Violent thunderstorms, capable of spawning tornadoes, will sweep eastward across the Deep South tonight through Tuesday evening.
This severe weather episode that AccuWeather.com Senior Meteorologist Jim Andrews warned about over the past weekend is now unfolding.
The first round of violent thunderstorms are threatening Louisiana and Mississippi tonight.
There has already been damage reported across parts of Louisiana. A tornado touched down around 3:13 PM local time near Atlanta, La., and destroyed 3 homes. The tornado produced a damage path 100 yards wide and knocked down numerous trees and power lines. Similar damage can be expected with the strongest thunderstorms through tonight.
It is not out of the question that the threat of locally severe thunderstorms continues into Tuesday night and approaches the southern Atlantic Seaboard.
The strongest thunderstorms into Tuesday will be capable of unleashing damaging wind gusts. Several tornadoes may touch down and cause greater destruction.
Residents should closely monitor local media outlets and seek shelter immediately if a storm-related warning is issued.
Motorists should also heed these warnings. Remember, a vehicle is one of the worst places to be during a tornado. Stretches of Interstates 10, 20, 55, 65 and 75 will lie in the path of the violent thunderstorms.
The presence of ample moisture from the Gulf of Mexico will allow many of the thunderstorms to unleash downpours. While the drought-stricken South is in need of heavy rain, localized flooding problems may ensue.
The flood danger will not be limited to the areas being threatened by severe weather. Torrential rainfall is set to invade parts of the Midwest, spine of the Appalachians and Northeast tonight into Wednesday.
The storm system triggering the upcoming severe weather and flooding rain also has a wintry side that will endanger motorists across the Upper Midwest.
A storm will bring snow and ice that will lead to slippery travel along a 1,500-mile swath from northern Arkansas and Georgia to Maine early next week.
The coldest air of the winter will plunge southward across much of the eastern United States and will feature single-digit and sub-zero temperatures in the Northeast during Valentine's Day weekend.
A blast of arctic air will be accompanied by flurries and even a localized wall of snow in some communities in the Northeast and parts of the Midwest at the start of the Valentine's Day weekend.
The next windstorm to target Europe will narrowly miss the United Kingdom on Saturday before a cold snap settles in for Valentine’s Day and Monday.
