El Niño Forecast Promises Dramatic Snowfall Shifts Across U.S.

A significant shift in winter weather patterns is anticipated across the United States for the 2026-2027 season, driven by a potent El Niño. Meteorologists at AccuWeather predict that 12 states, including California, Nevada, Utah, Arizona, Colorado, New Mexico, Texas, Oklahoma, Kansas, Nebraska, Iowa, and Missouri, are likely to experience snowfall exceeding their average winter totals. This forecast marks a stark contrast to the previous year, where many of these regions saw minimal snow. \n\nConversely, the northern half of the U.S. is projected to face historically lower snow accumulations between October 2026 and April 2027. Parts of at least 30 states, stretching from the Pacific Northwest through the Great Lakes and into New England, are expected to experience warmer and drier air, leading to fewer snowstorms. Major cities like New York, Boston, Philadelphia, Pittsburgh, Buffalo, and Chicago, which received substantial snowfall in the prior year, are forecast to get less than half of their typical amounts. \n\nAccuWeather Senior Meteorologist Chad Merrill stated that the primary storm track is expected to shift across the southern U.S., particularly in the early part of winter, leaving many areas in the Plains with little snow. This dramatic alteration in winter weather is attributed to global weather patterns being influenced by El Niño, a natural phenomenon characterized by the warming of the Pacific Ocean. \n\nAccording to AccuWeather Long-Range Expert Paul Pastelok, the current El Niño event has the potential to be one of the strongest on record, possibly surpassing those of 1982-83 and 1997-98. Pacific temperatures are predicted to rise significantly, pushing the jet stream further south. This southward shift will direct moisture and storms toward southern states that typically receive little winter precipitation. \n\nCities such as Las Vegas, Nevada, and Albuquerque, New Mexico, are now expected to be in zones experiencing above-average snowfall. Salt Lake City, Utah, which recorded a record low of 3.7 inches last year, is forecast to receive between 50 and 65 inches this winter, a significant increase from its previous minimal accumulation. Similarly, Denver, Colorado, is predicted to return to its normal snowfall range of 45 to 55 inches after only receiving 27.3 inches last winter. \n\nIn contrast, cities accustomed to heavy snowfall are bracing for milder winters. Boston, which saw nearly 63 inches last year, is now expected to receive only 15 to 30 inches. New York City, which recorded 43 inches, could see as little as 10 to 20 inches. Buffalo, New York, known for its heavy snow, might receive as little as 55 inches, approximately half of its normal winter total. \n\nThe Northeast region as a whole is anticipated to be two to four degrees Fahrenheit warmer than average. Parts of northern Minnesota, Michigan, and Wisconsin could be over five degrees warmer. Pastelok noted that heating demand across the Great Lakes, Ohio Valley, and Northeast is expected to be considerably lower than in the previous year. \n\nHowever, the Southwest, Rocky Mountains, and Gulf Coast regions, including cities like Phoenix, Houston, and New Orleans, are predicted to face an uncharacteristically cold winter. Pastelok cautioned that while below-average snowfall is forecasted for some areas, a single major storm could alter the situation, especially for East Coast cities, particularly in late January and February. The intensity of this El Niño is expected to influence U.S. weather patterns through 2027, potentially contributing to further climate uncertainty into 2028.
