High pressure and weak Santa Ana winds were predicted to bring warmer and drier weather this weekend in San Diego County, the National Weather Service said Saturday.
A return to onshore flow was expected to spread marine air and cooling inland beginning Tuesday and continuing for the remainder of the week, the NWS said.
High temperatures along the coast Saturday were predicted to be 65 to 70 degrees with overnight lows of 50 to 55. Valley highs were expected to be 71 to 76 with overnight lows of 49 to 54.
Highs in the mountains were expected to be 64 to 71 with overnight lows of 43 to 50, and highs in the deserts were predicted to be 83 to 88 with overnight lows of 55 to 63.
Above-normal temperatures were forecast for Monday.
Cooling was expected west of the mountains Tuesday as onshore flow returns, but the low deserts may continue to heat up with highs in the upper 90s and subtle cooling on Wednesday.
The marine layer may return by Tuesday morning with fog, possibly dense, along the coast. The marine layer is expected to deepen through the week with low clouds and fog extending farther inland each night and morning.
For Friday, precipitation remains unlikely, but can’t be ruled out completely, forecasters said.
Winds should continue to diminish over coastal waters through Saturday afternoon. Wind gusts may briefly exceed 20 knots in the afternoon and evening Saturday and Sunday.
