Overrunning patterm has set up across the Ohio and Tennessee Valleys. The column looks like it will have no problem saturating across the southern counties of the viewing area (i.e. south of the Western Ky and Bluegrass pkwys) but north closer to the Ohio River (including the metro) there is a ton of dry air in place in the low levels, and it appears the dry air is going to win out.
So this is what we re looking for... a wintry mix of rain/sleet/snow developing for the southern regions of the viewing area. Still the potential for a couple of inches of wet snow (keep in mind the ground temps are pretty warm) mainly on grassy areas. This would include places like... Greensburg, Campbellsville, Lebanon, Hodgenville etc... Closer to Louisville, a few flurries or even a period of light snow may make it to the ground - but overall the dry air looks like it's going to be just a little to much to overcome so little / no accumulation expected.
This pattern continue into weekend but the column will warm substantially so all precip will be in the form of liquid.
Check out both the 06z snowfall outputs from the GFS and NAM. Amounts vary some but the placement is pretty much the same.
stay warm all
