Severe Weather Shifts to Shreveport, Memphis Sunday

The southern Plains will finally catch a break from severe weather to end the weekend as the danger shifts to the lower Mississippi Valley.

After Saturday marks the third straight day of severe weather rattling the southern Plains, the threat zone on Sunday will take aim at the zone from southern Missouri and western Tennessee to northern Louisiana and far northeastern Texas.

Within this zone lies Cape Girardeau, Missouri; Little Rock and Jonesboro, Arkansas; Memphis, Tennessee; Tyler, Texas; Shreveport, Louisiana; and Greenville, Mississippi.

"Severe thunderstorms will initially develop across western Arkansas, northwestern Louisiana and northeastern Texas Sunday afternoon," stated AccuWeather Assistant Director of Weather Warning Services Andrew Gagnon.

"These thunderstorms will march eastward across much of Arkansas and northern Louisiana during the late afternoon and will eventually spread into northern Mississippi and western Tennessee during the evening hours," Gagnon continued.

At the same time, the northern extent of the violent thunderstorms will graze southern Missouri during the day and then southern Illinois and far western Kentucky in the evening.

"Little Rock and Shreveport are at risk for severe storms during the afternoon hours with the greatest severe threat arriving in the evening in the Memphis area," added Gagnon.

The severe thunderstorms threaten to bear down on Memphis as the city's Grizzlies host the Portland Trail Blazers for Game 1 of the first round of the NBA Playoffs.

Damaging winds and large hail in excess of an inch in diameter are the greatest threats with the strongest thunderstorms on Sunday afternoon and evening, according to Gagnon.

Blinding downpours will also be produced, and an isolated tornado cannot be ruled out.

Residents are reminded to seek shelter as soon as thunder is heard, regardless of the severity of the thunderstorm. You are then close enough to be struck by lightning.

The severe weather will not only create hazards for residents in the lower Mississippi Valley, but also motorists planning to travel on stretches of I-20, I-30, I-40 and I-55.

Cooler and drier air will replace Sunday's severe weather by Monday, when the threat zone will shift to the central Eastern Seaboard.
