I usually just watch thegreatmorel.com sightings map. It looks like the unseasonably warm winter brought the ground temps high enough in the southern part of Indiana, but that shut down with the current temps over the last week.
They'll probably be right on schedule in your area within the next couple of weeks.
I live about two hours northwest of you, so I don't expect them for at least 2- 3 weeks.
I do soil temperature testing on the south facing slopes of wooded areas, just an inch out two before the surface. When the average temp gets to be around 11°C-12°C (52°F-54°F) they usually make their appearance.
