The first batch of rain has moved out of the area. This was just the appetizer ahead of the main storm system.
I've posted a satellite loop below, which shows low level moisture. You can see a moisture plume that goes from the tropics all the way into our area. You can feel the humidity when you step outside. This should enhance the rainfall potential.
Rain will begin to move into the area around 1 PM, though the heaviest will be between 2 to 6 PM, with embedded downpours.
The rain will become more scattered tonight, then isolated showers are possible on Christmas.
Another round of showers will arrive Friday late morning into the afternoon. This round won't be as intense, but will bring a little more rain to the area.
I've posted the computer projection for rainfall below. You can see that the lion's share of rain will be in the mountains around Los Angeles. For San Diego County, coastal areas will see 1 to 2" with mountains seeing 2 to 4".
Snow levels will remain high during this event, so I'm not expecting snow in San Diego mountains.
