Columbus, OH – A sustained cold pattern will settle across the Ohio Valley starting Thursday, April 30, pushing temperatures 40% to 60% below normal and immediately slowing travel along I-70, I-71, and I-75 during peak commute hours.
According to the National Weather Service, a cold air mass dropping out of the Upper Midwest will expand across Ohio, Kentucky, West Virginia, and western Pennsylvania through Tuesday, May 6. Highs in Columbus, Cincinnati, Louisville, Lexington, and Charleston will struggle to reach the low to mid-50s, while overnight lows dip into the upper 30s to low 40s.
Morning commuters will see the greatest impacts, especially along I-71 between Cincinnati and Columbus and I-64 from Louisville into West Virginia. Intermittent light rain and damp pavement may reduce visibility and extend drive times, particularly during early hours. While overall precipitation trends remain near normal, brief showers could create localized slowdowns.
In more rural and sheltered areas of Kentucky, southern Ohio, and West Virginia, overnight temperatures may approach the upper 30s, raising the risk of patchy frost. This could affect early planting and sensitive vegetation, especially in valleys where colder air settles.
Utilities across the region may experience increased demand as heating systems run longer than typical for early May. Light winds combined with cooler air will reinforce the chill, particularly during pre-dawn hours when temperatures are lowest.
This colder-than-normal pattern is expected to persist through May 6, with gradual warming possible afterward. Additional updates may refine frost risk and precipitation coverage as the system evolves across the Ohio Valley.
