It will be unseasonable cool this evening and overnight, with temperatures dipping to near the record low.
"We'll drop from the low 70s this afternoon through the 60s this evening and to the lower 50s at sunrise," said Storm 7 Center Chief Meteorologist Jamie Simpson. "The record low Wednesday is 52, which is about what we expect for the Dayton and Springfield areas."
Some areas to the north could see overnight lows in the upper 40s.
Not one, but two records may be set Wednesday. The record for the coolest high temperature is 72, and the high tomorrow may only rebound to about 70 degrees, he said.
Morning sun will give way to afternoon clouds with a few light scattered showers expected in the afternoon, he said. Chances for showers will be better north than south, he said.
Lows will mainly be in the mid-50s Thursday, but some areas will drop to the lower 50s again, he said. Afternoon highs will be in the mid-70s.
Mostly sunny skies will give way to some high clouds later in the day Friday, but the gradual warm up continues. Morning lows will be in the low to mid 50s with afternoon highs in the upper 70s.
Sun and more clouds are expected through the day with a chance of a shower south later in the day Saturday. Most should have a dry day.
Morning lows will be near 60 and afternoon highs will be near 80.
There will be less sun and a better chance for showers Sunday. A few thunderstorms are possible. Highs will be near 80.
