An upper-level low-pressure system that has been sitting off the Baja peninsula for days should spin a few showers ashore in Southern California Sunday, mostly in the afternoon, according to the National Weather Service (NWS).
Scattered showers across the Los Angeles Basin are possible, with as much as a tenth of a inch of precipitation in some spots.
The weak system will be wet enough for Angelenos to turn off their lawn sprinklers for a day or two, but it will not bring snow -- drinking water in the spring -- to the southern Sierra Nevada, which is nearly dry so far this season, NWS Meteorologist Dave Bruno said.
In and around Los Angeles, the day should start out cloudy with a slight chance of showers. Highs will be mostly in the lower 60s.
It should be good running weather for the Los Angeles Half Marathon, which starts on Ocean Front Walk in Venice, heads south along the beach, winds around Marina del Rey, crosses Ballona Creek into Playa del Rey and heads south into El Segundo, turns around and finishes at Lagoon Park in Playa del Rey. The starter's gun for the main race is set to go off at 7 a.m.
The best chance of showers will be this afternoon and will continue into Sunday evening.
Monday, the celebration of Martin Luther King Jr.'s birthday, should be cool and dry, with highs in the upper 50s and low 60s. Tuesday, which could start out foggy, should be about the same.
The next chance of "a real rain," Bruno said, should arrive the latter half of next weekend. Weather models show a southward sagging jet stream poised to bring wet weather out of the North Pacific and southeast across the state, bringing a healthy dose of snow to the Sierra Nevada.
Though Los Angeles got some early season rain, it has been unusually dry and hot since before Christmas, producing beach days rivaling the midsummer.
Since July 1, the NWS weather station at USC has logged 3.76 inches, well behind the seasonal norm of 5.56 inches for this time of year. Last year about this time, Los Angeles had a whopping 12.28 inches -- just shy of annual average rainfall total, about 15 inches.
Along Los Angeles County beaches, look for a building northwest swell, with the surf in the 1-3 foot range, and the water temperature about 60 degrees.
