A powerful storm is moving across the eastern U.S., bringing heavy rain, flash floods, and severe thunderstorms to many areas. According to AccuWeather, the bad weather will continue through early Friday, but cooler and less humid air from Canada will bring relief over the weekend.
Flash Flood Warnings for Northeast & Mid-Atlantic
More than 40 million people are at risk of flash floods. A combination of a cold front and a jet stream disturbance is expected to dump 2 to 4 inches of rain across several states—including:
- Eastern Pennsylvania
- Maryland
- Northern Virginia
- Delaware
- New York City
- Connecticut
- Rhode Island
- Parts of Massachusetts
Some places may even get up to 8 inches of rain, which could overwhelm drainage systems, flood roads, and even subway stations—especially in cities like New York.
 Severe Storms from Pennsylvania to South Carolina
Severe thunderstorms are also expected from southern Pennsylvania all the way down to South Carolina. These storms may bring:
- Strong wind gusts
- Heavy rain
- Localized flash flooding
The heaviest rain will likely hit the northern part of this region Thursday evening. Some storms may continue south into Georgia by Friday.
 Rain Moves from Midwest to Northeast
The storm started Wednesday night in Indiana, Ohio, and upstate New York, and is now spreading east. This will add more rain to areas already soaked from previous storms.
 Relief Coming This Weekend
After the storm moves out, cool and dry air from Canada will replace the hot, sticky air across the Northeast and Mid-Atlantic. Expect:
- Daytime highs in the 60s to low 80s
- Nighttime lows in the 40s to 60s, and even 30s in mountain areas
Cities like Philadelphia, Baltimore, and Washington, D.C. will finally feel some cooler air.

 Coastal Flooding Risk
Strong northeast winds will blow along the coast due to the difference in pressure between the Canadian high and a storm near the Southeast. This may cause:
- Rough waves
- Dangerous rip currents
- Minor flooding during high tides in places like Cape Cod, Atlantic City, and Ocean City
Stay updated with local forecasts and follow safety instructions if you’re in an affected area.
