Cool weather was forecast in San Diego County on Sunday, and a storm from the north could bring rain, wind and mountain snow to Southern California late next week, the National Weather Service said.
A low-pressure system “could bring widespread rain and mountain snow to the region Thursday into Friday” according to the latest forecast.
On Sunday morning, areas of dense fog will affect portions of the inland valleys, and king tides near 7 feet could lead to minor coastal flooding, mainly in low-lying beach parking lots and boardwalks, the weather service said.
High temperatures Sunday were forecast to be 62 to 67 near the coast, 66 to 71 inland, 68 to 73 in the western valleys, 72 to 77 near the foothills, 67 to 74 in the mountains and 82 to 87 in the deserts.
Weak northeasterly winds were expected to develop Sunday in the foothills, the weather service said. The northeasterly flow will combine with a brief ridge aloft to bring warmer weather.
However, an approaching low-pressure system could bring gusty westerly winds late Monday into Tuesday, with possible drizzle west of the mountains Monday night.
The notable weather event next week was expected to be the broad system across the western United States on Thursday and Friday, meaning the county could finally get some meaningful rainfall, the first since October, the weather service said. Rainfall amounts could exceed a half-inch in some locations, most likely in the foothills and west-facing mountain slopes.
No hazardous marine weather conditions were expected through Wednesday, but gusty onshore winds near 20 to 25 knots were expected by Thursday and Friday.
