Scattered showers and thunderstorms will continue to plague southeast Texas through the first half of the weekend.
The heaviest rain will fall east of Houston, especially along the coast between Galveston and Beaumont and into coastal areas in Louisiana. Two to four inches of rain is likely between Friday evening and Saturday afternoon in this area. To the west of Houston rainfall totals will be much lower -- averaging closer to a half inch in most places.
Localized flooding is very possible where the heaviest downpours happen. Rainfall rates in some of these storms could easily exceed 2 to 3 inches per hour, which can cause ponding on roadways. Be very careful if you're behind the wheel in a heavy downpour. Drive slowly and never drive through a water-covered roadway.
Because of the rain temperatures will stay low, in the 80s, on Saturday.
Rain will taper off Saturday afternoon and Sunday. A 40 percent chance of scattered showers and storms will continue for the middle of the holiday weekend, and the risk of flooding will be minimal. Temperatures on Sunday will be near 90 degrees.
Labor Day still looks like the driest day of the weekend. Temperatures will return to normal levels, in the mid 90s, with partly cloudy skies and only a 20 percent chance for showers.
