NOAA’s latest long-range outlook points to above-average winter precipitation from Maine to Florida, and independent forecasters warn millions could face major snow or ice storms.
The National Oceanic and Atmospheric Administration’s September 17 seasonal outlook shows a major shift in heavy precipitation bands for December 2026 through February 2027. The map signals a growing chance of above-average rain or snow along the entire U.S. East Coast, stretching into Alabama, Mississippi, Louisiana, and Texas, with California also expected to see elevated precipitation.
Several independent forecasters say at least 19 states should brace for a potential blockbuster storm season. The Daily Mail reported the updated outlook accounts for El Niño conditions that are reshaping where winter moisture is likely to fall.
El Niño forms when the Pacific Ocean runs significantly warmer than usual. That pattern can push the jet stream farther south and send more moisture into the southern half of the country and up the East Coast.
The strongest chances of heavy rain or snow on the NOAA map run through northern Florida, Georgia, southern Alabama and Mississippi, South Carolina, North Carolina, and eastern Virginia.
Meteorologist Ryan Hall said a stretch of the South, Southeast, and Mid-Atlantic could sit in the greatest danger this winter. That corridor includes Oklahoma, Arkansas, Tennessee, Kentucky, the Appalachians, the Carolinas, and Virginia.
Hall updated his winter forecast after NOAA’s September 17 outlook and laid out the change in a September 19 YouTube briefing.
"On my map, this is the winter storm battleground, and this is actually where my forecast has changed the most. I'm now a lot more confident than I was a few weeks ago that somebody in this corridor is going to get a big snowstorm or a big ice storm this winter."
He still called the Northeast outlook difficult to pin down. Hall pointed to Washington, D.C., Baltimore, Philadelphia, New York, and Boston as cities inside a wetter pattern that now extends into New England.
"It's still a tricky forecast. [Washington] DC, Baltimore, Philly, New York, Boston. I still like the storm signal and the new outlook runs that wet pattern way up into New England."
On the question residents care about most, rain or snow, Hall refused to force a firm call.
"I think there's going to be plenty of chances over here. But that still doesn't answer the thing that everybody actually wants to know: rain or snow. And I'm going to be sticking with that same coin flip."
That uncertainty matters because past El Niño winters have produced wildly different results in the same cities. The 1997-98 event left Washington, D.C., with only 0.1 inches of snow. The 2009-10 El Niño winter dropped more than 56 inches on the capital.
Readers tracking the larger climate pattern will recognize the same driver behind recent coverage of a record-shattering El Niño and shifting U.S. moisture.
Independent forecaster Direct Weather, run by self-taught forecaster Ashton Ballou, has taken a more bullish stance on snow along the East Coast. The group bases its outlook on public ocean-temperature readings and NOAA seasonal computer models.
In a September 15 prediction, Direct Weather said it expects higher snow totals on the western side of frequent Northeast storms.
"We do expect nor'easters to be a frequent event this year up the East Coast, and these do tend to be snow producing at least for somebody depending on where that low [pressure system] is located."
The same outfit warned that storms could keep coming for months.
"Somebody on the western edge of that storm would be likely getting major amounts of snowfall. We do expect those to be battering us all fall and wintertime long."
California’s above-average precipitation signal would likely mean feet of snow in the Sierra Nevada and other high-altitude areas out west, according to the same long-range picture.
The moisture shift fits the broader pattern described when U.S. winter moisture shifts south under a strengthening El Niño.
Not every long-range shop is selling a snow-heavy winter. AccuWeather has sounded more skeptical that the season will set snow records and has said 2027 may instead set marks for a lack of snow.
Lead long-range expert Paul Pastelok framed the risk around water, not powder.
"It may be more about rainfall this year, coastal flooding, and rivers rising. That’s something you talk more about during the spring, but it could be the opposite this year."
That split leaves the public with two live scenarios under the same El Niño setup: frequent snow-and-ice threats along Hall’s battleground corridor, or a wetter season of rain, coastal flooding, and rising rivers that never fully turns to snow in the big Northeast cities.
Hall himself noted that earlier El Niño winters did not all produce the same snow season, which is why he is holding the rain-versus-snow call as a coin flip even while raising confidence in storm frequency.
The same Pacific warmth tied to this winter outlook has already reshaped other seasonal calls, including a reduced Atlantic hurricane outlook as a potential record-setting El Niño builds.
From December 2026 through February 2027, the NOAA model focuses attention on a long East Coast swath from southern Maine to the tip of Florida. The southern tier into Texas sits inside the same above-average precipitation signal.
Hall’s highest-concern inland belt runs through Oklahoma, Arkansas, Tennessee, Kentucky, the Appalachians, the Carolinas, and Virginia. The Northeast list he flagged for the coin-flip call includes Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, and Maryland.
File references in the reporting also noted whiteout conditions seen frequently from the West Coast to the Great Lakes during the 2025-2026 winter season, and a January 2026 image of cold and snow in New York City, reminders of how fast a wet pattern can turn disruptive when temperatures cooperate.
Polar-vortex swings can still scramble any early map, a point underscored in recent analysis of how a weakening polar vortex and super El Niño can cloud U.S. winter forecasts.
None of the named forecasters claimed certainty on total snowfall for the major coastal cities. NOAA’s product is a precipitation outlook, not a finished snow total. Direct Weather is leaning into repeated nor’easters and western-edge snow. AccuWeather is warning that rainfall, coastal flooding, and river rises may dominate instead. Hall is confident someone in the South-to-Mid-Atlantic corridor takes a major snow or ice hit, while keeping the big-city rain-or-snow question open.
Millions of residents, school districts, and road crews from New England through the Deep South now have months, not days, to watch the same signal tighten. Early seasonal maps do not clear driveways. They do tell taxpayers and local officials where the next expensive winter mess is most likely to set up.
When federal outlooks and private forecasters both raise storm flags this far out, the smart move is preparation, not panic, and not another winter caught flat-footed by moisture everyone saw coming.
