(WEATHER CHANNEL) Warnings for extreme heat are posted into the weekend across parts of Arizona, California and Nevada as a large, hot dome of high pressure builds over the region.

Temperatures will soar well into the 110s and even 120s in the days ahead. One location could even approach 130 degrees!

Hot temperatures will also spread throughout the valleys of the Great Basin and Northwest, but not to the levels we will see in the Southwest.
