Severe Thunderstorm Watch: Southern California Projected to have Severe Thunderstorms Thursday Evening into Friday Morning

Southern California Weather Force has issued a Severe Thunderstorm Watch effective this evening through the overnight and Friday morning for the following areas;

Issued Zones: Los Angeles, Orange, San Diego County … The Inland Empire, High Desert and Cajon Pass … San Bernardino and Riverside Mountains …

Date Issued: November 20th 2025 at 10:30am PT

Discussion: What looks likely the largest thunderstorm producing storm this season will hit this evening and overnight to Friday. Strong upper divergence from a diving upper level low out of the northwest, similar to the early Valentine’s Day storm will produce severe thunderstorms across the watch area. Most of this should be rain in the mountain areas until after it passes with the colder air moving in and instability out. Frequent Lightning, Isolated Tornadoes, Hail, Damaging Winds, and Flooding will all be in the cards. This is an exclusive forecast for severe thunderstorms here at SCWF you won’t see elsewhere so enjoy the show and stay safe.

A Severe Thunderstorm Watch is issued at Southern California Weather Force when conditions are possible for severe thunderstorms, covering over 50% of the watch zone, with damaging winds of over 50 mph and large hail in the stronger storms. Severe Thunderstorm Watches at Southern California Weather Force are private, issued ahead of time to the public by SCWF as the lead-time is extremely important to you.

STORM SYSTEM DETAILS FOR THURSDAY INTO SATURDAY

Southern California Weather Force Raiden Storm has issued the zoom in maps for predicted rain and snowfall. These maps are extremely easy to read, and feed a different code than many. Those of you that have been with me for years will have missed these maps.

NOTE: Get the zoom-in model maps at this link - https://www.southerncaliforniaweatherforce.com/2025/11/19/storm-system-impact-southern-california-thursday-into-saturday-rain-and-snow-maps/

Areas within the red would need flood watches during this event, with heavy snow also happening in the local mountains. You can see the predicted amount from my snowfall model within this write-up link.

Thunderstorm Dynamics will exist Thursday evening, night, and Friday morning for Los Angeles, Orange, Inland Empire, and the San Diego County zones, and surrounding mountains, some could see thundersnow.

Next Storm System to Impact Southern California Bringing Periods of Rain and Possibly T-Storms for Some:

Rain begins Thursday morning in SLO, Santa Barbara, and Ventura, spreading south through the day. Heaviest rain hits LA and Riverside Thursday evening and reaches San Diego by nighttime. Flood prone areas should stay alert.

Early Friday, storms shift out quickly, but rebuilding instability plus moisture may allow a few thunderstorms in San Diego and Orange County with lightning, small hail, and gusty winds. A very low end waterspout or weak tornado risk cannot be ruled out.

Lingering moisture will keep scattered showers going, with steadier rain possible toward Vegas depending on system track.

Stay tuned for updates from Raiden Storm and I (Sina)...

2pm PT Tuesday Forecast UPDATE:
Periods of showers, with a few heavy ones, have already moved through, with remnant moisture still lingering after the cold front passed through our region. Scattered activity on and off will continue throughout today before diminishing. Most areas will have mostly cloudy skies today, but a stray shower is still possible given the lingering moisture.

What is next up?
Another storm system is expected to slowly move into our region around Thursday, roughly around 11pm PT. Ahead of the system, scattered showers may develop before the main system pushes through on Friday afternoon. This system will also bring periods of moderate to heavy rain through early Saturday morning before becoming scattered once again. Convective activity will be monitored for any thunderstorms, and an update will be issued at a later time.

For now, enjoy the partial break today with mostly cloudy skies and occasional sunshine before the next system slowly moves in on Thursday night.

Snow levels and details will be on the next update. It is already available on ZoneWatch pro products ("snowfall totals").

Next Fast Moving Storm System to Bring More Heavy Rainfall and Mountain Snow:

12pm PT Monday Forecast UPDATE:
Hope you're enjoying the breaks in the clouds with a lot of areas getting nice sunshine with some very beautiful sunrises across southern CA before our next storm system which will be fast moves in...This system is expected to impact northern portions of Southern CA as soon as 2-3pm as a line of moderate to heavy showers move in from Santa Barbara into Ventura then LA followed by the rest of the forecast area with time reaching San Diego around 10-11pm tonight.

In terms of thunderstorm risk... the risk is extremely low given that the right ingredients for t-storms are lacking significantly for most of southern CA with most of this system being a rain producer heavy at times but not as potent as the previous storm system with a lot more of a fast punch then scattered showers similar to yesterday on and off behind it through Tuesday evening/night across Southern CA...(pop up storms from lingering moistures behind the main system).

