Intense humidity, triple-digit heat move into Southern California forecast

LOS ANGELES (KABC) -- Humid and muggy conditions will linger across Southern California as showers move out of the region and temperatures spike.

Wednesday is expected to be the hottest day of the heat wave.

A slight cooldown begins on Thursday, with a much more significant drop in temperatures expected by the weekend, when the sea breeze returns.
