Air temperatures (the ones we speak of all the time) are measured about six feet above the surface, so although those air temps will be right around freezing or only slightly below it tonight… the actual temperatures at the surface may lag a few degrees, given the recent sub-zero chill and snow pack. So the Winter Weather Advisory is “grounded,” if you will, in that possibility. This shouldn’t be a threat to power lines and trees higher up, but any un-treated surface, such as sidewalks, parking lots, and minor roads, could ice up overnight into Tuesday morning. Road temperature models don’t show temps much below freezing, so main/treated roads probably won’t be a huge problem. Freezing rain will arrive across northwestern Indiana first this evening with additional ice accumulations expected through the night. So: heads up first around Lafayette, then the rest of central Indiana after about 10pm tonight. Freezing rain will then transition to rain through mid to late Tuesday morning.
