The clouds are moving in today with precipitation on the way. Late this afternoon or perhaps early this evening we will start to see a mix of rain/sleet/freezing rain. The freezing rain could be the most problematic because of the possible ice accumulation on some roads... especially bridges and overpasses. A WINTER WEATHER ADVISORY goes into effect at 6pm for counties north of I-64 due to the potential for ice tonight.
The precip could start out as sleet and rain first, then change over to freezing rain after sunset. Some areas in Southern Indiana could see an extended period of time with freezing rain. Because of this, Indiana is most likely to see ice accumulation; however, it still looks to be a tenth of an inch or less.
Elevated roadways (like bridges and overpasses) are most likely to see ice accumulation or icy spots. It doesn't take much ice to cause major problems on the roads, so be on high alert if you have to drive later tonight or during the overnight period.
The good news is that the temperatures will warm up as we head through the morning. By the morning rush hour, all ice will be melted and precip will be in the form of rain. We still expect wet roads, but if the timing plays out as we expect it, the roads won't be icy after 6am tomorrow morning.
Southern Indiana will be most impacted by the ice and most likely to see accumulation. Counties bordering the Ohio River may see some icy spots on the roads which could cause minor problems. Folks to the south of Louisville may see some sleet during the late afternoon/early evening, but the precip will change over to rain shortly after it begins, so no problem are expected there besides wet roads.
