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.

WEATHER UPDATE: 9 AM FRIDAY 4-10-2020

An area of rain with embedded downpours is moving across the area. Showers will become more scattered into the afternoon and evening. The chance for rain completely diminishes by Saturday morning. Another slight chance for isolated showers arrives on Sunday.

Flood warnings are in affect for some areas in San Diego County. You can find all advisories and warnings on the National Weather Service website:

https://alerts.weather.gov/cap/wwaatmget.php?x=CAC073&y=1

Snow levels will remain around 4,500 to 5,500 feet through tonight. You can find the latest road conditions in the mountains here:

https://roads.dot.ca.gov/

I have a 5-day running tally of rainfall updated at 8 AM. Some areas are approaching 5" of rain. Here is the link:

Stay safe out there!

WEATHER UPDATE: 1 PM WEDNESDAY 4-8-2020

I've attached a really cool satellite loop below. It shows the core of the storm spiraling off our coastline. Our chances for rain will continue until that core exits the region.

A few showers will push eastward this afternoon, then more persistent rain will develop tonight into early Thursday. Sporadic showers will then linger on-and-off through Thursday. The latest computer data shows this system moving a little slower than earlier anticipated, so the rain chances will persist all day Friday as well. A little hail could accompany isolated downpours.

I'm still expecting snow levels to hover around 4,500 to 5,500 feet.

A Flash Flood Watch and a Winter Weather Advisory are in effect. As always, you can find the latest at the National Weather Service website:

https://www.weather.gov/sgx/

I'll keep updating rain totals on my previous blog post.

https://sandiegoweathercenter.blogspot.com/2020/04/san-diego-rain-totals-sunday-4-5-2020.html

Another front will bring a chance for isolated showers on Sunday, though it doesn't look like a washout.

WEATHER UPDATE: SATURDAY 4-4-2020

There are no major changes to the forecast. The next system is diving southward off the coast or Oregon. The core of the system is indicated in the deep shades of blue in the satellite loop below. This will bring us a chance for rain from Sunday through Thursday.

Isolated light showers could occasionally pop up tomorrow (30%), though it looks like most of the day will be dry. A better chance for rain arrives Monday as the core of the system settles into the region (80%).

The rain chance persists Tuesday and Wednesday (80%) as more moisture gets wrapped up into the storm. Computer forecasts have been a little inconsistent about the track of the storm during this time period. This track is key to the forecast because it affects our overall rain potential. The atmosphere will be unstable, so isolated downpours will be embedded within the showers. Some hail will also be possible.

Showers will become more isolated heading into Thursday as the system exits the region (60%).

Snow levels will be around 9,000-10,000 feet Sunday, 5,500-6,500 feet Monday, 4,500-5,500 feet Tuesday and Wednesday, then back up to near 5,500-6,500 feet on Thursday.

I've included projected 5-day rain and snow totals below. It shows that most areas in San Diego County should receive 1-2" of total rain with isolated areas in the mountains getting more.

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 4-1-2020

Computer forecasts have significantly accelerated the next storm system. This is going to prevent the warm up for this upcoming weekend. High temperatures will remain below average for the foreseeable future.

Looking at the satellite loop below, you can see the overall flow of the upper atmosphere. There is a direct path connecting California to Alaska. Our next system will take this trajectory and park off the coast for the start of next week.

Isolated showers are possible ahead of this system on Sunday (30%). A better chance for rain arrives Monday, especially late in the day (60%).

Computer forecasts are having difficulty dealing with this system afterwards. Some are showing this system stalling and drawing moisture into our area Tuesday. This could greatly enhance our rainfall potential. It's still too early for me to give a definitive forecast. I'll keep an eye on it and bring more updates in the coming days. For the time being, I'm leaving rain in the forecast for both Tuesday (60%) and Wednesday (40%) of next week.

Snow levels could drop low enough by Wednesday for local mountains to see some flakes. Again, it's still too early to give specifics.
