The New York Times data for Michigan at us-covid-tracker dot com is anomalous. It adds "probable cases" data starting Jun 5 which the State of Michigan COVID-19 Dashboard does not.
Michigan's data shows no up-trend to cases at all, and in fact shows new daily cases trending lower over the period.
"The Michigan Department of Health and Human Services reported 284 new cases of COVID-19 Monday, bringing the total to 58,525 [both data points are for Fri 6/5/20]. The state also started reporting probable cases; there are 4,928 cases that are not confirmed yet."
