Sunny skies and cool conditions over San Diego County were predicted to continue through Monday, the National Weather Service said.
“Clear skies and cool conditions will continue through Monday,” the weather service said. “A warming trend will begin Wednesday and continue through the holiday weekend. No precipitation will occur through next weekend.”
High temperatures Monday were forecast to be in the lower 60s along the coast, mid 60s in the western valleys, lower 60s near the foothills, lower 50s in the mountains and mid 60s in the deserts.
But the mercury was expected to drop in the mid 40s in most areas overnight, and into the 30s in the mountains.
The cool weather prompted officials to activate San Diego’s Inclement Weather Shelter Program on Sunday. The following shelters were opened:
- Father Joe’s Villages, 1501 Imperial Ave. – at the Joan Kroc Center, aid for 45 adults, with an additional 10 beds for families with minor children or single women; check-in starting at 4 p.m. and throughout the night until full. Checkout is at 5 a.m.
- Living Water Church of the Nazarene, 1550 Market St., can take 28 adults with check-in at 8 p.m. and checkout at 6:30 a.m.
- San Diego Rescue Mission, 120 Elm St., can take 10 adults with check-in starting at 5:30 p.m. and throughout the night until full, and checkout at 7 a.m.
An upper-level ridge could begin to build on Wednesday, bringing higher temperatures to the region through the holiday weekend.
The highest temperatures may occur over the holiday weekend, with widespread 70s expected west of the mountains. Some inland valley and lower desert locations could approach 80 degrees for highs next weekend.
No hazardous marine conditions were expected through Thursday.
