 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. The southern plains will also be largely dry with sunshine and a hot afternoon. Highs will be well into the 90s and 100s. And then heading into the northern plains, we have a storm system moving out of the northern Rockies into the region, which will trigger several showers and thunderstorms through the Dakotas into Minnesota and Nebraska eastward to Iowa.
