Skies will remain partly cloudy overnight, but there is a chance for some storms to develop, Storm Center 7 Chief Meteorologist Eric Elwell said.
Overnight: Skies will be partly cloudy with scattered storms possible after 3 a.m. in mainly the western part of the Miami Valley. It will stay warm and muggy with lows only in the lower 70s by morning.
Friday: An Excessive Heat Warning goes into effect at 10 a.m. Friday through 8 p.m. Saturday for Montgomery County issued by the National Weather Service. A Heat Advisory will be in effect from 10 a.m. Friday through 8 p.m. Saturday for Auglaize, Butler, Champaign, Clark, Clinton, Darke, Greene, Logan, Mercer, Miami, Preble, Shelby and Warren counties in Ohio and Wayne and Randolph counties in Indiana. This means it could feel like 100 to 104 degrees outside due to the high temperatures and humidity. On and off clouds are expected along with the chance for thunderstorms. Outside of the storms, temperatures will reach into the lower 90s and the heat index will top 100 degrees at times.
Saturday: More scattered storms are possible with the Excessive Heat Warning and Heat Advisory still in effect through 8 p.m. Outside of storms, it will be very hot and humid with temperatures in the lower 90s and the heat index over 100 degrees.
Sunday: Another hot and muggy day is expected with scattered storms possible, especially in the late afternoon and evening. Highs will be back in the lower 90s.
Monday: Storms will be more numerous with mostly cloudy skies. Highs will still top out near 90 degrees.
