Freeze Warning Issued Across Ohio: Cincinnati and Columbus Brace for First Fall Freeze

Ohio is experiencing its first significant cold snap of the fall season. The National Weather Service (NWS) has issued a freeze warning for large portions of the state, including Cincinnati and Columbus, as temperatures are forecast to drop below freezing overnight on Friday, October 24.

The warning follows Thursday’s early frost advisory that greeted residents with icy windshields and brisk morning air. It marks the first time this season that both cities are expected to experience widespread freezing conditions.

Freeze Warning Details for Cincinnati and Columbus

According to the National Weather Service, the freeze warning will be in effect from 1 AM to 9 AM EDT on Friday. Overnight lows are projected to fall between 30°F and 34°F, signaling a full freeze in some suburbs and rural areas surrounding both metropolitan zones.

In Cincinnati, Thursday started with temperatures in the mid-30s and clear skies, creating ideal conditions for frost formation. Daytime highs hovered near 59°F, with calm winds from the west. As skies remain clear tonight and winds subside, cold air will settle in, creating near-perfect conditions for a freeze to form across southwestern Ohio.

Columbus, meanwhile, saw slightly cooler conditions throughout Thursday, with afternoon highs around 56°F and light westerly winds. The forecast calls for increasing clouds by evening, followed by clear skies overnight. Temperatures are expected to drop to the lower 30s, flirting with sub-freezing marks in several neighborhoods.

The NWS warns residents that unprotected vegetation, outdoor water lines, and sensitive plants could be damaged or destroyed. People are urged to bring potted plants indoors, cover garden beds, and ensure that pets are kept warm overnight.

Weekend Weather Outlook Across Ohio

Following the freeze warning, the weekend is expected to remain chilly but pleasant. Saturday will bring mostly sunny skies and highs in the low 60s for Cincinnati and upper 50s for Columbus. Sunday will be partly cloudy with a slight chance of light rain late in the evening.

For gardeners and homeowners, this freeze marks a seasonal turning point — the official end of the growing season for much of central and southern Ohio. Meteorologists note that temperatures will stay below average through early next week before moderating by midweek.

What Residents Should Do During a Freeze Warning

The National Weather Service and local emergency management offices emphasize basic precautions during freeze conditions. Covering outdoor plants, insulating exposed pipes, and avoiding use of outdoor water spigots are simple but essential steps to prevent damage.

Residents should also check on elderly neighbors or anyone without adequate heating, as sudden temperature drops can pose health risks. Pets should be kept indoors overnight, as frost conditions can be dangerous for animals left outside for extended periods.

With the freeze warning taking effect early Friday morning, Ohioans are being urged to prepare now for the first true taste of winter weather.
