The National Weather Service in Wilmington, OH, has forecasted relatively dry conditions across the regions of Columbus, Cincinnati, and Wilmington for the days ahead, although the possibility of stray showers in the afternoons near and south of the Ohio River remains on the table. According to the latest area forecast discussion, the area will experience this pattern today and Friday, with near-normal temperatures holding steady into the weekend before a slight warmup early next week. Widespread showers and storms are not expected until next workweek.
While the early morning hours might have brought some patchy fog, especially in river valleys and the lower Scioto Valley, this condition was anticipated to lift as the morning progressed. "With the slowing progression of the front (drier air), dewpoints in the upper 60s continue to linger across most of the ILN FA," the National Weather Service noted, though it also mentioned that visibility could be reduced to one quarter of a mile or less at times.
Temperatures are slated to reach the mid to upper 80s today, with northern areas being a tad cooler than the south. Into the evening, the low-end chances for showers should dissipate, making way for mostly clear nights with temperatures dipping into the lower 60s in central Ohio to the upper 60s in the Tri-State area.
For Friday, the script doesn’t veer much from today’s. Dewpoints will continue to hover in the mid to upper 60s, with an afternoon cumulus field expected. "However, in the absence of any notable source of lift or LL/deep-layer shear, the diurnally-driven SHRA coverage should remain quite limited in nature," the National Weather Service indicated. Come the weekend, a high-pressure ridge is set to raise temperature and dewpoint values, with maximum heat index values anticipated to be in the 90s on Saturday, possibly reaching just shy of the 100s on Sunday.
Into the next week, a breakdown of the high-pressure ridge should give way to more widespread shower and thunderstorm activity across the Ohio Valley by Tuesday. Aviation conditions seem mostly favorable across the region, with some potential for morning river valley fog and no significant weather expected over the weekend.
