Temperatures remain cooler than average across the county alongside a dense marine layer (especially in the morning) and moderate breeze. A trough of low pressure is responsible for the cooling trend that's occurred over the last several days and even the drizzle that came over the weekend at times. Now, while this trough moves east and out of the region, it will still take some time for a ridge of high pressure to build in its place. This will translate to cooler than normal temperatures for nearly the entirety of the week with daily morning clouds. Much warmer temperatures can be expected from this Friday through the upcoming weekend. https://www.cbs8.com/article/news/local/san-diego-weather-update/509-addbcd08-0811-489a-b511-7cd202ccde99
