Sunny skies and cool conditions over San Diego County were predicted to continue Sunday through Monday, the National Weather Service said.
High temperatures Sunday were expected to be nearly identical to Saturday west of the mountains. The mountains and deserts could warm up a bit compared to Saturday. Temperatures Sunday were mostly expected to be in the 60s, with overnight lows in the 40s. The mountains were expected to be in the upper 40s, dropping into the mid-30s overnight, and highs in the deserts were forecast to be in the mid-60s with lows in the lower 40s.
Weak transitory ridging could begin to build in later Sunday and continue through Monday, before a weak shortwave from the northwest moves in late Monday night into Tuesday, forecasters said. This was predicted to bring more high clouds into the region Tuesday into Wednesday. No precipitation or strong winds were expected with this system.
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 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.
