The National Weather Service said that it is expected that the temperature in the inland areas of San Diego County will be too high from Saturday to Monday, while the coastal areas are still affected by the ocean layer, with sporadic low clouds and fog every night and morning.

Forecasters say there may be isolated light showers or thunderstorms on the higher peaks this weekend, and there is a better chance early next week.

As the high-rise highs in the southwest weaken, the heat is expected to begin to weaken on Tuesday.

The high temperature in the coastal area on Saturday is expected to be 73-78 degrees, and the lowest temperature at night is 61-66 degrees. The high point in the western valley is 83-88, the high point near the foothills is 91-96, and the overnight low is 62-67.

The highest point in the mountains is expected to be 92-102, and the lowest overnight point is 64-74. The highest point in the desert is 115-120, and the lowest overnight is 88-93.

On Saturdays and Sundays, the weather near and below the desert passage is very hot. Gusts from southwest to west winds and a minimum of about 15% daytime humidity are expected to increase fire weather conditions.

By the beginning of next week, moderately unstable conditions may increase the likelihood of fires dominated by plumes in mountainous areas.

The chance of dry thunder on the mountain this weekend is 10%.

It is expected that by Sunday, with the development of vortices, low clouds and fog in the ocean layer at night and in the morning will become more common in coastal areas and gradually extend inland within a week.
