The map above is the expected rainfall over the next 7 days. As you can see, Southern Lower Michigan is not expected to have any measurable rainfall. Only light amounts are expected in N. Lower Michigan, generally north of US 10, where a light shower is possible either Monday night or Tuesday night.
Heavy rainfall is likely later this week as Hurricane Delta comes ashore late this week. There will also be significant rainfall in the West, which will be helpful to those still fighting wildfires.
