Our latest winter storm is running into relatively warm temperatures, so many areas will start with rain, then switch to snow. Areas north of I-64 will be under cooler air for longer, thus more snow is expected over S. Indiana and northern Kentucky. These areas are under a Winter Storm Warning from Paoli to Madison in Indiana, south to Clark County and over to Oldham, Trimble, and Henry Counties in Kentucky. Everywhere else is under a Winter Weather Advisory.
Follow along with the maps below to track the mix of rain and snow through the evening. The more rain we see in Louisville and areas to the south, the less snow accumulation. Below are two weather model forecast maps, the RPM showing 0-3" amounts, and the NAM showing 0-5" totals. Areas south of E-town will likely see little to no accumulation with mainly rain. The bottom map is my snowfall total map. Don't be overly surprised to see pockets of up to 5" in north/northeast of Louisville.
Roads will likely start wet, then slushy, then briefly snow-covered. Watch for icy roads overnight with lows in the single digits and teens. Drying out for all areas after midnight!
