To the north, hail has reached the size of a tenth of a penny in the Dallas-Fort Worth area.
Texas sees the onset of dangerous and violent storms that are expected to hit parts of the Southeast and Ohio Valley this weekend.
This powerful system will create the potential for potentially lethal winds, strong tornadoes and large hail.
And Sunday, an increased risk (level 3 out of 5) extends from Atlanta to Cleveland.
Strong storms from Texas to Mississippi
The first severe thunderstorms were expected late Saturday afternoon at noon in eastern Texas, Louisiana, southern Arkansas and eastern Mississippi. Cities such as Shreveport (Louisiana) and Jackson (Mississippi) could be affected.
Chad Myers, a meteorologist at CNN, said that the hot air present during the afternoon would reinforce the instability of the atmosphere, giving more energy to storms and to helping them to grow.
He said that the threat of severe weather is greatest in these times.
The storms most capable of producing tornadoes and large hail will be the individual rotating cells that will form in front of a larger thunderstorm complex throughout the afternoon.
Tornadoes possible during the night in Alabama
By the end of Saturday, the storms should be organized to form a line as they cross the western border of the Mississippi.
The system will begin to spend the night in Alabama and should reach Georgia on Sunday morning.
The energy released by the hot afternoon temperatures will decrease, but the risk of tornado will not be over.
"The storm is so intense that tornadoes are still possible after dark," said Myers.
Tornadoes at this time can be particularly dangerous because they are hard to see and people are less likely to receive warnings when they are asleep.
Georgia, Southern Appalachians and Ohio Valley
The biggest risk of extreme weather is expected Saturday, but the Sunday potential is still considerable.
The Storm Prediction Center has generated increased risk over a vast area ranging from eastern Alabama through the southern Appalachians and into the Ohio Valley. The main line of storms will begin to enter this area late Sunday morning and walk east on Sunday afternoon. The center said it's expecting the threat of severe weather to increase throughout the afternoon.
"Strong winds appear to be the biggest threat on Sunday, but tornadoes will also be possible," said CNN weatherman Dave Hennen.
The risk will slowly decrease as the system begins to weaken on Sunday night.
The Masters tournament could have an exciting final
The storms are expected to move in the Augusta area during the afternoon and evening, which could affect the timing of some players finishing their rounds.
The threat of a tornado will be less important, but strong winds could still present dangerous conditions.
Whatever the case may be, this could lead to a late end and an interesting end to the four-day tournament.
