Looking at the SPC Mesoscale analysis, there are no upper-level shortwaves that will cause any lifting motion for storm development. Also, there is a surface high pressure system that is sitting right over Indiana and Illinois that is retaining very dry, cold, and stable air around the area. Surface temperatures are well below freezing ranging from 4-10 degrees Fahrenheit over the Midwest region.
Skies are clear with southwesterly winds and some scattered cirrus clouds. There is no temperature advection that would allow for any lift development. However, at the 500mb level there is a jet streak over northern and central Indiana which could cause lift but with little to no moisture at the surface and 700mb level, storm development is highly unlikely.
