Southern California is likely to get Halloween rain this year, with the best chance arriving Saturday evening, Oct. 31, and continuing into Sunday morning, according to the National Weather Service. Los Angeles, San Diego and much of the South Coast are in the storm’s path, while the Bay Area should stay mostly dry until late at night. If showers fall Saturday, it would be the first rainy Halloween in the Los Angeles area since 2014.
The first chance of light showers arrives Friday, though forecasters put those odds at only about 20%. Rain should clear quickly Sunday morning, with sunshine possible by Sunday afternoon.

Other outlets show just how wide the range still is. ABC7 says up to a half inch could fall in Los Angeles and Orange counties on Halloween, with up to three quarters of an inch possible in the valleys and Inland Empire. The San Francisco Chronicle puts the South Coast range anywhere from a half inch to 2 inches between Saturday afternoon and Sunday evening…
