South Texas Faces Street Flooding Risk as Cold Front Approaches

Houston residents can expect a transition from mild, damp conditions to much cooler temperatures as a cold front approaches the region later this week, according to Your Gulf Coast Weather Authority.

The weather pattern begins with a cooling trend on Sunday, as temperatures reached the mid to upper 60s across much of the area. Some urban locations saw highs peaking at 70 degrees.

Rainfall remains a factor for several communities in the immediate forecast. Areas southwest of Houston may experience periods of on-and-off showers, with a more pronounced impact expected toward Victoria County.

Heavy Rain Triggers Flash Flooding Across Parts Of South Texas

While much of the Greater Houston area deals with intermittent showers, the threat of heavy rain is more concentrated further south. Your Gulf Coast Weather Authority reported a Level 2 out of 4 risk for street flooding in South Texas on Sunday.

This flooding risk is expected to diminish slightly on Monday, dropping to a Level 1 out of 4 risk. The primary concern for these southern areas remains the potential for sudden accumulation on roadways during heavy downpours.

The upcoming week will maintain a damp character for several days. Monday may bring a few scattered showers, while thick cloud cover is expected to keep afternoon highs within the upper 60s to low 70s.

Tuesday offers a brief reprieve, as rain chances are projected to drop across the region.

Heavy rain, flash flood threat for South Texas

A shift in air mass is scheduled to arrive late Wednesday into early Thursday. This approaching cold front is expected to trigger the development of coastal showers midweek.

Once the front clears the region, temperatures will drop sharply to end the week. Residents should prepare for a sharp contrast in daytime and nighttime conditions.
