The winter of 2026-27 could look dramatically different from anything the United States has experienced in recent years, with a rapidly strengthening El Niño potentially reshaping storm tracks, flooding risks, snowfall patterns and even the threat of winter tornado outbreaks from California to the East Coast.
Meteorologist Max Schuster, host of the Max Velocity – Severe Weather Center YouTube channel, said unusually warm Pacific Ocean temperatures are developing so quickly that the coming El Niño could eventually rival some of the strongest events on record, including the major episodes associated with the winters of 1997-98 and 2015-16.
If those trends continue, Schuster believes parts of the South could face an unusually active storm season, while northern states may spend long stretches warmer and drier than normal before being hit by sharp Arctic outbreaks.
A Potentially Historic El Niño Is Taking Shape
Schuster said the foundation of his forecast is the El Niño-Southern Oscillation, or ENSO, which describes changing ocean and atmospheric conditions across the tropical Pacific.
During El Niño, warmer-than-normal Pacific waters tend to strengthen the southern branch of the jet stream, often sending more storms across California, the southern United States and the Gulf Coast while making much of the northern tier milder and drier.
La Niña generally produces the opposite pattern, with cooler Pacific waters favoring a more northerly storm track and greater opportunities for cold and snow across the northern United States.
This year, however, Schuster said the developing El Niño may become so strong that traditional comparisons have limited value.
Meteorologists often use 1997-98 and 2015-16 as benchmarks for powerful El Niño events, but Schuster said current ocean trends raise the possibility that those years may represent the lower end of what develops rather than the upper limit.
He stressed that the exact placement of the warmest Pacific water will matter almost as much as the overall strength of El Niño, because two similarly powerful events can produce very different winters.
That uncertainty is important. A historically strong El Niño does not automatically create one specific weather outcome, and Schuster repeatedly made clear that small changes in the Pacific pattern could substantially alter where storms ultimately track.
California And The South Could Become Storm Magnets
Schuster pointed to 1997-98 as an example of an El Niño in which the warmest Pacific anomalies were concentrated closer to South America, helping create a powerful storm track toward the West Coast.
California was repeatedly hit by Pacific storms during that winter, while the subtropical jet remained active across the southern United States.
By comparison, the 2015-16 event had the warmest anomalies displaced farther west, which changed the atmospheric pattern and helped push storms differently across the country.
Schuster believes the 2026-27 winter could again feature a very active subtropical jet, with above-average precipitation favored across the southern tier.
Texas, the Gulf Coast and possibly California are among the regions he expects to have the greatest potential for repeated rain and flooding.
California and the Desert Southwest could face what he described as a “relentless barrage” of atmospheric rivers if the Pacific setup becomes favorable, bringing heavy low-elevation rain and potentially enormous snowfall totals in the Sierra Nevada.
Meanwhile, parts of the Pacific Northwest may actually finish drier than average if the main storm track remains displaced farther south.
Northern States Could See Major Temperature Whiplash
For temperatures, Schuster expects much of the Pacific Northwest, northern Plains, Great Lakes and Northeast to average warmer than normal over the winter.
That does not mean those areas would avoid severe cold.
Schuster said powerful El Niño events can increase the possibility of sudden stratospheric warming events, which can weaken or disrupt the polar vortex and allow Arctic air to plunge southward.
As a result, places that spend weeks in mild weather could suddenly experience severe cold.
He described a broad zone stretching from the Pacific Northwest through the northern Plains and Upper Midwest as a region of potential “temperature whiplash,” with long stretches of relatively mild, snowless conditions interrupted by intense subzero outbreaks.
That could produce a winter that feels inconsistent rather than simply warm.
A city might run above normal for much of December or January, for example, but still experience one or two punishing cold waves that dominate how residents remember the season.
Across Texas and the Deep South, Schuster expects temperatures closer to average or even slightly below average, not necessarily because of frequent Arctic outbreaks but because persistent clouds, rain and storm systems could suppress daytime temperatures.
