CALIFORNIA - The state of California has been impacted by the first of several frontal boundaries that prompted severe warnings, flash flood warnings, heavy mountain snow, and gusty winds Tuesday into Wednesday morning. The next in a series of fronts moves onshore over the next day or so, adding more to all the previous totals.An active weather pattern will stick around for much of the week, bringing periods of rain, mountain snow, and cool temperatures across the region. While today will not be a total washout, expect scattered showers at times, especially along the Central Coast, as the bulk of the overnight storm system moves out by sunrise. <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2023502650579284209" src="https://x.com/WeatherNation/status/2023502650579284209"></div><h1></h1><h1>Timing</h1>Another system arrives overnight Wednesday into Thursday, delivering another round of rain and mountain snow before tapering off late Thursday afternoon and evening. Several inches of additional snow are expected in the mountains, particularly above 5,000 feet. Snow levels could drop to around 4,000 feet Thursday morning and again Thursday night into early Friday, which means portions of Interstate 5, especially near the Grapevine, could see accumulating snow and lingering slick conditions into Friday morning. Check for road closures and delays as heavy snow will be very impactful across the higher elevations and passes.<video src="https://media.weathernationtv.com/app/uploads/2026/02/jfjfjf1111-1771385148558.mp4" controls="true" width="100%"></video>Rainfall totals with this next system are expected to range from about a quarter to a half inch across the coast and valleys, with up to an inch possible in the mountains. Areas north of Point Conception may see slightly higher totals due to persistent northwest flow keeping showers around longer. Behind the storm, Friday looks dry but chilly. Depending on how quickly skies clear and winds calm overnight, some valleys could experience patchy frost or even freeze conditions early Friday morning.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-18 042722-1771414055691.png">Winter weather alerts have been issued for much of California through Wednesday.<ul><li>2000-2500 feet: up to one foot</li><li>2500-3500 feet: one to two feet</li><li>3500 feet and above: four to eight feet</li><li>wind gusts up to 45-55 mph</li></ul><img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-18 042753-1771414088117.png">Travel could be impossible in some spots with the high snowfall rates and winds. Snowfall totals could surpass 4-5 feet in some areas, like Mammoth Mountain. Resorts around Lake Tahoe could also see 4-5 feet, including I-80 and the Donner Pass. The heavy snowfall rates will make mountain travel impossible at times.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-18 043643-1771414620330.png">Even the mountains in Southern California will see heavy snowfall developing this afternoon and evening. Travel will be very difficult at times through early Thursday.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-18 043710-1771414642809.png">The weekend brings some improvement. Saturday is shaping up to be the nicest day of the next seven as a weak ridge builds overhead. Expect mostly sunny skies, dry conditions, and a modest warm-up with highs climbing into the 60s.&nbsp;However, the quiet weather will not last long. Another Gulf of Alaska system is forecast to move into the Pacific Northwest on Sunday, bringing renewed moisture and unsettled conditions back into Southern California. While most models still vary on timing and coverage, current projections show a 30–40% chance of rain Sunday through Tuesday. At this point, the system does not appear particularly moisture-rich, and rainfall amounts look relatively light.&nbsp;

More record high temperatures were broken across the northern U.S. on Tuesday. Some highs hit nearly 80° in Nebraska.The ridge of high pressure will continue to push east, bringing the heat east through the week.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 161437-1771370084805.png">More record high temperatures will be possible through Friday as the heat builds east.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 161528-1771370135856.png">Temperatures to the south will push towards the 80s on Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 161658-1771370241504.png">The warmest temperatures this week will be Thursday across the Southeast.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 161645-1771370276312.png">The southern Plains will also be feeling the anomalous warmth, helping to increase the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/active-weather-weekend-ahead">severe weather threat</a> there over the next couple of days. Confidence is very high in spring-like warmth sticking around as we head deeper into February.

