The potential for thunderstorms with flash flooding and locally damaging winds will focus from Houston to New Orleans and northward to part of Arkansas at midweek.
On Tuesday, locally severe storms impacted Houston, Dallas, Austin and San Antonio, Texas, Shreveport and Lake Charles, Louisiana, and Texarkana, Arkansas.
Potions of eastern Texas, including Houston have received over 10 inches of rain for the month of May, which is more than double the average amount for the month.
Houston has been hit with drenching, gusty thunderstorms three days in a row, including Memorial Day. Both Tuesday and Wednesday morning, storms brought torrential rainfall. Up to 2 inches of rain fell in 20 minutes in part of the Houston area Wednesday morning.
On Wednesday, the drenching storms will persist over parts of eastern Texas, while repeating locally gusty thunderstorms spread farther east in Louisiana, eastern Arkansas, Mississippi and western Tennessee. As the amount of rain trends upward in this area, the risk of flash and urban flooding will increase.
A small number of the strongest thunderstorms have the potential to allow brief tornadoes to occur. The tornadoes could occur as heavy rain is falling, which will make them hard to see ahead of time.
The storm system will continue to bring heavy rainfall and the potential flooding through the end of the week over a large part of the South Central states.
This is the same storm system that delivered heavy rain to portions of the southern and central High Plains late last week into the Memorial Day weekend.
While long-term drought conditions continue over much of this area, the rainfall is a big step in the right direction.

Additional rain fell on much of eastern Texas Wednesday morning.
Some areas such as Limon, Colorado; Gage, Oklahoma; Dodge City, Kansas; and Wichita Falls, Texas, managed to receive significantly less rain than their neighbors. Less than 1 inch of rain fell over the duration of the event.
However, much more rain is needed over the summer throughout the central and southern High Plains, but that rain should come.
According to AccuWeather Long-Range Expert Paul Pastelok, “We expect additional rain from the summer monsoon to kick in early over much of the central and southern High Plains and should go a long way to further dent the drought.”