Gulf Coast Could Face An Active Severe Weather Winter
One of Schuster’s strongest concerns is winter severe weather.
He said a powerful El Niño can push the subtropical jet far enough south and make it active enough that the traditional winter tornado threat shifts toward the Gulf Coast.
His highest-risk corridor currently extends from coastal Texas through Louisiana, Alabama, southern Tennessee and Georgia.
Those areas could see conditions supportive of severe squall lines and potentially significant tornado outbreaks during the winter months.
A broader zone stretching from eastern Texas through much of the Mississippi Valley, Florida and the coastal Carolinas could also experience frequent severe-weather episodes.
Schuster said the severe threat farther north into the broader Southeast and Carolinas will depend heavily on how far warm, humid Gulf air can advance before interacting with the jet stream.
This part of the forecast deserves attention because winter severe weather can be especially dangerous when people are less prepared for tornadoes than they might be during spring. A strong southern storm track combined with Gulf moisture can create violent weather even during months normally associated with snow and cold.
Northeast Could Swing Between Rain And Major Snowstorms
The Northeast remains one of Schuster’s biggest wildcards.
During milder stretches, he expects many storm systems to produce rain rather than snow because temperatures may simply be too warm.
But if a disruption of the polar vortex happens at the same time that a moisture-rich storm moves north along the subtropical jet, the result could be dramatically different.
Schuster said that kind of timing could create the setup for a major or even historic nor’easter.
The Ohio Valley, Midwest and Northeast therefore fall into what he called a zone of “precipitation type chaos,” where small differences in temperature could determine whether a particular storm produces rain, ice or heavy snow.
That uncertainty makes snowfall forecasting especially difficult this far ahead.
Rather than pretending otherwise, Schuster displayed a snowfall outlook that was essentially left blank, acknowledging that he does not yet know which regions will end up with the greatest totals.
More precise snowfall projections, he said, will have to wait until the El Niño pattern becomes better established and forecasters can see how other atmospheric drivers begin interacting with it.
The North Could Face A Snow Drought
Although individual Arctic blasts and snowstorms will still occur, Schuster believes parts of the northern United States could finish the season with below-average snowfall.
The Pacific Northwest, northern Plains, Upper Midwest and perhaps portions of the Great Lakes could experience prolonged periods in which storm systems simply do not line up with enough sustained cold air.
That would be a significant reversal from the pattern many people associate with a typical northern winter.
At the same time, the southern half of the country could experience a much busier season of rain, flooding and severe storms.
The contrast is one of the central themes of Schuster’s outlook: the places normally associated with persistent cold may spend much of the season mild, while traditionally warmer regions repeatedly find themselves beneath the most active storm track.
Schuster Says This Winter Could Be Studied For Years
Schuster cautioned that forecasting a winter months in advance comes with substantial uncertainty, particularly when the Pacific itself is changing so quickly.
The strength of El Niño still has to be established, and the location of the warmest water will help determine how the jet stream ultimately behaves.
Even so, he believes the broad pattern is unusual enough that the coming winter deserves close attention.
His current forecast favors heavy precipitation and flooding risks across parts of California and the southern United States, enhanced winter severe weather along the Gulf Coast, warmer average conditions across much of the northern tier and a chance for sudden Arctic outbreaks that could occasionally turn otherwise mild regions sharply colder.
The biggest unknown may be where those cold-air intrusions collide with the storm track.
If they meet over the Midwest or Northeast at the right time, some areas could still experience major snowstorms even during a winter that averages warmer than normal.
Schuster’s broader message is that the 2026-27 season may not fit neatly into familiar categories such as “warm winter” or “snowy winter.” Instead, it could become a season of sharp contrasts, with flooding, severe thunderstorms, snow droughts, Arctic plunges and occasional major winter storms all appearing within the same El Niño-driven pattern.
