Ohio’s spring warmth is already shifting gears, and roads across southwest Ohio could turn slick fast by late Sunday afternoon as showers build into thunderstorms.
According to the National Weather Service in Wilmington, dry and calm conditions hold through today, but changes begin after 2 p.m. Sunday when scattered showers develop. Storm chances climb to 40% through late afternoon, then surge to 80% Sunday night as a stronger system pushes in. Thunderstorms may produce bursts of heavy rain and reduced visibility, especially along U.S. Route 68 and I-71 near Wilmington.
Temperatures spike to near 81°F Sunday, giving the air a humid, almost summer-like feel before storms take over. Winds may gust near 29 mph during the afternoon, adding instability. By Sunday night, steady rain and embedded thunder could slow travel and create ponding on low-lying roads. Plan extra time if driving after sunset.
Monday brings a quick reset. Skies clear with sunshine returning, but cooler air follows with highs near 49°F. That drop raises a subtle risk: wet pavement early could dry, then refreeze late night as lows dip near 30°F. Watch for isolated slick spots on bridges by early Tuesday.
Looking ahead to Tuesday, March 24, quieter weather returns with sunshine and highs in the mid-50s. Midweek stays mild and mostly cloudy, reinforcing that spring is settling in.