Snow levels:
This system will be much colder compared to our previous system so we're expecting snow around 6kft elevation that will stick and some areas in higher elevations will most definitely get some heavier snowfall... Check ZoneWatch snowfall model pressing NAM3k or HRRR 18z run (as of now) drag it all the way across to see the total snowfall amounts for your specific region or if your planning a trip to the mountains...

For now if you're not in northern portions of Southern CA, enjoy the sunshine and broken clouds before the next fast moving storm system pushes through.

Next Storm System to Impact Southern California Bringing More Heavy Rainfall:

1 PM PT Sunday Forecast Update (with Video Explanation)
Scattered showers and occasional stronger pop up storms will continue this afternoon and evening across Southern California, with brief heavy rain, small hail, and gusty winds possible. Activity becomes more on and off through tonight as remaining moisture lingers.

The next storm system arrives Monday morning between 6 and 9 AM, bringing a fast moving line of moderate to heavy rain across the region. Thunderstorms are unlikely due to limited instability, but heavier rain bands will still produce brief downpours. That being said as the first wave of storms move through, we will be monitoring for potential pop of t-storms should ingredients align...

Santa Barbara and northern Southern California will see the highest impacts again, with Los Angeles, Long Beach, and northern San Diego also picking up 1.5 to 4 inches of rain, locally higher in flood prone areas already hit hard by the last storm.

Overall: The previous system was powerful, delivering significant flooding and wind damage in parts of the region and unfortunately resulting in loss of life.

Stay tuned for updates from Kevin and I (Sina)...not Kevins wife... haha

12am PT Sunday Forecast UPDATE:
A few of our members and lightning strike maps (on ZoneWatch) have already confirmed a few thunderstorms across the mountains and surrounding areas in a hit or miss fashion. This system’s most intense impacts were the flooding and the winds, which significantly affected Ventura, Santa Barbara, and portions of LA.
It brought damaging winds that knocked down trees as well as flooding, some of which was major, unfortunately causing lives to be lost and a child to be reported missing (more updates on the damage report coming soon).

Scattered showers and a few thunderstorms remain possible all night across Southern CA, especially during the morning hours for San Diego and Riverside County. As the system slowly moves out, we will see an intermittent break with mainly cloudy skies and occasional sun before the next system arrives.

Overnight, instability will increase, especially during the morning hours if enough clearing and some heating occur, bringing the risk of brief heavy rain from cells and perhaps a few isolated thunderstorms, hit or miss, at least until around 2pm PT. Lingering showers will continue on and off through all of Sunday. There will not be much of a significant break, as the next storm system will follow quickly behind with a fast hitting type of impact. Details will come in the morning update.

Enjoy the scattered thunderstorm activity and the on and off moderate to heavy rainfall producing storms, and if you get hit by a thunderstorm, feel free to report it in the comments below.

Forecast Update as of 1pm PT:
Heavier bands of rain embedded within steady rainfall continue to increase in coverage across most of Southern CA, with some areas experiencing very concentrated heavy rain bands. Some of the main focus areas have been across the northern portions of Southern CA. Widespread flooding is already being reported, with some areas seeing minor flooding while others are experiencing more significant impacts. As we stated previously, we are still just getting started with the heavier portion of the rain, and coverage will continue to increase.

After all this, rainfall totals will be posted on the page Sina Moghaddami...

Lets talk other dynamics as well which will come a bit later...(evening - Sunday morning)

Thunderstorm Dynamics:

Later in the evening, there is an expectation of some clearing or a pause in the rain, which will allow instability to build and support potential lines of thunderstorms that may be strong with a few intense cells... given the dynamics, almost all metro areas are at risk for widespread thunderstorm activity becoming more scattered with time... all night into the early morning hours... Hit or Miss so if your area doesn't get hit, does not mean that's the case for everyone...

Any thunderstorms will be capable of heavy rainfall, frequent cloud to ground lightning, small hail, and gusty winds... and perhaps even an isolated tornado or funnel cloud if dynamics align...

We will also continue to monitor thunderstorm risks, as mentioned, since conditions could become more interesting later tonight, but this will be monitored closely.

Gusty Wind Dynamics:

Later in the evening after 4pm, winds will also start to increase as the main low approaches the region just southwest of the forecast area. Winds can gust between 20 and 40 mph, with some locations locally over 55 mph... and this does not include any stronger wind gusts that may occur with stronger thunderstorms...

Check out all the details on ZoneWatch, including scenario future radar and other products and alerts.

Flood Emergency continues...
