Temperatures stay well below normal
Early-week highs across much of Ohio are expected to hover in the upper 20s to low 30s, with nighttime lows dipping into the teens and low 20s, keeping roads and sidewalks prone to refreezing after any precipitation. Long-term January norms for cities such as Dayton and Columbus point to daytime readings near 35°F and sub‑freezing nights, and this pattern is set to hold as the new week begins.
Wintry mix and slick travel
Model-based climatology for early January in Ohio shows frequent light snow events, occasional light freezing rain, and many overcast days, a combination that can quickly create slick spots even when totals are modest. With a very cold air mass lodged over the broader Ohio Valley to start January, any passing disturbance could wring out bursts of snow or freezing drizzle, especially in eastern and central parts of the state.
Regional differences across the state
The eastern half of Ohio, including areas downwind of Lake Erie, faces the highest odds of light snow or snow showers early in the week as cold, moist air flows over the lake and low pressure tracks nearby. Farther west, toward cities such as Dayton and Cincinnati, forecasters expect more breaks of clouds and some sun but still bitter air, keeping wind chills in the teens at times.
Commuters urged to use caution
Transportation officials typically see an uptick in minor crashes during these early‑week setups, when roads can appear merely wet but hide patches of ice after repeated thaw‑and‑refreeze cycles. Drivers are being urged to allow extra time, lower speeds, and give plow trucks and salt crews room to work as Ohio navigates what is shaping up to be a characteristically harsh start to the new year.
