(CNN)Saturday will be the third time this week that some Southern states are facing the possibility of severe weather.
The weekend forecast calls for damaging winds, hail and even tornadoes to some of the same locations just hit by tornadoes and damaging winds less than 48 hours ago.”All hazards are possible including large hail, damaging wind, and tornadoes,” the National Weather Service’s Storm Prediction Center cautions. “Potential for a strong tornado exists from eastern Arkansas into western Tennessee.”
A warm front will lift north early Saturday, bringing storms. A few could be severe, with hail in the morning, hail & wind in the afternoon. A greater severe risk appears likely Saturday night, ahead of a cold front. Wind, hail and a few tornadoes will be possible. pic.twitter.com/2GjfG1uq6W
— NWS Memphis (@NWSMemphis) March 26, 2021 Severe storms and tornadoes hit the South, killing at least 6 and leaving heavy destructionMississippi, Alabama and Georgia also have the potential for severe weather this weekend, less than two days after multiple tornadoes were reported to have touched down in those states. This could make cleanup efforts more difficult as new storms threaten to hit the same locations.”The main takeaway is Saturday could be a busy day across the region with flooding and severe weather being possible,” according to the weather service’s office in Memphis.

There is a lower a risk from central Illinois through northern Texas and northern Georgia on Saturday into Saturday night.Here's why the US has more tornadoes than any other countryWhile a few rounds of showers and thunderstorms are expected during the day, the severe weather threat will be most significant on Saturday evening and overnight into Sunday.Current model guidance is suggesting a line of thunderstorms Saturday night, spanning from the Ohio River Valley to near the Gulf Coast. Wind and hail will be the main threats, but tornadoes are expected with some storms, especially in the mid-South.”Just like the last few events these warm fronts have been pretty efficient rain producers and this particular one will be no exception,” said the weather service’s Memphis office. The potential for flash flooding on Saturday stretches from the Arkansas-Louisiana-Texas region up through West Virginia due to the possible risk of excessive rainfall. The weather service’s Weather Prediction Center says that there will likely be scattered flash flooding centered across the Tennessee Valley, as the latest soil moisture analysis shows that “much of the risk area is above the 98th percentile (extremely saturated).”Sunday storms shift eastBy Sunday, the storm system is forecast to track farther east closer to the Atlantic Coast. Nearly 60 million people are at risk for severe storms from Delaware down to Georgia.”Damaging wind will be the main threats, but a few tornadoes and some hail will also be possible before the front moves offshore during the evening,” said the Storm Prediction Center about Sunday’s threat.The forecast calls for a “slight risk” — level 2 out of 5 — for severe storms in cities like Washington, DC, Baltimore, Richmond, Charlotte and Atlanta.Temperatures will be in the 70s and 80s and this warm, moderately moist environment helps fuel thunderstorms. Another concern for Sunday is flooding. Several states have had multiple days of rain this past week, leading to already saturated ground. Through Monday widespread rainfall of 2-4 inches is expected, with locally higher amounts possible across the mid-South.The highest chance for flooding this weekend exists in Alabama, Arkansas, Georgia, Mississippi and Tennessee.Another area of concern is along the Gulf Coast. Since Tuesday, areas of Louisiana and Mississippi received more than 8 inches of rain, with some pockets of 10-14 inches across coastal parishes south of metro New Orleans. With the ground already very saturated, it will not take much rain on Sunday to trigger flooding.
