A slow-moving cold front will track through New England on Friday, bringing unsettled weather to the region.
The front, which will extend over the Northeast and into the Ohio River Valley, could produce large hail, damaging winds and periods of heavy rain.
Meanwhile, blistering temperatures are expected to rack the Central region. The Northern Plains will approach highs near 90, and the South will see another day in the 100s. Heat advisories will remain in effect through Friday evening across the Mississippi River Valley.
Scattered showers and thunderstorms will extend over the Southern Rockies, while showers will drizzle over parts of the Central Rockies.
The West Coast will be warm and dry, with scattered clouds in the Pacific Northwest and mostly sunny skies in California.
Temperatures in the Lower 48 states Thursday ranged from 36 degrees at Yellowstone, Wyo., to 107 degrees at New Braunfels, Texas.
