Severe weather to threaten areas from Philadelphia to Charlotte
Following two days of severe weather and tornadoes that turned deadly in the central United States, the risk of powerful thunderstorms will shift to areas east of the Appalachians, stretching from southeastern New York to the Carolinas on Thursday, AccuWeather meteorologists warn.
Even though the threat of tornadoes will be much lower on Thursday in the East compared to prior days in the Midwest, the storms will still pack a punch, posing some threat to lives and property in the region and likely hindering outdoor plans. Significant travel disruptions are also anticipated.
"Just enough warm air and moisture will be present ahead of an advancing cold front to trigger heavy, gusty and locally severe thunderstorms," AccuWeather Meteorologist Alyssa Smithmyer said. "The main threats from the storms on Thursday will be from wind and hail."

Some locally severe storms arrived in the central and southern Appalachians Wednesday night. Some locations experienced vivid lightning, thunder and damaging wind gusts from central New York and western and central Pennsylvania to West Virginia, western Virginia, the eastern parts of Kentucky and Tennessee and western North Carolina.
As temperatures climb through Thursday afternoon and the cold front lifts the warm, moist air over the region, some ongoing thunderstorms will regain intensity. New thunderstorms will also erupt from southeastern New York to the central and western portions of North and South Carolina.
"Thunderstorms are expected to erupt and re-strengthen along and east of the Interstate 81 corridor from Pennsylvania to Virginia before reaching the I-95 corridor in the early evening at peak intensity," AccuWeather Senior Meteorologist Brett Anderson said.

Some of the major metro areas in the mid-Atlantic that could experience severe weather into Thursday evening include Philadelphia and Washington, D.C. Farther south, Richmond, Virginia, Charlotte and Raleigh, North Carolina, as well as Greenville and Columbia, South Carolina, will be in the path of severe storms.
"There is the potential for localized wind damage and power outages due to falling trees and crashing large tree limbs caused by the storms," Anderson said.
Wind gusts between 40 and 50 mph will be common in thunderstorms. However, the strongest storms will bring gusts between 50 and 60 mph, with an AccuWeather Local StormMax™ gust of 70 mph possible.
"Rainfall will be intense during any storm, which will lead to poor visibility and ponding on area streets and highways for motorists," Anderson said.
Severe weather is no longer expected in Augusta, Georgia, where the first round of the 2023 Masters Tournament is scheduled, according to AccuWeather forecasters. However, spectators and golfers may be at risk of lightning strikes and the effects of sudden wind gusts and bursts of heavy rain.
Airline passengers should expect flight delays and cancellations as storms approach and pass through regional and major airport hubs. Officials may issue ground stops at some locations, preventing aircraft from leaving an airport directly within the path of the storms or if a flight is scheduled to a location that may be hit with severe weather.

On Friday, a push of cooler and drier air will end the severe weather threat in the mid-Atlantic region.
Farther to the south, the front triggering the stormy weather will stall in a zone where copious amounts of moisture will continue flowing. Repeated rounds of heavy rain will raise the risk of flash, urban and small stream flooding from Texas to the Carolinas into this weekend.
It has been an incredibly active start to the severe weather season thus far in 2023, with 422 preliminary tornado reports through the first few days of April.
