Clouds return overnight, with showers arriving before morning, Storm Center 7 Chief Meteorologist Jamie Simpson said.
Showers and some rumbles of thunder are expected through the morning on Friday, he said, adding it "looks like the bulk of the rain arrives around 4 or 5 a.m. with the potential for the steadiest and heaviest rain to coincide with the commute."
Thunder and lightning also are most likely during the morning commute, Simpson said. Temperatures will rise into the lower 60s by late morning, then hold steady the rest of the day."
Clouds should give way to a little late-day sun," Simpson said. adding it will be breezy after the rain exits with winds in the 20-25 mph range.
Skies will clear a bit in the evening, then more clouds arrive toward Saturday morning as temperatures drop back into the mid-40s.
There is a chance Saturday for a light passing shower, more likely in the morning. Afternoon highs will be in the mid- to upper 60s.
Skies will be partly sunny on Sunday with morning temperatures starting off in the mid-40s and ending up in the mid- to upper 60s in the afternoon.

On Monday, the day will start dry, but showers and thunderstorms will arrive; the day will get wetter as time goes on. Morning temperatures will start in the mid-40s and climb into the mid-60s for afternoon highs.
On Tuesday, showers and thunderstorms are possible at any time throughout the day."Rain looks to be more widespread and frequent Tuesday than Wednesday," Simpson said.Morning lows will be in the lower 50s with afternoon highs near 70.
A system will stall over the Ohio Valley all of the workweek next week, Simpson said.
