Temperatures will soar into the 80s along the coast and the 90s — and possibly 100 — across inland valleys and foothills on Friday and Saturday as a high pressure system brings heat to Southern California.
And it’s going to be dry. Very, very dry.
“The relative humidity in places like El Cajon and Escondido could fall to 15 percent,” said Alex Tardy, a forecaster at the National Weather Service. “The humidity also will be low at the coast, until the sea breeze kicks in.”
San Diego has an average high of 74 this time of year. Tardy says San Diego International Airport could reach 85, and perhaps higher. Areas like Ramona, Escondido and Alpine are expected to reach 94 to 95 degrees on Friday, and the upper 90s on Saturday, with a few 100 readings possible.
Daytime highs will decline sharply on Sunday.
