Flash flooding, severe weather to keep eastern US on alert Tuesday
Torrential downpours will dampen areas from the Midwest to the Northeast, as severe thunderstorms will erupt from New Jersey to Georgia and Mississippi, threatening disruptions and damage.
Thunderstorms and flooding downpours will drench parts of the eastern United States into Tuesday night, disrupting travel and outdoor activities.
Disruptive downpours and thunderstorms will continue to cause travel trouble across parts of the East on Tuesday as humid -- almost tropical air -- adds fuel to an active weather pattern. Flash flooding and severe weather will be hazards into Tuesday evening, AccuWeather meteorologists warn.
Heavy thunderstorms left roads submerged around the nation’s capital on Monday, and the area will once again face locally severe weather and torrential downpours, with the risk of flash flooding.
Thunderstorms could disrupt vacationers' plans along the coast Tuesday
Bursts of rain and thunderstorms will extend from southern Mississippi to New Jersey into Tuesday evening.
Some of the dozens of major cities at risk for severe weather and flash flooding into Tuesday evening include Atlantic City, New Jersey; Norfolk, Virginia; and Raleigh, North Carolina.
Travelers along portions of interstates 10, 75 and 95 are advised to closely monitor the progression of the storms, given that the intense downpours could induce slowdowns and periods of decreased visibility.
Additionally, any beachgoers along the Atlantic and northeast Gulf coasts could deal with disruptions to their outdoor activities as thunderstorms develop and track to the coast. Storms are likely to unfold across a heavily populated corridor to begin with and, given the time of year, vacationers that have flocked to the coast could increase the number of people that can face storms as they grind toward the beaches Tuesday.
A corridor across far northeastern South Carolina to southern New Jersey could face a moderate risk for severe storms, and even a risk for isolated tornadoes.
Calmer, slightly cooler weather in store by midweek
Forecasters say that Wednesday may turn out to be a much nicer day than the start of the week across a large portion of the Eastern U.S.
"As a cold front clears the Northeast coast later Tuesday night, calmer conditions can be expected on Wednesday," AccuWeather Meteorologist La Troy Thornton said. "However, thunderstorms may linger around the coast of the Carolinas and into the Southeast as the front hangs up a bit longer over those areas."
"Moisture may linger over the southeastern corner of the U.S. through the end of the week and into the weekend as the front stalls in the area," AccuWeather Senior Meteorologist Alex Sosnowski said. "Where downpours repeat, flash flooding may occur, especially in parts of Florida."
Temperatures are likely to moderate by midweek across the eastern half of the nation, dropping between 5 and 10 degrees Fahrenheit at the start of the week in some spots.
As a storm system tracks eastward across southeastern Canada, there will be additional chances for rainfall by the latter half of the week, particularly from the Great Lakes to the Northeast.
For much of the Heartland of the U.S. the cooldown will only be temporary, as a massive heat dome will build late in the week and may last for many days.
Severe weather to reload in Upper Midwest
Prior to the heat dome formation, thunderstorms are likely to strengthen to severe levels over part of the Upper Midwest Wednesday.
All modes of severe weather will be possible Wednesday, including the risk of a few tornadoes in parts of Minnesota and northern areas of Wisconsin and Michigan. A large portion of northwestern Ontario is also at risk for severe weather.
The risk of severe weather is likely to progress farther to the southeast on Thursday with impacts in parts of the ower Great Lakes and interior Northeast possible.
