Severe weather threat continues as summer heat swelters on both coasts

(NEW YORK) --- Millions of Americans are under severe weather threats as storms and summer heat continue on both coasts.

This severe weather threat will impact parts of the central United States, from Texas to Illinois.

A flood watch is also in effect for parts of eastern Kansas, western Missouri, northeast Oklahoma, and northwest Arkansas until Sunday morning.

A level 3 of 5 "enhanced risk" is in effect for parts of Nebraska, Oklahoma, eastern Kansas and much of western and central Missouri -- including Wichita, Kansas; Kansas City, Missouri; and Springfield, Missouri.

The main threats are damaging winds, large hail and a few tornadoes.

The severe weather threat shifts back to parts of the East Coast with more than 50 million on alert for severe storms on Sunday.

A level 2 of 5 "slight risk" is up from northern North Carolina to upstate New York and includes Raleigh, North Carolina; Washington, D.C.; Philadelphia; New York City; Pittsburgh; and Albany, New York.

The main threats are damaging winds, large hail and lightning.

Heading into next week, the severe weather looks to stall for a couple of days before ramping back up by the middle of the week.

The summer heat and humidity continues in the South, with heat advisories in effect for millions from the Carolinas and Florida out to Arkansas and Oklahoma.

The Northeast will see lower humidity this weekend so the heat will not be as dangerous despite temperatures in the 80s and 90s.

An extreme heat warning is already in place for the Portland, Oregon, area where a life-threatening heat wave is expected Sunday through Tuesday with temps reaching 95 to 100 degrees.

For the West coast, a heat advisory is in place in California's central valley from Redding to Bakersfield with high temps from 100 to 105 possible. Closer to the Bay Area, high temps around 100 are possible for San Jose and Santa Clara.
