I think we can all agree that Michigan City, Indiana is a strange name for a town that is part of the greater Chicagoland region, yes?
At 255PM, ET, Michigan City was reporting a temperature of 39 degrees with clear skies. A brisk flow is coming off of Lake Michigan, a true lake breeze flowing from the colder dense air to relatively warm air of northern Indiana, absent of prevailing synoptic flow. Temperatures were about 5 or 6 degrees warmer away from the Lake.
A broad ridge aloft is helping the southern Great Lakes to dry out, and it should be a fairly pleasant middle of the week in Michigan City. A broad area of low pressure in the Rockies and High Plains bears watching, however. It will be slow in transpiring, but low pressure will develop at the surface through the day on Saturday. Precipitation will arrive in Michigan City late on Thursday. It is likely to be a chilly rain, but given the uncertainty wrought by the lateness in development of this feature, snow cannot be left out of the forecast.

I think you can see some of the uncertainty with the model guidance showing up in the forecast. The models aren’t spread over a wide range, but without any thing fully developed yet, there is a lack of precipitation commitment. Look how clear it is right now! And you’re telling me it might snow?
