It’s time for a forecast, dear friends, so lets head on down to the Ohio Valley.
At 756PM, Louisville was reporting mostly clear skies with a temperature of 54 degrees. Parts of the region that saw a little bit of the sun before it set popped to nearly 60, but eastern Kentucky is still socked in, and sits in the upper 40s, with Louisville straddling the line. A deeply occluded low in the Great Lakes was tied to a slow moving low in the Appalachians, and the combination of the two was responsible for the cloud deck slowly departing the Louisville area.
The low is wrapping in additional mid level moisture that, within the colder air behind the system, is more inclined to produce some cloud cover. This is the regime that Louisville will find itself within for the remainder of the work week, with passing midlevel clouds passing in front of a seasonably cool sunshine. A perturbation moving through the southern Plains, riding the northern edge of a jet streak will approach late on Friday, but rain will hold off until the weekend.

When there are no changes in air mass, and the sun is more or less out for the day, you end up with some pretty similar forecasts. Here is the satellite imagery, showing the last of the significant clouds and snow to Louisville’s southeast, and some less ominous clouds closer to Lake Michigan.
