Tornadoes, damaging wind to accompany severe storms across Mississippi Valley on Groundhog Day

A significant storm will be taking shape late this weekend into early next week and those living in the Mississippi Valley and Deep South will want to take notice.

"A multi-day severe weather event will unfold to start the upcoming week as a warm and moist air mass located along the Gulf Coast collides with a strong cold front moving east," said AccuWeather Meteorologist Becky Elliott.

The threat for thunderstorms will increase Monday and Tuesday with the potential for some of them to turn severe in over ten states, spanning from southern Illinois and Indiana to Louisiana, Mississippi, and Alabama.

The strongest thunderstorms will have the potential to spin up a few tornadoes as well as damaging wind gusts in excess of 60 mph that could topple trees and bring down power lines.

Those living in the threat area should not be surprised if power outages occur during these thunderstorms and will want to be fully prepared if such a situation were to occur.

Making sure batteries are charged and flashlights are in working order is a good first step when preparing for severe weather.

Strong thunderstorms will begin to initialize Monday night across eastern Texas and Oklahoma and will push eastward into Arkansas and Louisiana as the night progresses. The severe threat will be more isolated during this time.

The threat will push farther east Tuesday, putting St. Louis, Little Rock, and New Orleans in the risk area.

"The main round of severe weather will come on Tuesday, with damaging winds, heavy rain, and isolated tornadoes all expected threats," warned Elliott.

The main threat will likely come with a squall line which will sweep across this area packing damaging winds and a burst of very heavy rainfall. There can be quick spin-ups of tornadoes within this line of thunderstorms.

The burst of rain in a short amount of time could lead to some street flooding, forcing detours on motorists and extended travel time. Those traveling on Interstates 10, 20, 40, 55, 59 will have to battle blinding downpours.

The line of storms will push eastward through Tuesday night, turning into a mainly damaging wind threat, although an isolated tornado will still not be able to be ruled out. Louisville, Kentucky; Nashville, Tennessee; Birmingham, Alabama; and Mobile, Alabama will be in the path during this time for these storms.

Despite the absence of thunderstorms in the Northeast, very strong winds will be in place aloft which could mix and be brought down to the surface. Loose items will be blown around and sporadic power outages are possible.

While the bulk of the energy with this storm system will zip north into Canada Wednesday, there will still be a threat for flooding downpours and strong wind gusts with storms across the Southeast.

Cities in the Northeast from Boston to Washington, D.C. will experience a mild but cloudy day with plenty of rain expected.

While this storm spawns severe weather in some states, it will also be responsible for bringing a blizzard to others on the northern and western side of it. This storm system will be responsible for sending an extended period of cold air into much of the northern and eastern United States for the end of the week and weekend.
