***1:45am UPDATE***My driveway (and most sidewalks/untreated streets in Louisville) is a sheet of ice and we're still awaiting another big batch of freezing rain in Louisville. That precipitation should be here within minutes and we'll continue to see freezing rain fall until around 7am or just before. Temperature at my house is 26.7 °F and the airport is still holding at 27 °F. You have to go down to Bowling Green, KY to find temperatures just above freezing, so I don't think any relief in the form of warmer air will make it here in time to spare the morning commute in Louisville. Still some snow falling to our north and east, but it's transitioning to sleet/freezing rain as warmer temperatures aloft work their way northward. I still think we're on track to get somewhere near 0.5" of accumulated ice here in the Metro, especially since radar returns are filling in to our west.
No word on school cancellations in Louisville yet (JCPS says they'll make a decision at 4am), but I'm already seeing reports of slick roads in the suburbs. It's 25 degrees here at my house and 27 at the airport, so the liquid rain that's falling from the sky is freezing on the surface. Needless to say, things are going to be very slick on those untreated roads in the Metro tomorrow if temperatures continue to stay below 32 at the surface with freezing rain tonight.
