The first of two weak weather systems brought patchy, light rain showers to San Diego County on Monday morning, the National Weather Service reported.
“A weak weather system will bring scattered light rain showers from the coast to the foothills early this morning,” the agency said. “A colder system will bring light showers tonight into early Wednesday.”
A broad trough was expected to remain in place along the West Coast much of this week, steering weak disturbances and pockets of moisture to the county.
High temperatures on Monday will be in the lower 60s along the coast and in the western valleys, the mid 50s near the foothills, the upper 40s in the mountains and around 70 in the deserts.
