Nighttime microphysics satellite imagery shows a plume of cirrus extending across western KY and southern IN at this hour, with a few low- and mid-level convective debris clouds also being observed.

Temperatures across the area exhibit a 10-15 degree split between urban areas/ridgetops and rural areas/valleys.
As we head through the rest of the night, an area of mid-level moisture will continue to linger across western KY and southwest IN, with greater low-to-mid level cloud cover into Friday morning.
