Millions of people living in the Plains and along the East Coast are again at risk of severe weather and flooding on Tuesday, one day after a possible tornado left significant damage in western New York.

The central and eastern U.S. have been rocked by numerous severe weather reports over the last several days, including deadly storms in Mississippi and Georgia and possible tornadoes in Oklahoma and Virginia.

Deadly storms also tore across portions of Texas, producing 100-mph wind gusts and grapefruit-sized hail.

The FOX Forecast Center said that as a cold front continues to march off to the east, thunderstorms will likely fire up along it as we get into the afternoon hours.

With daytime heating and plentiful moisture due to southerly winds ahead of the cold front, storms that develop may turn severe.

NOAA’s Storm Prediction Center (SPC) highlighted the East Coast from Georgia in the Southeast to Massachusetts in New England under a Level 1 threat on its 5-point severe thunderstorm risk scale.

This includes cities like Savannah in Georgia, Norfolk in Virginia, Philadelphia, New York City and Hartford in Connecticut.

However, it only takes one storm to turn lives upside down and have significant impacts. So, be sure to download the free FOX Weather app and enable notifications to be alerted to severe weather in your area.

The FOX Forecast Center said storms that develop on Tuesday could be capable of producing damaging wind gusts.

Flash flooding is also a concern, with some Flash Flood Warnings already issued earlier Tuesday morning.

“Later (Tuesday), we may see flash flooding because the ground is pretty saturated, and some of these storms may produce an inch, 2 inches of rain, and it will be just enough,” FOX Weather Meteorologist Craig Herrera said.

Since the thunderstorms will be isolated, it could be difficult to pinpoint locations with the higher flood threat on Tuesday.

“It’s really tough to figure out the where, because these are isolated severe storms that will be developing this afternoon, and not everyone will see this type of weather,” FOX Weather Meteorologist Britta Merwin said. 

“But, if we get an isolated severe storm in New York City or Boston, not only do we have an oversaturated environment, but we have an urban environment. And so we just need to watch out for that flood potential,” Merwin warned.

Confidence is also increasing that severe weather and flooding could impact portions of the Desert Southwest, as well as the southern Plains.

A disturbance moving out of the Desert Southwest is approaching the region on Tuesday, and that will provide an added boost to thunderstorm development.

The SPC has placed portions of West Texas and southeastern New Mexico in a Level 2 out of 5 severe weather threat on Tuesday.

The FOX Forecast Center said that with winds remaining light throughout most levels of the atmosphere, storms will be slow-moving and could produce high rain totals and an increasing flood potential.

NOAA’s Weather Prediction Center (WPC) has placed a large portion of the region in a Level 2 out of 4 flash flood threat on Wednesday and Thursday, with the threat shifting to the east into the Ark-La-Tex region by Thursday.

The FOX Forecast Center said that the San Antonio and Austin areas in Texas and points west into Fort Stockton and El Paso are under an exceptional drought, and flash flooding could be heightened due to water runoff from torrential rain rates.

The ground there is extremely dry, and water won’t have time to be absorbed fast enough, which is why there are concerns of flash flooding.
