@dbmet It is this weather station:
We received this notice from Aeris:
"Specifically, there was a bug in the API in which it would override the TotalMM would be overridden by the 24 hour max value. This is what occurred on the 21st below that you see. The team has already fixed this, and is actually included in the 1.3.4 updates they are pushing out this afternoon."
So it sounds like they kept dragging along the total precipitation value even though it hadn't changed for awhile. According to them this has been fixed and pushed out this afternoon.
Please let us know if you have any other questions or feedback. Thanks!
