Somewhat cooler temperatures are expected across San Diego County Tuesday ahead of a low pressure system that will bring a chance of rain later this week.
On Monday, San Diego tied its prior Oct. 12 maximum-temperature reading of 94 degrees, according to the National Weather Service. Isolated rain showers also developed over portions of the county.
Tuesday, partly cloudy conditions and light winds are in the forecast along with high temperatures of 87 to 92 degrees near the beaches, 86 to 91 degrees in the valleys, 82 to 88 degrees in the mountains and around 95 degrees in the deserts.
"Temperatures will begin to cool today and most areas are expected to have high temperatures a few degrees lower than Monday," according to the weather service. "The gradual cooling is expected to continue into the weekend with high temperatures falling to around average."
Chances for heavier precipitation in the form of showers and thunderstorms will increase over the next few days, forecasters said. Still, high temperatures are expected to remain five or so degrees above seasonal averages by Friday.
