Cool weather was forecast to continue in San Diego County on Sunday, but the region will warm up next week, the National Weather Service said.
Temperatures were forecast to be 5 to 10 degrees below normal, with the marine layer stretching 20 to 25 miles inland.
“Seasonally cool weather this weekend will transition to warmer weather next week as weak Santa Ana conditions push easterly winds through the passes and along the coastal mountain slopes,” the weather service said.
Highs on Sunday were forecast to be 70 to 75 near the coast, 74 to 79 inland, 77 to 82 in the western valleys, 81 to 86 near the foothills, 78 to 86 in the mountains and 99 to 104 in the deserts.
The weather service said gusty winds through the mountain passes and along the desert-slopes will increase to 30 to 40 mph and create fire weather conditions in the afternoon.
