Scorching heat, muggy conditions and the possibility of thunderstorms will return to Southern California, making this week uncomfortable and sticky. With triple-digit temperatures on the forecast for much of the interior valleys, mountains and deserts, the National Weather Service issued an excessive heat warning Monday. “High temperatures will [be] quite high today with some heat risk issues today and Tuesday,” meteorologist Curt Kaplan said in a weather statement. “Overall, expect humid and hot conditions to continue through much of the week. If the heat wasn’t enough to activate sweat glands, forecasters says, a monsoonal flow pattern will bring humid conditions and a slight chance of thunderstorms by Tuesday.
