Today we have relatively warm weather and mild conditions in San Diego County ... but a storm system that could bring rain and snow is on the horizon.
The quick-moving low-pressure system is expected to move over the region Friday ... bringing with it noticeably cooler weather through Sunday.
The system could also produce light rains throughout the county and snow in the mountains above 35-hundred feet ... with the National Weather Service issuing a winter weather advisory in the mountains from 5 on Friday evening until noon Saturday.
