WILMINGTON, Ohio – A hot start to the workweek will challenge drivers and residents across Clinton County as temperatures rise near 90° Monday, September 15. Heat combined with morning fog could reduce visibility along I-71 and U.S. 68, slowing commuters before conditions clear.
According to the National Weather Service in Wilmington, skies turn sunny by mid-morning Monday with highs reaching 88°. Winds shift east near 6 mph, keeping the region humid into the evening. The agency advises drivers to allow extra travel time Monday morning, especially in low-lying areas where fog lingers.
By Tuesday, conditions remain warm with highs in the upper 80s before a slight cool-down arrives Wednesday. Dry weather will dominate most of the week, but rain chances return by Friday evening. Overnight lows in the upper 50s and lower 60s will provide only brief relief from daytime heat.
Sunny skies Tuesday and Wednesday will favor outdoor events, but prolonged exposure could still bring heat stress for workers and students. Residents should hydrate frequently and check on elderly neighbors as late-summer warmth continues.
The region could see the first measurable showers of the week Friday into Saturday. Though coverage remains spotty, motorists should prepare for slick roadways and reduced visibility if showers develop during peak travel times.
The National Weather Service will issue further updates if rain chances increase heading into next weekend.
