<body><div><p>11/12/26 Thursday 4:30 am</p><p>I have been concentrating on the bigger picture the last few days; it’s time to slow down and focus on the upcoming weekend.</p><p><b>Overview</b></p><p>Friday night, a small but moist closed low will come onshore near San Diego. This is subtropical moisture, so a little goes a long way. As the low moves east into Arizona and eventually New Mexico, just enough moisture will reach our area.</p><p>While this is happening, a monster low-pressure system that has been tormenting the Canadian West Coast areas will drop down the California Coast. This system is intense. The models show this system’s internal pressure at 960 mb. That is the equivalent of a Category 3 hurricane. Extremely cold Arctic air is entrained in this monster; it is showing heights down to 516 mb.</p><p>I was not planning on showing this, but I downloaded the images already so I could zoom in and see them better, so here we go.</p><p>That system is at the top right of the page.</p><figure><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=1T5BeW_1H364Ms500" alt="https://img.particlenews.com/image.php?url=1T5BeW_1H364Ms500" width="984" height="808" ></figure><p>Then I zoomed in on the system to double-check the intensity.</p><figure><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=0N2n23_1H364Ms500" alt="https://img.particlenews.com/image.php?url=0N2n23_1H364Ms500" width="353" height="370" ></figure><p>If you recall my post a week ago about snow levels, I explained the snow-level cheat codes based on millibars and elevations. In that same discussion, I talked about snow levels based on “thickness” levels. I will post a link to it at the end of this post.</p><p>In the above image, you see the first blue line, then 4 more. The first one is 540 mb; the next is 534 mb, then 528 mb, 522 mb then 516 mb. This indicates polar air being brought down from the Arctic.</p><p><b>Here is where all of this comes back to our area this weekend.</b> That system will moderate as it approaches Northern California, but it is so huge that it will push cold air into our area and mix with the subtropical moisture from the earlier-mentioned small closed low to produce snow, with a 552 mb thickness level indicating snow at or above 8,000-8,500 feet.</p><p>How much? Not much according to the latest model runs… The passes will likely see 4-8 inches of snow. Below the snow levels, the lower elevations will see rain in the 0.50-inch range; this could change, so I am keeping a close eye on any changes in the precipitation totals</p><p>Obviously, I got distracted by that monster system, which long-time followers know means I did not get much sleep. Oh well.</p><p>I will be back around noon or 1:00 pm. The El Niño update is coming out today; it should be interesting. I will try not to get too distracted by it.</p><h2>Venmo: @Jeff-Givens-11 </h2><h2>OR</h2><h2>Cash App users: $JGDWG</h2><h2>ZELLE: jgivenscbr@gmail.com</h2><h2>Prefer to send a check?
