Idaho – Rain and snow chances are expected to increase across Idaho during the January 7–13 period, according to the latest federal weather outlook, raising the potential for winter travel impacts across the state.
According to the National Weather Service Climate Prediction Center, Idaho is included in a region forecast for near- to above-normal precipitation during the 8–14 day window. In mid-January, this pattern typically favors snow across higher elevations and mountain valleys, with rain or mixed precipitation possible in lower elevations during milder periods.
Most of Idaho falls within the 33–50% probability range for above-normal precipitation, indicating an increased likelihood of multiple weather systems rather than a single storm. Central and northern Idaho, including the Sawtooth Range, Bitterroots, and Clearwater Mountains, are more likely to see accumulating snow, while southern Idaho valleys may experience rain transitioning to snow as colder air moves in.
Temperature outlooks for the same timeframe indicate near-normal temperatures statewide. This setup supports snow accumulation in higher terrain and increases the risk of refreezing on untreated roads, bridges, and mountain passes, particularly overnight and during early morning hours following any melting.
For commuters, freight operators, and travelers, the developing pattern may lead to slick roads, reduced visibility, and travel delays. Major corridors including Interstate 84, Interstate 90, U.S. 20, U.S. 26, and U.S. 95 may be impacted during active weather periods, especially through mountain passes and canyon routes.
Forecasters emphasize that 8–14 day outlooks reflect probability trends, not specific precipitation totals or storm timing. Residents are encouraged to monitor daily forecasts and updates from local National Weather Service offices and the Idaho Transportation Department as the period approaches.
No winter storm watches or advisories are currently in effect based solely on this outlook, but the signal supports increased awareness for rain and snow impacts during the second week of January.
