The USA Nationwide Oceanic and Atmospheric Administration (NOAA), some of the trusted meteorology sources on the planet, publishes climate prediction updates every month. Learn on for the official report from NOAA, descriptions, and our takeaways for the place YOU can rating blower pow days this winter.
This can be a take a look at NOAA’s predictions revealed October seventeenth for December 2024 by means of March 2025.
It’s essential to notice that whereas these predictions are based mostly on detailed scientific knowledge, backed by months of sample evaluation and years of analysis, they don’t seem to be exact predictions for particular states. Nevertheless, they’ll provide an actual take a look at what common areas might appear to be this winter. Plus, they’re enjoyable to undergo so what’s the hurt in fantasizing about a number of deep turns this winter? No judgment right here.
Earlier than we discover the present predictions, let’s look at what a few of the difficult phrases imply.

NOAA makes upcoming winter climate predictions for North America based mostly on patterns and knowledge readings within the Pacific Ocean. That is known as the ENSO (El Niño / Southern Oscillation) local weather sample. ENSO refers back to the common local weather patterns within the Pacific Ocean and doesn’t point out an El Niño cycle, regardless of the title. Sure, it’s complicated. From this sample, they’ll measure temperature anomalies which are creating. These predicted cycles are indicated by phrases you’ve probably heard earlier than; El Niño and La Niña.
“El Niño and La Niña signify reverse extremes within the El Niño/Southern Oscillation (ENSO). The ENSO cycle refers back to the coherent and typically very sturdy year-to-year variations in sea-surface temperatures, rainfall, floor air stress, and atmospheric circulation that happen throughout the equatorial Pacific Ocean” – NOAA
- El Niño is characterised by hotter tropical Pacific ocean floor temperatures.
- Sometimes lasts round 9-12 months and is extra frequent, in keeping with NOAA.
- La Niña is characterised by cooler than regular tropical Pacific ocean floor temperatures.
- Sometimes lasts 1-3 years. In keeping with NOAA, durations of both can fluctuate tremendously, even by a matter of years.
Totally different stress methods make up one other key piece to understanding the ENSO cycle.
Low-pressure methods pull air in and are related to El Niño cycles of heat Pacific ocean floor temperatures. This method pulls the Pacific jet stream “south of its impartial place,” in keeping with NOAA, which brings moisture to the southern U.S. and hotter temperatures to the north.
Excessive-pressure methods push air out and are related to La Niña cycles of cooler Pacific ocean floor temperatures. This method pushes the Poplar and Pacific jet streams north, bringing dryer circumstances to the Southern United States, and colder air with above-average precipitation to the north.
La Niña Watch Continues, Fall Emergence Favored at 60% with Odds Rising Nearer to Winter
Our first report on NOAA’s winter 2024/25 predictions got here in July. At that time, fashions indicated a robust 70% likelihood of a La Niña system rising this autumn and carrying into winter. Since then, the possibilities of a La Niña system turning into prevalent in North America have fallen to 60%.
A piece of the official abstract launched on October nineteenth reads:
“A La Niña Watch stays in impact, with La Niña favored to emerge throughout September-November (SON) 2024 (60% likelihood) and is forecast to persist by means of January-March (JFM) 2025. Any La Niña occasion that develops this autumn is favored, nonetheless, to be a weak, short-duration occasion.” – NOAA (10/19/24)
There’s favorability for an autumn emergent La Niña system, nonetheless, these odds have been reducing steadily since July, so chances are high it will likely be a weaker system. As talked about within the data above, La Niña is characterised by a blocking high-pressure system that forces the Pacific and Polar Jet Streams north. This chilly, moisture-laden air then brings cooler temps and extra snow in particular areas just like the Pacific Northwest (PNW) and the East North Central States, (Michigan and its neighbors). However it could additionally push hotter air to locations just like the Southeast and the Central Rockies.
All that is to say {that a} La Niña system, whether or not weak or sturdy, doesn’t imply that your particular space will probably be getting snorkel-deep days anyway, regardless of the frequent narrative that this climate sample means pow for all. So don’t let the declining early-emergent proportion bum you out, because it may work in your favor. It seems that this latest replace is promising for a number of states. Let’s take a look at the Temperature and Precipitation Outlooks beneath to get a greater really feel for particular areas of the USA.
Temperature Outlooks
The Temperature Outlook for December 2024 by means of February 2025 exhibits main change when in comparison with final month within the Northwestern States. NOAA is now calling for below-normal temperatures within the space that stretches from the Canadian border by means of Northern Wyoming, and from the West Coast into central Minnesota.
The majority of those frigid temps is targeted on Washington, northern Idaho and Montana and North Dakota. After all, you can even count on our associates snowboarding in British Columbia and Alberta to see chilly climate as nicely. The remainder of the map has not modified a lot when put next with predictions from September. Southeast Alaska remains to be below-normal temperatures, however as we’ll see within the Precipitation Outlooks, this doesn’t imply snow is a assure.
As we focus our consideration on the Temperature Outlook for the majority of winter, we are able to see that below-normal temperatures have a 33-50% likelihood of prevailing in these Northwestern States, with the sting of these projections transferring barely farther south. The realm labeled as Equal Probabilities additionally strikes farther south. For skiers in Wyoming and most of Colorado and Utah, that is excellent news, as they’re located north of the above-normal temperatures vary.
It’s definitely going to be a really chilly winter for Oregon, Washington, Idaho and Montana. Simply how chilly stays to be seen. As a result of these states have had pretty subpar winters for the final two to a few seasons, it’s a good guess that skiers are able to embrace the storm and (hopefully) the deep days that may include it.
