A small chance of showers and thunderstorms will hover over the Southland Monday, the National Weather Service said.
NWS forecasters set the chance of showers and thunderstorms in Los Angeles County at 20 percent Monday afternoon and again Monday evening, although the chance may rise to 25-30 percent in the San Gabriel Mountains and the Antelope Valley, said NWS meteorologist Kathy Hoxsie, adding that precipitation this morning as well is not totally outside the realm of possibility.
The expected precipitation will be the product of monsoonal moisture out of Arizona and Baja California combined with a ridge of high pressure over the Four Corners region of the Western United States and instability in the atmosphere, she said. If any rain materializes, there likely won’t be much of it, said Hoxsie, adding that “we could get less than a 10th of an inch.”
The biggest concern arising from the forecast is the possibility of dry lightning, which can spark wildfires, Hoxsie said. But no fire-related warning had been issued by the NWS as of early Monday morning.
