Severe weather revealed in the southern United States and hurricane threat to continue until Monday – AccuWeather.com/ar/
AccuWeather meteorologists say the severe weather threat that began this weekend will continue across the Southern states through Monday evening. Rounds of storms will blow east along the stalled frontal boundary, setting the stage for severe weather from Texas to the Carolinas.
The first round of severe weather rolled through Saturday afternoon into Saturday evening, bringing hail and heavy rain to Central Texas. Hail up to the size of golf balls occurred.
As of mid-afternoon Sunday, hailstones the size of baseballs were reported in Northeast Texas.
Waves pumping moisture into the area will create a steady stream of rain for some that could ignite the risk of flooding. Storms could drop several inches of rain as rounds of heavy rain and thunderstorms roll across the South, raising river and stream levels and halting travel in the region.
Locations from northeast Texas into Kentucky, southwest Virginia and central Virginia could collect 1-2 inches of rain through Monday, while a wide corridor from the Texas-Louisiana border through the Smoky Mountains could get 2-4 inches of rain with AccuWeather StormMax™ Domestic 10-Inch.
Travelers along Interstates 10, 20, 35, 55 and 75 may experience slowdowns as thunderstorms move through the South. Even air travelers with destinations and departures across the Southeast could face delays or cancellations until early next week as an active weather pattern takes hold of the region.

“Flights are likely to be delayed at airports like Atlanta Hartsfield-Jackson International Airport, the world’s busiest, as heavy rain and thunderstorms occur on Monday,” AccuWeather Meteorologist Alex Da Silva explained.
Through Sunday night, the greatest risk for severe storms will shift eastward across northern and central Louisiana, central Mississippi and central Alabama. The main risks of hail, heavy rain and gusty winds will remain a concern as storms move into new areas. However, this risk also includes the possibility of a few tornadoes.

Cities like New Orleans. Jackson, Mississippi; Birmingham, Alabama, is expected to see rounds of strong to severe storms through Sunday night, as moist air from the Gulf collides with tracking energy off the southern Plains.
People and officials in the path of the storms are encouraged to stay informed of severe weather bulletins as they are issued, even if some may be distracted by the NFL Championship Game. Some storms, including the threat of tornadoes, will occur well after dark when it will be difficult to see approaching violent weather.
As of mid-afternoon Sunday, thunderstorms rapidly increased in intensity from north of Houston to Greenville, Mississippi. This batch of storms will be the primary focus of severe weather as it moves east through Sunday night.
Storms could pack sustained winds of 60-70 mph throughout the day and night hours on Sunday with an AccuWeather Local StormMax™ of 80 mph.
“The storm is expected to turn toward the southeast and become more organized by Monday, then it will begin to curve toward the northeast and make its way into the mid-Atlantic states on Monday evening,” DaSilva said.
Isolated isolated storms within severe thunderstorms will remain a risk through Monday as storms move across the Southeast and eventually reach the coast.
As a low pressure area advances across the Tennessee Valley and into the northeast early next week, cold conditions along the northwest side of the storm will cause rain to turn to snow.
After several days of April-like temperatures and dry weather over the past week, the winter impacts expected to arrive in the Ohio Valley and Northeast could be a harsh return to reality. Temperatures are expected to return to normal values in mid-February before the storm arrives early next week.
The storm is expected to cover much of the Northeast with a half-foot to a foot of snow and major travel problems Monday night into Tuesday.
Meanwhile, locations across the South Central and Southeast will trade a windy weekend pattern for calmer, drier conditions as a high pressure area reaches the south early to mid-week.
