Forecasters are putting out an early alert for the potential for severe thunderstorms to march across the southern United States next week.
While the exact severity and coverage of the thunderstorms will need to be ironed out in the coming days, AccuWeather meteorologists say that the upcoming pattern next week bears close monitoring, specifically for residents from Texas to the Deep South.
A strong jet stream will divide cold air to the northwest and warm, moist air to the southeast over the center of the nation during the first days of March.
"Whenever you get a big temperature difference or different air masses in close proximity to each other, you get a storm and we're going to see that Tuesday into Wednesday," AccuWeather Chief Broadcast Meteorologist Bernie Rayno said.
This storm is likely to renew flash and river flooding concerns from the lower Mississippi Valley to the Tennessee and Ohio valleys as it unleashes widespread heavy rainfall. But AccuWeather meteorologists are concerned that flooding will not be the only hazard.

"There's at least a chance, and I believe at this point it's a good chance, for severe weather late Tuesday into Wednesday from east Texas toward Louisiana, Mississippi and Alabama," Rayno said.
Whether just a few severe thunderstorms erupt or a full-blown outbreak of violent weather occurs will depend on a variety of factors in the atmosphere which will become clearer over the coming days. These factors include, but are not limited to, extent of rain and cloud cover, thunderstorm timing and strength and degree of turning of the winds a few thousand feet above the ground.
If all of the necessary ingredients come together, isolated tornadoes could accompany the damaging winds, frequent lightning strikes and hail that are common in severe thunderstorms. Flash flooding will also be a major concern given how saturated the ground is across the region.
Regardless of the severity of the thunderstorms, motorists across the South are likely to face times of slow travel due to reduced visibility and ponding of water on the roadways. These hazards can be encountered on long stretches of interstates 10, 20, 30, 40, 49, 55, 59, 75 and 85.
Airline delays could hit the major hubs of Dallas, Houston and Atlanta during the middle days of next week.
AccuWeather meteorologists are actively monitoring the situation and will continue to provide further details on the timing, extent and intensity of next week's thunderstorms in the days ahead.
