There are a lot of quirks about Cincinnati. First, the airport is actually across the Ohio River in Kentucky. Next, the radar terminal for the area is actually to the north, in Wilmington, because the WFO there services Columbus, Dayton and Springfield, as well. It begs the question: what exactly IS Cincinnati?

At 352PM, ET, Cincinnati was reporting a temperature of 74 degrees with mostly cloudy skies. The clouds were patchy or much of the tri-state region, with clearer skies at other nearby sites. Low pressure over the northern Plains is entangled with some tropical energy from the south and drenching the western Great Lakes. The two bits of energy are also attached to parallel jet streaks, which are boosting the energy but hampering the mobility of the feature.
The leading band of rain is diminishing over Indiana and northwest Ohio tonight, and will wear itself out
through the morning hours tomorrow. The trailing cold front will be dragged into the region later in the day Friday, arriving in the predawn on Saturday. By this point, low pressure will be developing over the central Rockies, with a warm front rising towards the Ohio Valley by the late evening, bringing a chance for steadier rain to the region after a cooler day beforehand.
