Still looks like mostly rain changing to a brief period of light snow overnight. The snow shouldn't be to much of a problem on the roadways due to the warmer temperatures today, but of course do be careful tonight as most roadways will be wet.
The weekend clipper doesn't look like to much of a snow maker. The latest 12Z GFS puts this storm system to our north, but it will bring most of Kentuckiana some very light snow Saturday into Saturday night. As of right now, no major accumulation is expected.
UPDATE ON MONDAY/TUESDAY SYSTEM
As I mentioned yesterday, the next potential major storm system to affect the Ohio Valley Region will be next Monday and Tuesday. The 12Z GFS does place colder air over the region, allowing for some of the precipitation to be snow. Let's take a trip through the GFS since this is the most optomistic for snow next week...

144 hour/Tuesday Morning
On Tuesday morning, precipitation has made it well into the state, but that blue line is the freezing line about 5,000 feet above the surface, and as you can see that is north of us. What that means is mainly rain would be falling Tuesday morning.
150 hour/Tuesday afternoon
Tuesday afternoon, precipitation has overspread the region and some of it is heavy. The blue freezing line is still north of us, so precipitation probably rain, but maybe some sleet beginning to mix in.
156 hour/Late Tuesday afternoon
Later during Tuesday afternoon, the freezing line drops just south of Lousiville. What this would mean is mainly snow for Southern Indiana and a mix along the Ohio River, with rain south of Louisville. Their is still plentiful precipitation left over after the temperature drops below freezing. What that would mean is the first accumulating snow/ice for Southern Indiana and a close call for Northern/Central Kentucky. Again, this is only one computer model, and many are still having trouble putting this storm north or south of the region. If you want snow here in Kentuckiana, typically you want the low to track across Eastern Kentucky, west of the Appalachian Mountains. Personally, I would like to see that freezing line well south, but it's to close for comfort. Obviously this particular computer model will jump all over the place, as well as others, but I will be running through the GFS everyday and other models as we near closer to the storm. I think this does have rather significant winter storm potential somewhere across the Midwest. According to the 12Z run of the GFS, someone would be in for a rather nasty ice storm, ending off with some snow. Something to keep an eye on the next several days, but let's not get to excited yet, as many storms this time of year trend further north giving us mainly rain. Hopefully we will see some computer model agreement over the next several days, and maybe just maybe this one is for Kentuckiana! STAY TUNED!