The West Coast is hogging the active weather in the early part of the week, but it won't last forever. A wave moving onshore in the coming days will turn into another chance for severe storms later this week. But these could look a little different...<h1>SETUP</h1><img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-16 103300-1771263199965.png">The disturbance in question will ripple through the Rocky Mountains, emerging sometime Thursday. That's not the issue-the chunk of energy is more than enough to cause trouble. Let's look at the other ingredients<h1>Moisture &amp; Instability</h1>As the system presses in from the west, a front will drive through some dew points well into the 50's and some 60's. That should be plenty of moisture to work with. That will provide ample unstable air to power severe chances.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-16 103446-1771263317488.png">So if it's all systems go, why are some models struggling to pop storms? Check out the latest run of our in-house model, which is hesitant to develop storms.<hr><video src="https://media.weathernationtv.com/app/uploads/2026/02/02172-1771369980040.mp4" controls="true" width="100%"></video>So what gives? Low-topped supercells are the biggest worry if storms manage to form. Those are storms that don't reach quite as high in the atmosphere, but still contain the ability to rotate. What happens in the evening is a little less certain-do we have enough thunderstorms to merge into a line? Or is the threat going to be limited to the daytime hour?<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 071106-1771337473956.jpg">Even with the uncertainty, the Storm Prediction Center has issued a slight risk for severe weather on Thursday:<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 161153-1771369917849.png">

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

ROCKIES - Widespread winter alerts remain in place across the four corners for additional snowfall for the region. Some parts of Utah and Colorado have already seen over half a foot of snowfall. More is on the way.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 202558-1771385178757.png">On and off rain and snow showers are expected to continue through much of the week, dropping feet of snow for some areas in the Rockies.<video src="https://media.weathernationtv.com/app/uploads/2026/02/0217-1771369170131.mp4" controls="true" width="100%"></video>Snowfall totals could reach 1 to 3 feet in the higher elevations through Thursday morning. The system's track from the Southwest will favor upslope snow in SW Utah and Colorado, increasing totals there, such as Telluride.<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-17 202609-1771385185965.png">Most ski resorts can expect at least 6-12" through Thursday morning, with some seeing up to two feet!Stay tuned to WeatherNation for the latest updates.

NORTHEAST - As this next clipper system continues through, we can see snow and some lake-effect snow. A high-pressure system will move in, and things will taper off on Thursday night.<video src="https://media.weathernationtv.com/app/uploads/2026/02/02-11_rne-1770838643023.mp4" controls="true" width="100%"></video>When all is said and done, the heaviest snow ends up in upstate New York and most of the New England area. With a few of these lake effect bands cranking well into late week, we can see some totals top out at 6"!<img src="https://media.weathernationtv.com/app/uploads/2026/02/Screenshot 2026-02-11 123841-1770838732760.png">But what about those temps after the fact? Well, judging by the Climate Prediction Center's (CPC) 6-10 day outlook, we're likely to continue with these above-average temperatures even after Valentine's Day weekend. It'll also do a good job thawing out some of that snow left behind by this week's clipper!<img src="https://media.weathernationtv.com/app/uploads/2026/02/web5-1770808056886.png">Make sure to stay locked in on WeatherNation!

The Fall season officially arrives Saturday night.

<img class="alignnone wp-image-97394 size-large" src="https://media.weathernationtv.com/app/uploads/2018/09/1-15-728x408.jpg" alt="Fall Starts Saturday Night" width="728" height="408" />

Cooler weather, coincidentally, is on the way just in time for the change in seasons for parts of the country that have seen record warmth the last few days.

<img class="alignnone wp-image-97396 size-large" src="https://media.weathernationtv.com/app/uploads/2018/09/3-11-728x408.jpg" alt="Fall Starts Saturday Night" width="728" height="408" />

The Autumnal Equinox Will happen Saturday evening, the sun will pass directly over the earths equator. The tilt of the Earth's axis in relation to the sun controls the seasons along with the distance of the Earth from the sun along it's elliptical orbit.

As the days get shorter across the N Hemisphere average temperatures will gradually fall.

Here is a view of what the equinox will look like from space. The day and night time line across the Earth will be vertical, and line marking day and night will be oriented north-south.
