 Welcome back. You're with America in the Morning. 100-plus degree temperatures won't be uncommon for some this week. Here's AccuWeather.com meteorologist Matt Rinde. It is going to be hot in portions of the west today, and this is only increasing as high pressure builds into the region throughout the holiday week. Highs this afternoon will soar well into the 100s in the California valleys into the desert southwest. And then later this week, some all-time records could be challenged in these areas.
