Hot pattern to swell over much of Lower 48 this weekend.
An early summer heat wave will bring temperatures about 10 degrees above normal for much of the U.S.
'Summer is here, and the atmosphere knows it. A sprawling dome of heat will park over the United States next week, bringing highs topping 90 degrees to 130 million Americans and triple-digit temperatures to some.
It will feel even hotter because of soaring humidity in the East, while the same dome of heat saps the West of moisture and bolsters late-season wildfire concerns. The core of the heat could eventually become centered over the Great Lakes as the massive ridge of high pressure spans coast to coast.
The first signs of the fledgling heat dome were already emerging in the West, where strong high pressure was bringing temperatures over 100 to the Central Valley of California and interior Washington State earlier in the week. Heat advisories blanketed the Columbia River Valley region, and the harshest temperatures have since expanded east.
Bismarck, N.D., is expected to hit 101 degrees Friday, with widespread hundred-degree readings across the Dakotas. That could be a new daily record for Bismarck, beating out the 95 degrees observed in 1988. It will probably nab a record Saturday, too, with a projected high of 97 degrees.'>>>
