NEXT RAIN CHANCE SAN DIEGO: UPDATED SATURDAY 12-26-2020

Our next storm system has moved out of the Gulf of Alaska and is approaching our area from the northwest. Clouds will move into our skies for Sunday, however, it will remain dry and pleasantly mild.

Showers will then overspread Southern California Sunday night into Monday morning. Periods of rain and an occasional downpour will persist through Monday. I can't completely rule out an isolated thunderstorm as well. Most rain will dissipate early Tuesday morning (midday Tuesday in the mountains).

Rain totals will range from 0.5" to 1.0" for coastal and inland regions. Totals in the mountains will range from 1.0" to 3.0". I've included computer projections for rainfall below.

Snow levels will be 5,500 to 6,500 feet Sunday night, then steadily drop through the day Monday. Levels will be 3,500 to 4,500 by Monday night. The highest peaks in San Diego County could see a few inches of accumulation. Higher mountains to the north in San Jacinto and San Bernardino will easily exceed a foot of snow. I've included a computer forecast for snow accumulations below.

NEXT RAIN CHANCE SAN DIEGO: UPDATED MONDAY 12-21-2020

I'm watching a small storm system out in the Pacific, almost halfway between our coast and Hawaii. I've circled it on the satellite image below. 

This system will bring clouds to Southern California on Wednesday and Thursday. A quick shower could develop late Thursday afternoon and evening (40%). Skies will clear out by Christmas afternoon.

I'm still keeping an eye up north in the Gulf of Alaska, where another storm system is brewing. This system could bring our area more substantial rainfall (early projection for rain totals is posted below). Current computer data has this system bringing rain to our area on Monday, 12/28 and Tuesday, 12/29. This system is still thousands of miles away from San Diego, so there will be some fine tuning of the forecast as it approaches. I'll bring more updates in the coming days.
