KANSAS CITY, Mo. — A wetter-than-usual winter may be taking shape on both sides of the country. A September seasonal forecast from the European Centre for Medium-Range Weather Forecasts, or ECMWF, shows a strong wet signal along much of the West Coast and parts of the East Coast for December 2026 through February 2027. Across the central United States, the signal is weaker, but it still leans wetter than average.
That is an outlook for a three-month season, not a forecast for any particular week. It does not mean it will rain every day in California, or that every storm crossing the Plains will turn into snow. What it does offer is an early look at where precipitation may be more likely to run above normal as El Niño influences the winter pattern.
A pronounced wet signal in the West
The Pacific Coast stands out on the ECMWF precipitation map. Northern and central California, Oregon and Washington all show above-normal precipitation, with some of the strongest projected surpluses appearing near the coast. If that pattern holds, the region could see an active run of winter storms.
The wetter signal does not stop at the shoreline. It reaches into parts of Nevada, Arizona and Utah, as well as the southern Rockies. For people following the forecast from city to city, that’s an important distinction: a wet West Coast outlook is also a story about areas farther inland. Storm tracks can carry moisture well beyond the first place a system makes landfall.
California often gets much of its annual precipitation during the cooler months, so even a modest shift in winter storm patterns can matter. Still, a seasonal map cannot tell us whether rain will arrive in regular, manageable rounds or in a handful of much heavier events. Those are very different experiences on the ground, and it is too early to say which one any community might face.
Florida and the Atlantic Coast stand out
The other prominent wet area lies across Florida and the Southeast. On the European model’s map, above-normal precipitation is concentrated around Florida, the eastern Gulf of Mexico and waters off the Southeast coast. The signal also extends through southern Georgia and the Carolinas.
Farther north, the forecast favors wetter conditions along portions of the Atlantic Seaboard, including the Mid-Atlantic and New England. Parts of the Texas Gulf Coast and Louisiana also appear on the wetter side of the outlook.
This broad southern and eastern pattern fits a familiar El Niño tendency: an active storm track across the southern tier of the United States. But familiar does not mean automatic. The exact path of winter storms can shift, and a change of even a relatively small distance can leave one area soaked while another sees much less.
The central states are a closer call
For Kansas City and much of the nation’s interior, the map is less dramatic. The ECMWF outlook suggests a slight lean toward above-normal precipitation across sections of the Plains, Midwest, Great Lakes and Ohio Valley. Kansas, Nebraska, Missouri, Iowa, Illinois, Indiana, Ohio, Michigan and Kentucky are among the states touched by that broader signal.
A slight lean is worth noticing, but it shouldn’t be mistaken for a promise of a particularly stormy winter. The closer a forecast is to average, the more room there is for the final result to land on either side of it. A couple of substantial storms could make a season look wet on paper; long quiet stretches could still separate them.
The type of precipitation is another open question. A warmer-than-normal winter can still produce snow or ice if moisture arrives during a spell of cold air. For residents in the central states, that’s often the detail that matters most—not just how much precipitation falls over three months, but when it falls and what the temperature is at the time.
Some areas lean drier
The forecast is not uniformly wet. Drier-than-average pockets show up in parts of the northern Rockies and Great Basin, including sections of Idaho, Montana and Wyoming. There is also a smaller dry signal near the Tennessee Valley, around northern Alabama and southern Tennessee, and another narrow area near Michigan’s Upper Peninsula.
Southern Arizona and much of northern Mexico appear drier than normal on the map, while parts of the upper Midwest, including Minnesota and the Dakotas, sit closer to average. These details are a reminder that a nationwide winter headline can hide quite a bit of regional variation.
Why El Niño is not the whole forecast
A strong El Niño can have a major influence on winter weather, but it is not a script that every storm must follow. Past El Niño winters have produced different outcomes across the country’s interior, with some areas finishing wetter than average in one winter and drier in another.
That helps explain the contrast in this outlook. The wet signals near parts of the coasts are easier to spot, while the central states show a subtler shift. It would be tempting to read the whole map as a single prediction—“wet winter everywhere”—but that would miss the most useful part of the forecast: the differences in how strong the signal is from one region to the next.
For snow lovers, a wetter winter does not automatically mean a snowier one. It takes both moisture and sufficiently cold air, arriving together. A storm that brings rain to one city could bring snow or freezing rain farther north. Seasonal precipitation outlooks alone cannot settle that question.
What to watch this fall
The ECMWF seasonal forecast will be updated as winter approaches. Each new run may strengthen, weaken or shift the areas that currently favor above-normal precipitation. Forecasters will also have a clearer picture of El Niño’s development and how other atmospheric patterns are shaping up.
For now, the main takeaway is straightforward: the September outlook places the strongest wet signals along parts of the West Coast and the eastern and southeastern United States, while much of the central U.S. leans only slightly wetter. It is an early heads-up, not a storm warning. The forecasts that matter for a specific trip, school day or winter weather event will come much closer to the date.
