One-day rainstorm to strike on Oscar Sunday

The Southland was treated to more mild temperatures on Saturday before a storm system out of Canada triggers a day of showers on Oscar Sunday, forecasters said.  

Sunday's forecast for the greater Los Angeles area calls for a chance of rain in the morning, and likely showers in the afternoon, according to the National Weather Service.  

Sunday's high in downtown Los Angeles is forecast at 61 degrees, a drop of 10 degrees from Saturday.  

A winter storm watch is in effect in the Los Angeles County mountains from Sunday afternoon through early Monday, in which the NWS warned of accumulating snow and possibly damaging northeast winds.

The weather could impact Interstate 5 over the Grapevine and Highway 14 in the Antelope Valley, where drivers were advised to expect slippery road conditions, reduced visibility, and strong crosswinds.  

Sunny skies are expected to return to the Southland on Monday.
