After light rain fell overnight in many areas, the system produced more rain starting in the early afternoon.
But the storm will move out quickly by Thursday night, around midnight, according to Meteorologist Dallas Raines. Expect temperatures to drop to the 40s at night.
Friday will be a partly cloudy day with cool temperatures expected in the low-60s across the Southland. The high desert will see temperatures in the upper-50s and the mountains will see mid-40s. No rain is expected this weekend. Expect a mix of clouds and sun Saturday and Sunday.
The stronger system could bring more rain in Northern California. Forecasters say the Bay Area mountains may get as much as 7 inches of rain.
Local mountains above 6,500 feet could receive 1 to 2 inches of snowfall from the storm system. In the northern Sierra, the National Weather Service was forecasting as much as 10 inches of snow at higher elevations.
Wind advisories for the San Bernardino and Riverside County mountains expire at 6 p.m. Friday.
While the storm system is welcome, forecasters say California needs much more precipitation to even reach normal rainfall levels and to make up for one of the driest rainy seasons so far.
The totals of rain across Southern California remained under a quarter-inch Thursday and temperatures are expected to return to warm and above-normal temperatures by Wednesday of next week.
