forecast
Early Sunday will feel comfortable, with morning lows in the mid- to upper-70s. By mid-morning, readings will rise toward 80, and by late morning into the afternoon, highs are expected in the mid-90s. The heat index could push “feels like” temperatures near 100 degrees. Skies should be mostly sunny, with only a small chance of showers in the afternoon. Rain chances will be around 20%, and any storms would be brief with a low risk of flooding.
Monday forecast
Monday mirrors Sunday for the most part. Highs are expected to reach the mid- to upper-90s, around 96–97 degrees, with a similar slight chance of an isolated shower or storm. Most areas should stay dry, but brief, scattered activity can’t be ruled out.
Midweek changes
A strong cold front is forecast to move into North Texas late Monday and Tuesday, delivering noticeably cooler air there—potentially dropping temperatures by as much as 15–20 degrees from Texoma to the Dallas–Fort Worth area. As the front progresses southward, Houston will feel the impact more gradually. Tuesday’s high in Houston is expected to be in the low to mid-90s, while Wednesday could hover near 90 degrees as the front weakens on approach.
Rain chances will rise as the boundary gets closer. Houston may see rain chances of about 30–40% on Tuesday, increasing to around 50% on Wednesday. Some stronger storms could occur near the frontal boundary, but widespread severe weather is not expected.
What this means for your plans
The coming days offer a brief cooling trend, especially for the northern parts of the region, with Houston returning closer to seasonal norms by midweek. Outdoor activities should still plan for heat and humidity, particularly Sunday and Monday, with hydration and sun protection essential. If you’re itching for relief from the heat, Tuesday into Wednesday looks most promising for cooler feels, with a higher chance of rain bringing some welcome moisture.
Summary
August has delivered hot conditions for Southeast Texas, but a strong cold front arriving midweek should bring a noticeable drop in temperatures and an uptick in thunderstorm chances. Expect highs in the 90s or lower 90s by Tuesday into Wednesday, with lingering heat and humidity returning as the front fades.