Precipitation Outlooks
Now it’s time for our favourite climate function of all; precipitation! The frozen water from the sky is the explanation we’re right here within the first place. There are a number of drastic adjustments within the Precipitation Outlook for December 2024 by means of February 2025 in comparison with final month. We’re not seeing above-normal precipitation predicted for the Midwest and East Coast through the begin of this ski season. However don’t fear Ice Coasters! There’s nonetheless hope, as is obvious within the map beneath.
The areas with the very best likelihood of above-normal precipitation by means of these months are Northern Idaho, Western Montana, Northwestern Wyoming and Michigan in addition to Northeast Alaska. Many of the legendary snowboarding in AK resides within the Southeast.
Lastly, we come to the Precipitation Outlook for the meat of winter, January by means of March 2025. This projection map exhibits little important change from final month’s replace, with the first alteration being seen within the Midwest and Utah. The Midwest is not favored to see the above-normal precipitation that was beforehand projected, and Northwest Utah has been moved out of the below-normal precipitation vary, with the impacted space now being barely south.
As is frequent in La Niña methods, the PNW (from Central Oregon east by means of Southwest Montana) is favored at 33-50% for above-normal precipitation. And as soon as once more, our sleeper choose for winter 2025 is wanting like Michigan! As we’ve stated up to now, skiers like Mike King and Mike Hornbeck are proof that The Mitten harbors some passionate ski tradition and true expertise. After all, we even have our eye on the East Coast. Vermont’s Inexperienced Mountains had been just lately blasted with a mighty October snowstorm that left over a foot for skiers to take pleasure in, and boy did they get after it. We’re praying to Ullr that our associates out east see a legendary yr.
What the Hell Does This All Imply?
Right here we go once more. What DOES this all imply? It’s truthful to say that whereas the emergent proportion has been dropping, we’re going to guess the farm {that a} La Niña system does certainly seem this winter. Cooling common ocean floor temperatures proceed to be a robust indicator. It may not have arrived but, however it’s probably simply giving us a drawn-out entrance.
We are able to already hear the haters saying, “That is faux information! These projections don’t imply something!” Whereas there’s a splash of validity to that sentiment, the overall developments will probably maintain true; a La Niña winter is coming. If we had been hesitant to say it again in July, we definitely aren’t now.
And in case your neck of the woods isn’t slated to have a hell of a yr, this might a good time to plan that lifetime journey you’ve at all times dreamed about! Use this as motivation to make the daring transfer and head someplace new and thrilling. FREESKIER may even have some in-depth new journey content material debuting quickly that will help you with that call, so keep tuned…
For now, we are going to depart you with our 4 over-the-top predictions for winter 2024/25 –
- The PNW (and a lot of the Northwest) can have a yr. Head to Mount Baker when you’ve been considering of it. After all, going into Western Canada throughout a La Niña winter is at all times an excellent name as nicely. The realm is normally identified for getting numerous heavy snow, with powder mornings turning into cake batter cement snow afternoons earlier than your eyes. Nevertheless, these colder temperatures ought to be sure that dry snow makes its strategy to the western reaches of America this winter. After Idaho and Montana noticed poor winters over the past two years, it’s time for a much-needed refresh.
- Hit the Mitten. That’s proper. Should you’re a Midwest skier searching for an journey that isn’t far and gained’t break the financial institution, head to Michigan. Some true legends of the game have come out of this state, equivalent to Mike Hornbeck, Mike King and Josh Daiek, chatting with how enjoyable the snowboarding will be. Whereas temperatures appear prone to fluctuate, prolific moisture appears possible.
- It is perhaps an excellent yr to ski the east… perhaps. We’re solely throwing that “perhaps” in there to be cautious. BUT, issues definitely look promising for skiers in New Hampshire, Vermont, Upstate New York and Maine. This portion of the nation additionally produces some unimaginable skiers who don’t get their justifiable share of deep fluff. That rarity is a part of what makes an Ice Coast pow day so particular. That being stated, we’d be fairly stoked if all our associates out east received ten (or 100) extra laps in waist-deep snow this yr.
- Central and Southwestern states, don’t quit hope. Colorado and Utah, we’re you. Because the previous saying goes, it ain’t over until it’s over, and it certain as hell isn’t over! No, the forecast doesn’t look promising for these spots, however sleeper storms are by no means out of the realm of chance. Each skier has seen proof of the magic {that a} lake effect-fueled storm can ship for Utah’s Cottonwood Canyons. And who hasn’t heard tales of snow that barrels over your head after a multi-day dump at Wolf Creek in Southern Colorado?
It doesn’t matter what the following few months maintain for you, one other winter making turns of any form is one thing to stay up for. Because the ski season attracts nearer, we’ll be sure you hold you up to date on NOAA predictions and present climate patterns all through North America in order that YOU can line up the ski journey of all ski journeys this winter.

seasonal imply temperatures for a lot of the Contiguous United States (CONUS)
from the Southwest eastward to incorporate a lot of the central U.S. and the entire
japanese CONUS. The most important possibilities (better than 60 %) of above
regular temperatures are forecast for components of the Southwest. There is also an
enhanced chance of above-normal temperatures for northern Alaska.
Beneath-normal temperatures are most certainly for a lot of southern Alaska.The NDJ 2024-2025 precipitation outlook depicts enhanced possibilities of
below-normal seasonal complete precipitation quantities alongside a lot of the southern
tier of the CONUS and for components of southeast Mainland Alaska and Alaska
Panhandle. The best odds of below-normal precipitation (better than 50
%) are forecast for components of the Southwest and Southern Plains. Slight
tilts towards above-normal precipitation is depicted for components of the Pacific
Northwest, northern Rockies, central Nice Lakes, and western and northern
