Southwest Ohio residents, especially around the Wilmington region, should be prepared for patchy fog early Sunday morning that may impact road safety. Areas along I-71 and nearby highways could see reduced visibility before conditions improve later in the day. Once the fog lifts, a beautiful stretch of sunny, cooler weather is expected to carry into the week.
Morning Fog Brings Road Hazards
According to the National Weather Service in Wilmington, fog is expected to develop overnight into early Sunday morning, especially in low-lying valleys and rural routes. The fog could make driving conditions hazardous, particularly before 8 a.m.
If you’re planning to travel early:
Drive slowly and cautiously
Use low-beam headlights
Avoid sudden stops or lane changes
Allow extra time for your morning commute
Fog can settle thickest near rivers, farmland, and open fields—common across Clinton County and surrounding areas—so early drivers should remain alert.
Sunshine Returns by Late Morning
Thankfully, the fog won’t last all day. By late morning, skies will clear quickly, leading to a mostly sunny afternoon with a comfortable high near 79°F. Light winds will keep the weather calm, creating a great opportunity for outdoor activities, errands, or just enjoying the fresh air.
Sunday night will be mostly clear, with temperatures cooling down to around 53°F.
Cooler Weather and Clear Skies Continue Into the Week
Starting Monday, the region will experience a refreshing stretch of cooler, dry weather:
Highs will remain in the low 70s
Overnight lows will dip into the upper 40s
No rain or storms are expected through Friday
This cooler pattern is perfect for back-to-school routines, early fall prep, or just enjoying the last days of August without heat or humidity.

The National Weather Service will continue monitoring fog development and will issue advisories if visibility becomes a greater concern. After the fog clears, residents can look forward to a calm and enjoyable weather pattern through the workweek.
