ST. LOUIS, Mo. — Winter may arrive sooner and hit harder across Kentucky and eastern Missouri this year, as La Niña brings a stormy, moisture-packed weather pattern expected to stick around well into February 2026. According to both NOAA and the Farmers’ Almanac, residents should prepare for a relentless cycle of cold snaps, snowstorms, and freezing rain.
The season’s simple forecast?
“Chill, Snow, Repeat.”
Early Snow and Icy Conditions on the Way
Forecasters warn that northern areas of both states—especially those near St. Louis and Louisville—may see the first snowfall as early as late September, well ahead of schedule.
NOAA’s Climate Prediction Center says La Niña will shift storm systems straight into the Ohio Valley and lower Midwest, increasing the risk of:
Heavy snow north of St. Louis and Louisville
Freezing rain and sleet in central Kentucky and southeastern Missouri
Icy roads and power outages, particularly in rural regions
This combination of moisture and Arctic air will make for a difficult winter, not just in terms of cold, but also in commuting, travel, and storm recovery.
Major Travel Routes Under Threat
Several highways and interstates are expected to see serious winter hazards, including:
I-64, from St. Louis to Lexington
I-70, impacting central Missouri
I-55, stretching from eastern Missouri into western Kentucky
Sudden snow squalls, slick black ice, and quickly changing weather could cause frequent traffic accidents, backups, and closures.
Air travelers aren’t in the clear either—Louisville Muhammad Ali International Airport and St. Louis Lambert International Airport may experience flight delays and cancellations, particularly during major snow or ice events.
Rural Communities Face Power Outage Risk
In rural Kentucky, ice storms remain a major concern. Freezing rain can coat trees and power lines, leading to:
Widespread outages
Blocked rural roads
Limited access to emergency services
Residents in these areas are being urged to prepare early, especially by gathering supplies, securing backup heat, and checking generators.
Long Winter Ahead
Both NOAA and the Farmers’ Almanac agree—La Niña will likely linger through February, keeping conditions colder and stormier than normal for much of Kentucky and eastern Missouri. With frequent freeze-thaw cycles and a mix of snow and rain, roads may stay hazardous and school or work delays may be common well into the new year.
