A swath of heavy rain is expected to jeopardize Fourth of July plans across the mid-Atlantic putting barbecues and fireworks shows at risk.
An area of low pressure will ride along a stalled front extending from the Ohio Valley to the Delmarva Peninsula and will cause all sorts of trouble for those with outdoor plans.
"The heaviest rain and the best chance for thunder looks to impact southern parts of the Ohio Valley and the Tennessee Valley into the Delmarva," AccuWeather Meteorologist Becky Elliott said.
Cities at risk include Louisville, Kentucky, Cincinnati, Charleston, West Virginia, and Washington, D.C.
Rainfall on the magnitude of several inches will soak an area along the front and may bring flooding.
West Virginia, which was devastated by flooding recently, will again be in the zone for dangerous flooding.
Outdoor plans such as barbecues, picnics and fireworks shows will all be at risk of being washed out.
"Residents across the mid-Atlantic and Ohio Valley that plan on having outdoor barbecues will want to have an indoor backup plan," Elliott suggested.
Large fireworks displays, such as the Capitol Fourth Fireworks show in Washington, D.C., will be at risk for being postponed due to heavy rain. In many cases, Tuesday rain dates may need to be taken advantage of.
Those planning on seeing baseball games in Washington, D.C., or Philadelphia on the Fourth of July may be disappointed by delays or even cancellations.
Farther south across Virginia and North Carolina, thunderstorms will put plans at risk, but the activity will be more scattered. However, some of the thunderstorms could be strong with gusty winds and flooding downpours.
People heading to the beach from southern New Jersey to the Outer Banks may face afternoon thunderstorms.
A sharp line on the northern side of the front will exist between where it rains and where it stays dry. One small shift of the front could result in a soaked holiday party.

While unsettled weather is focused on the mid-Atlantic on Monday, high pressure will continue to dominate the Northeast which will bring spectacular weather for the holiday.
"Much of the rain and storms look to be suppressed south of the Mason-Dixon Line, so the majority of the Northeast will remain dry," Elliott said.
Temperatures will remain seasonable under sunshine-filled skies and the summertime humidity will be lacking, which will aid in comfortability.
However, those who do plan to spend most of their day outside, whether it is at the beach or in the backyard, are urged to put on sunscreen.
Fireworks shows in New York City, Boston and everywhere else in the Northeast should not have any weather-related issues on Monday evening. It will be great day for baseball games as well.
