Record-breaking heat continues in Riverside County
RIVERSIDE — Temperatures across Riverside County will drop a degree or two today following a second straight day of record-breaking heat, but with the mercury still hitting triple digits, the slightly cooler weather “won’t be very noticeable,” the National Weather Service said.
An excessive heat warning for most of the county is still in effect through Friday night, while the mountains are under a less-serious heat advisory during that same period.

High temperatures in the desert included 116 degrees in Palm Springs, 114 degrees in Thermal and 113 degrees in Indio.

High temperatures today will be 105 to 110 in Riverside and Lake Elsinore, 92 to 99 in the mountains, 109 to 114 in the San Gorgonio Pass and 109 to 114 in the Coachella Valley.
