A storm system out west is expected to send another round of stormy weather into Southeast Texas this weekend, with a cold front sliding into the Houston area late Saturday afternoon into the early evening. Warm, humid Gulf air ahead of the front should fuel showers and thunderstorms, and some storms could dump rain at a rate of 1 to 3 inches per hour.
The heavy downpours could cause brief street flooding in spots that do not drain well, with areas north of I-10 facing a higher chance of isolated high water issues. Widespread flooding is not expected because the storms should keep moving, but Saturday night could still bring a low but real flood threat.
A few showers may hang around early Sunday before drier air moves in behind the front. A noticeable northeast breeze is expected after the front passes, especially near the coast, where winds could get strong at times. High pressure building in with a northerly wind should help lower humidity on Sunday, and highs are expected to settle in the mid to low 70s.
For Southeast Texas, the shift is straightforward: storms Saturday, a lingering shower threat early Sunday, then cooler, less humid air. The biggest concern is not a long-lived flood event, but whether the heaviest cells line up over the same neighborhoods long enough to produce brief high water.
