How much rain has Southern California really received this year? To answer these questions, we have worked with the Scripps Institute of Oceanography in recent years to put our precipitation in context.
This graph above reflects rainfall data from 20 rain gauges around the Los Angeles Basin. These gauges have detailed records stretching back decades and give a picture of how much rain is falling across the region. This year’s rainfall is reflected in the the red line; the blue line represents the median totals.
The chart tracks rain according to the "water year," which runs from October 1 through September 30.
We have had quite the week of weather across SW CA. Rainfall was at record levels for several locations. It was also very chilly yesterday with a number of record low max temps across the region. Here is a summary of the records across the region. #LARain #LAWeather #SoCal #cawx pic.twitter.com/bGqHlsL4YX

So where do things stand?
Forecasters say we're down to a few light showers across the Southland today and snowfall is expected in the mountains through tonight.
Ryan Kittell with the National Weather Service has your weekend overview:
"We are expecting maybe some clouds to greet people in the morning on Saturday, but definitely warmer conditions from what we saw yesterday {THURS} and today {FRI}. And then by Sunday, maybe a little bit more of a gloomier — more like June gloom type — weather with maybe some drizzle in the area."
Meantime, a winter storm advisory remains in effect for L.A., Riverside and San Bernardino county mountains through 8 p.m. tonight.
