Winter Storm Warning for Louisville

Well, it looks like another potentially major winter storm is likely to hit the Louisville area this evening into tomorrow morning. It looks like snow will develop around 4 pm this afternoon. Then, overnight, as warmer temperatures move into the higher levels of the atmosphere, the snow will changeover to sleet and freezing rain. Depending on the track of the low pressure system that will be bringing the inclement weather to the region, Louisville will experience a changeover to plain rain by morning. Temperatures have to rise a good 10 degrees from where they are now for that to happen. I'm a bit skeptical, but I believe the transition to rain will take place some time Tuesday morning. We may expect to see 2 to 4 inches of snow and sleet to accumulate before the changeover to freezing rain, which may coat trees and power lines with a tenth to a quarter of an inch of ice. It may be more if the transition to plain rain doesn't occur. Temperatures will top out in the 30s tomorrow, but how much above freezing will that be? I should be able to check in tomorrow morning to analyze the storm potential even more. But beforehand, a Winter Storm Warning is in effect for Louisville until noon tomorrow. The temperature means everything regarding this storm, as it does for any major winter storm. We've had no problem rising above freezing in other winter storms this season, but we'll see if this one's any different. More later...
