July 4 forecast: Extreme heat, thunderstorms, possible flooding
July 4th will bring extreme heat as well as thunderstorms and a chance of desert flooding, according to the National Weather Service.
"Many areas will continue to see triple-digit temperatures today," the NWS said in an advisory. "Humidity will be a little higher today, and this will make the warm temperatures feel even worse."
Though Southern California has been experiencing a heat wave for several days, the new twist in the weather picture for the Monday holiday is monsoonal moisture.
The NWS said thunderstorms were likely in the mountains and the Antelope Valley but also possible in the L.A. Basin and coastal areas. Flash flooding is possible in mountain areas in the afternoon.
