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.

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 12-16-2020

A storm system is approaching the West Coast and will bring clouds to our skies by this evening. You can spot the clouds on the satellite loop below. Unfortunately, the core of this system will miss our area, so our rain chances are limited. 

We will have clouds and some winds through Thursday. Isolated light showers could develop by Thursday late afternoon into Thursday night (40%). Skies should clear out by Friday morning. 

I'm continuing to watch the long range computer forecasts for any chance of real rainfall. We could see a brief shift in the weather pattern after Christmas. Otherwise, it's looking mostly dry. La Nina is still strong along the Equatorial Pacific (indicated by the shades of blue below). Hopefully this will weaken later in the winter so that we can see some better rain chances by the end of rain season. Fingers crossed!

WEATHER UPDATE: 7 PM FRIDAY 11-6-2020

The storm system is now on our door step. You can see the center of the storm off the coast of San Francisco in the satellite and radar loops below. 

Patchy drizzle will pass the area tonight. Then periods of rain with embedded isolated downpours will persist on-and-off through Saturday. Snow levels will stay around 6,000 to 7,000 most of the day.

A second system will follow the heels of Saturday's storm. This will bring more intermittent showers through the day on Sunday. Snow levels will drop to 5,000 to 6,000 feet by Sunday evening.

I've included computer projections for 2-day rain totals through Sunday. Coastal and inland areas will see 0.5" to 1.5". Isolated areas in the mountains will exceed 2.0".

I've also included snow projections, which shows higher elevation mountains to the north getting significant snowfall. Local mountains in San Diego County could see some snow, but the ground is so warm, it will be tough for it to accumulate.

NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 11-1-2020

I've been keeping a close eye on the Gulf of Alaska. This area will slowly become energized in the coming days. I've included a satellite loop below, where you can see a deep shade of blue at the top of the image - indicating the jet stream migrating southward.

The European computer forecast has been very consistent with a storm system diving out of this region and into our area by Friday night into Saturday. Unfortunately, there isn't much moisture available, which will limit our rain chances. Regardless, scattered showers should be possible through Saturday (40%).

This will be the start of a general cooling trend heading into the second week of November. Hopefully this will also lead to more rain chances. It's an uphill battle though: La Nina continues in the equatorial Pacific.

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 10-21-2020

It's time to dust off the blog and gear up for the upcoming rain season!

All eyes are up in Canada, where a storm system is diving southward towards the Southwest United States (it's hard to spot on the satellite loop below). This will bring Southern California our first rain chance this season. This storm track isn't ideal for substantial rain, but we'll take anything at this point!

Isolated showers are possible on Sunday, then a better chance for showers arrives Monday. Rain totals will be low: less than a quarter inch. We will also get a taste of some cooler air next week.

Looking at the long term weather pattern, we are going to experience a La Nina winter. I've included water temperature anomalies below. You can spot the cooler water off the west coast of Peru.

La Nina typically brings warm and dry weather for winter in Southern California. The cool water temperatures are fairly deep, which means that this La Nina should persist through most of winter. Obviously there are exceptions to the rule, however, it's not looking good for rainfall this winter. I'll keep watching the pattern and bring updates.

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 4-15-202

A small storm system is migrating southward along the California coast (seen on the satellite loop below). Clouds will stream into our skies tomorrow ahead of this system. A few isolated showers could pop up Friday, especially late in the day (30%). The rain chance diminishes by early Saturday morning.

I'm watching another system that could bring some showers Monday into Tuesday of next week.

Both storms are lacking moisture, so rain totals will be limited in Southern California. Also, snow levels will be high, so I'm not expecting snow in local mountains of San Diego County.
