After a slight break with cold and sometimes freezing temperatures in the region, the last half of the Martin Storm Pattern of December 2021 is set to begin this week. For the general outlook, read on for details …
This article will contain both Southern California and Arizona Weather Force’s outlook. First and foremost, we do have yet another series of rain events to hit the forecast areas. The first, west of Los Angeles County will be expected on Wednesday, December 22nd. This slowly moves east with the warm front and eventually will cover the rest of Southern California’s forecast area by Thursday, where most of the rain from this week should fall. As Thursday hits, returning southerly flow into Arizona will start the rainfall there, light at first and then gaining steam through Friday, Christmas Eve.
Each of these rain events has a strong southerly flow with it. As stated in the long range advisory, this southerly flow means that snow-levels will be high at times, in fact most of the time this week. The atmosphere looks to be behaving like last week’s activity where end system snow-levels do eventually drop. We will see more snow this pattern in Kern County’s Mountains than mostly elsewhere due to the fact those areas are shielded from the warmer air and colder air will filter in during the end of the period.
Expecting off and on storms to continue moving through the area through the end of the month, even on Christmas weekend. Travel will be impacted at times then, especially Southern California’s forecast area south and west of the local mountains.
As you can see in the image of this write-up, the in-office forecast model through the end of the month clearly shows a classic sign of a major California storm event with high impacts across the Central/Northern California regions and stretching into the Southern California metro zones. You will also note that there is more rainfall for Los Angeles westward through Ventura/Santa Barbara/San Luis Obispo than say areas like San Diego and don’t even get me started with Imperial. You can also see Arizona’s highest risk area will be the Payson forecast area in terms of precipitation impacts. Like last week, this is a clear signal of a southwesterly flow, which impacts the areas closer to the south and west facing mountain slopes. It is a reason you see less in the Phoenix areas westward and move in areas like Tonto and Payson. Those are the closest areas to the sloping zones to the Mogollon Rim.
SIERRA NEVADA: The Sierra’s stand, as stated in previous updates; to see over 100+ inches of snow by the time this month is over and we are most certainly not done up there yet as we end the snow drought this season.
Over this week, micro-climate alerts and updates will go out on the email alert system, social media accounts, and the main website. As I stated in previous articles days and even weeks ago, continue to hold onto this month as regarded as to be active off and on through the end of it.
A Martin Storm Pattern means that the pattern was predicted before apps or government/private sources, and since my last name is Martin, like a person who discovered a comet, it is only fair this coming pattern is the Martin Storm Pattern of December 2021. There will be MANY Martin Storm Patterns due to my ability to go longer range in weather.
If you do have plans to travel during that time, I would suggest continuing to monitor the latest forecasts here at Southern California Weather Force, however you get them, either by the member email alert system, social media, or checking the main website daily for updates. The ABOUT section of this site will tell you all you need to know about it for navigation. Click here to read the about section.
LONG RANGE: Long range suggests the surface ridge finally moving back to the west and bringing drier conditions the first part of January and then we snap back into the next storm pattern after then, closer to mid-month.

Southern California Weather Force is a custom weather alert service that began in September 1999 off and is regarded as the most accurate weather service in the region, offering custom alerts, maps, and models to help save life and property. The work done here is never 100% accurate, but it comes pretty close. Southern California Weather Force runs on zones, so if an event happens in a zone that is 10 miles from the border of your zone, the forecast is still valid to activate your zone’s alert system. A company quote to the public is that of “The Joker” and tells other agencies in weather this all the time… “This world deserves a better class of meteorologist… and I’m gonna give it to them”… out-forecasting even the National Weather Service with lead-time and precision, which makes this service a focus of ridicule and envy in the weather community due to having such accuracy. Alerts issued here are issued custom from this office and this office alone. You may not even hear it elsewhere, but if one is issued near or in your area, listen up because “if you do not wish to die in weather, follow, it’ll save your life one day.”
