>>>3pm Monday update<<<
Just looking at newest data: Could be a dusting in the northern 1/3 of Indiana Tuesday morning, including rush hour. Not so much in the Indy Metro.
For the Wed/Thu/Fri time period: no big change. Light mix Wed pm and eve possible…best freezing rain chance along and northeast of I-74. Mix would be moving northeast out of area during drive time Thursday morning as things change to all rain….and intensify. Could be an inch of rain Christmas Eve afternoon and evening. Turning colder, with snow showers Christmas Day.

Some side streets could be slippery this morning after last night’s light snow. Indianapolis measured .6 inches by midnight.
I don’t think we’ll have any major weather related travel problems in Indiana through the Wednesday morning drive. That big storm hitting for the holiday will start to bring precipitation chances into the area Wednesday afternoon. The types of precip could change if the center of low pressure moves differently, but one thing’s for sure–much of the East, and northern Plains will get “something” for holiday travel.
The system will first deliver warmer air aloft, before the surface temperatures warm above freezing. The warming will move from southwest to northeast. It may already be above freezing from Indianapolis southwest when the stuff starts Wednesday afternoon, and will probably stay that way Wednesday night. But any area northeast of a line from (roughly) Lafayette to Indy to Cincy should be ready for slick spots later Wednesday.
All of central Indiana should be warm enough for plain rain by mid morning Thursday. The amounts Wednesday afternoon and evening should be light. The big moisture will come as rain Thursday afternoon into Christmas Eve night.
White Christmas? Sorta kinda. Rain showers should change over to snow showers on the Big Day, and there could be some light accumulation.
