Dangerous heat spreads into the Northeast next week
As the heat dome spreads east, it'll cast a wide net over more than half of the country, causing potentially life-threatening temperatures.
This weekend the heat will spread across the Midwest and into the Great Lakes, where high temperatures will surge 10-20 degrees above average.
By Sunday, more than 200 million Americans will see temperatures at or above 90 degrees with various heat alerts spanning from Colorado to Maine. High humidity with dew points reaching into the 70s if not near 80 degrees will make temperatures feel well over 100 degrees in cities like Chicago, Louisville, Cleveland, Nashville and Raleigh, according to the FOX Forecast Center.
The high humidity will also make for warm nights, offering very little relief from the extreme daytime temps.
