The National Weather Service (NWS) said Saturday that the system would extend across the region for the next several days.
"A wet start to the weekend is in store for southeast Texas and southwest Louisiana as rain/t-storms continue along a stationary front north of the Gulf Coast," the agency tweeted last week. "Slight Risks for excessive rainfall are in effect both Friday and Saturday, with several more inches of rain forecast."
On Saturday, a moisture-rich flow moving north from the Gulf of Mexico is expected to intercept a weak low-level boundary over the region and spur the development of showers and storms through Saturday.
Between 2 to 5 inches of rain are anticipated, leading to some instances of flooding.
In addition, heavy rain is also expected to fall over the Ark-La-Tex region in connection with the slow-moving upper low.
Rain is expected to linger through midweek for many, according to The Weather Channel.
The East Coast and Mid-Atlantic have also seen severe thunderstorms over the past few days.
After wildfire threats and extremely hot temperatures across the Pacific Northwest – also threatened by historic drought – the Cascades region will feel some relief as a couple of Pacific disturbances pass overhead.
