Turning drastically cooler for the rest of the week, as winter weather returns to San Diego.
Today has been mild, but a lot more clouds have been building around the county as we transition to colder and unsettled weather. Thursday will be about 10-15 degrees cooler than today, with winds picking up in the afternoon. A Wind Advisory will go in effect at noon on Thursday until midnight for our mountains and deserts. Winds out of the southwest will range from 20 to 30 mph with gusts of 50-70 mph.
The chance for showers will increase by Thursday evening with widespread rain on Friday and a slight chance of thunderstorms. The greatest impact will be Friday morning with showers becoming less widespread and more scattered by the afternoon and evening. Isolated to scattered showers will continue into Saturday, with the best chance in the afternoon and evening, with just a slight chance for any showers to linger into Sunday. Sunday afternoon will be drier with cool air lingering into next week.
Rainfall totals will average between .25 to 1.00" for the coast and valleys with .75 - 2.00" in the mountains and less than .25" in the deserts.
Snow levels will drop each day starting around 5,000' on Friday. Snow levels will drop to 4,000' Saturday and Sunday. A Winter Storm Watch begin Thursday night through Sunday morning.
Snow totals above 5,000' will average between 3 to 6", that includes Mt. Laguna and Palomar Mountain. Areas at 4,000' and 5,000' expect 1 to 3", which means lighter snow totals for Julian and Ranchita.
Cooler than normal temperatures will stick around into the weekend, with highs in the mid-50s to low-60s for the coast and valleys, 30s and 40s in the mountains and 60s in the deserts. Temperatures will recover by 10 degrees, but most areas will average below normal through Tuesday.
