Tornadoes in South, severe weather outbreak is ahead this weekend.
An outbreak of severe weather is likely this weekend in the South, including the threat of tornadoes, a few of which may be strong.
As Wesley exits into Canada later Friday into early Saturday, a southward plunge of the jet stream will pivot out of northern Mexico and the Desert Southwest into the Plains states.
Ahead of that jet-stream disturbance, low pressure will form in the South Saturday and gain strength as it pushes northward into the Ohio Valley Sunday. This strengthening low will draw warm, humid air north from the Gulf of Mexico.
This potentially volatile combination of ingredients may give rise to an outbreak of severe thunderstorms across the South this weekend.
Here is what we know right now. Check back with us at weather.com for the latest on this potentially dangerous situation.
Friday night into early Saturday, rain and thunderstorms should be widespread from the southern Plains to the Tennessee Valley.
A few strong to severe thunderstorms may develop in parts of Texas, far southern Oklahoma, southwestern Arkansas and northwestern Louisiana. The Dallas-Fort Worth area is included in this threat.
The primary concern will be large hail, but damaging wind gusts are also possible.
Severe thunderstorms are most likely from eastern Texas into southern Arkansas, northern Louisiana and western Mississippi. Strong tornadoes, damaging winds, hail and locally flooding rainfall are all possible in these areas. The area shaded in purple in the map below shows where the tornado threat is most significant.
Saturday night into early Sunday, severe thunderstorms may sweep ahead of the cold front into Tennessee, eastern Mississippi, southeast Louisiana and western Alabama. Damaging winds and tornadoes are likely.
