Upcoming rain expectations

This is from NOAA, NWS. Now, I must admit, I have a bit of trouble with the math on this one. Rain is predicted to start Wednesday, and the (6 day) totals are to Sunday at 4 am. No matter how I count it, I don’t get six days out it – 4 … or 5, if one counts Sunday to 4 am as a full day. Anyway, the visual is a nice encapulation of what we can expect.
