System from Alaska to bring San Diego County scattered rain, potential for snow
A low pressure system is moving through California and will bring much cooler temperatures, breezy westerly winds, some light rain and possible snowfall to San Diego for the next two days.
Winds will be the first noticeable change Thursday evening as southwest to westerly winds pick up in the mountains and deserts, carrying gusts of 35 to 45 mph. Winds will pick up again across the region for much of Friday afternoon.
On and off showers are expected starting as early as late Thursday evening with less coverage by Saturday early afternoon. This will be a bit of a splash-and-dash system with periods of light rainfall. Saturday late afternoon and evening look mainly dry.
Most areas expected to see the scattered showers are looking a tenth inch of rain to locally a quarter inch.
This is a cold storm system originating from the Gulf of Alaska, so stretches across California are expected to get a round of snow.
Locally, snow levels will drop to about 5,000 feet in elevation by Saturday morning, so any lingering precipitation could change over to a light dusting of snow in higher-elevation mountain areas.
As far as temperatures go, our afternoon highs for Friday could be 15 to 20 degrees colder than Thursday’s, particularly in mountain areas.
Friday daytime highs for coastal and inland areas will top out in the low 60s, mid to upper 40s in the mountains and mid-60s for the deserts.
Overnight conditions will be chilly and somewhat cloudy with low temperatures bottoming in out in the low 40s for inland valleys and low 30s for the mountains.
