Warming up early in the work week, when will we see rain return to the area?

Temperatures warming up to around 70 degrees around the Miami Valley to wrap up the weekend with lots of sunshine. Overnight will be mostly clear, quiet, with a low of 50 degrees. Tomorrow another day full of sunshine with highs in the mid 70s. We will see highs in the mid 70s Tuesday, but a cold front will move through going into Wednesday. We will see those highs drop into the upper 60s on Wednesday with partly cloudy skies. Warming back to the 70s by Friday as a low pressure moves in, bringing shower and storm chances over the weekend, beginning Saturday afternoon, and continuing on Sunday. Highs Saturday in the upper 70s, then cooling to 70 on Sunday.
