Nashville, TN – Northern Tennessee could be in for a snowier winter than usual, as the 2025-26 Winter Weather Outlook warns of elevated heavy snow risk and stronger storms between December and February.
According to the National Weather Service (NWS) Climate Prediction Center, weak La Niña conditions are expected to develop this fall, shifting toward a neutral phase by mid-winter. Historically, this climate pattern brings colder air into the Tennessee Valley while steering more storm systems through the region. For northern Tennessee, this raises the potential for heavier-than-normal snowfall totals.
Meteorologists caution that the outlook is preliminary and influenced by short-term climate drivers. Patterns such as the Arctic Oscillation (AO) and Madden-Julian Oscillation (MJO) can dramatically change storm intensity and timing. These shifts could mean quiet stretches punctuated by sudden, disruptive snowstorms.
Even with that uncertainty, the overall setup suggests a higher chance of above-average snowfall across northern Tennessee, including cities such as Clarksville, Cookeville, and the Nashville metro area. Typically, these regions experience a mix of rain and light snow, but this season’s outlook indicates more frequent opportunities for significant snow accumulation.
Past winters with similar setups show the potential range: Some La Niña and neutral winters brought only a handful of snow events, while others produced disruptive storms that closed schools and highways for days. That variability underscores the need to prepare early, regardless of final snowfall numbers.
Travel concerns loom large for residents. Interstates such as I-40, I-65, and I-24 could face closures or hours-long delays during heavy snow or ice events. With January and February historically delivering the strongest systems, forecasters say northern Tennessee commuters and travelers should anticipate winter travel challenges.
The official NWS winter forecast is set for release on October 16, but emergency management officials urge preparation now. That includes servicing heating systems, stocking up on salt and snow shovels, and preparing emergency kits for homes and vehicles. Drivers are advised to carry blankets, food, and water in case of breakdowns or road closures.
