 Most of the country is expected to be suffering from scorching temperatures for the 4th of July. Record temps are expected nationwide, with humidity in the south making areas such as New Orleans feel like it's 120 degrees there. Parts of Arizona, California, and Nevada could see the temperature hit nearly 115 degrees some days, with both Las Vegas and Phoenix expected to hit that number around the holiday. Heat advisories are in effect for much of the East Coast as well. I'm Chris Coraggio.
