As the northwest eagerly awaits some dry time, it's going to come at another's expense. California will be the next in line to pick up heavy rain and snow looking ahead, as the pattern doesn't change, it merely moves.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 093822-1765989621213.png">Areas up and down the Sierra Nevada Mountains are in desperate need of snow, though. This year, we've picked up around 20% of what we normally should by this time of year. We'll try to change that going into the next few days. As the firehose drops south late this week into the weekend, rain will initially be the biggest concern. Snow levels will struggle to get all the way down to pass level at first, with this being a bit of a warm system.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 094054-1765989784668.png">But moving into the weekend, the snow levels will drop. But the best moisture might ultimately end up in the southern portion of the mountain range.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-17 rsw-1766022009083.mp4" controls="true" width="100%"></video>Heavy, persistent rain will be the greatest threat going into the weekend, as it may not let up before rolling into the holiday travel week. By then, some areas could be staring down rainfall totals surpassing a FOOT!<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 183921-1766022016353.png"><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 183926-1766022020934.png">This is a ways away, however, so be sure to check back with the forecast as we grow closer to the weekend.

NORTHERN PLAINS - A low-pressure system originating from the northwest has been pushing through the Plains and into the Great Lakes. This system will move into some warmer air, so models are favoring more rainfall as opposed to snowfall. There are winter alerts and blizzard warnings that remain in effect for snow and low visibility.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 182905-1766021386515.png">Currently, from recent clipper systems, there is a decent snowpack on the ground across these states.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 183045-1766021450949.png">With this next system moving in and bringing rain, this could lead to a bit of slush out there as the rain melts away the snowfall. The system moves through fast and over the Midwest and into the northeast on Thursday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-17_RNC BAMS3K-1766021461538.mp4" controls="true" width="100%"></video>Precipitation totals look to be fairly minimal because of the speed at which this system moves through.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 183622-1766021789476.png">For some, temperatures will be impacted by this front. For instance, look at Bismarck, North Dakota, a high of 42 on Wednesday and 30 degrees cooler by Thursday with a high of 10.For more details on this, be sure to join us on WeatherNation live!

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!

Does it feel like deja vu? This persistent pattern, locked in for most of December, has some side effects. No snow for the west! While areas around the Midwest are experiencing their snowiest start to the Winter in years, areas out west are looking at their slowest start to the water year.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 090611-1765987589484.png">Take, for instance, the Pacific Northwest. They've been seeing the worst of both patterns: warm systems that bring inundating rainfall to the area, without the benefits of slow-melting snowfall, keeping watersheds fed with a much-needed, consistent water source.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 140808-1766005705355.png">Other areas like Colorado have seen a fairly soggy past month, but got off to one of the latest starts to winter on record in Denver. Similarly, like the northwest was struggling, any shot at moisture fell at once, as rain.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 141243-1766005981387.png">All of this information comes from the National Integrated Drought Information System, an offshoot of NOAA<a target="_blank" rel="noopener noreferrer nofollow" href="https://nwcc-apps.sc.egov.usda.gov/imap/#version=2&amp;elements=&amp;networks=!&amp;states=!&amp;basins=!&amp;hucs=&amp;minElevation=&amp;maxElevation=&amp;elementSelectType=any&amp;activeOnly=true&amp;activeForecastPointsOnly=true&amp;hucLabels=false&amp;hucIdLabels=false&amp;hucParameterLabels=true&amp;stationLabels=&amp;overlays=&amp;hucOverlays=state&amp;basinOpacity=100&amp;basinNoDataOpacity=100&amp;basemapOpacity=100&amp;maskOpacity=0&amp;mode=data&amp;openSections=dataElement,parameter,date,basin,options,elements,location,networks,baseMaps,overlays,labels&amp;controlsOpen=true&amp;popup=&amp;popupMulti=&amp;popupBasin=&amp;base=esriWgc&amp;displayType=basin&amp;basinType=6&amp;dataElement=WTEQ&amp;depth=-8&amp;parameter=PCTMED&amp;frequency=DAILY&amp;duration=I&amp;customDuration=&amp;dayPart=E&amp;monthPart=E&amp;forecastPubDay=1&amp;forecastExceedance=50&amp;useMixedPast=true&amp;seqColor=2&amp;divColor=7&amp;scaleType=D&amp;scaleMin=&amp;scaleMax=&amp;referencePeriodType=POR&amp;referenceBegin=1991&amp;referenceEnd=2020&amp;minimumYears=20&amp;hucAssociations=true&amp;relativeDate=-4&amp;lat=41.191&amp;lon=-108.971&amp;zoom=5.5">Interactive Map at this link here</a><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-17 085846-1765987778263.png">So what would help?

Unseasonably warm temperatures are continuing to dominate much of the western United States as an area of high pressure is keeping the jet stream north, which is helping to lock in the warm air!

Denver and Albuquerque normally see highs in the 40s, but will be digging into the 60s!

Record Warmth Out West Continues

It's been a cold start to the week for millions! Areas around the Great Lakes and Ohio River Valley took the most recent Arctic outbreak on the chin, with temperatures plummeting below zero in some instances. On Monday, as winds flipped out of the south, we began to thaw out and most of us are feeling either seasonable or above average by Wednesday. However......The Arctic air isn't getting shoved too far away. This week, we unlock another block of the cold stuff and slide it southward. The good news? It looks like it's not quite as brutal as the last shot.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Web 1-1765981294700.png">A system will emerge out of the Rockies again, moving into much warmer temperatures by Wednesday.

Wednesday night will be the rudest, while Thursday night will likely be the coldest, but should see the winds subsiding. Bismarck, the usual poster child for nasty cold, will only top out in the single digits Thursday afternoon.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Web 2-1765981555057.png">Like a trampoline, temperatures rebound the following day for most.
