Severe storms expected from the Plains to the Northeast

Heat is the main concern in the West and South.

Strong storms brought more than 5 inches of rain and 70 mph wind gusts in Baltimore on Tuesday, while Nebraska saw a gust over 80 mph.

More severe weather is expected Wednesday as two cold fronts move through the eastern half of the U.S.

The second cold front will bring severe storms from the Great Lakes into the Plains. The biggest threat will be damaging winds and large hail, while an isolated tornado cannot be ruled out. Flash flooding could also be a threat for parts of Kansas and Missouri.

Scorching summer heat

The heat is on from Pacific Northwest and into the Deep South.

Nine states from Washington to Mississippi are under heat advisories on Wednesday.

In the Deep South, the humidity will make it feel like it's 110 degrees.

Also, there is a high fire danger from California to Nevada and into the Pacific Northwest. Fires could spread easily in these areas with gusty winds, dry conditions and hot temperatures.
