Warm Days, Cool Nights Expected For San Diego County
High pressure will bring warm days and cool nights across San Diego this weekend and into next week, the National Weather Service said Saturday.
A shallow moist layer will bring areas of dense fog near the coast and over the coastal waters, while higher clouds drift overhead through Sunday, forecasters said.
"We will see a noticeable change in the weather by the end of next week as a trough brings much cooler weather with strong westerly winds over the mountains and deserts, and even a chance for some light precipitation west of the mountains," the NWS said.
High temperatures Saturday along the coast were expected to be 73-78 degrees with overnight lows of 51-59. Inland valley highs will be 85-90 with overnight lows of 53-59.
Mountain highs were expected to be 73-80 with overnight lows of 46-56. Desert highs will be around 89 with overnight lows of 56-66.
Looking ahead to Tuesday, forecasters expect a slight decrease in temperatures west of the mountains as onshore flow begins to dominate.
But above-average temperatures will return Wednesday into Thursday as a high-pressure ridge strengthens, the NWS said.
"Temperatures will once again make it again into the lows 90s in parts of the San Diego County valleys," forecasters said.
