Another winter storm is on the way to the tri-state area and this one looks very messy! Whereas the storm over the weekend brought light, powdery snow with liquid to snow ratios of 20:1, this next storm will be a wintry mix of sleet, freezing rain and wet snow. The good news is that this system appears to be a fairly fast moving, short lived system. Still this one could be one to watch, as road conditions on Thursday could get very hazardous.
Right now a low is forming over the Oklahoma panhandle and is predicted to move into the Tennessee Valley overnight on Wednesday and into Thursday. While temperatures here at the surface will stay below or near freezing, as the winds shift to the south, temperatures aloft in the upper layers of the atmosphere will rise into the 30s, producing sleet, freezing rain and wet snow over our area.
So what can we expect? The further north you go, the better off you will be. Here in Dubois County, I don't think freezing rain will be a major play at this time. The latest models are showing the freezing rain south of the Ohio River. Right now if these current models verify, we're looking at a sleet/snow event. Don't expect much in accumulations. Just expect a mess! South of here, look for freezing rain and sleet changing over to an all rain event in Kentucky.
So what can we expect as a timeline? The National Weather Service has issued a Winter Weather Advisory for our area, effective at 7pm Wednesday evening going through Thursday. It looks like the bulk of the precip will start after dark on Wednesday, with the main event between 5am - Noon on Thursday. No matter what we get, when we get it, it's gonna be a mess! Stay safe out there. I'll have more updates tomorrow. For now, here's your updated 7 day outlook.
