More rain could be on the way this week to Southern California

"Parts of the Los Angeles region could see light rain this week as a small chance of thunderstorms brings the possibility of more precipitation following last week's soaking, according to the National Weather Service. There is a 10% chance of rainfall across Los Angeles County on Tuesday night, but that chance of showers drops to as low as 5% going into Wednesday, said Carol Smith, a National Weather Service meteorologist in Onxard. Interior valleys and mountain areas of the Southland are most likely to see rain, she said, with a slight chance of precipitation in the valleys and along the coast."

"There is, however, a slight chance of thunderstorms, particularly over the mountain areas of Ventura and Santa Barbara counties, which could carry over into Los Angeles County near the Grapevine area of the 5 Freeway, Smith said. Those areas could see some isolated dry lightning during the storm. The weather phenomenon occurs when there is dry air near the ground during a thunderstorm and can bring a risk of fire."

""Any part of a thunderstorm has updrafts and downdrafts, and you get these downdrafts with rain if there's enough moisture," Smith said. "But if you don't have very much moisture and really dry air in the lower levels of the atmosphere, it just evaporates.""

Light, midweek precipitation is possible across parts of the Los Angeles region, with a 10% chance of rain Tuesday night and around 5% into Wednesday. Interior valleys and mountain areas of the Southland have the highest likelihood of rain, with smaller chances in valley and coastal areas. Slight thunderstorm potential exists over Ventura and Santa Barbara mountains and could extend into northern Los Angeles County near the Grapevine, bringing isolated dry lightning and virga that can elevate fire risk. Last week’s rainfall temporarily reduced fire threat, and the brief moisture will not change anticipated dry winter conditions.
