The mercury officially hit 91 degrees Tuesday for the first time since Sept. 11, 2013, and some will likely see another 90-degree day Wednesday, Storm Center 7 Chief Meteorologist Jamie Simpson said Tuesday night.
Tuesday's high temp was recorded at Dayton International Airport at 2:46 p.m. The high humidity will keep it feeling even warmer. The heat index will be in the mid- to upper 90s through early evening.
Tonight will be warm and sticky, with temperatures in the low-70s.
Wednesday will be hot and humid again. Highs will be near 90 -- especially south of I-70, Simpson said.
Showers and storms are expected to arrive far north of Dayton in the late afternoon or early evening, then slowly migrate south through the night.
Thursday will bring more scattered thunderstorms as the heat and humidity continue.
