A new round of thunderstorms will bring the risk of severe weather across parts of Texas and Oklahoma to the lower Mississippi Valley by the middle of the week.
Following multiple rounds of severe weather late last week and over the weekend, the risk of heavy and locally damaging thunderstorms beginning at midweek will impact locations across central and southern Oklahoma, central and eastern Texas, southwestern Arkansas and western Louisiana.
A small number of storms will erupt on Tuesday night across parts of central and western Texas and Oklahoma.
The storms will increase in number on Wednesday.
According to Southern Weather Expert Dan Kottlowski, "A disturbance moving southeastward across the southern Plains could bring the first round of severe storms at midweek."

The storms are likely to organize into a large complex that rolls southeastward into Wednesday night.
"The greatest risk from the storms will be flash flooding, hail and locally strong wind gusts," Kottlowski said.

Cities that could be affected by the storms on Wednesday include Oklahoma City, Dallas, Houston, and Shreveport, Louisiana.
The storms will affect the Interstate 10, I-20 and I-35 corridors.
A significant round of severe storms will erupt over the South Central states late this week and will include a threat of tornadoes.
Those traveling within, to or from the area should anticipate delays from midweek on. People spending time outdoors should be on the lookout for rapidly changing weather conditions. The storms will be most active during the afternoon and evening hours, but there can be some exceptions.
While the severe weather will carry the usual risks to lives and property, the rainfall from repeating storms will be beneficial to areas in long-term drought. Parts of western and central Oklahoma and Texas will receive multiple rounds of rain from the stormy pattern.
