ABC13 Weather Watch: Thunderstorms could bring street flooding Friday

HOUSTON, Texas (KTRK) -- A Flood Watch will kick in at 3 a.m. Friday and last until 4 a.m. Saturday, according to the National Weather Service. A front is stalling out over Southeast Texas, and when you combine that with an upper-level system coming in from the west, widespread heavy rains could lead to street flooding on Friday. Small streams, creeks, and even rivers could flood, too. Severe weather is also possible for a portion of Southeast Texas.

We expect multiple rounds of rain, including widespread showers for the morning commute. The wave of storms arriving in the late afternoon and evening could also include hail.

Why is there an ABC13 Weather Watch for Friday?

While there's the chance for severe storms in parts of Southeast Texas Friday, there's a greater risk for street flooding given the widespread, heavy rain predicted. Multiple rounds of showers and storms with rainfall rates of 1 to 2 inches an hour could eventually build up during the day, leading to street flooding and urban flooding of low-lying and poorly drained areas. The Weather Prediction center also highlights most of Southeast Texas with a slight risk for flash flooding Friday.

Where is severe weather possible on Friday?

Severe weather is possible along and south of the stalled front. The front is expected to be stalled out near the coast or offshore most of the day, but that could change late in the afternoon. A wave of low pressure will develop along the boundary and start to push it back inland toward the I-10 corridor. So there is a small chance rotating storms could develop between I-10 and the coast Friday afternoon and Friday evening. These storms could produce severe wind gusts, large hail, and even a tornado. The chances for severe weather are low, but it is a possibility to know about when making your plans.

So where does that leave us for weather this weekend?

With the front pushing fully offshore sometime Friday night, any rain lingering behind the front should clear out pretty quickly before sunrise Saturday. Cooler air flowing in on a north breeze will bring a morning low in the 50s and an afternoon high in the 70s. Sunday also looks spectacular with sunshine warming temps from the mid 50s into the upper 70s!
