First Big Frost Set To Hit Midwest Friday, Temps Dropping Into 30s

A sharp cold snap will sweep across the Midwest and Mid-Atlantic early Friday, pushing temperatures down to the low 30s. Weather watchers warn this first major frost stretches from Indiana to western Virginia, cutting through Michigan, Ohio, Pennsylvania, and Kentucky.

After this week's rain moves out, a strong high-pressure system takes over. The mix of clear night skies and still air creates perfect frost conditions, with rural spots getting the worst of it.

The mercury will sink to 35°F in South Bend. Fort Wayne should see 34°F, while Ann Arbor drops to a frosty 33°F - marking the end of growing time in southern Michigan. Cleveland and Columbus need to brace for 35-36°F, Pittsburgh will hit 36°F, and Blacksburg might shiver at 34°F.

This cold blast arrives seven days behind its usual schedule. Most years, the first freeze strikes between October 13 and 19.

Weather officials stress the need to shield tender plants and wrap up exposed pipes. Early risers should set their alarms a bit earlier to deal with icy car windows Friday morning.

The chill won't last long. Bright sun will push readings up into the 50s and 60s by afternoon. The weekend brings milder air and clear skies through Sunday.

This frost signals winter's approach. Next week might bring more icy nights as temperatures flirt with freezing across the Midwest and mountain areas.

Friday's dawn could bring thick patches of fog. Pet owners must check their outdoor animals have warm spots to sleep as the night turns cold.
