Showers and storms are expected to develop along and ahead of an approaching frontal boundary today with the potential for rainfall lasting into late tonight/early Thursday morning. An isolated strong to severe thunderstorm is possible.
- A weak cold front is expected to slowly move through Southeast Texas later today. Scattered showers and storms are expected to develop ahead of the front, and then a line of showers and storms along the front itself.Â
- Timing: Isolated showers and storms may begin to develop as early as sunrise Wednesday morning along the coast, and in Piney Woods as the front approaches from the northwest. The front is expected to pass through the Piney Woods/Brazos Valley between 11am and 2pm, along I-10 between 2pm and 6pm, and then off the coast between 7pm and Midnight. The front may stall near the coast through Thursday morning, continuing the rainfall chances, however, the greatest coverage is expected to be over the coastal waters.
- Impacts: A few of these storms may become strong to severe with the potential to produce locally heavy rainfall and strong wind gusts. The front may briefly linger near the coast going into Thursday morning, leading to the heavy rainfall potential lingering for areas south of I-10. Rainfall rates up to 2-3 inches per hour will be possible, which could lead to isolated street flooding in urban and low-lying areas if these rates occur for an extended period of time. Through Thursday morning, rainfall totals are expected to generally be up to 1-2″ with isolated higher amounts of 3-5″ possible along and south of I-10.
- The Weather Prediction Center has outlined Southeast Texas in a marginal risk of excessive rainfall (level 1 of 4)Â
- The Storm Prediction Center has also outlined portions of Southeast Texas in a marginal risk of severe weather (level 1 of 5)
