CINCINNATI (WXIX) - A First Alert Weather Day remains in effect through Friday morning as heat, humidity and a few rounds of thunderstorms continue across the Tri-State. Most communities will stay dry through the evening, but any isolated storm that develops could produce brief heavy rain and gusty winds. Heat indices will climb into the 90s thanks to dew points near 70 degrees. The greater concern arrives overnight and early Friday morning as a cold front moves through the area.
