|SYNOPSIS FROM THE SAN DIEGO OFFICE
Seasonably cool with increasing clouds today. A series of storm systems will then move through the region tonight through early Tuesday. Rain and mountain snow will be heaviest and westerly winds will be strongest Thursday morning, Friday afternoon and Sunday night into Monday, along with a slight chance of thunderstorms Thursday and Friday. Dry weather is expected to return on Tuesday.
Radar indicates showers still north and west of Point Conception, but will likely move into Southern California this evening, increasing in coverage and intensity overnight as a storm system moves into the region. Periods of heavy rain and snow will affect some areas and there is enough instability for a slight chance of thunderstorms. The snow level will drop to about 5000 feet. Strong winds will be felt in most but not all areas. The mountains and adjacent deserts will be most impacted by the strong winds. This system will move through fairly quickly and showers will decrease Thursday afternoon and evening.
