Thunderstorms stretching from southwest Missouri to northeastern Pennsylvania were forecast to drop as much as 5 inches of rain Monday, putting a damper on Fourth of July celebrations, NBC News reported.
Locally severe storms are possible from the central Appalachian Mountains into the Ohio Valley and the mid-South, the National Weather Service said. Flash floods, damaging wind gusts and hail are possible, it said.
The center of the system may bring 3 to 5 inches of rain, and will stretch across the northern half of Illinois on Monday, with bands of rain up to 3 inches from Springfield, Missouri, to the middle parts of Illinois, Indiana and Ohio into Pennsylvania.
And more than an inch of rain is expected across pretty much the entire eastern half of the country, except for most of South Carolina and north of New York, forecasters said.
