 The National Weather Service's Weather Prediction Center is warning a new heat wave in California could bring afternoon highs in the 90s to 100s and overnight lows in the upper 60s to 70s to inland areas. Dylan Flynn is a meteorologist at the NWS's Bay Area office. It's basically going to cover all of our inland areas, and really it's region-wide. So the Central Valley is going to be very warm, lots of 100 degrees throughout the Central Valley area.
