High clouds will fly across the region Friday morning. Some scattered light rain may fall Friday afternoon ahead of the system that will bring us rain over the weekend.
A High Surf Advisory has been issued for San Diego County beaches from 4 AM Saturday until 4 AM Monday. Surf will rise to 6'-8' this weekend, with sets up to 9' possible. A high risk of rip currents will make swimming conditions dangerous. Surf will subside into Monday morning.
THE WEEK AHEAD:
High pressure will weaken Saturday as low pressure impacts the West Coast. The center of the storm will pass over Northern California. Much of the energy and moisture will stay far to the north of San Diego County, leaving little in terms of rain for Southern California.
Scattered light rain will fall Saturday and Sunday as a band of moisture moves in Southern California. Much of the rain will be centered over the mountains with coastal and inland areas seeing drizzle or light rain. More rain will come Sunday night as a pocket of energy comes across Southern California, but moisture levels will remain fairly low. Light rain may last into the early hours of Monday morning. Total rain accumulations for this weekend storm about 0.1"-0.3" at the coast, 0.2"-0.4" inland, and up to 0.5" for the mountains.
High pressure will strengthen briefly Monday into Tuesday, with temperatures rising slightly. A small trough of low pressure will drop temperatures slightly around midweek next week.
Stronger high pressure looks like it will form late next week, leading to warmer conditions for next weekend. The forecast shows that afternoon high temperatures can reach 5-10 degrees above average.
