Severe Weather Hits the Eastern U.S.

On Tuesday, a stretch of severe weather continued its eastward journey, bringing an unusually hectic day across much of the eastern United States.

With severe storms comes the risk of tornadoes, wind damage, and large hail, while heavy rainfall raises concerns about widespread flash flooding, affecting over 116 million individuals.

This multi-day threat kicked off Monday, with multiple tornado warnings, large hail, and damaging winds impacting parts of the upper Midwest through the afternoon and evening.

Iowa experienced some of the strongest wind gusts, clocking in at 80 mph in Sheffield, while Watson, Michigan, reported an impressive three inches of hail.

As the storms moved east on Tuesday, conditions were reminiscent of Saturday’s severe weather, which caused significant storms and flash flooding in various areas.

Currently, a highly active weather pattern could lead to severe storms and flash flooding stretching from the Midwest all the way to the Northeast.

As of Tuesday, the severe weather threat has been elevated to Level 3 on a five-point scale for 35 million people, with an additional 50 million upgraded to Level 2 threat levels.

The first storm is anticipated to develop in the morning, affecting regions from eastern Virginia to the tri-state area and southern New England.

This initial storm is expected to be less intense but could still produce gusty winds and heavy rain.

There’s a chance of flash flooding, particularly in urban centers, which might disrupt the morning commute.

“Significant flash flooding is a real concern, with scenes of submerged roads and flooded subways likely,” the FOX Prediction Center noted.

Ultimately, this first wave will pave the way for the main storm later in the day.

Severe Thunderstorm Threat

A primary line of thunderstorms is expected to develop by mid-morning along a front stretching from the upper Ohio Valley to western New York.

As these storms move eastward throughout the afternoon, they’ll begin to intensify, reaching the I-95 corridor during or just after the evening rush hour.

The main threats include strong winds that could cause widespread damage, toppling trees, along with the possibility of tornadoes.

The FOX Prediction Center stated, “The area with the highest likelihood for tornadoes stretches from western New York to eastern Pennsylvania.”

Hail is also a concern, particularly in the central Ohio Valley, but most severe wind damage is expected across the Mid-Atlantic region.

Flash Flood Risk

There is heightened awareness regarding the potential for flash flooding.

The situation on Tuesday closely mirrors last Saturday’s storms, which led to extensive flooding in New York City, New Jersey, and western Pennsylvania.

With atmospheric moisture in play, rainfall could reach 2.5 inches per hour—almost half of the average monthly rainfall for July.

The FOX Forecast Center emphasized the importance of noting that this heavy downpour will fall on ground already saturated from Saturday’s rainfall.

The storm’s primary wave is anticipated to hit the I-95 Megalopolis between 6 p.m. and 8 p.m., with offshore movement expected by midnight.

This same storm could also bring heavy rain along I-95 from the Delmarva Peninsula to southern New England.
