Powerful El Niño Could Bring More Snow and Ice to Texas, Illinois, Ohio and Pennsylvania This Winter if Cold Air Meets Southern Storms

CHICAGO, IL — As a powerful El Niño continues to develop in the Pacific Ocean, many Americans are wondering whether the upcoming winter of 2026 to 2027 could turn out snowier than usual. An early, unofficial outlook suggests that a strengthened southern storm track may send more systems across the southern United States this winter. If enough cold air is in place when those storms arrive, portions of the South, Plains, Midwest, and East could see more chances for snow and ice.

How El Niño Shapes Winter Storm Tracks

El Niño is a climate pattern marked by warmer than normal ocean waters across the central and eastern equatorial Pacific. During strong events, it tends to energize the subtropical jet stream, steering a steady flow of moisture-rich storm systems across the southern half of the country.

This often leads to a wetter winter across the Gulf Coast, Southern Plains, and Southeast. Whether that moisture falls as rain or snow depends on how much cold air is available when each storm moves through.

Areas Highlighted for Possible Snowier Conditions

The early outlook map highlights a broad area stretching from the Northern Plains through the Midwest and into the Northeast as regions that could see more winter weather opportunities. States such as Minnesota, Iowa, Illinois, Indiana, Ohio, and Pennsylvania fall within this zone.

The outlook also extends winter weather potential farther south into Texas, Oklahoma, Arkansas, Tennessee, and parts of the Deep South, including Mississippi, Alabama, and Georgia. Snow and ice in these southern areas would depend heavily on well-timed cold air outbreaks.

Warmer and Drier Signal for the West

In contrast, the map shows a much warmer signal across the western United States, including California, Nevada, Oregon, Washington, Arizona, and Utah. Parts of the Rockies and Northern Plains fall in a transition zone between the warmer West and the colder central and eastern states.

Strong El Niño winters have historically brought milder conditions to the northern tier of the country at times, so regional outcomes may differ from this early outlook.

Timing of Cold Air Will Be the Key

The most important factor will be the position of the jet stream and whether cold air can line up with the increased moisture at the right time. A stormy pattern alone does not guarantee snow. If storms arrive while temperatures are too warm, precipitation will fall as rain instead.

Ice storms are also a concern in winters where shallow layers of cold air sit near the ground beneath warmer air above, a setup that can produce freezing rain and sleet across the South and Mid-South.

Early Outlook, Not an Official Forecast

This projection is an early outlook and not an official forecast. Seasonal patterns can shift as winter approaches, and regional details are likely to change. Official seasonal outlooks from the Climate Prediction Center will provide updated guidance in the coming months.

El Niño alone does not guarantee a snowy winter, but it can create an active and interesting setup worth watching.

Preparing for Winter Weather

Residents in areas that rarely see snow should consider preparing early, including checking heating systems, protecting pipes, and assembling emergency kits for possible ice storms or power outages.
