More than 39 million people from Louisiana to the mid-Atlantic could experience severe storms. The most significant impacts of these will be the damaging straight line winds from the Gulf Coast across the Carolinas; however, the potential for isolated tornadoes also exists with these storms.
Once these extreme weather conditions have passed, temperatures will drop below freezing overnight with potential for snow across the Appalachians to New England.
The heavy rains caused flash floods that dragged cars into inevitable currents and damaged dozens of homes and buildings.
The tornadoes damaged dozens of homes and businesses in both states.
In Alabama, the community of Eagle Point has seen roofs blown off homes, trees torn from the ground, and downed power lines on the roads.
In Coweta County, Georgia, the town of Newnan was hit by a powerful EF-4 overnight, with residents being warned by sirens 15 to 20 minutes before the tornado hit, residents told CNN.
The storms have killed at least one person in the county, said fire chief Deron Patrick Wilson.
“This stuff is amazing. I think of that kind of stuff when you look in the Midwest, Oklahoma. I think you’re going to see the same kind of damage here,” Wilson said.
Hot and cold air masses causing chaos
Meanwhile, some parts of the country experience large fluctuations in conditions within a short period of time.
A cold Canadian air mass to the west collided with warm air as it moved east, creating winds exceeding hurricane strength in some areas.
A record 81 degrees Fahrenheit was set in Aberdeen, South Dakota on Monday – 33 degrees above normal. After the winds pushed the cold mass, temperatures struggled to reach 39 degrees.
Below-average temperatures erupted across the eastern United States on Wednesday behind a cold front, except for one final warm day in eastern New England.
As this cold front passes, temperatures will also drop dramatically, putting more than 21 million people on frost watches or warnings from the central Mississippi Valley across the Ohio Valley on Thursday mornings. and Friday, when temperatures will be in the upper 20s.
It will even be cold enough for lake effect snow for parts of the Great Lakes: “The core of the cold air (in the atmosphere) will spread over Lake Michigan this evening through early Thursday, which brings us to April. Not too often we discuss lakefront snow in April, but it will be one of those times, albeit brief, ”said the National Weather Service office in Chicago.
Winter weather will also be reviewed across the Appalachian Mountains of West Virginia, the Eastern Great Lakes in parts of New England between Wednesday evening and Thursday evening. Snowfall of 6 to 10 inches is expected in western and upstate New York, with lower totals elsewhere.
Meanwhile, in the western United States, temperatures are above average midweek, but later this week, milder air will move east towards the central United States.
Widespread high temperatures 5 to 15 degrees above average are forecast Friday from the west across the Great Lakes. The northern plains will be the warmest compared to normal, with temperatures up to 30 degrees above average.
Temperatures will warm further for the Easter weekend, with potentially record highs reaching 40 degrees above average for the northern plains. By the end of this weekend, coast-to-coast heat is expected except for parts of the Northwest and Florida.
